(1)  The number of shares of Common Stock, par value $.01 per share ("Ahmanson
     Common Stock"), of H. F. Ahmanson & Company to be registered pursuant to
     this Registration Statement is based upon the number of shares of Common
     Stock, par value $.01 per share ("Coast Common Stock"), of Coast Savings
     Financial, Inc. presently outstanding or reserved for issuance under
     various plans or otherwise expected to be issued upon the consummation of
     the proposed transaction to which this Registration Statement relates,
     multiplied by the exchange ratio of 0.8082 shares of Ahmanson Common Stock
     for each share of Coast Common Stock.

(2)  Pursuant to Rules 457(f) and 457(c) under the Securities Act of 1933, as
     amended, the registration fee is based on the average of the high and low
     sales prices of Coast Common Stock, as reported by the New York Stock
     Exchange on November 28, 1997 ($60.3125), and computed based on the
     estimated maximum number of such shares (19,788,532) that may be exchanged
     for the Ahmanson Common Stock being registered.

(3)  A registration statement fee of $352,081.28 is payable hereunder; however,
     a registration fee of $221,697.12 was previously paid in connection with
     the filing by Coast of preliminary proxy solicitation materials, under
     Section 14(g) and Rule 0-11(a)(2) of the Securities Exchange Act of 1934,
     as amended, which fee, pursuant to Rule 457(b) under the Securities Act of
     1933, as amended, has been credited against the registration fee payable
     hereunder.

                                EXPLANATORY NOTE

         This Registration Statement on Form S-4 is being filed (i) in
connection with the registration and issuance of shares of common stock, par
value $.01 per share, of H.F. Ahmanson & Company, a Delaware corporation (the
"Registrant"), in connection with the proposed merger (the "Merger") of Coast
Savings Financial, Inc. ("Coast") with and into the Registrant pursuant to an
Amended and Restated Agreement and Plan of Merger, dated as of October 5, 1997,
and (ii) in connection with a special meeting of stockholders of Coast to be
held in connection with the Merger. It is expected that a registration statement
on Form S-1 (the "Form S-1") will be filed at a later date by a trust to be
formed by Coast for the purpose of registering such trust's securities. It is
expected that the Form S-1 will contain a description of the trust's securities
and of the trust itself, which will be formed by Coast in connection with
providing Coast's stockholders with an amount equal to any proceeds (net of
taxes calculated based on certain assumptions and expenses) from certain
litigation claims of Coast Federal Bank, FSB against the United States
government. Prior to the special meeting of Coast stockholders referred to
above, Coast stockholders will receive information including a proxy
statement/prospectus to be included in this Registration Statement, as it may be
amended or supplemented, and a prospectus to be included in the Form S-1, as it
may be amended or supplemented.

                [Coast Savings Financial, Inc. Letterhead & Logo]


                                                                          [date]


Dear Stockholder:

               It is my pleasure to invite you to attend a Special Meeting of
Stockholders of Coast Savings Financial, Inc. ("Coast") to be held on
____________, at ______________ a.m., at ________________________, Los Angeles,
California.

               At this very important meeting, Coast stockholders will be asked
to consider and vote upon a proposal to approve the Amended and Restated
Agreement and Plan of Merger (the "Merger Agreement"), dated as of October 5,
1997, by and between Coast and H. F. Ahmanson & Company, a Delaware corporation
("Ahmanson"), and the transactions contemplated thereby, including the merger
(the "Merger") of Coast with and into Ahmanson.

               If the Merger is approved and consummated, each share of Coast
common stock will be converted into the right to receive 0.8082 of a share of
Ahmanson common stock. In addition, immediately prior to the Merger each Coast
stockholder will receive one Contingent Payment Right Certificate (a "CPR
Certificate") for each of their shares of Coast common stock. The CPR
Certificates will be issued by the newly-formed Coast Federal Litigation
Contingent Payment Right Trust (the "CPR Trust"). Upon consummation of the
Merger, Ahmanson will be contractually bound to pay to the CPR Trust, for the
benefit of the holders of CPR Certificates, an amount equal to any proceeds (net
of taxes and expenses, computed under certain assumptions as described in the
accompanying Proxy Statement/Prospectus), that Coast Federal Bank, FSB ("Coast
Federal") (or its successors) may receive from its pending litigation claims
against the United States government relating to the government's alleged breach
of its agreement with respect to the permanent addition of approximately $299
million to Coast Federal's regulatory capital. Thus, in connection with the
Merger you will both receive Ahmanson common stock and retain an indirect
proportionate interest in our litigation claims against the government. The CPR
Certificates will be transferable[, and it is anticipated that they will be
included in the NASDAQ National Market System,] but no assurance can be given
that an active market for the CPR Certificates will develop or be sustained. The
CPR Certificates are highly speculative securities that involve a high degree of
risk.

               THE BOARD OF DIRECTORS OF COAST (THE "COAST BOARD") HAS
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED
THEREBY, AND BELIEVES THAT THE MERGER IS IN THE BEST INTERESTS OF COAST AND ITS
STOCKHOLDERS. THE COAST BOARD RECOMMENDS THAT ALL STOCKHOLDERS VOTE "FOR" THE
MERGER PROPOSAL. Coast's financial advisor, Goldman Sachs & Co., has issued its
written opinion to the Coast Board of Directors that the consideration to be
received by holders of Coast common stock pursuant to the Merger Agreement is
fair from a financial point of view to Coast stockholders.

               COAST STOCKHOLDERS ARE URGED TO READ CAREFULLY THE ACCOMPANYING
NOTICE OF SPECIAL MEETING AND PROXY STATEMENT/PROSPECTUS, WHICH CONTAIN
IMPORTANT INFORMATION ABOUT THE MERGER AND THE OTHER TRANSACTIONS CONTEMPLATED
BY THE MERGER AGREEMENT, INCLUDING IMPORTANT INFORMATION CONCERNING THE CPR
TRUST AND THE CPR CERTIFICATES. A COPY OF THE OPINION OF GOLDMAN, SACHS & CO. IS
ATTACHED AS APPENDIX D TO THE PROXY STATEMENT/PROSPECTUS ENCLOSED HEREWITH AND
SHOULD BE READ IN ITS ENTIRETY.

               Regardless of the number of shares you own, or whether you plan
to attend the meeting, it is very important that your shares be represented and
voted at the meeting. Since the affirmative vote of a majority of the
outstanding shares is required for approval of the Merger Agreement and the
transactions contemplated thereby, a failure to vote is the same as a vote
against the Merger. Please read the enclosed material carefully and complete,
sign and return the enclosed proxy in the envelope provided as soon as possible.

               On behalf of the Coast Board of Directors, I thank you for your

Agreement and the transactions contemplated thereby.

                 SUBJECT TO COMPLETION, DATED DECEMBER 5, 1997
                PROXY STATEMENT OF COAST SAVINGS FINANCIAL, INC.

                                  PROSPECTUS OF
                            H. F. AHMANSON & COMPANY

                                  COMMON STOCK
                           (PAR VALUE $.01 PER SHARE)

                                 ---------------


        This Proxy Statement/Prospectus is being furnished to holders of common
stock, $.01 par value ("Coast Common Stock"), of Coast Savings Financial, Inc.,
a Delaware corporation ("Coast"), in connection with the solicitation of proxies
by the Board of Directors of Coast (the "Coast Board") for use at a Special
Meeting of stockholders to be held on _________, 199_, at ____ a.m., at
_______________, Los Angeles, California and at any adjournments or
postponements thereof (the "Special Meeting").

        The purpose of the Special Meeting is to consider and vote upon a
proposal to approve an Amended and Restated Agreement and Plan of Merger, dated
as of October 5, 1997 (the "Merger Agreement"), by and between Coast and H. F.
Ahmanson & Company, a Delaware corporation ("Ahmanson"), and the transactions
contemplated thereby, including the approval of the merger of Coast with and
into Ahmanson (the "Merger"), the establishment of and the terms of a trust to
be known as the Coast Federal Litigation Contingent Payment Right Trust (the
"CPR Trust"), the CPR Certificate Distribution (as defined herein), the
engagement of the Litigation Trustees (as defined herein) (including the terms
of their engagement) for the CPR Trust, the terms of the Commitment (as defined
herein) and the rights of the holders of CPR Certificates (as defined herein).
See "Summary" and "The Merger" and Appendices A and C to this Proxy
Statement/Prospectus.

        Upon consummation of the Merger, each outstanding share of Coast Common
Stock, together with each associated Coast Right (as defined herein), shall
cease to be outstanding and each such share (other than (a) certain shares, if
any, held by Coast, Ahmanson or their subsidiaries and (b) shares, if any, held
by holders of Coast Common Stock ("Dissenters' Shares") who perfect their rights
to dissent from the Merger) shall be converted into and exchanged for 0.8082 of
a share (the "Exchange Ratio") of common stock, par value $.01 per share, of
Ahmanson ("Ahmanson Common Stock") (together with the appropriate number of
Ahmanson stock purchase rights ("Ahmanson Rights") issued as provided in the
Ahmanson Rights Plan (as defined herein)), with cash paid in lieu of fractional
shares. In addition, and as additional consideration to be received by the Coast
stockholders in the Merger, at or prior to the Effective Time (as defined
herein), Ahmanson will enter into the Commitment with the CPR Trust. See "The
Merger."

        Pursuant to the Merger Agreement, at or prior to the Effective Time,
Ahmanson will enter into a contractual commitment (the "Commitment") with the
CPR Trust pursuant to which Ahmanson will be obligated to pay to the CPR Trust
from time to time an aggregate amount equal to the Commitment Amount. Generally,
the Commitment Amount is an amount equal to the proceeds, if any, received by
Ahmanson, Coast Federal or Ahmanson's subsidiary, Home Savings of America, FSB
("Home Savings") (or any other successor), as a result of the Litigation, net of
assumed tax liabilities attributable to such receipt (calculated on certain
assumptions described herein), certain expenses and interest, plus the amount of
certain assumed tax benefits (calculated on certain assumptions described
herein) to Ahmanson, if any, associated with payments under the Commitment, all
as more fully described herein. See "The Merger--Merger Consideration; Exchange
Ratio; Commitment." The Commitment will rank pari passu with other senior
indebtedness of Ahmanson. The Litigation will remain an asset of Coast Federal
and its successors.

        This Proxy Statement/Prospectus also constitutes a prospectus of
Ahmanson in respect of the shares of Ahmanson Common Stock to be issued to
stockholders of Coast in connection with the Merger and, following consummation
of the Merger, in respect of any shares of Ahmanson Common Stock that are
issuable upon exercise of Replacement Options (as defined herein). Based on the
[ ] shares of Coast Common Stock outstanding on the Record

                                                    (continued on the next page)

              PROXY STATEMENT/PROSPECTUS. ANY REPRESENTATION TO THE

                      THE SHARES OF AHMANSON COMMON STOCK

SPECIAL MEETING; RECORD DATE

        The Special Meeting will be held at ____ a.m., on _______, _____ __,
199_, at _______________ ________________, Los Angeles, California. At the
Special Meeting, Coast stockholders will consider and vote upon approval and
adoption of the Merger Agreement and the transactions contemplated thereby,
including the approval of the Merger, the establishment of and the terms of the
CPR Trust, the CPR Certificate Distribution, the engagement of the Litigation
Trustees (including the terms of their engagement) for the CPR Trust, the terms
of the Commitment and the rights of the holders of CPR Certificates
(collectively, the "Transaction Proposal").

        The Coast Board has fixed the close of business on ________ __, 1997, as
the record date for determining the Coast stockholders entitled to receive
notice of and to vote at the Special Meeting (the "Record Date"). As of the
Record Date, _____ shares of Coast Common Stock were issued and outstanding and
entitled to be voted at the Special Meeting. For additional information with
respect to the Special Meeting, including the Record Date and vote required for

THE MERGER

        GENERAL.

        The Merger Agreement provides that Coast will merge with and into
Ahmanson, which will be the surviving corporation in the Merger and will be
governed by the laws of the State of Delaware. If the Transaction Proposal is
approved at the Special Meeting, all required governmental and other consents
and approvals are obtained and all the other conditions to the obligations of
the parties to consummate the Merger are either satisfied or waived (if
permitted), the CPR Certificate Distribution will be effected and, immediately
thereafter, the Merger will be consummated. In addition, Ahmanson will enter
into the Commitment with the CPR Trust at or prior to the Effective Time and
effective at the Effective Time. A description of the Commitment and the related
Commitment Amount are more fully set forth below under "--Commitment" and "The
Merger--Merger Consideration; Exchange Ratio; Commitment." A copy of the Merger
Agreement and a copy of the form of Commitment are set forth as Appendices A and
C to this Proxy Statement/Prospectus, respectively. See "The Merger."

        MERGER CONSIDERATION.

        The merger consideration (the "Merger Consideration") pursuant to the
Merger Agreement consists of (a) the shares of Ahmanson Common Stock issuable in
exchange for shares of Coast Common Stock pursuant to the Merger Agreement, and
cash in lieu of fractional share interests, and (b) the entering into of the
Commitment by Ahmanson.

        EXCHANGE RATIO.

        At the time of the Merger, each outstanding share of Coast Common Stock
(other than (a) certain shares, if any, held by Coast, Ahmanson or their
subsidiaries and (b) Dissenters' Shares, if any) will be converted into and
exchanged for 0.8082 of a share of Ahmanson Common Stock (together with the
appropriate number of Ahmanson Rights as provided in the Ahmanson Rights Plan).
No fractional shares of Ahmanson Common Stock will be issued. Rather, cash
(without interest) will be paid in lieu of any fractional share interest to
which any Coast stockholder would be entitled upon consummation of the Merger,
determined by multiplying such fraction by the average of the last sale prices
of the Ahmanson Common Stock, as reported by the NYSE Composite Tape (as
reported in The Wall Street Journal or, if not reported therein, in another
authoritative source) for the five NYSE trading days immediately preceding the
Effective Date.

        COMMITMENT.

        Ahmanson will enter into the Commitment, substantially in the form
attached hereto as Appendix C, with the CPR Trust at or prior to the Effective
Time and effective at the Effective Time. Immediately prior to the Effective
Time, and provided that all other conditions to consummation of the Merger have
been either satisfied or waived (if permitted), the CPR Certificates will be
distributed to the Coast stockholders (and to the other persons specified in the
Merger Agreement and described herein under "The Merger--The CPR Trust, the CPR
Certificates and the CPR Certificate Distribution"). The Commitment will
obligate Ahmanson to pay to the CPR Trust from time to time an aggregate amount
equal to the Commitment Amount. As used in this Proxy Statement/Prospectus, the
Commitment Amount means an amount equal to the Litigation Proceeds (as defined
herein) minus the Reimbursements (as defined herein) plus the Assumed Tax
Benefit (as defined herein). Litigation Proceeds means any and all cash payments
actually received by Coast Federal or Home Savings or any of their affiliates
(the "Ahmanson Group") pursuant to a final, non-appealable judgment or a final
settlement of the Litigation (the "Cash Proceeds") and the non-cash payments, if
any, actually received by the Ahmanson Group pursuant to a final, non-appealable
judgment or a final settlement of the Litigation (the "Non-Cash Proceeds").
Reimbursements means (a) an amount equal to the Expense Fund (as defined herein)
plus (b) interest on the portions of the Expense Fund withdrawn by the CPR Trust
calculated from the time of any such withdrawal at an annual interest rate equal
to the Reference Rate of Bank of America (the "Reference Rate") in effect from
time to time plus 250 basis points, compounded quarterly plus (c) the Assumed
Tax Liability (as defined herein) plus (d) in the event Litigation Proceeds are
required to be included in income for federal income tax purposes in a taxable
year prior to the year such proceeds are received in cash (either because of the
accrual of Cash Proceeds before the payment thereof or the time required to
liquidate Non-Cash Proceeds), interest at the Reference Rate plus 250 basis
points from the date of such payment of taxes to the date of receipt of cash.
The Expense Fund means an amount equal to $20 million, less the expenses
relating to the Litigation incurred and paid between August 31, 1997 and the
Effective Date, which amount Ahmanson will deposit at the Effective Time in a
non-interest bearing demand-deposit account in the name of the CPR Trust at Home
Savings. Subject to certain exceptions, the Assumed Tax Liability will be
computed on the assumption that the Litigation Proceeds will be includible in
the Ahmanson Group's gross income as ordinary income in full at the highest net
marginal federal, state and local income tax rate. For additional information
concerning the Commitment, the Commitment Amount and related matters, see "The
Merger--Merger Consideration; Exchange Ratio; Commitment."

        VOTE REQUIRED.

        Approval of the Transaction Proposal requires the affirmative vote of a
majority of the outstanding shares of the Coast Common Stock entitled to vote at
the Special Meeting. As of the Record Date, the directors and executive officers
of Coast and their affiliates held _______ shares (or approximately ____% of the
outstanding shares) of Coast Common Stock, not including unissued shares deemed
beneficially owned pursuant to outstanding Coast Stock Options. As of the Record
Date, Ahmanson held ___ shares of Coast Common Stock and directors and executive
officers of Ahmanson and their affiliates held ___ shares of Coast Common Stock.
See "General Information--Vote Required" and "The Merger--Interests of Certain
Persons in the Transaction Proposal."

        Approval of the Merger Agreement by holders of Ahmanson Common Stock is
not required under the Delaware General Corporation Law ("DGCL") or the rules of
the NYSE. See "General Information--Vote Required."

        RECOMMENDATION OF THE COAST BOARD.

        The Coast Board believes that approval of the Merger Agreement and the
transactions contemplated thereby, including the approval of the Merger, the
establishment of and the terms of the CPR Trust, the CPR Certificate
Distribution, the engagement of the Litigation Trustees (including the terms of
their engagement) for the CPR Trust, the terms of the Commitment and the rights
of the holders of CPR Certificates, is in the best interests of Coast and its
stockholders and unanimously recommends that the stockholders of Coast vote
"FOR" approval




                                      -9-
<PAGE>   17

of the Transaction Proposal. The Coast Board has unanimously approved the
Transaction Proposal. In deciding to approve the Transaction Proposal, the Coast
Board considered a number of factors, including the financial condition, results
of operations and future prospects of Coast and Ahmanson. See "The
Merger--Background of the Merger" and "--Reasons of Coast for the Merger." As a
result of the difficulty in establishing the value of the Litigation for
purposes of the Merger, the Coast Board determined that the ultimate value of
the Litigation should be retained by Coast's stockholders in connection with the
Merger and, thus, the Coast Board, as an integral part of its approval of the
Transaction Proposal, approved the establishment of the CPR Trust, the terms of
the CPR Certificates and the Commitment, the CPR Certificate Distribution and
related matters. See "The Merger--Interests of Certain Persons in the
Transaction Proposal."

        THE COAST BOARD UNANIMOUSLY RECOMMENDS THAT COAST STOCKHOLDERS
VOTE "FOR" APPROVAL OF THE TRANSACTION PROPOSAL.

        OPINION OF COAST'S FINANCIAL ADVISOR.

        Goldman, Sachs & Co. ("Goldman Sachs"), Coast's financial advisor, has
rendered its written opinion, dated October 5, 1997, to the Coast Board to the
effect that, as of such date, based on and subject to the matters set forth in
such opinion, the proposed Consideration (as defined herein) to be received by
the holders of Coast Common Stock was fair from a financial point of view to the
Coast stockholders. Goldman Sachs has confirmed its October 5, 1997 opinion as
of the date of this Proxy Statement/Prospectus by delivery of its written
opinion to the Coast Board, dated the date hereof. For additional information,
see "The Merger--Opinion of Coast's Financial Advisor." The opinion of Goldman
Sachs, dated the date of this Proxy Statement/Prospectus, is attached as
Appendix D to this Proxy Statement/Prospectus. Holders of Coast Common Stock are
urged to read such opinion in its entirety for descriptions of the procedures
followed, matters considered and limitations on the reviews undertaken in
connection therewith.

        EFFECTIVE TIME.

        If the Transaction Proposal is approved by the requisite vote of the
Coast stockholders, all required governmental and other consents and approvals
are obtained and the other conditions to the obligations of the parties to
consummate the Merger are either satisfied or waived (if permitted), the CPR
Certificate Distribution will be effected on the Effective Date with a record
and payment date on the Effective Date immediately prior to the Effective Time
and the Merger will be consummated and will become effective on the date (the
"Effective Date") and at the time (the "Effective Time") that a certificate of
merger is filed with the Secretary of State of the State of Delaware or at the
time specified in such certificate. The Commitment will be entered into by
Ahmanson at or prior to the Effective Time and effective at the Effective Time.

        Unless otherwise agreed by Coast and Ahmanson, and subject to the
conditions to the obligations of the parties to effect the Merger, the parties
have agreed to cause the Effective Date to occur on the fifth business day to
occur after the last of the conditions to the consummation of the Merger have
been satisfied or waived (or, at the election of Ahmanson, on the last business
day of the month in which such date occurs or, if such date occurs on one of the
last five business days of such month, on the last business day of the
succeeding month). Ahmanson and Coast each has the right, acting unilaterally,
to terminate the Merger Agreement should the Merger not be consummated by June
30, 1998 (unless the failure to consummate the Merger is a result of a breach by
the party seeking to terminate). See "The Merger--Effective Time" and
"--Termination; Termination Fee."

        DELIVERY OF AHMANSON CERTIFICATES.

        Promptly after the Effective Date, Ahmanson will send or will cause to
be sent transmittal materials to each record holder of shares of Coast Common
Stock outstanding at the Effective Time for use in exchanging those certificates
for shares of Ahmanson Common Stock and cash in lieu of fractional share
interests. See "The Merger--Distribution of Ahmanson Common Stock Certificates."

        CERTAIN FEDERAL INCOME TAX CONSEQUENCES.

        The Merger is intended to be a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986 (the "Code") with the
consequence that no gain or loss will be recognized for federal income tax
purposes by Coast or Coast stockholders as a result of the Merger except in the
case of a Coast stockholder (a) for gain that may be recognized in an amount not
exceeding the fair market value at the Effective Time of the CPR Certificates
received by such stockholder (which will include a proportionate share of the
value attributable to Ahmanson's having entered into the Commitment) and (b)
with respect to any cash received in lieu of fractional share interests.

        Consummation of the Merger is conditioned in part upon the receipt by
Ahmanson and Coast of opinions from their respective legal counsels that the
Merger will be a reorganization within the meaning of Section 368(a) of the
Code.

        All stockholders should carefully read the discussion of the material
federal income tax consequences of the proposed Merger under "The
Merger--Certain Federal Income Tax Consequences." In addition, stockholders are
urged to consult with their own tax advisers as to the federal, state, local and
foreign tax consequences in their particular circumstances.

        MANAGEMENT AFTER THE MERGER.

        Ahmanson will be the surviving corporation resulting from the Merger and
will continue to be managed by its current executive officers. Ahmanson has
agreed to cause Mr. Ray Martin, Chairman of the Board and Chief Executive
Officer of Coast, to be elected or appointed as a director of Ahmanson. See "The
Merger--Management and Operations After the Merger."

        INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION PROPOSAL.

        General. Certain members of Coast's management and the Coast Board have
interests in the Merger and the transactions contemplated thereby in addition to
their interests as stockholders of Coast generally. Those interests relate to,
among other things, provisions in the Merger Agreement regarding indemnification
and maintenance of directors and officers' liability insurance, the treatment of
outstanding Coast Stock Options and outstanding Coast Performance Share Awards
and Coast SARs with respect to Coast Common Stock, the appointment of Mr. Martin
as a director of Ahmanson, benefits to be paid to certain Coast executives in
connection with a change of control of Coast and the on-going role of certain
Coast executives in connection with the CPR Trust and their compensation in
connection therewith. See "The Merger--Interests of Certain Persons in the
Transaction Proposal" and "--Stock Options; Performance Share Awards; SARs"
below.

        CONDITIONS TO CONSUMMATION.

        Consummation of the Merger is subject to various conditions, including,
among other matters: (a) approval of the Transaction Proposal by the Coast
stockholders and notice from holders of no more than 5% of the outstanding
shares of Coast Common Stock that their shares of Common Stock be treated as
Dissenters' Shares; (b) receipt of all governmental and other consents and
approvals necessary to permit consummation of the Merger; (c) satisfaction of
certain other usual conditions, including the receipt of the tax opinions
discussed above; and (d) the establishment of the CPR Trust and the consummation
of the CPR Certificate Distribution, the execution and delivery of the
Commitment by Ahmanson and the transfer of the Expense Fund to the CPR Trust.
Under the terms of the Merger Agreement, certain conditions to the Merger may
generally be waived by Ahmanson or Coast, as applicable. See "The
Merger--Conditions to Consummation" and "--Amendment and Waiver."




                                      -11-
<PAGE>   19

        REGULATORY APPROVALS.

        The Merger is subject to the prior approval of the Office of Thrift
Supervision (the "OTS") and may be subject to the approval of or notice to other
regulatory authorities. An Application for approval of the Merger has been filed
with the OTS. There can be no assurance that the approval of the OTS will be
obtained or as to the timing or conditions of such approval. See "The
Merger--Regulatory Approvals."

        TERMINATION.

        The Merger Agreement may be terminated, and the Merger abandoned, at any
time prior to the Effective Time by mutual action of the board of directors of
both Coast and Ahmanson, or by action of the board of directors of either
company under certain circumstances, including if the Merger is not consummated
by June 30, 1998, unless the failure to consummate by such time is due to
knowing action or inaction of the party seeking to terminate, which action or
inaction is in violation of such party's obligations under the Merger Agreement.
Ahmanson may terminate the Merger Agreement if the Coast Board withdraws its
recommendation of the Merger or modifies or changes such recommendation in a
manner adverse in any respect to the interests of Ahmanson. If the Merger
Agreement is terminated under certain specified circumstances, and within 12
months after such termination Coast or any of its subsidiaries enters into a
definitive agreement with respect to an acquisition proposal by a third party,
Coast will be obligated to pay to Ahmanson a termination fee equal to $35
million. See "The Merger--Termination; Termination Fee."

        ACCOUNTING TREATMENT.

        Upon consummation of the Merger, Ahmanson will account for the
acquisition of Coast using the purchase method of accounting. Accordingly, the
consideration to be paid in the Merger will be allocated to assets acquired and
liabilities assumed based on their estimated fair values at the Effective Date.
Income (or loss) of Coast prior to the Effective Date will not be included in
income of the combined company. See "The Merger--Accounting Treatment."

        DISSENTERS' RIGHTS.

        Any holder of record of shares of Coast Common Stock who does not vote
in favor of the Transaction Proposal, delivers a demand for appraisal prior to
the vote of the Coast stockholders on the Transaction Proposal and complies with
the additional procedures required under Delaware law will have the right to
obtain cash payment for the "fair value" of such stockholders' shares (excluding
any element of value arising from the accomplishment or expectation of the
Merger). In order to exercise such rights, a stockholder must comply with all
the procedural requirements of Section 262 of the DGCL, the full text of which
is attached as Appendix E to this Proxy Statement/Prospectus. Section 262 should
be read in its entirety. Any such dissenting stockholder will not be entitled to
the Merger Consideration in respect of such shares unless and until such
dissenting stockholder shall have failed to perfect or shall have timely
withdrawn such dissenting stockholder's right to dissent from the Merger, and
shall instead be entitled to receive the payment provided by Section 262 of the
DGCL. FAILURE TO TAKE ANY OF THE STEPS REQUIRED UNDER SECTION 262 IN A TIMELY
MANNER WILL RESULT IN A LOSS OF APPRAISAL RIGHTS. See "Appraisal Rights."

        In connection with any appraisal proceeding, the "fair value" of shares
of Coast Common Stock is to be determined as of immediately prior to the CPR
Certificate Distribution and the Merger. Each CPR Certificate distributed to
each Coast stockholder will provide that it shall automatically be redeemed for
$0.01 in cash immediately following the Merger if the holder of the share as to
which such CPR Certificate was issued has given notice of an intent to exercise
appraisal rights. If any Coast stockholder who gives notice of intent to
exercise appraisal rights subsequently withdraws, or fails to perfect, such
appraisal demand, Ahmanson will deliver to such holder the number of CPR
Certificates equal to the number of shares of Coast Common Stock as to which
such appraisal demand was withdrawn or not perfected.




                                      -12-
<PAGE>   20

        It is a condition to the obligation of Ahmanson to consummate the Merger
that holders of no more than 5% of the outstanding shares of Coast Common Stock
shall have given notice that their shares of Coast Common Stock be treated as
Dissenters' Shares. See "The Merger--Conditions to Consummation."

        RESALES OF AHMANSON COMMON STOCK.

        The Ahmanson Common Stock issuable in connection with the Merger will be
freely transferable by the holders of such shares, except for those holders who
may be deemed to be "affiliates" (generally including directors, certain
executive officers and 10% or more stockholders) of Coast or Ahmanson under
applicable federal securities laws. See "The Merger--Resales of Ahmanson Common
Stock."

COMPARISON OF CERTAIN UNAUDITED PER SHARE DATA

        The following summary presents selected comparative unaudited per share
data for Ahmanson and Coast on an historical basis and on a pro forma combined
basis assuming the Merger had been effective during the periods presented. The
Merger will be accounted for under the purchase accounting method. The pro forma
data have been derived accordingly. The information shown below should be read
in conjunction with the historical financial data and statements of Ahmanson and
Coast incorporated by reference herein, including the respective notes thereto.
See "Available Information," "Incorporation of Certain Information by
Reference," "--Selected Consolidated Financial Data of Ahmanson (Historical),"
"--Selected Consolidated Financial Data of Coast (Historical)" and "The
Merger--Accounting Treatment."

        The per share data set forth herein are presented for comparative
purposes only and are not necessarily indicative of the future combined
financial position, the results of the future operations or the actual results
or combined financial position of Ahmanson and Coast that would have been
achieved had the Merger been consummated as of the dates or at the beginning of
the periods indicated. While no assurance can be given, Ahmanson expects that it
will achieve substantial benefits from the Merger, including operating cost
savings and revenue enhancements. See "Ahmanson and Coast Unaudited Pro Forma
Combined Financial Information."

However, the pro forma comparative unaudited per share data do not reflect any
direct costs, potential savings or revenue enhancements which Ahmanson expects
will result from the consolidation of operations of Coast and Ahmanson and,
therefore, do not purport to be indicative of the results of future operations
of Ahmanson.

(1)  Income per common share for both Ahmanson and Coast in 1996 was
     significantly affected by a special assessment in the third quarter to
     recapitalize the Savings Association Insurance Fund which was mandated by
     federal legislation.
(2)  Pro forma dividends per share represent historical dividends paid by
     Ahmanson. For a discussion of Ahmanson's current and future dividend
     policy, see "Comparative Market Prices and Dividends--Ahmanson."
(3)  Amount is calculated by dividing total pro forma common stockholders'
     equity by the sum of the total outstanding shares of Ahmanson Common Stock
     plus the new shares of Ahmanson Common Stock to be issued in the Merger
     (based on the number of shares of Coast Common Stock outstanding at
     September 30, 1997, excluding shares beneficially owned by Ahmanson and the
     Exchange Ratio of 0.8082).
(4)  Equivalent Coast pro forma combined amounts are computed by multiplying the
     pro forma combined amounts by the Exchange Ratio of 0.8082.

                               GENERAL INFORMATION

SPECIAL MEETING

        This Proxy Statement/Prospectus is being furnished to the stockholders
of Coast in connection with the solicitation of proxies by the Coast Board for
use at the Special Meeting. The Special Meeting will be held at ____ a.m., on
__________, 199_, and at any adjournments and postponements thereof, to consider
and vote upon the approval and adoption of the Transaction Proposal, consisting
of the Merger Agreement and the transactions contemplated thereby, including the
approval of the Merger, the establishment of and the terms of the CPR Trust, the
CPR Certificate Distribution, the engagement of the Litigation Trustees
(including the terms of their engagement) for the CPR Trust, the terms of the
Commitment and the rights of the holders of CPR Certificates.

        AHMANSON PROSPECTUS.

        This Proxy Statement/Prospectus is also being furnished by Ahmanson as a
prospectus in respect of the shares of Ahmanson Common Stock to be issued to
stockholders of Coast in connection with the Merger and, following consummation
of the Merger, in respect of any shares of Ahmanson Common Stock that are
issuable upon exercise of the Coast Stock Options that were outstanding as of
the Effective Date and replaced with options to acquire shares of Ahmanson
Common Stock ("Replacement Options"). Based on the [ ] shares of Coast Common
Stock outstanding on the Record Date, the [ ] shares of Coast Common Stock
issuable upon exercise of outstanding stock options and assuming the exercise of
all such stock options prior to the Effective Time and the Exchange Ratio of
0.8082, up to approximately [ ] Ahmanson Common Shares will be issuable upon
consummation of the Merger.

RECORD DATE, SOLICITATION AND REVOCABILITY OF PROXIES

        The Coast Board has fixed the close of business on _________ __, 1997,
as the record date for determining the Coast stockholders entitled to receive
notice of and to vote at the Special Meeting. Only holders of record of Coast
Common Stock as of the Record Date are entitled to notice of and to vote at the
Special Meeting. As of the Record Date, _______ shares of Coast Common Stock
were issued and outstanding and held by [___] record holders. Holders of Coast
Common Stock are entitled to one vote on each matter considered and voted on at
the Special Meeting for each share of Coast Common Stock held of record at the
close of business on the Record Date. The presence, in person or by properly
executed proxy, of the holders of a majority of the shares of Coast Common Stock
entitled to vote at the Special Meeting is necessary to constitute a quorum at
the Special Meeting. For purposes of determining the presence of a quorum,
abstentions will be counted as shares present but shares represented by a proxy
from a broker or nominee indicating that such person has not received
instructions from the beneficial owner or other person entitled to vote shares
("broker non-votes") will not be counted as shares present.

        Proxies in the form accompanying this Proxy Statement/Prospectus are
being solicited by the Coast Board. Shares of Coast Common Stock represented by
properly executed proxies that have not been revoked will be voted in accordance
with the instructions indicated on the proxies. If no instructions are
indicated, such proxies will be voted "FOR" approval of the Transaction
Proposal, and as determined by the proxies named therein to any other matter
that may come before the Special Meeting or any adjournment or postponement
thereof including, among other things, a motion to adjourn or postpone the
Special Meeting to another time and/or place, for the purpose of soliciting
additional proxies or otherwise; provided, however, that no proxy which is voted
against the proposal to approve the Merger Agreement will be voted in favor of
any such adjournment or postponement for the purpose of soliciting additional
proxies.

        A Coast stockholder who has given a proxy may revoke it at any time
prior to its exercise at the Special Meeting by (a) giving written notice of
revocation to the Secretary of Coast, (b) properly submitting to Coast a duly
executed proxy bearing a later date or (c) voting in person at the Special
Meeting. All written notices of revocation and other communications with respect
to revocation of proxies should be addressed to Coast as follows: 1000 Wilshire
Boulevard, Los Angeles, California 90017, Attention: Secretary (Telephone: (213)
362-2000). A proxy appointment will not be revoked by death or supervening
incapacity of the stockholder executing the proxy unless, before the shares are
voted,




                                      -21-
<PAGE>   29

notice of such death or incapacity is filed with Coast's Secretary or other
person responsible for tabulating votes on behalf of Coast.

        The expense of soliciting proxies for the Special Meeting will be paid
for by Coast, although pursuant to the Merger Agreement, Ahmanson has agreed to
share equally with Coast all filing fees and printing expenses payable in
connection with the Registration Statement[s] and this Proxy
Statement/Prospectus. In addition to the solicitation of stockholders of record
by mail, telephone or personal contact, Coast will be contacting brokers,
dealers, banks and voting trustees or their nominees who can be identified as
record holders of Coast Common Stock; such holders, after inquiry by Coast, will
provide information concerning the quantity of proxy and other materials needed
to supply such materials to beneficial owners, and Coast will reimburse them for
the expense of mailing the proxy materials to such persons.

        Coast has retained ______________________ ("______") to assist Coast in
connection with its communications with its stockholders with respect to, and to
provide other services to Coast in connection with, the Special Meeting.
________________ will receive a fee of $_____ for its services and reimbursement
of out-of-pocket expenses in connection therewith. Coast has agreed to indemnify
______ against certain liabilities arising out of or in connection with its
engagement.

VOTE REQUIRED

        Approval of the Transaction Proposal requires the affirmative vote of
the holders of a majority of the outstanding shares of Coast Common Stock. A
vote of the stockholders of Ahmanson is not required under the DGCL or the rules
of the NYSE for approval of the Merger Agreement or consummation of the
transactions contemplated thereby.

        As of the Record Date, Coast directors and executive officers and their
affiliates held approximately ____% of the outstanding shares of Coast Common
Stock entitled to vote at the Special Meeting. Such persons have indicated to
Coast that they intend to vote in favor of the Transaction Proposal. As of the
Record Date, Ahmanson held ___ shares of Coast Common Stock and directors and
executive officers of Ahmanson and their affiliates held [no] [______] shares of
Coast Common Stock. See "The Merger--Interests of Certain Persons in the
Transaction Proposal."

RECOMMENDATION OF COAST BOARD OF DIRECTORS

        For the reasons described in the section of this Proxy
Statement/Prospectus entitled "The Merger--Reasons of Coast for the Merger," the
Coast Board has unanimously approved the Transaction Proposal and adopted the
Merger Agreement. The Coast Board believes that approval of the Transaction
Proposal, consisting of the Merger Agreement and the transactions contemplated
thereby, including the approval of the Merger, the establishment of and the
terms of the CPR Trust, the CPR Certificate Distribution, the engagement of the
Litigation Trustees (including the terms of their engagement) for the CPR Trust,
the terms of the Commitment and the rights of the holders of CPR Certificates,
is in the best interests of Coast and its stockholders and unanimously
recommends that the stockholders of Coast vote "FOR" approval of the Transaction
Proposal. As a result of the difficulty in establishing the value of the
Litigation for purposes of the Merger, the Coast Board determined that the
ultimate value of the Litigation should be retained by Coast's stockholders in
connection with the Merger and, thus, the Coast Board, as an integral part of
its approval of the Transaction Proposal, approved the establishment of the CPR
Trust, the terms of the CPR Certificates and the Commitment, the CPR Certificate
Distribution and related matters. See "The Merger--Background of the Merger,"
"--Reasons of Coast for the Merger" and "--Interests of Certain Persons in the
Transaction Proposal."

                                   THE MERGER

        The following information describes certain information pertaining to
the Merger and the other transactions contemplated by the Merger Agreement. This
description does not purport to be complete and is qualified in its entirety by
reference to the Appendices hereto, including the Merger Agreement and the form
of Commitment, which are attached as Appendices A and C hereto, respectively,
and are incorporated herein by reference. All stockholders are urged to read the
Appendices in their entirety.

GENERAL

        The Merger Agreement provides for a transaction in which Coast will
merge with and into Ahmanson. Ahmanson will be the surviving corporation of the
Merger. If the Transaction Proposal is approved at the Special Meeting, all
required governmental and other consents and approvals are obtained and all of
the other conditions to the obligations of the parties to consummate the Merger
are either satisfied or waived (if permitted), the CPR Distribution will be
effected and, immediately thereafter, the Merger will be consummated. A copy of
the Merger Agreement is set forth as Appendix A to this Proxy
Statement/Prospectus.

MERGER CONSIDERATION; EXCHANGE RATIO; COMMITMENT

        MERGER CONSIDERATION; EXCHANGE RATIO.

        The Merger Consideration pursuant to the Merger Agreement consists of
(a) the shares of Ahmanson Common Stock issuable in exchange for the outstanding
shares of Coast Common Stock pursuant to the Merger Agreement, and cash in lieu
of fractional share interests, and (b) the entering into of the Commitment by
Ahmanson. At the Effective Time, each share of issued and outstanding Coast
Common Stock, together with each associated Coast Right, will cease to be
outstanding and each such share (other than (i) certain shares, if any, held by
Coast, Ahmanson or their subsidiaries and (ii) Dissenters' Shares, if any) will
be converted into and exchanged for 0.8082 of a share of Ahmanson Common Stock
(with the appropriate number of Ahmanson Rights as provided in the Ahmanson
Rights Plan). In addition, Ahmanson will enter into the Commitment with the CPR
Trust at or prior to the Effective Time and effective at the Effective Time.

        COMMITMENT.

        Ahmanson will enter into the Commitment, substantially in the form
attached hereto as Appendix C, with the CPR Trust at or prior to the Effective
Time and effective at the Effective Time. The Commitment will obligate Ahmanson
to pay to the CPR Trust from time to time an aggregate amount equal to the
Commitment Amount. As used in this Proxy Statement/Prospectus, the Commitment
Amount means the Litigation Proceeds minus the Reimbursements plus the Assumed
Tax Benefit. Litigation Proceeds means any and all cash payments (the "Cash
Proceeds") actually received by the Ahmanson Group pursuant to a final,
non-appealable judgment or a final settlement of the Litigation and the non-cash
payments (the "Non-Cash Proceeds"), if any, actually received by the Ahmanson
Group pursuant to a final, non-appealable judgment or a final settlement of the
Litigation. Reimbursements means (a) an amount equal to the Expense Fund plus
(b) interest on the portions of the Expense Fund withdrawn by the CPR Trust
calculated from the time of any such withdrawal at an annual interest rate equal
to the Reference Rate in effect from time to time plus 250 basis points,
compounded quarterly plus (c) the Assumed Tax Liability plus (d) in the event
Litigation Proceeds are required to be included in income for federal income tax
purposes in a taxable year prior to the year such proceeds are received in cash
(either because of the accrual of Cash Proceeds before the payment thereof or
the time required to liquidate Non- Cash Proceeds), interest at the Reference
Rate plus 250 basis points from the date of such payment of taxes to the date of
receipt of cash. The Expense Fund means an amount equal to $20 million, less the
expenses relating to the Litigation incurred and paid between August 31, 1997
and the Effective Date, which amount Ahmanson will deposit at the Effective Time
in a non-interest bearing demand-deposit account in the name of the CPR Trust at
Home Savings.

<PAGE>   31

          ASSUMED TAX LIABILITY; ASSUMED TAX BENEFIT; TAX ASSUMPTIONS.

        Pursuant to the Commitment, regardless of any position taken by the
Ahmanson Group on any tax return or in any claim for refund with respect to the
receipt of the Litigation Proceeds or payments on the Commitment (or of the
actual payment or actual receipt of any taxes with respect thereto), the Assumed
Tax Liability will, (i) if there is no Determination, be computed based on the
Tax Assumptions and (ii) if there is a Determination to the effect that
Litigation Proceeds are not includible in gross income in whole or in part, be
computed on the basis of the Tax Assumptions as such Tax Assumptions are
modified by such Determination. In addition, pursuant to the Commitment,
regardless of any position taken by the Ahmanson Group on any tax return or in
any claim for refund with respect to the receipt of the Litigation Proceeds or
payments on the Commitment (or of the actual payment or actual receipt of any
taxes with respect thereto), the Assumed Tax Benefit will, (i) if there is no
Determination, be computed based on the Tax Assumptions and (ii) if there is a
Determination that no deduction is allowed (or that any allowed deduction is
limited) with respect to the application of Section 483(a) to payments of the
Commitment Amount, be computed on the basis of the Tax Assumptions as such Tax
Assumptions are modified by such Determination.

        As used herein, the "Assumed Tax Liability" means an amount equal to the
income (including franchise) tax liability of the Ahmanson Group (not including
any deduction attributable to Section 483(a) of the Code) attributable to the
receipt of the Litigation Proceeds computed in the manner set forth above. As
used herein, the "Assumed Tax Benefit" means an amount equal to the deduction
that would be allowed to the Ahmanson Group under Section 483(a) of the Code
computed in the manner set forth above.

        As used herein, the "Tax Assumptions" mean the following assumptions:

               (a) The Litigation Proceeds will be includible in gross income as
ordinary income in full.

               (b) Payments on the Commitment will not be deductible except that
        Section 483(a) will apply to payments on the Commitment, other than
        those allocable to CPR Certificates issued on exercise of employee
        options or otherwise in a transaction that is not a sale or exchange,
        and payments of the Commitment Amount will be deductible to the extent
        treated by Section 483(a) as interest expense; it being understood that
        it is not intended that the distribution of the CPR Certificates
        immediately prior to the Effective Time of the Merger will result in the
        characterization of such distribution as not constituting "a sale or
        exchange."

               (c) The income tax liability attributable to the assumed
        inclusion of all or a portion of the Litigation Proceeds in gross income
        as ordinary income and the benefit of any deduction assumed to be
        allowed under Section 483(a) will be (i) the product of the amount of
        such income or deduction and the highest statutory rate of federal
        income tax applicable to corporations for the year in which the income
        is assumed to be included or the deduction is assumed to be realized
        plus (ii) the product of such income or deduction and the net combined
        marginal rate of state and local income (or franchise) tax of the
        relevant member or members of the Ahmanson Group for the year in which
        the income is assumed to be included and the deduction is assumed to be
        realized, net of the federal income tax benefit (calculated based on the
        rate in clause (i)) of such state or local income (or franchise) tax.
        The relevant member or members of the Ahmanson Group will be the member
        or members that is or are assumed to include the Litigation Proceeds in
        income or is or are assumed to be allowed a deduction under Section
        483(a).

               (d) Any benefit from any deduction allowable to the Ahmanson
        Group under paragraph (c) of these Tax Assumptions for payments made on
        the Commitment will be assumed to be realized (i) when those payments
        are made to the extent those payments do not exceed the Litigation
        Proceeds included in income for the same taxable year, or (ii) otherwise
        when, taking into account other deductions or losses or credits of the
        Ahmanson Group, the deduction would reduce the tax otherwise payable or
        result in a refund of tax already paid.

               (e) Ahmanson will be entitled to rely on a written opinion of
        either Sullivan & Cromwell or another nationally recognized law firm
        with expertise on the matter on which the opinion is sought (with a copy




                                      -24-
<PAGE>   32

        of such opinion to the Litigation Trustees) that is selected by Ahmanson
        and (unless such law firm is principal outside tax counsel to Ahmanson)
        reasonably acceptable to the Litigation Trustees in determining whether
        there has been a Determination and in otherwise applying the Tax
        Assumptions to determine the income (including franchise) tax liability
        of the Ahmanson Group attributable to the receipt of the Litigation
        Proceeds and payments of the Commitment Amount and any tax benefit
        attributable to payments on the Commitment Amount.

               (f) If the Assumed Tax Liability or the Assumed Tax Benefit
        cannot be computed at the time of the receipt of the Cash Proceeds or a
        payment on the Commitment because of the absence of information as to
        tax rates and other factors described in the definition of Assumed Tax
        Liability or the definition of Assumed Tax Benefit, as the case may be,
        the Ahmanson Group will compute a tentative Assumed Tax Liability or a
        tentative Assumed Tax Benefit, as the case may be, based on such
        assumptions that in the reasonable opinion of the Ahmanson Group would
        protect the Ahmanson Group against any risk of loss. The payment of the
        Commitment Amount will be based on such tentative Assumed Tax Liability
        or such tentative Assumed Tax Benefit computation, as the case may be.
        As soon as feasible, but in no event later than 12 months after the end
        of the taxable year in which the Commitment Amount is paid, the Ahmanson
        Group will recompute the Assumed Tax Liability or the Assumed Tax
        Benefit, as the case may be, and pay to the CPR Trust any excess of the
        re-computed Commitment Amount over the Commitment Amount that was
        initially calculated plus interest for the period over which the payment
        was deferred at a rate of Home Savings' cost of funds as submitted
        monthly to the Federal Home Loan Bank of San Francisco.

        Under the Commitment, a Determination that Litigation Proceeds are not
includible in gross income in whole or in part will be deemed to be made on the
earlier of (a) the date a final judicial determination to such effect, binding
upon Ahmanson, is made in the Litigation, (b) the date a final agreement to
which Ahmanson is a party with the federal government to such effect is entered
into at the direction of the Litigation Trustees as part of the resolution of
the Litigation or a related Internal Revenue Service ("IRS") ruling to such
effect issued to a member of the Ahmanson Group in connection with such
agreement (it being understood that the Ahmanson Group will be under no
obligation to seek such a ruling or refund or enter into such an agreement;
provided that if requested the Ahmanson Group will enter into such an agreement
if such agreement does not impose any liability or obligation whatsoever (other
than a standard settlement release relating only to the Litigation or other
related claims that Coast or Coast Federal or Coast's stockholders might have
been able to bring as of immediately prior to the Merger) on the Ahmanson Group
or adversely affect or restrict the conduct of its business or adversely affect
its tax posture with respect to other matters) and (iii) the effective date of a
law, regulation or IRS ruling to such effect that applies to Ahmanson or
taxpayers generally, and would be applicable to claims against the federal
government arising out of capital credits affected by Financial Institutions
Reform, Recovery and Enforcement Act of 1989 ("FIRREA"). Notwithstanding the
foregoing, no such Determination will be deemed to be made unless it is made
prior to the earlier of (x) thirty days before the date of filing by the
Ahmanson Group of the federal tax return for the taxable year in which the
Litigation Proceeds are assumed to be includible in gross income or (y) the
receipt by the Ahmanson Group of the Litigation Proceeds.

        Under the Commitment, a Determination with respect to the application of
Section 483(a) to payments of the Commitment Amount will be deemed to be made on
the earlier of (i) the date a final judicial determination to such effect
binding upon Ahmanson is made in the Litigation, (ii) the date a final agreement
to which Ahmanson is a party with the federal government to such effect is
entered into at the direction of the Litigation Trustees as part of the
resolution of the Litigation or a related IRS ruling to such effect issued to a
member of the Ahmanson Group in connection with such agreement (it being
understood that the Ahmanson Group will be under no obligation to seek such a
ruling or refund or enter into such an agreement; provided that if requested the
Ahmanson Group will enter into such an agreement if such agreement does not
impose any liability or obligation whatsoever (other than a standard settlement
release relating only to the Litigation or other related claims that Coast or
Coast Federal or Coast's stockholders might have been able to bring as of
immediately prior to the Merger) on the Ahmanson Group or adversely affect or
restrict the conduct of its business or adversely affect its tax posture with
respect to other matters) and (iii) the effective date of a law, regulation or
IRS ruling or a judicial decision to such effect that applies to Ahmanson or
taxpayers generally. A deduction shall be considered allowed under Section
483(a) to the extent that a deduction is allowed, in an amount up to the
deduction calculated under Section 483(a), under another substantially
equivalent provision.




                                      -25-

        Ahmanson will have no obligation to take or to refrain from taking any
action that would or could reduce the income tax liability of the Ahmanson Group
in respect of the Litigation Proceeds or obtain income tax benefits in respect
thereof on related payments.

        PAYMENT PROCEDURES WITH RESPECT TO THE COMMITMENT AMOUNT.

          Pursuant to the Commitment, within 10 days of the receipt by the
Ahmanson Group of the Litigation Proceeds, Ahmanson will deliver to the
Litigation Trustees a written notice (the "Proceeds Notice") specifying that the
Litigation Proceeds have been received and describing the type and amount of any
Non-Cash Proceeds received. Within 10 days of the delivery of the Proceeds
Notice, the Litigation Trustees will deliver to Ahmanson written instructions to
liquidate the Non-Cash Proceeds received. If so instructed, Ahmanson will then
liquidate the Non-Cash Proceeds in accordance with the instructions. As promptly
as practicable but in no event later than 30 days after the later of the receipt
by Ahmanson of the Litigation Proceeds and the liquidation by Ahmanson of
Non-Cash Proceeds, Ahmanson will deliver to the Litigation Trustees a
certificate (the "Ahmanson Certificate") setting forth the calculation of the
Commitment Amount, which Ahmanson Certificate will be valid and binding absent
manifest error. The Ahmanson Certificate will set forth each of the items
required under the Commitment to calculate the Commitment Amount, including the
amount of Litigation Proceeds and the amount of (and calculation of) each
component of the Reimbursements and the assumptions underlying the determination
of each item, and Ahmanson will attach to the Ahmanson Certificate financial and
other documentation reasonably sufficient to support each item and assumption
used to calculate the Commitment Amount. Notwithstanding the foregoing, with
respect to the combined marginal rate of state and local income (or franchise)
tax of the relevant member or members of the Ahmanson Group, for the purposes of
the calculation contained in the Ahmanson Certificate, Ahmanson will be entitled
to assume the most conservative rate reasonably possible. Within 15 days of
delivery of the Ahmanson Certificate, the CPR Trust will give written notice
specifying whether it agrees or objects to the calculation of the Commitment
Amount in the Ahmanson Certificate. If the CPR Trust delivers a written notice
to the effect that it agrees with the calculation, Ahmanson will then deliver
the Commitment Amount to the institutional trustee for the CPR Trust within 5
business days of such written notice. If the CPR Trust delivers a written notice
to the effect that it objects to the calculation, Ahmanson will deliver the
Commitment Amount only upon a Resolution.

        If the CPR Trust delivers a written notice to the effect that it objects
to the calculation, the CPR Trust will simultaneously deliver to Ahmanson a
certificate (the "CPR Calculation Certificate") setting forth its calculation of
the Commitment Amount. The CPR Calculation Certificate will set forth each of
the items required under the Commitment to calculate the Commitment Amount,
including the amount of Litigation Proceeds and the amount of (and calculation
of) each component of the Reimbursements and the assumptions underlying the
determination of each item, and the CPR Trust will attach to the CPR Calculation
Certificate financial and other documentation reasonably sufficient to support
each item and assumption used to calculate the Commitment Amount. If Ahmanson
does not agree with the CPR Trust's calculation of the Commitment Amount, then
within 10 business days of the delivery by the CPR Trust of the CPR Calculation
Certificate, Ahmanson and the CPR Trust will submit the calculation of the
Commitment Amount to a mutually agreed upon independent certified public
accountant (the "Accountant"). If Ahmanson and the CPR Trust cannot agree upon
such independent certified public accountant, then the Commitment will provide
that the Accountant will be [__________]. The Accountant will be instructed to
determine whether the calculation set forth in the Ahmanson Certificate
contained manifest error and the Accountant will be instructed to conclude that
the calculation set forth in the Ahmanson Certificate does not contain manifest
error so long as the calculation is a reasonable calculation of the Commitment
Amount based upon a reasonable interpretation of the provisions of the
Commitment. If the Accountant determines (a) that the calculation set forth in
the Ahmanson Certificate did not contain manifest error, the Commitment Amount
will be as calculated in the Ahmanson Certificate or (b) that the calculation
set forth in the Ahmanson Certificate did contain manifest error, the Accountant
will recompute the Commitment Amount based upon the formulae and definitions set
forth in the Commitment and described herein and the Accountant's calculation
will be binding on both Ahmanson and Coast (in either of case (a) or (b), a
"Resolution"). In the event it is determined that Ahmanson's calculation
contained manifest error, in addition to the Commitment Amount, Ahmanson will
pay to the CPR Trust interest on the Commitment Amount calculated from the date
that the CPR Trust delivered its written notice of objection at an annual
interest rate equal to the Reference Rate plus 250 basis points.




                                      -26-
<PAGE>   34

        DUE DATE

        Pursuant to the Commitment, Ahmanson will pay to the CPR Trust the
Commitment Amount (a) if the CPR Trust does not object to the calculation set
forth in the Certificate, within 5 business days of written notice from the CPR
Trust to the effect that it agrees with the calculation or (b) if the CPR Trust
does object to the calculation set forth in the Certificate, within 5 business
days of the Resolution (each, a "Due Date"). If Ahmanson does not pay the
Commitment Amount by the appropriate Due Date, Ahmanson will be obligated to pay
to the CPR Trust the Commitment Amount plus interest on the Commitment Amount
from the Due Date until the date the Commitment Amount is paid, calculated at an
annual interest rate equal to the Reference Rate plus 250 basis points.

        Notwithstanding the foregoing, Ahmanson will not be obligated to pay the
Commitment Amount or any portion thereof at the Due Date and will be deemed not
to be in default of the Commitment and not to have violated its obligations
thereunder by virtue of not having paid the Commitment Amount or such portion
thereof (a) to the extent that Home Savings is not permitted due to regulatory
restrictions to distribute to Ahmanson the Litigation Proceeds and (b) if prior
to the Due Date, Ahmanson has delivered to the CPR Trust a certificate (an
"Officer's Certificate") from the [chief financial officer] of Home Savings
specifying that portion of the Litigation Proceeds that cannot be paid due to
regulatory restrictions and the applicable law, regulation or other action of a
regulatory authority that is the source of the regulatory restrictions
preventing the distribution by Home Savings [and an opinion of counsel, which
may be from a member of Ahmanson's internal legal department, substantially to
the effect that the distribution by Home Savings of the Litigation Proceeds or
the applicable portion thereof, as the case may be, would result in the
violation of the applicable law, regulation or other action of a regulatory
authority that is the source of the regulatory restrictions preventing the
distribution by Home Savings (an "Opinion of Counsel")]. [Under the Commitment,
Ahmanson will be entitled not to pay the Commitment Amount or any portion
thereof as specified in the immediately preceding sentence with the consequences
specified in the immediately preceding sentence for a period of [ ] years from
the Due Date on which the Commitment Amount or such portion thereof would
otherwise have been payable so long as (i) Home Savings continues not to be
permitted to distribute such portion of the Litigation Proceeds to Ahmanson due
to regulatory restrictions and (ii) Ahmanson delivers on a quarterly basis
beginning with the first full fiscal quarter following the Due Date an Officer's
Certificate [and an Opinion of Counsel]].

        AHMANSON LITIGATION.

        Ahmanson also has litigation pending against the U.S. government
involving the regulatory capital treatment of certain supervisory goodwill,
which claims are similar to the Litigation. Ahmanson intends to pursue that
litigation solely in the best interests of its stockholders and without regard
to any possible impact on the Litigation or the value of the CPR Certificates.

        NO AHMANSON RESPONSIBILITY FOR THE LITIGATION.

        The Litigation will remain an asset of Coast Federal and its successors.
As provided in the CPR Trust Agreement, the Litigation will be solely under the
control of the Litigation Trustees and Ahmanson will not participate in or have
any responsibility for any decisions regarding the administration of the
Litigation. The terms of the CPR Trust Agreement and the Commitment explicitly
provide that the holders of the CPR Certificates and the Litigation Trustees
shall have no rights to enforce, institute or maintain any suit, action or
proceeding against Ahmanson, Home Savings, its affiliates, officers, directors,
employees or agents relating to the formation of the CPR Trust, the entering
into of the Commitment, the distribution of the CPR Certificates, the Litigation
or the performance by the Litigation Trustees of their duties as Litigation
Trustees, except that the CPR Trust (or the Litigation Trustees on behalf of the
CPR Trust) may enforce, institute or maintain a suit, action or proceeding
against Ahmanson for breach of the Commitment or failure to deliver any CPR
Certificate when due or return to the CPR Trust for cancellation any CPR
Certificate required to be returned or against Ahmanson for failure to deposit
the Expense Fund at the Effective Time or against Home Savings for breach of any
depository relationship obligations it may have with respect to the Expense Fund
(and except to the extent that Ahmanson and Home Savings succeed to the
obligations of Coast and Coast Federal, respectively, under the CPR Trust
Agreement).




                                      -27-
<PAGE>   35

        The Commitment will provide that except as expressly set forth in the
Commitment (or in any other documents to which Ahmanson has succeeded as a
matter of law), Ahmanson will have no other obligations to the CPR Trust, the
Litigation Trustees or the holders of CPR Certificates. Without limiting the
generality of the foregoing and except as provided in the Merger Agreement,
Ahmanson will have no obligation to advance funds to the CPR Trust, the
Litigation Trustees or the holders of CPR Certificates.

BACKGROUND OF THE MERGER

        The Coast Board and the management of Coast have recognized that in
order to remain competitive in the consolidating financial services industry, it
is essential to provide a broader array of consumer and business banking
products, to achieve economies of scale and to continue Coast's expansion of the
variety of products that it offers to customers. In an effort to address these
concerns, from time to time in the last year, Coast and its financial advisors
have had conversations with other financial institutions regarding possible
merger scenarios, and the Coast Board has discussed certain of these
possibilities, with the assistance of Goldman Sachs and outside counsel.

        Also in the last year, the Coast Board and management discussed the
possibility of issuing securities relating to the Litigation to the Coast
stockholders, either in connection with a merger or in the absence of a merger.

        In late August 1997, Ray Martin, Chairman and Chief Executive Officer of
Coast, arranged an informal meeting with Charles R. Rinehart, Chairman and Chief
Executive Officer of Ahmanson. Prior to this meeting, at Ahmanson's request
Goldman Sachs provided Ahmanson with certain publicly available financial
information. Robert L. Hunt II, Coast's Chief Operating Officer, and Kevin
Twomey, Ahmanson's Chief Financial Officer, also attended this meeting, during
which the parties discussed a possible business combination between Coast and
Ahmanson. Over the course of subsequent informal meetings, Mr. Martin, Mr. Hunt,
Mr. Twomey and selected officers of Coast and Ahmanson discussed the structure
of a potential merger, including Coast's desire to preserve the potential value
of the Litigation for the benefit of Coast stockholders, and Ahmanson's
agreement to that approach so that it did not have to value or pay Coast
stockholders for the Litigation.

        During early September, Mr. Martin and Mr. Rinehart negotiated the
principal business terms of the Merger. On September 17, 1997, they reached
tentative agreement on the exchange ratio, subject to agreement on satisfactory
arrangements with respect to securities relating to the Litigation to be issued
to Coast stockholders, satisfactory completion of due diligence reviews of the
business and assets of the respective companies and approvals by the Coast Board
and Ahmanson's Board of Directors (the "Ahmanson Board"). The contemplated
exchange ratio was 0.81 of a share of Ahmanson Common Stock for each share of
Coast Common Stock, assuming that the closing price of Ahmanson Common Stock was
$57.00 or less on the last trading day immediately preceding execution of a
Merger Agreement. If the price of a share of Ahmanson Common Stock at that time
was in excess of $57.00, the proposed exchange ratio would be reduced so that
each share of Coast Common Stock would be exchanged for the number of shares of
Ahmanson Common Stock as would then have a market value of approximately $46.17.
In addition, it was contemplated that Coast stockholders would receive
securities relating, in the aggregate, to 100% of the net after-tax value of any
damage award in or settlement of the Litigation.

        On September 18, 1997, Coast and Ahmanson entered into a customary
confidentiality agreement containing a "standstill" provision pursuant to which
each party agreed, for a period of two years following the date of such
agreement, not to take certain actions relating to an acquisition of the other
party's assets or securities without such other party's consent. Following the
execution and delivery of the confidentiality agreement, each of Coast and
Ahmanson began its due diligence review of the other.

        In preparation for a September 19, 1997 meeting of the Coast Board to
discuss the status of discussions with Ahmanson, and in view of the retention of
special mergers and acquisition counsel to advise Coast and the Coast Board as
an entirety, at the request of several non-management directors Coast's regular
outside counsel was designated to meet separately with the non-management
directors. At the September 19, 1997 special telephonic meeting of the Coast
Board, Mr. Martin described the status of discussions between the parties.
Coast's senior management and Goldman Sachs discussed the reasons for the Merger
and the potential benefits to Coast and its stockholders from the Merger, and
also




                                      -28-
<PAGE>   36

discussed the strategic and business rationale and financial aspects of the
Merger. Coast's special merger and acquisitions counsel reviewed the directors'
obligations in connection with the possible Merger with the entire Coast Board
and Coast's regular outside counsel reviewed such obligations separately with
the non-management directors.

        At a September 21, 1997 special meeting of the Coast Board, the Coast
Board was provided with additional details regarding the history and status of
the discussions with Ahmanson. At that meeting, Goldman Sachs made a
presentation regarding the proposed financial terms of the Merger and Coast's
legal advisors described, and the Coast Board discussed, the terms of the draft
Merger Agreement that had been proposed by Ahmanson and the potential terms of
the securities relating to the Litigation. In addition, the Coast Board
evaluated with management, Goldman Sachs and counsel Coast's strategic
alternatives to the Merger, including the possibility of (i) seeking to merge
with some other banking organization, (ii) remaining independent and seeking to
merge with Ahmanson or another banking organization at a later date and (iii)
remaining independent indefinitely. The Coast Board also discussed with
management, counsel and Goldman Sachs the factors discussed below under
"--Reasons of Coast for the Merger," and the non-management directors discussed
separately with counsel the selection, role and compensation of the Litigation
Trustees.

        During the period from September 18, 1997 to the meeting of the Coast
Board on October 5, 1997, the Merger Agreement and the terms of the CPR
Certificates were drafted, discussed and negotiated by Coast, Ahmanson and their
respective representatives.

        During meetings between Coast, Ahmanson and their counsel on Friday,
October 3, 1997, all material issues with respect to the Merger Agreement
(including the terms of the CPR Certificates) were resolved. In view of the fact
that the closing price of Ahmanson Common Stock on October 3 was $57.125, the
Exchange Ratio was set at 0.8082 of a share of Ahmanson Common Stock for each
share of Coast Common Stock, representing a market value of $46.17 per share of
Coast Common Stock based on the October 3, 1997 closing price of Ahmanson Common
Stock.

        On October 5, 1997, the Ahmanson Board met and approved the Merger
Agreement and the transactions contemplated thereby. Later that day, at a
special meeting of the Coast Board with all members of the Coast Board present,
Mr. Martin and senior management of Coast again presented the reasons for and
the potential benefits of the Merger. Coast's legal advisors reviewed the terms
of the Merger Agreement, including the terms of the CPR Trust and the CPR
Certificates, and Goldman Sachs updated its presentation regarding the financial
terms of the Merger and rendered its opinion that the Consideration (as defined
in "--Opinion of Coast's Financial Advisor") is fair, from a financial point of
view, to holders of Coast Common Stock. See "--Opinion of Coast's Financial
Advisor." After discussion of the Merger Agreement and of the factors discussed
below under "--Reasons of Coast for the Merger," the Coast Board unanimously
approved and authorized the execution of the Merger Agreement and approved the
transactions contemplated thereby, including the Merger, the establishment of
and the terms of the CPR Trust, the CPR Certificate distribution, the engagement
of the Litigation Trustees (including the terms of their engagement), the terms
of Ahmanson's obligation to pay the Commitment Amount to the CPR Trust and the
rights of the holders of the CPR Certificates.

REASONS OF COAST FOR THE MERGER

        In determining to approve the Merger Agreement and the transactions
contemplated thereby and to recommend approval of the Transaction Proposal by
the Coast stockholders, the Coast Board reviewed and considered a number of
factors, including, without limitation, the following:

               (a) Certain Financial and Other Information Concerning Coast. The
        Coast Board took into account its familiarity with and review of the
        financial condition, results of operations, cash flow, earnings and
        business of Coast both on a historical and a prospective basis.

               (b) Advice of Financial Advisor and Fairness Opinion. The Coast
        Board considered the financial presentations of Goldman Sachs on
        September 21 and October 5, 1997, and the opinion of Goldman Sachs
        rendered to the Coast Board on October 5, 1997 that the Consideration is
        fair, from a financial point of view, to the holders of Coast Common
        Stock. See "--Opinion of Coast's Financial Advisor."




                                      -29-
<PAGE>   37

               (c) Economic Terms of the Merger. The Coast Board considered that
        the terms of the Merger are beneficial to Coast stockholders in that
        Coast stockholders will both (i) become stockholders of a combined
        institution that will be a leading financial institution in California
        and (ii) retain a 100% interest in an amount equal to the value of any
        proceeds (after expenses and taxes calculated according to certain
        assumptions) of the Litigation.

               (d) The CPR Certificates. The Coast Board took into account the
        terms of the CPR Certificates, including the fact that the CPR
        Certificates are expected to be freely tradable. In this regard, the
        Coast Board also took into account that although there can be no
        assurance as to the development of a market for the CPR Certificates,
        efforts will be made to list the CPR Certificates on the NASDAQ National
        Market System and that a reasonably liquid market appeared to exist for
        somewhat similar securities issued by California Federal Bank, A Federal
        Savings Bank, with similar claims against the federal government.

               (e) Other Terms of the Merger Agreement. The Coast Board
        considered the terms of the Merger Agreement, including the fact that
        the Coast Board's obligation under the Merger Agreement to recommend the
        Merger to the Coast stockholders and the Coast Board's obligations not
        to solicit, or to provide information or engage in discussions in
        connection with, other proposals to acquire Coast, are both subject to
        the Coast Board's fiduciary duties to the Coast stockholders in the
        event that the Coast Board were to conclude in good faith that another
        unsolicited acquisition proposal was superior to the Merger. The Coast
        Board also took into account that if the Merger Agreement were
        terminated under certain conditions and Coast or any of its subsidiaries
        then entered into a definitive agreement with respect to a merger or
        acquisition with a third party within 12 months of termination, Coast
        would be required to pay a $35 million termination fee to Ahmanson.

               (f) Certain Financial and Other Information Concerning Ahmanson.
        The Coast Board considered information regarding (i) the strategy,
        business, operations, earnings and financial condition of Ahmanson on
        both an historical and a prospective basis and (ii) the historical stock
        price performance of Ahmanson Common Stock, in each case based in part
        on presentations by Goldman Sachs at the September 21 and October 5,
        1997 meetings. See "--Opinion of Coast's Financial Advisor."

               (g) Opportunities for Efficiencies and Cost Savings. The Coast
        Board took into account that, although no assurances can be given, there
        were likely to be anticipated cost savings, operating efficiencies and
        synergies available to Ahmanson from the Merger and possible enhanced
        revenue opportunities.

               (h) Alternatives to the Merger Agreement. The Coast Board
        considered strategic alternatives to enhance stockholder value,
        including the possibility of (i) seeking to merge with some other
        banking organiza tion, (ii) remaining independent and seeking to merge
        with Ahmanson or another banking institution at a later date and (iii)
        remaining independent indefinitely.

               (i) Tax Treatment of the Transaction. The Coast Board took into
        account the anticipated tax treatment of the Merger. See "--Certain
        Federal Income Tax Consequences."

               (j) Regulatory Approvals. The Coast Board took into account its
        belief, after consultation with its legal counsel, that the regulatory
        approvals necessary to consummate the Merger could be obtained. See
        "--Regulatory Matters."

               (k) Economic and Competitive Environment. The Coast Board
        considered the operating environment for Coast, including, but not
        limited to, the continuing consolidation and increasing competition in
        the thrift, banking and financial services industries in California and
        nationally [and the prospect for further changes in these industries and
        the importance of operational scale and financial resources to remaining
        competitive in the long term].

               (l) Size and Competitiveness of Combined Company. The Coast Board
        took into account its assessment that the combined company resulting
        from the Merger might better serve the convenience and needs




                                      -30-
<PAGE>   38

        of its customers and the communities it serves as a result of being a
        substantially larger financial institution, thereby potentially
        affording access to greater financial, managerial and technological
        resources and an ability to offer an expanded range of products and
        services.

               (m) Due Diligence Review. The Coast Board considered the results
        of the due diligence investigations conducted by Coast management and
        its advisors, including, among other things, assessments of Ahmanson's
        credit policies, asset quality, adequacy of loan loss reserves and
        interest rate risk.

               (n) Impact on Coast's Constituencies. The Coast Board considered
        the general impact the Merger would have on the various constituencies
        served by Coast, including its employees. The Coast Board took into
        account the potential for a substantial number of Coast employees to
        retain their current positions or to obtain employment with Ahmanson.
        The Coast Board also took into account Ahmanson's favorable ratings
        under the Community Reinvestment Act.

        In reaching its determination to approve and recommend the Merger, the
Coast Board did not assign any relative or specific weights to the various
factors considered by it, and individual directors may have given differing
weights to different factors. The foregoing discussion of the information and
factors considered by the Coast Board is not intended to be exhaustive but is
believed to include all material factors considered by the Coast Board.

        BASED ON THE FOREGOING, THE COAST BOARD BELIEVES THAT THE MERGER IS IN
THE BEST INTEREST OF COAST AND ITS STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT
COAST STOCKHOLDERS VOTE "FOR" APPROVAL OF THE TRANSACTION PROPOSAL.

OPINION OF COAST'S FINANCIAL ADVISOR

        Goldman Sachs was retained by Coast to act as its financial advisor in
connection with the Merger and to render an opinion as to the fairness from a
financial point of view of the consideration to be received by Coast or its
stockholders pursuant to the Merger. At meetings of the Coast Board held on
September 21, 1997 and October 5, 1997, Goldman Sachs made presentations on
financial aspects of the Merger and at the October 5, 1997 meeting delivered to
the Coast Board its written opinion dated as of such date to the effect that, as
of the date of such opinion, based on and subject to the matters set forth in
such opinion, the consideration of 0.8082 of a share of Ahmanson Common Stock
and the proportionate interest in an amount equal to any recovery on the
Litigation (the "Consideration") to be received by the holders of shares of
Coast Common Stock pursuant to the Merger Agreement is fair from a financial
point of view to such holders. Goldman Sachs has confirmed its October 5, 1997
opinion as of the date of this Proxy Statement/Prospectus by delivery of its
written opinion to the Coast Board, dated the date of this Proxy
Statement/Prospectus.

        Goldman Sachs has consented to the inclusion of its opinion, dated the
date hereof, in this Proxy Statement/Prospectus (the "Goldman Sachs Opinion").
The Goldman Sachs Opinion is addressed to the Coast Board and does not
constitute a recommendation to any of the stockholders of Coast as to how such
stockholders should vote with respect to the Merger.

        THE FULL TEXT OF THE GOLDMAN SACHS OPINION, DATED THE DATE OF THIS PROXY
STATEMENT/PROSPECTUS, WHICH SETS FORTH THE ASSUMPTIONS MADE, PROCEDURES
FOLLOWED, MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS
APPENDIX D TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY
REFERENCE. THE DESCRIPTION OF THE GOLDMAN SACHS OPINION SET FORTH HEREIN IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO APPENDIX D. COAST STOCKHOLDERS ARE
URGED TO READ THE GOLDMAN SACHS OPINION IN ITS ENTIRETY.

        Goldman Sachs is a nationally recognized investment banking firm and was
selected by Coast based on the firm's reputation and experience in investment
banking in general, its recognized expertise in the valuation of businesses and
because of its familiarity with, and prior work for, Coast. As part of its
investment banking business, Goldman Sachs




                                      -31-
<PAGE>   39

is continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes.

        In connection with rendering its opinions dated October 5, 1997 and the
date hereof, Goldman Sachs, among other things: (i) reviewed the Merger
Agreement; (ii) reviewed Annual Reports to Stockholders and Annual Reports on
Form 10-K of Coast and Ahmanson for the five years ended December 31, 1996;
(iii) reviewed certain interim reports to stockholders and Quarterly Reports on
Form 10-Q of Coast and Ahmanson; (iv) reviewed certain other communications from
Coast and Ahmanson to their respective stockholders; (v) reviewed certain
internal financial analyses and forecasts for Coast and Ahmanson prepared by
their respective managements, including forecasts of certain cost savings (the
"Synergies") expected by Ahmanson to be achieved as a result of the Merger and
including share repurchase and capital management policies expected to be
fulfilled by Ahmanson following the Merger; (vi) held discussions with members
of the senior managements of Coast and Ahmanson regarding the past and current
business operations, regulatory relationships, financial condition and future
prospects of their respective companies and each senior management's assessment
of the Synergies; (vii) reviewed the reported price and trading activity for the
Coast Common Stock and the Ahmanson Common Stock; (viii) compared certain
financial and stock market information for Coast and Ahmanson with similar
information for certain other companies the securities of which are publicly
traded; (ix) reviewed the financial terms of certain recent business
combinations in the thrift industry specifically and in other industries
generally; and (x) performed such other studies and analyses as Goldman Sachs
deemed appropriate.

        In connection with rendering the Goldman Sachs Opinion, as set forth
therein, Goldman Sachs relied without independent verification upon the accuracy
and completeness of all the financial and other information reviewed by it and
has assumed such accuracy and completeness for purposes of such opinion. With
Coast's consent, Goldman Sachs assumed that the financial forecasts of Coast and
Ahmanson (including, without limitation, the Synergies, the financial impact of
the anticipated repurchase of Ahmanson Common Stock and capital management
policies and the projections regarding under-performing and non-performing
assets and net charge-offs) were reasonably prepared on a basis reflecting the
best currently available judgments and estimates of Coast and Ahmanson, and that
such forecasts would be realized in the amounts and at the times contemplated
thereby. Goldman Sachs is not an expert in the evaluation of loan and lease
portfolios for purposes of assessing the adequacy of the allowances for losses
with respect thereto, and assumed, with Coast's consent, that such allowances
for each of Coast and Ahmanson are in the aggregate adequate to cover all such
losses. In addition, Goldman Sachs has not reviewed individual credit files nor
has it made an independent evaluation or appraisal of the assets and liabilities
of Coast or Ahmanson or any of their respective subsidiaries and has not been
furnished with any such evaluation or appraisal. Goldman Sachs has also assumed,
with Coast's consent, that obtaining any necessary regulatory approval and third
party consents for the Merger will not have an adverse impact on Coast, Ahmanson
or the combined company pursuant to the Merger.

        Goldman Sachs is not a legal expert and has not expressed any opinion as
to the potential outcome or value of the Litigation and has not expressed any
opinion as to the prices at which the CPR Certificates may trade if and when
they are issued.

        The following is a summary of the material financial analyses presented
by Goldman Sachs to the Coast Board on September 21, 1997 and October 5, 1997 in
connection with providing its opinion to the Coast Board on October 5, 1997, and
does not purport to be a complete description of the analyses performed by
Goldman Sachs. Goldman Sachs used substantially the same types of financial
analyses in preparing its written opinion dated as of the date of this Proxy
Statement/Prospectus as it used in providing its opinion dated as of October 5,
1997.

        Summary of Terms of Proposed Transaction. Goldman Sachs reviewed the
terms of the proposed Merger, including the form of Consideration offered, the
expected method of accounting and the Notional Value (defined below) to be
received for each share of Coast Common Stock pursuant to the Merger. The
Notional Value is calculated on the basis of (i) the Exchange Ratio, (ii) the
closing price of Ahmanson Common Stock as of October 3, 1997 and (iii) the
implied value of the Litigation.




                                      -32-
<PAGE>   40

        Goldman Sachs indicated that the Consideration offered in connection
with the Merger consists of Ahmanson Common Stock and proportionate interests in
an amount equal to the net after-tax proceeds, if any, that may be received in
the Litigation, which will be represented by the CPR Certificates. The
anticipated method of accounting for the Merger is the purchase method. Goldman
Sachs stated that the notional price per share of Coast Common Stock for the
Merger as of October 3, 1997 was $59.10 (the "Notional Value"), which amount
represents the sum of (i) the product of the Exchange Ratio and the $57.125
closing price of the Ahmanson Common Stock on October 3, 1997, or $46.17 (the
"Stock Consideration") and (ii) the implied value per share of Coast Common
Stock of the Litigation (as described below), or $12.93. The Notional Value is
necessarily dependent on the closing prices of the Ahmanson Common Stock and of
the Goodwill Certificates (defined below) issued by California Federal Bank at a
specific time. Based upon the Notional Value, the aggregate Consideration to be
received by holders of Coast Common Stock in the Merger would be approximately
$1.162 billion.

        In addition to reviewing the Notional Value resulting from the Merger,
the analyses described indicated values of the Stock Consideration resulting
from the Merger expressed as multiples of Coast's earnings for the 12 months
ended June 30, 1997 and of estimates of Coast's 1997 and 1998 earnings, as well
as multiples of various measures of Coast book value. In performing these
analyses, Goldman Sachs used estimates based upon IBES earnings estimates and
earnings estimates prepared by Coast management. IBES is a data service that
monitors and publishes compilations of earnings estimates by selected research
analysts regarding companies of interest to institutional investors. Using these
analyses, the Stock Consideration as of October 3, 1997 reflected (i) a multiple
of 19.7 times Coast earnings per share for the 12 months ending June 30, 1997,
(ii) multiples of 17.4 and 17.0 times the IBES median estimate and the Coast
management estimate, respectively, of Coast's 1997 earnings, and (iii) multiples
of 14.7 and 12.6 times the IBES median estimate and the Coast management
estimate of Coast's 1998 earnings, respectively. The indicated value of the
Stock Consideration as of October 3, 1997 also reflected (i) a multiple of 2.0
times Coast's stated book value as of June 30, 1997 and (ii) a multiple of 2.0
times Coast's tangible book value as of June 30, 1997.

        Valuation of Contingent Payment Rights. The possibility exists that
Coast may receive a material payment from the federal government as compensation
for damages related to the Litigation. In attempting to consider the value to
stockholders of any such payment, Goldman Sachs considered the current trading
value of certain publicly traded certificates (the "Goodwill Certificates")
issued by California Federal Bank ("California Federal") in July 1995.
California Federal agreed to pay to holders of the Goodwill Certificates, which
were issued to all of its then existing shareholders, a portion of any damages
which California Federal might receive in relation to its supervisory goodwill
lawsuit, a lawsuit which raises similar issues to those involved in the
Litigation (although there can be no assurance that the Coast and California
Federal litigation will be resolved in a similar manner). The market value of
these Goodwill Certificates, divided by the supervisory goodwill required to be
written off by California Federal, provides a percentage basis upon which it is
possible to impute a value to other companies' regulatory capital claims
(including that of Coast) by multiplying the supervisory goodwill or capital
credits required to be written off, phased out or excluded from regulatory
capital by such companies by such percentage. However, the actual damages that
may be awarded to a plaintiff institution may differ significantly from the
amount of supervisory goodwill or capital credits required to be written off,
phased out or excluded from regulatory capital, as the case may be, because a
court would take into account the actual damages suffered by a plaintiff thrift
as a result of the required phase-out or exclusion.

        Based on the $21.125 per certificate closing price of the Goodwill
Certificates on October 3, 1997, the ratio of the market value of the California
Federal legal claim to the aggregate amount of supervisory goodwill related
thereto was 87.5%. Applying this ratio to Coast's regulatory capital credit of
approximately $299 million implied a market value of $261 million, or $12.93 per
share of Coast Common Stock, attributable to the Litigation. However, although
the trading price of the Goodwill Certificates provides a likely indicator of
the market value of the Coast Common Stock attributable to the Litigation, there
is no assurance that the CPR Certificates will trade at $12.95.

        Selected Transaction Analysis. Goldman Sachs reviewed certain
information relating to 9 thrift institution mergers in California, announced
since January 1, 1994 and prior to October 5, 1997, in which the aggregate
consideration paid was in excess of $100 million (the "California Thrift
Mergers"). The California Thrift Mergers consist of (buyer/seller): Golden
State/CENFED Financial, Bay View Capital/America First, Washington Mutual/Great
Western, Temple-Inland/California Financial, MacAndrews & Forbes/Cal Fed
Bancorp, Washington Mutual/Keystone Holdings,




                                      -33-
<PAGE>   41

MacAndrews & Forbes/SFFed, First Interstate/Sacramento Savings and MacAndrews &
Forbes/First Nationwide. Such analysis indicated that the median multiples of
consideration paid to the latest 12 month earnings per share, current year
earnings, next year earnings, book value and tangible book value for the
California Thrift Mergers were 14.9, 12.5, 11.5, 1.6 and 1.6 times,
respectively, compared to multiples of the indicated value of the Stock
Consideration as of October 3, 1997 of (i) 19.7 times Coast earnings per share
for the 12 months ending June 30, 1997, (ii) 17.4 and 17.0 times the IBES median
estimate and the Coast management estimate, respectively, of Coast 1997
earnings, (iii) 14.7 and 12.6 times the IBES median estimate and the Coast
management estimate of Coast 1998 earnings, (iv) 2.0 times Coast's stated book
value as of June 30, 1997, and (v) 2.0 times Coast's tangible book value as of
June 30, 1997.

        Selected Company Analysis. Based on publicly available information and
IBES earnings estimates, Goldman Sachs reviewed and compared (both including and
excluding the value attributable to the applicable company's regulatory capital
litigation) actual and estimated selected financial, operating and stock market
information and financial ratios of Coast and Ahmanson, a group of 2 California
large-capitalization thrift institutions consisting of Washington Mutual and
Golden West Financial (the "Selected California Large-Cap Thrifts"), a group of
4 California mid- capitalization thrift institutions consisting of Golden State,
Downey Financial, FirstFed Financial and Bay View Capital (the "Selected
California Mid-Cap Thrifts"), and a group of 6 selected non-California
large-capitalization thrift institutions consisting of Charter One Financial,
GreenPoint Financial, Dime Bancorp, Washington Federal, Bank United and People's
Heritage (the "Selected Non-California Large-Cap Thrifts"). Such information and
ratios included, among other things, equity market capitalization,
price-earnings ratios, price to book value ratios, price to tangible book value
ratios, earnings growth and certain profitability data.

        Goldman Sachs noted for the Coast Board that, among other things, and
excluding the value attributable to the applicable company's regulatory capital
litigation: (i) Ahmanson had a ratio of market price to 1997 and 1998 IBES
estimated earnings as of September 19, 1997 of 17.1 and 14.7, respectively, as
compared with 19.0 and 16.0, respectively, for Coast and a median ratio of
market price to 1997 and 1998 IBES estimated earnings as of September 19, 1997
of 16.6 and 14.0 for the Selected California Large-Cap Thrifts, 17.2 and 14.4
for the Selected California Mid-Cap Thrifts and 16.0 and 14.0 for the Selected
Non-California Large Cap Thrifts; (ii) Ahmanson had a ratio of market price to
book value, as of September 19, 1997, of 2.8, as compared with 2.1 for Coast and
a median ratio of market price to book value for Selected California Large-Cap
Thrifts, Selected California Mid-Cap Thrifts and Selected Non-California
Large-Cap Thrifts, as of September 19, 1997, of 2.8, 1.7 and 2.1, respectively;
and (iii) Ahmanson had a ratio of market price to tangible book value, as of
September 19, 1997, of 3.3, as compared with 2.1 for Coast and a median ratio of
market price to tangible book value for Selected California Large-Cap Thrifts,
Selected California Mid-Cap Thrifts and Selected Non- California Large-Cap
Thrifts, as of September 19, 1997, of 2.9, 1.9 and 2.6, respectively.

        Goldman Sachs also noted for the Coast Board that, among other things,
and including the value attributable to the applicable company's regulatory
capital litigation: (i) Ahmanson had a ratio of market price to 1997 and 1998
IBES estimated earnings as of September 19, 1997 of 15.6 and 13.3, respectively,
as compared with 14.2 and 11.9, respectively, for Coast and a median ratio of
market price to 1997 and 1998 IBES estimated earnings as of September 19, 1997
of 16.6 and 14.0 for the Selected California Large-Cap Thrifts, 16.5 and 12.7
for the Selected California Mid-Cap Thrifts and 14.7 and 13.0 for the Selected
Non-California Large Cap Thrifts; (ii) Ahmanson had a ratio of market price to
book value, as of September 19, 1997, of 2.5, as compared with 1.6 for Coast and
a median ratio of market price to book value for Selected California Large-Cap
Thrifts, Selected California Mid-Cap Thrifts and Selected Non-California
Large-Cap Thrifts, as of September 19, 1997, of 2.8, 1.7 and 2.1, respectively;
and (iii) Ahmanson had a ratio of market price to tangible book value, as of
September 19, 1997, of 3.0, as compared with 1.7 for Coast and a median ratio of
market price to tangible book value for Selected California Large-Cap Thrifts,
Selected California Mid-Cap Thrifts and Selected Non- California Large-Cap
Thrifts, as of September 19, 1997, of 2.9, 1.7 and 2.4, respectively.

        Discounted Cash Flow Analysis. Using a discounted cash flow analysis,
Goldman Sachs estimated the present value of the future dividend streams, share
repurchases and terminal values (without reference to the Litigation) that Coast
could produce over the four-year period from January 1, 1998 to December 31,
2001. The estimate of Coast's future net income assumed earnings growth for the
four-year period based on Coast management's earnings estimates and on IBES
earnings estimates. Using assumed discount rates of 11.0%, 12.0% and 13.0% and
terminal values based on multiples of price to forward earnings for the 12-month
period ending December 31, 2002 ranging from 11.0 times




                                      -34-
<PAGE>   42

to 13.0 times, Goldman Sachs calculated net present values ranging from $31 to
$46 per share of Coast Common Stock for the four-year period, excluding proceeds
from the Litigation. The analysis assumed no dividends, and ongoing repurchases
in amounts consistent with Coast's target capital ratios. This compares with the
indicated values of the Stock Consideration of $46.17 per share of Coast Common
Stock included in the Notional Value.

        Pro Forma Analysis. Goldman Sachs also performed a pro forma analysis of
certain other financial aspects of the Merger, calculating, among other things,
the pro forma ratios of common equity to assets and tangible common equity to
tangible assets and the efficiency ratio of the combined entity to be 5.0%, 3.8%
and 44.6%, respectively and calculating the pro forma return on average equity
and return on average assets, on a GAAP and on a cash basis, of the combined
entity to be 16.3% and 0.82%, and 17.8% and 0.90%, respectively. Goldman Sachs
also analyzed the pro forma impact on estimated earnings per share of the
combined entity on a reported GAAP and on a cash (excluding goodwill
amortization) basis. On a reported GAAP basis, Goldman Sachs calculated pro
forma earnings per share accretion of 2.0% and 6.1% (using IBES earnings
estimates for both Coast and Ahmanson) for 1998 and 1999, respectively, and 3.1%
and 8.2% (using earnings per share estimates provided by the management of both
Coast and Ahmanson) for 1998 and 1999, respectively. On a cash basis, Goldman
Sachs calculated pro forma earnings per share accretion of 4.2% and 8.7% (using
IBES earnings per share estimates for both Coast and Ahmanson) for 1998 and
1999, respectively, and 5.2% and 10.5% (using earnings estimates provided by the
management of both Coast and Ahmanson) for 1998 and 1999, respectively.

        The pro forma merger analysis assumed, among other things, that the
pre-tax expense savings realized from the merger would be $37.5 million in 1998
and $75.0 million in 1999 and thereafter. Goldman Sachs assumed a pretax
restructuring reserve of $75.0 million and a transaction closing date of March
31, 1998. Goldman Sachs also calculated pro forma share repurchases for Ahmanson
to target a pro forma ratio of tangible common equity to tangible assets for
Ahmanson of 4.25%. Additionally, Goldman Sachs assumed that goodwill created in
the transaction would be amortized over a period of 25 years.

        Other Analyses. Goldman Sachs also reviewed, among other things,
selected investment research reports on, and earnings estimates for, Coast
Common Stock and Ahmanson Common Stock. Goldman Sachs prepared a summary of the
historical financial and market performance of Coast and Ahmanson, summarized
Coast and Ahmanson managements' respective estimates of financial performance in
1997, based on publicly available information, and analyzed Coast's and
Ahmanson's deposit market share and branch presence in the regions in which they
operate.

        The summary set forth above describes the material analyses that Goldman
Sachs performed and presented to the Coast Board on September 21, 1997 and
October 5, 1997, and does not purport to be a complete description of such
analyses. The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or a summary description.

        Goldman Sachs believes that its analyses must be considered as a whole
and that selecting portions of its analyses without considering all factors and
analyses would create an incomplete view of the analyses and processes
underlying its opinion. In its analyses, Goldman Sachs relied upon numerous
assumptions made by Coast and Ahmanson with respect to industry performance,
general business and economic conditions and other matters, many of which are
beyond the control of Coast or Ahmanson. Analyses based upon forecasts of future
results are not necessarily indicative of actual values, which may be
significantly more or less favorable than suggested by such analyses. No company
or transaction used as a comparison in the analyses is identical to Coast or
Ahmanson or to the Merger. Additionally, estimates of the value of businesses do
not purport to be appraisals or necessarily reflective of the prices at which
businesses actually may be sold. Because such estimates are inherently subject
to uncertainty, none of the Coast Board, Goldman Sachs, Ahmanson or any other
person assumes responsibility for the accuracy of such estimates. Goldman Sachs'
analyses were prepared solely for purposes of its opinions rendered October 5,
1997 and the date of this Proxy Statement/Prospectus provided to the Coast Board
regarding the fairness from a financial point of view of the Consideration
received by holders of Coast Common Stock pursuant to the Merger Agreement, and
do not purport to be appraisals or necessarily reflect the prices at which Coast
or its securities actually may be sold.




                                      -35-
<PAGE>   43

        For the services of Goldman Sachs as financial advisor to Coast in
connection with the Merger, pursuant to an engagement letter dated August 26,
1997, Coast has agreed to pay Goldman Sachs a transaction fee of 0.65% of the
aggregate consideration paid in connection with the Merger (not including
amounts payable in respect of the Litigation); provided, however, that such fee
may not be more than 0.65 multiplied by 110% of the "transaction value" at the
date of the Merger Agreement and may not be less than 0.65 multiplied by 90% of
the "transaction value" at the date of the Merger Agreement. Coast has also
agreed to pay Goldman Sachs its reasonable out-of-pocket expenses, including the
fees and disbursements of its counsel, and to indemnify Goldman Sachs against
certain liabilities, including certain liabilities arising under the federal
securities laws. Goldman Sachs has provided certain investment banking and
advisory services to Coast from time to time, for which it has received, and
will receive, customary compensation. In addition, Goldman Sachs has provided,
and may provide in the future, certain investment banking services to Ahmanson,
for which it has received, and will receive, customary compensation.

        Goldman Sachs has advised Coast that, in the ordinary course of its
business as a full-service securities firm, Goldman Sachs may, subject to
certain restrictions, actively trade the equity and/or debt securities of Coast
or Ahmanson for its own account or for the accounts of its customers, and,
accordingly, may at any time hold a long or short position in such securities.

REASONS OF AHMANSON FOR THE MERGER

        Ahmanson believes that the Merger enhances Ahmanson's presence in key
markets throughout California, as well as Ahmanson's ability to offer financial
products to both individuals and small businesses. In addition, the Merger
provides an opportunity to enhance Ahmanson's stockholder value by increasing
earnings per share, reducing costs and enhancing revenue growth prospects.

EFFECTIVE TIME

        If the Transaction Proposal is approved by the requisite vote of the
Coast stockholders, all required governmental and other consents and approvals
are obtained and the other conditions to the obligations of the parties to
consummate the Merger are either satisfied or waived (if permitted), the CPR
Certificate Distribution will be effected on the Effective Date with a record
and payment date on the Effective Date immediately prior to the Effective Time
and the Merger will be consummated and will become effective on the Effective
Date and at the Effective Time (which will be the time that a certificate of
merger reflecting the Merger is filed with the Secretary of State of the State
of Delaware or at the time specified in such certificate). Unless otherwise
agreed by Coast and Ahmanson, and subject to the conditions to the obligations
of the parties to effect the Merger, the parties have agreed to cause the
Effective Date to occur on the fifth business day to occur after the last of the
conditions to the consummation of the Merger have been satisfied or waived (or,
at the election of Ahmanson, on the last business day of the month in which such
date occurs or, if such date occurs on one of the last five business days of
such month, on the last business day of the succeeding month). Ahmanson and
Coast each has the right, acting unilaterally, to terminate the Merger Agreement
should the Merger not be consummated by June 30, 1998. See "--Termination;
Termination Fee."

DISTRIBUTION OF AHMANSON COMMON STOCK CERTIFICATES

        At or prior to the Effective Time, Ahmanson will deposit, or will cause
to be deposited, with a depository institution of recognized standing selected
by Ahmanson (in such capacity, the "Exchange Agent"), for the benefit of the
holders of certificates formerly representing shares of Coast Common Stock ("Old
Certificates") certificates representing the shares of Ahmanson Common Stock
("New Certificates") to which the holders of the Old Certificates are entitled
pursuant to the Merger Agreement, together with the estimated amount of cash to
be paid in exchange for fractional share interests.

        Promptly after the Effective Time, Ahmanson will send or cause to be
sent transmittal materials to each record holder of Coast Common Stock for use
in exchanging those certificates for the shares of Ahmanson Common Stock to
which such stockholder is entitled as a result of the Merger. COAST STOCKHOLDERS
SHOULD NOT SURRENDER THEIR CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE THE
LETTER OF




                                      -36-
<PAGE>   44

TRANSMITTAL AND INSTRUCTIONS. Ahmanson will cause the New Certificates and/or
any check in respect of any fractional share interests or dividends or
distributions which a holder of Coast Common Stock will be entitled to receive
to be delivered to such stockholder upon delivery to the Exchange Agent of
certificates representing such shares of Coast Common Stock owned by such
stockholder (or indemnity reasonably satisfactory to Ahmanson and the Exchange
Agent, if any of such certificates are lost, stolen or destroyed). None of the
Exchange Agent, Ahmanson, Coast or the CPR Trust will be liable to a holder of
Coast Common Stock for any amount properly delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

        After the Effective Time, at the election of Ahmanson, no dividend or
other distribution with respect to Ahmanson Common Stock with a record date
occurring after the Effective Time will be paid to the holder of any
unsurrendered certificate for Coast Common Stock until the holder duly
surrenders such certificate. Upon such surrender, all undelivered dividends and
other distributions and, if applicable, a check for the amount to be paid in
lieu of any fractional share interest will be delivered to such stockholder, in
each case without interest.

        After the Effective Time, there will be no transfers of shares of Coast
Common Stock on Coast's stock transfer books. If certificates representing
shares of Coast Common Stock are presented for transfer after the Effective
Time, they will be canceled and exchanged for the shares of Ahmanson Common
Stock and a check for the amount due in lieu of fractional shares, if any,
deliverable in respect thereof.

FRACTIONAL SHARES

        Pursuant to the terms of the Merger Agreement, each holder of shares of
Coast Common Stock exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fraction of a share of Ahmanson Common Stock shall
receive, in lieu thereof, an amount in cash (without interest) determined by
multiplying such fraction by the average of the last sale prices of Ahmanson
Common Stock, as reported by the NYSE Composite Tape (as reported in The Wall
Street Journal or, if not reported therein, in another authoritative source),
for the five NYSE trading days immediately preceding the Effective Date. No such
holder will be entitled to dividends, voting rights, or any other rights as a
stockholder with respect to any fractional shares. No interest will be paid on
any such cash to be paid in lieu of fractional share interests or in respect of
dividends or distributions which any such person may be entitled to receive upon
delivery of Old Certificates to the Exchange Agent.

THE CPR TRUST, THE CPR CERTIFICATES AND THE CPR CERTIFICATE DISTRIBUTION

        In the Merger Agreement, Coast has agreed to take all actions necessary
to cause the CPR Trust to be formed. In addition, Coast has agreed to take all
actions necessary to cause the issuance of the CPR Certificates by the CPR Trust
to Coast and to effect the CPR Certificate Distribution with a record date and
payment date on the Effective Date immediately prior to the Effective Time.
However, Coast is not required to cause the CPR Trust to issue such CPR
Certificates or to effect the CPR Certificate Distribution until all conditions
to the Merger, other than such distribution, have been satisfied or waived. See
"--Conditions to Consummation."

        Coast has also agreed to cause the CPR Trust to deliver to Coast
immediately prior to the Effective Time a number of CPR Certificates sufficient
for the delivery (or retention by Ahmanson as successor to Coast in certain
circumstances) of CPR Certificates required in connection with Coast Stock
Options, Coast Performance Share Awards, Coast SARs and appraisal rights that
are exercised. See "--Stock Options; Performance Share Awards; SARs" and
"Appraisal Rights." Ahmanson has agreed to return to the CPR Trust any CPR
Certificates with respect to options that expire prior to exercise.

STOCK OPTIONS; PERFORMANCE SHARE AWARDS; SARS

        The Merger Agreement provides that each option to acquire shares of
Coast Common Stock (each, a "Coast Stock Option") which is outstanding at the
Effective Time, all of which are vested, will be converted into an option to
acquire, on the same terms and conditions as were applicable under Coast's 1996
Equity Incentive Plan or Coast's 1985 Stock Option and Stock Appreciation Rights
Plan (collectively, the "Coast Stock Plans"), as the case may be, (a) the




                                      -37-

number of shares of Ahmanson Common Stock equal to (i) the number of shares of
Coast Common Stock subject to such Coast Stock Option, multiplied by (ii) the
Exchange Ratio (such product rounded down to the nearest whole number), at an
exercise price per share (rounded up to the nearest whole cent) equal to (A) the
aggregate exercise price for the shares of Coast Common Stock which were
purchasable pursuant to such Coast Stock Option divided by (B) the number of
full shares of Ahmanson Common Stock subject to the Replacement Option in
accordance with the foregoing and (b) one CPR Certificate for each share of
Coast Common Stock that would have been issuable upon exercise in full of such
Coast Stock Option.

        In addition, the Merger Agreement provides that each performance share
award (each, a "Coast Performance Share Award") which is outstanding at the
Effective Time under the Coast Performance Share Plan for Key Employees (the
"Coast Performance Share Award Plan") will be canceled and will only entitle the
holder thereof to receive for each share of Coast Common Stock with respect to
such award (a) one CPR Certificate and (b) an amount in cash equal to the
difference between (i) the result of multiplying the Exchange Ratio by the
average of the last sale prices of one share of Ahmanson Common Stock, as
reported by the NYSE Composite Tape (as reported in The Wall Street Journal or,
if not reported therein, in another authoritative source), for the five NYSE
trading days immediately prior to the Effective Date and (ii) the base price
under such award.

        The Merger Agreement further provides that each outstanding stock
appreciation right (each, a "Coast SAR") under the Coast Stock Plans shall be
canceled and only entitle the holder thereof to receive for each share of Coast
Common Stock with respect to such stock appreciation right (a) one CPR
Certificate and (b) an amount in cash equal to the difference between (i) the
result of multiplying the Exchange Ratio by the average of the last sale prices
of one share of Ahmanson Common Stock, as reported by the NYSE Composite Tape
(as reported in The Wall Street Journal or, if not reported therein, in another
authoritative source), for the five NYSE trading days immediately prior to the
Effective Date and (ii) the grant price of such Coast SAR.

        However, if Coast is unable to obtain from any holders of such Coast
Performance Share Awards or Coast SARs, as the case may be, the consents
necessary to effect such treatment, such holders will instead be entitled to (a)
with respect to each outstanding Coast Performance Share Award under the Coast
Performance Share Award Plan, an amount in cash equal to the result of
multiplying (i) the difference between the average of the last sale prices of
one share of Coast Common Stock, as reported by the NYSE Composite Tape (as
reported in The Wall Street Journal or, if not reported therein, in another
authoritative source), for the five NYSE trading days immediately prior to the
Effective Date and the base price under such award by (ii) the total number of
shares of Coast Common Stock with respect to such award and (b) with respect to
each outstanding Coast SAR under the Coast Stock Plans, an amount in cash equal
to the result of multiplying (i) the difference between the average of the last
sale prices of one share of Coast Common Stock, as reported by the NYSE
Composite Tape (as reported in The Wall Street Journal or, if not reported
therein, in another authoritative source), for the five NYSE trading days
immediately prior to the Effective Date and the grant price of such stock
appreciation right by (ii) the total number of shares of Coast Common Stock with
respect to such Coast SAR. All CPR Certificates with respect to the Coast
Performance Share Awards and Coast SARs as to which payments are made as
described in this paragraph will be retained by Ahmanson (as successor to
Coast). In addition, in the event that between the date of the Merger Agreement
and the Effective Date any Coast Performance Share Awards or Coast SARs are
exercised, Ahmanson (as successor to Coast) will be entitled to retain any CPR
Certificates that would otherwise have been issuable with respect to such Coast
Performance Share Awards or Coast SARs at the Effective Date.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

        The following summary of the material U.S. federal income tax
consequences of the Merger applies to a holder of Coast Common Stock that holds
its shares as capital assets. This summary may not apply to certain classes of
taxpayers, including foreign holders, insurance companies, tax-exempt
organizations, financial institutions, dealers in securities, traders in
securities that elect to mark to market, persons who acquired or acquire shares
of Coast Common Stock pursuant to the exercise of employee stock options or
otherwise as compensation and persons who hold shares of Coast Common Stock in a
hedging transaction or as part of a straddle or conversion transaction. Each
holder should consult its own tax adviser as to the specific tax consequences of
the Merger and the CPR Certificate Distribution to such holder.




                                      -38-
<PAGE>   46

        This summary represents the opinions of Sullivan & Cromwell, special
counsel to Ahmanson, and Cleary, Gottlieb, Steen & Hamilton, special counsel to
Coast. The parties do not intend to request any ruling from the IRS as to the
U.S. federal income tax consequences of the Merger.

        The obligations of Ahmanson and Coast to consummate the Merger are
subject to the condition that they receive opinions (described further below) to
the effect that the Merger will be treated as a reorganization within the
meaning of Section 368(a) of the Code. In rendering such opinions, such counsel
may require and rely upon representations contained in letters from Coast,
Ahmanson and stockholders of Coast and assumptions set forth in the opinions.
Assuming the Merger is such a reorganization, the material federal income tax
consequences of the Merger to each of Ahmanson, Coast and a holder who exchanges
shares of Coast Common Stock for shares of Ahmanson Common Stock pursuant to the
Merger will be as follows:

             (a) No gain or loss will be recognized by Ahmanson or Coast as a
        result of the consummation of the Merger.

             (b) No gain or loss will be recognized by a holder except as
        follows: Gain or loss may be recognized by a holder who receives cash in
        lieu of a fractional share interest in Ahmanson Common Stock (see (e)
        below). In addition, gain (but not loss) may be recognized in an amount
        not exceeding the fair market value of such holder's CPR Certificates at
        the Effective Time (which will include a proportionate share of the
        value attributable to Ahmanson's having entered into the Commitment)
        (see (f) below).

             (c) The aggregate adjusted tax basis of shares of Ahmanson Common
        Stock (including any fractional share interest in Ahmanson Common Stock,
        as described below) received by a holder will be the same as the
        aggregate adjusted tax basis of the shares of Coast Common Stock
        exchanged therefor, decreased by the value of the CPR Certificates
        received by such holder (as such value is determined in (f)(i) below)
        and increased by the amount of gain recognized upon the receipt of CPR
        Certificates (as described in (f) below).

             (d) The holding period of shares of Ahmanson Common Stock
        (including a fractional share interest in Ahmanson Common Stock deemed
        received and redeemed, as described below) received by a holder will
        include the holding period of the Coast Common Stock exchanged therefor.

             (e) A holder who receives cash in lieu of a fractional share
        interest in Ahmanson Common Stock will be treated as having received the
        fractional share interest and as having received the cash in redemption
        of that fractional share interest. Under Section 302 of the Code, if the
        deemed redemption is "substantially disproportionate" with respect to
        the holder or is "not essentially equivalent to a dividend" after giving
        effect to the constructive ownership rules of the Code, the holder will
        generally recognize capital gain or loss equal to the difference between
        the amount of cash received and the holder's adjusted tax basis in the
        fractional share interest (determined under clause (c) above). Such
        capital gain or loss will be long-term capital gain or loss if the
        holder's holding period in the fractional share interest (determined
        under clause (d) above) is more than one year (and will be taxed at the
        rates set forth in the final sentence of (f) below).

             (f) A holder will recognize gain to the extent of the lesser of:

                  (i) the fair market value of the holder's CPR Certificates at
               the Effective Time (which, at the Effective Time, will include
               the proportionate share of the value attributable to Ahmanson's
               having entered into the Commitment); and

                  (ii)the excess of (A) the sum of (I) the fair market value of
               the shares of Ahmanson Common Stock (including any fractional
               share interest in Ahmanson Common Stock for which cash is
               received) received by the holder and (II) the amount determined
               in (i) above; over (B) the holder's adjusted federal income tax
               basis for the shares of Coast Common Stock exchanged in the
               Merger.

        If the shares of Coast Common Stock exchanged in the Merger were held as
        capital assets at the Effective Time, any such gain will be treated as
        capital gain (which will be long-term capital gain if the shares of
        Coast Common




                                      -39-
<PAGE>   47

        Stock were held for more than one year) provided the holder of Coast
        Common Stock does not own, either directly or applying certain ownership
        attribution rules, contemporaneously with the Merger any Ahmanson stock
        other than the Ahmanson Common Stock received by the holder in the
        Merger. A holder that owns such additional Ahmanson stock generally will
        be entitled to treat such gain as capital gain only if a distribution of
        CPR Certificates in a hypothetical redemption by Ahmanson immediately
        following the Effective Time of an equivalent amount of Ahmanson Common
        Stock would have qualified for capital gain treatment under the
        standards of Section 302 of the Code. Holders owning additional shares
        of Ahmanson stock should consult their own tax advisors concerning the
        treatment of gain as capital gain or ordinary income. Long-term capital
        gain of a non-corporate holder is generally subject to a maximum tax
        rate of 28% in respect of property held for more than one year and to a
        maximum tax rate of 20% in respect of property held for more than 18
        months.

               (g) The adjusted tax basis of CPR Certificates received by a
        holder will equal the value of the CPR Certificates described in (f)(i)
        above, and the holding period of the CPR Certificates will begin on the
        Effective Date (and will not include the holding period of the holder's
        Coast Common Stock).

        Ahmanson's obligation to consummate the Merger is conditioned upon,
among other things, the receipt of an opinion of Sullivan & Cromwell, dated the
Effective Date, to the effect that the Merger is a reorganization under Section
368(a) of the Code and that no gain or income will be recognized by Ahmanson in
the Merger. Coast's obligation to consummate the Merger is conditioned upon,
among other things, the receipt of an opinion of Cleary, Gottlieb, Steen &
Hamilton, dated the Effective Date, to the effect that the Merger is a
reorganization within the meaning of Section 368(a) of the Code and that,
accordingly, (i) no gain or loss will be recognized by Coast as a result of the
Merger and (ii) no gain or loss will be recognized by a stockholder of Coast who
receives shares of Ahmanson Common Stock in exchange for shares of Coast Common
Stock, except (A) with respect to cash received in lieu of fractional share
interests and (B) for gain that may be recognized in an amount not exceeding the
fair market value at the time of the Merger of such stockholder's CPR
Certificates (which represent such stockholder's share of the Commitment
Amount). The opinion of Cleary, Gottlieb, Steen & Hamilton will not apply to
stockholders or persons receiving Ahmanson Common Stock or CPR Certificates as
compensation.

        Under the terms of the Merger Agreement, the conditions to the Merger,
including receipt by each party of opinions of counsel relating to tax matters,
may generally be waived by Ahmanson or Coast, as applicable. See "--Conditions
to Consummation" and "--Amendment and Waiver."

        BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON
THE PARTICULAR CIRCUMSTANCES OF EACH HOLDER OF COAST COMMON STOCK AND OTHER
FACTORS, EACH SUCH HOLDER IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISER AS
TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO SUCH HOLDER (INCLUDING THE
APPLICATION AND EFFECT OF STATE AND LOCAL INCOME AND OTHER TAX LAWS).

MANAGEMENT AND OPERATIONS AFTER THE MERGER

        Ahmanson will be the surviving corporation resulting from the Merger and
will continue to be governed by the laws of the State of Delaware and will
operate in accordance with its certificate of incorporation and bylaws as in
effect immediately prior to the Effective Time until otherwise amended or
repealed after the Effective Time. Under the Merger Agreement, Ahmanson has
agreed to cause Mr. Martin, Chairman of the Board and Chief Executive Officer of
Coast, to be elected or appointed as director of Ahmanson at, or as promptly as
practicable after, the Effective Time. The directors and officers of Ahmanson in
office immediately prior to the Effective Time, together with such additional
director and such additional persons as may thereafter be elected, will serve as
the directors and officers of Ahmanson from and after the Effective Time in
accordance with Ahmanson's certificate of incorporation and bylaws.

<PAGE>   48

POST-ACQUISITION COMPENSATION AND BENEFITS

        The Merger Agreement provides generally that Ahmanson will, from and
after the Effective Time, (a) honor in accordance with their terms all
employment or severance agreements entered into prior to the date of the Merger
Agreement that were previously disclosed, (b) provide former employees of Coast
who remain as employees of Ahmanson with employee benefit plans no less
favorable in the aggregate than those provided to similarly situated employees
of Ahmanson, (c) provide employees of Coast who remain as employees of Ahmanson
credit for years of service with Coast or any of its subsidiaries prior to the
Effective Time for the purpose of eligibility and vesting and (d) cause any and
all pre-existing condition limitations (to the extent such limitations did not
apply to a pre-existing condition under comparable compensation and benefit
plans of Coast) and eligibility waiting periods under group health plans of
Ahmanson to be waived with respect to former employees of Coast who remain as
employees of Ahmanson (and their eligible dependents) and who become
participants in such group health plans. The Merger Agreement provides, however,
that nothing therein will limit or restrict the right of Ahmanson to (i)
terminate the employment of any employee at any time for any reason whatsoever,
with or without cause, and (ii) modify, amend or terminate any employee benefit
or other plans of Ahmanson. In the Merger Agreement, Ahmanson agreed to pay up
to $2,000,000 as retention bonuses, payable upon dates following consummation of
the Merger specified in the Merger Agreement, to be allocated primarily among
non-executive employees of Coast.

        On October 27, 1997, Ahmanson and Coast announced the adoption of the
Coast Federal Bank, Federal Savings Bank Change in Control Severance Pay Plan
(the "Severance Plan") effective from November 1, 1997 with respect to certain
employees of Coast. Ahmanson and Coast have agreed that the adoption of the
Severance Plan is deemed to satisfy and constitutes full performance by Ahmanson
of its obligations described in the last sentence of the immediately preceding
paragraph. The Severance Plan generally provides that employees of Coast Federal
whose employment is terminated without cause as a consequence of the Merger or
the consolidation of branches prior to December 31, 1998 will receive severance
compensation based upon the length of their service with Coast Federal.

INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION PROPOSAL

        Certain members of Coast's management and the Coast Board may be deemed
to have certain interests in the Merger and the transactions contemplated
thereby in addition to their interests as Coast stockholders. The Coast Board
was aware of these interests in approving the Merger Agreement.

        AHMANSON BOARD OF DIRECTORS.

        As described above, the Merger Agreement provides that Ahmanson agrees
to cause Mr. Martin, Chairman of the Board and Chief Executive Officer of Coast,
to be elected or appointed as a director of Ahmanson at, or as promptly as
practicable after, the Effective Time.

        INCENTIVE PLANS.

        The Merger Agreement provides that all options to acquire Coast Common
Stock outstanding at the Effective Time under the Coast Stock Plans, including
those held by management and members of the Coast Board, will be assumed by
Ahmanson. Each stock option will thereafter constitute an option to acquire
shares of Ahmanson Common Stock and CPR Certificates as set forth above under
"--Stock Options; Performance Share Awards; SARs." In addition, the Merger
Agreement provides that each outstanding Coast Performance Share Award under the
Coast Performance Share Award Plan and each outstanding Coast SAR, including
those held by management, will be canceled (subject to the consent of the holder
of such Coast Performance Share Award or Coast SAR, as the case may be) and
entitle the holder thereof to a CPR Certificate and an amount in cash generally
based on an average of the Ahmanson Common Stock over a five day period over the
base price or grant price, as applicable. See "--Stock Options; Performance
Share Awards; SARs."

<PAGE>   49

        INDEMNIFICATION AND INSURANCE.

        The Merger Agreement provides that following the Effective Date,
Ahmanson will indemnify, defend and hold harmless the present directors and
officers of Coast and its subsidiaries against all costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages or
liabilities as incurred, in connection with any claim, action, suit, proceeding
or investigation, whether civil, criminal, administrative or investigative,
arising out of actions or omissions occurring at or prior to the Effective Time
to the fullest extent that Coast is permitted to indemnify (and advance expenses
to) its directors and officers under the laws of the State of Delaware, the
certificate of incorporation of Coast (the "Coast Charter") and the by-laws of
Coast (the "Coast By-Laws") as in effect on October 5, 1997. The Merger
Agreement also provides that Ahmanson will use its reasonable best efforts for
four years after the Effective Time to provide directors' and officers'
liability insurance that serves to reimburse the present and former officers and
directors of Coast or any of its subsidiaries with respect to claims against
such directors and officers arising from facts or events which occurred at or
prior to the Effective Time, which insurance will contain at least the same
coverage and amounts, and will contain terms and conditions no less
advantageous, as the coverage currently provided by Coast; provided, however,
that in no event will Ahmanson be required to expend more than 200% of the
current amount expended by Coast to maintain such insurance and that if Ahmanson
is unable to maintain or obtain such insurance, Ahmanson will use its reasonable
best efforts to obtain as much comparable insurance as is available for such
200% amount.

        COAST EXECUTIVE AGREEMENTS AND PLANS.

        Change of Control. The Merger will constitute a "change of control"
within the meaning of the agreements and plans described below.

        Employment Agreements. Coast Federal currently has employment agreements
with its Chief Executive Officer, President and Senior Executive Vice
Presidents, as well as certain other officers of Coast Federal and its
subsidiaries. Mr. Ray Martin's agreement provides for a three year term renewed
annually by the Coast Board. The agreements with Messrs. Robert Hunt, James
Boyle, Norman Raiden and James Barritt provide for two year terms renewed
annually by the Coast Board. However, in the event of a change in control of
Coast Federal, the term of such executives' agreements automatically converts to
three years renewable annually by the Board of Directors. In addition, in the
event of a change in control, for the remainder of the term of the agreement,
Coast Federal will pay each executive a base monthly compensation equal to his
monthly salary then in effect plus 1/12 of the aggregate amount of the higher of
the discretionary bonuses attributable to the last two bonus computation years
that ended before the change in control.

        In the event that Coast Federal elects to terminate any of the
executives' employment without cause (as defined therein), or if the executive
elects to terminate his employment (i) within one year of a change of control of
Coast Federal for any reason (with respect to Mr. Martin only), (ii) due to
Coast Federal's failure to comply with certain conditions of service (including
certain additional conditions following a change in control of Coast Federal) or
(iii) within the 30-day period immediately following the one year anniversary of
a change in control of Coast Federal, the affected executive will be entitled to
receive a lump sum payment within 30 days of such termination equal to the
discounted present value of the compensation due under the agreement for the
balance of its term. In addition, the executives will be entitled to receive
medical insurance benefits for the remaining term of the agreement. In the event
of a change in control, each executive will also receive a gross-up payment if
the payments and benefits under the agreement and all other contracts or
arrangements, in the aggregate, exceed the maximum amount that may be paid to
the executive without triggering golden parachute penalties under Section 280G
of the Code and related provisions. Such gross-up payment will be an amount
which, after payment by the executive of all income and excise taxes on the
gross-up payment, equals the excise taxes the executive must pay under Section
4999 of the Code with respect to the payments and benefits for which the
executive is receiving the gross-up payment.

        Severance Agreements. Coast Federal currently has severance agreements
with its _______ Senior Vice Presidents. The terms of such agreements commence
on the date of a change in control of Coast Federal and terminate one year from
the date of such change in control. Such agreements may be terminated earlier
upon 30 days notice by either party to the agreement, provided that if such
agreement is terminated by Coast Federal after a change in control, Coast
Federal will remain obligated to make payments under such agreement. If there
has been a change in control while




                                      -42-
<PAGE>   50

the executive is still employed by Coast Federal and during the term of the
agreement the executive's employment with Coast Federal is subsequently
terminated, the executive will be entitled to a severance payment, unless such
termination of employment was (i) as a result of the executive's death,
disability (as defined therein) or retirement (as defined therein), or (ii) by
Coast Federal for cause (as defined therein) or (iii) by the executive other
than for good reason (as defined therein). Such severance payment would be a
lump sum amount equal to one year's salary (at the higher of the executive's
salary at the time of the change in control or of the termination of the
executive's employment), payable 50% within 5 days of the executive's
termination of employment and the remainder within 60 days of such termination.

        Supplemental Executive Retirement Plan of Coast Federal. Coast Federal
currently has a non-qualified supplemental executive retirement plan (the
"Supplemental Plan") to provide supplemental retirement benefits to its Chief
Executive Officer, President, Senior Executive Vice Presidents, Senior Vice
Presidents and certain other senior officers of Coast Federal and its
subsidiaries. Monthly benefits are based upon a percent of such participant's
average monthly earnings during the three highest paid consecutive years in the
ten years preceding retirement. Monthly benefits payable under the Supplemental
Plan are reduced (but not below a specified percentage of such average monthly
earnings) by the sum of the benefit payable to the executive under Coast
Federal's qualified pension plan, Social Security and certain other payments. In
general, benefits payable under the Supplemental Plan are reduced if a
participant retires prior to attaining age 65. Participants are generally
eligible to receive benefits under the Supplemental Plan after the completion of
10 years of service with Coast Federal and attainment of age 60, after
completion of 25 years of service with Coast Federal and attainment of age 55,
or, regardless of the number of years of service, after attaining age 65.
Certain payments may also be made in the case of death or disability (as defined
therein) of the participant. If a participant's employment terminates prior to
eligibility for his or her benefit other than by reason of death or disability
or in the context of a change in control as set forth in the next sentence, such
participant forfeits his or her benefit under the Supplemental Plan, with the
exception of Messrs. Martin, Hunt, Boyle, Raiden and Barritt to whom such
benefit would be paid upon attainment of age 65 in such case. If a participant
is terminated by Coast Federal without cause (as defined therein) or voluntarily
resigns from Coast Federal for good reason (as defined therein) before the third
anniversary of a change in control of Coast Federal, Coast Federal will be
obligated to commence paying in the next calendar month following such change in
control such participant's benefit in an annuity or lump sum as chosen by the
participant (subject to certain reductions). The benefit payable to participants
in the case of a change in control may be reduced in order to avoid the
triggering of golden parachute penalties under Section 280G of the Code, with
the exception of Messrs.
Martin, Hunt, Boyle, Raiden and Barritt.

        Deferred Compensation Plan. Coast Federal currently has an unfunded
deferred compensation plan (the "Deferred Compensation Plan") to allow certain
designated officers and directors of Coast Federal to defer for receipt in a
later year a portion of his or her annual compensation. Each participant who
elects to defer compensation must also elect a time and manner for its receipt
in a later year in accordance with the terms of the Deferred Compensation Plan
and generally will not be permitted to receive such deferred compensation prior
to the elected time. Any such deferred compensation will be credited to an
account on behalf of a participant and will be credited with earnings based upon
an interest rate determined by Coast Federal or, if permitted, deemed
investments chosen by the participant. In the event a participant's employment
with Coast Federal is terminated by Coast Federal following a change in control
of Coast Federal or the participant voluntarily terminates employment due to a
material reduction in responsibilities or compensation benefits following a
change in control of Coast Federal, Coast Federal must pay the participant a
lump sum distribution of such participant's account in January of the year
following the year of termination, unless the participant has requested
otherwise in writing at least one year prior to such change in control.

        COAST EXECUTIVES AND THE CPR TRUST.

        Four senior Coast executives (Messrs. Martin, Hunt, Raiden and Barritt)
with knowledge of the facts underlying the Litigation will be the Litigation
Trustees of the CPR Trust. Mr. Martin (currently Chairman of the Board and Chief
Executive Officers of Coast and Coast Federal), Mr. Hunt (currently President
and Chief Operating Officer of Coast and Coast Federal) and Mr. Barritt
(currently Senior Executive Vice President and Chief Financial Officer of Coast
and Coast Federal) were officers of Coast and Coast Federal both at the time
that Coast Federal entered into the agreement with the federal government to
treat certain amounts as a permanent addition to Coast Federal's regulatory
capital in connection with Coast Federal's acquisition of Central Savings and
Loan Association, and also at the time of the alleged breach of




                                      -43-
<PAGE>   51

that agreement by the federal government that gave rise to the claims underlying
the Litigation. Mr. Martin, Mr. Hunt and Mr. Barritt, together with Mr. Raiden
(currently Senior Executive Vice President and General Counsel of Coast and
Coast Federal, and who joined Coast soon after the alleged breach of the
agreement by the federal government), have been involved in the prosecution of
the Litigation to date. The CPR Trust Agreement will provide that, as Litigation
Trustees, they will have sole and exclusive control of Coast Federal's (or its
successor's) pursuit of the Litigation. Litigation Trustees will not be
permitted to hold any other full-time employment during the term of their tenure
as Litigation Trustees prior to the receipt of the Litigation Proceeds by the
Ahmanson Group. Each of the initial Litigation Trustees will, as a condition of
his continuation as a Litigation Trustee, be obligated to retain at least 50% of
the CPR Certificates received in the CPR Certificate Distribution and the Merger
and upon exercise of Replacement Options, until the Litigation Proceeds are
received by the Ahmanson Group. Transfers by a Litigation Trustee to his family
members or to any trust created for the benefit of his family will be included
in such 50% calculation for so long as such transferees retain the CPR
Certificates. 

        The CPR Trust Agreement will provide that, as compensation, the CPR
Trust will pay each Litigation Trustee, during the term of his service as a
Litigation Trustee, fees of $400,000 per year for five years (except that if the
Litigation is sooner terminated, the remainder of such fees (but in no event
with respect to a period longer than two years after the year in which such
termination occurs) will be accelerated upon final resolution of the Litigation
and receipt by the Ahmanson Group of the Litigation Proceeds), plus
reimbursement of all reasonable out-of-pocket expenses. If the services of the
Litigation Trustees continue to be necessary after the initial five-year period
or such receipt of Litigation Proceeds, the Litigation Trustees will be entitled
to a fee of $200 per hour until termination of the CPR Trust.

        The CPR Trust Agreement will provide that the Litigation Trustees will
have no liability to Ahmanson, Coast or CPR Certificate holders unless it is
established in a final judicial determination by clear and convincing evidence
that any decision or action was undertaken with deliberate intent to injure the
CPR Certificate holders or with reckless disregard for the best interests of
such holders, and, in any event, any liability will be limited to actual,
proximate, quantifiable damages. The CPR Trust will be obligated to indemnify
and advance expenses to, without requirement of bond or other security, each
Litigation Trustee against any and all losses, claims, costs, expenses and
liabilities arising out of or relating to, among other things, the Litigation
and the performance by the Litigation Trustees of their duties as Litigation
Trustees, except that if CPR Certificate holders meet the burden of establishing
in a final judicial determination by clear and convincing evidence that such
losses, claims, costs, expenses or liabilities arose as the result of actions or
decisions undertaken with deliberate intent to injure the CPR Certificate
holders or with reckless disregard for the best interests of such holders by
such Litigation Trustees, no indemnification shall apply. The CPR Trust will be
obligated to obtain liability insurance to cover its indemnification obligations
to the Litigation Trustees and others and any other liabilities of the
Litigation Trustees.

CONDITIONS TO CONSUMMATION

        The obligations of Coast and Ahmanson to consummate the Merger are
subject to the satisfaction or written waiver of the following conditions: (a)
the Transaction Proposal shall have been duly adopted by the requisite vote of
the stockholders of Coast; (b) all regulatory approvals required to consummate
the transactions contemplated by the Merger Agreement shall have been obtained
and shall remain in full force and effect and all statutory waiting periods in
respect thereof shall have expired and no such approvals shall contain any
conditions, restrictions or requirements which would reasonably be expected to
(i) following the Effective Time, have a Material Adverse Effect (as defined in
the Merger Agreement) on Ahmanson and its subsidiaries taken as a whole or (ii)
reduce the benefits of the Merger to such a degree that Ahmanson would not have
entered into the Merger Agreement had such conditions, restrictions or
requirements been known at the date of the Merger Agreement; (c) no
administrative agency or commission or other federal, state or local
governmental authority or instrumentality shall have taken any action
prohibiting the consummation of the transactions contemplated by the Merger
Agreement; (d) the Registration Statements shall have become effective and shall

have been duly qualified under the Trust Indenture Act of 1939, as amended, and
the rules and regulations thereunder; (e) the shares of Ahmanson Common Stock to
be issued in the Merger shall have been approved for listing on the NYSE,

                                      -44-
<PAGE>   52

to certain tax matters; (g) Ahmanson shall have received an opinion of Sullivan
& Cromwell, special counsel to Ahmanson, as to certain tax matters; (h) the
other party's representations and warranties shall remain accurate and each
party shall have performed in all material respects all of the obligations
required to be performed by it pursuant to the Merger Agreement, and shall have
delivered certificates confirming satisfaction of the foregoing requirements;
(i) each party shall have received a letter of the other party's independent
accountants as to certain financial information of the other party; (j) in the
case of Coast, Ahmanson shall have executed and delivered the Commitment and
made the transfer to the CPR Trust with respect to the Expense Fund (as defined
herein); (k) in the case of Ahmanson, holders of no more than 5% of the
outstanding shares of Coast Common Stock shall have given notice that their
shares of Coast Common Stock be treated as Dissenters' Shares; and (l) in the
case of Ahmanson, Coast shall have established the CPR Trust and shall have
caused the CPR Trust to issue the CPR Certificates to Coast and shall have
distributed the CPR Certificates to the stockholders of Coast as required by the
Merger Agreement.

        The conditions to consummation of the Merger may generally be waived, in
whole or in part, to the extent permissible under applicable law, by the party
for whose benefit the condition has been imposed, without the approval of the
Coast stockholders. See "--Amendment and Waiver."

        No assurances can be provided as to when or if all of the conditions
precedent to the Merger can or will be satisfied or waived by the appropriate
party. As of the date of this Proxy Statement/Prospectus, Ahmanson and Coast
have no reason to believe that any of the conditions set forth above will not be
satisfied.

REGULATORY APPROVALS

        The Merger is subject to the approval of the OTS, under the Home Owners'
Loan Act and related OTS regulations. Ahmanson filed an application for such
approval on November 3, 1997. Approval requires consideration by the OTS of
various factors, including assessments of the competitive effect of the
contemplated transaction, the managerial and financial resources and future
prospects of the resulting institution and the effect of the contemplated
transaction on the convenience and needs of the communities to be served. These
regulatory considerations also include, among other things, an assessment of
compliance with the Community Reinvestment Act of 1977 (the "CRA"). Each of Home
Savings and Coast Federal currently has an "outstanding" CRA rating. The
regulations of the OTS require publication of notice of, and an opportunity for
public comment with respect to, the application filed in connection with the
Merger. The public comment period with respect to the application will expire on
_______, 1997.

        The Merger may not be consummated for a period of 15 to 30 days
following the OTS's approval (the precise length of the period to be determined
by the OTS with the concurrence of the Attorney General of the United States),
during which time the United States Department of Justice could challenge the
Merger on antitrust grounds. The commencement of an antitrust action would stay
the effectiveness of any approval granted by the OTS unless a court specifically
ordered otherwise.

        The Merger Agreement provides that the obligation of each of Ahmanson
and Coast to consummate the Merger is conditioned upon, among other things, (i)
the receipt of all requisite regulatory approvals, including the approval of the
OTS, (ii) the termination or expiration of all statutory waiting periods in
respect thereof and (iii) no such approvals containing conditions, restrictions
or requirements which would reasonably be expected to, after the Effective Time,
have a Material Adverse Effect on Ahmanson and its subsidiaries taken as a whole
or reduce the benefits of the transactions contemplated in the Merger Agreement
to such a degree that Ahmanson would not have entered into the Merger Agreement
had such been known at the date of the Merger Agreement.

        THE MERGER CANNOT PROCEED IN THE ABSENCE OF THE REQUISITE REGULATORY
APPROVALS. THERE CAN BE NO ASSURANCES THAT ALL SUCH REGULATORY APPROVALS WILL BE
OBTAINED OR AS TO THE DATES OF SUCH APPROVALS. THERE CAN ALSO BE NO ASSURANCE
THAT SUCH APPROVALS WILL NOT CONTAIN A CONDITION, RESTRICTION OR REQUIREMENT
THAT CAUSES SUCH APPROVALS TO FAIL TO SATISFY THE CONDITIONS SET FORTH IN THE
MERGER AGREEMENT. SEE "--THE EFFECTIVE TIME," "--CONDITIONS TO CONSUMMATION" AND
"--AMENDMENT AND WAIVER."

<PAGE>   53

AMENDMENT AND WAIVER

        To the extent permitted by law, Coast and Ahmanson may amend the Merger
Agreement by written agreement at any time prior to the Effective Time. Prior to
the Effective Time, either Coast or Ahmanson may waive any default in the
performance of any term of the Merger Agreement by the other party, may waive or
extend the time for the fulfillment by the other party of any of its obligations
under the Merger Agreement, and may waive any of the conditions precedent to the
obligations of such party under the Merger Agreement, except any condition that,
if not satisfied, would result in the violation of an applicable law or
governmental regulation.

TERMINATION; TERMINATION FEE

        The Merger Agreement may be terminated, and the Merger abandoned, at any
time prior to the Effective Time by mutual consent of the boards of directors of
Coast and Ahmanson. In addition, the Merger Agreement may be terminated, and the
Merger abandoned, prior to the Effective Time by (a) either Ahmanson or Coast
if: (i) the other party breaches, and does not timely cure any breach of, a
representation, warranty, covenant or other agreement contained in the Merger
Agreement and such breach, individually or in the aggregate, would be reasonably
likely to have a Material Adverse Effect (as defined in the Merger Agreement) on
the non-breaching party; (ii) any consent or approval of certain regulatory
authorities is denied by final nonappealable action of such authority or the
Coast stockholders fail to approve the Transaction Proposal; or (iii) the Merger
has not been consummated by June 30, 1998; or (b) by Ahmanson, if the Coast
Board has failed to recommend approval of the Merger, has withdrawn such
recommendation or has modified or changed such recommendation in a manner
adverse to Ahmanson.

        Coast would be required to pay Ahmanson a Termination Fee of $35 million
if (a) the Merger Agreement is terminated (i) by Ahmanson due to a breach by
Coast of any representation, warranty or covenant contained in the Merger
Agreement, to a failure by the Coast Board to recommend approval of the Merger
to Coast stockholders, or to a withdrawal, modification, or change of such
recommendation in a manner adverse in any respect to the interests of Ahmanson,
or (ii) by Coast because the Coast stockholders vote to reject the Merger, if in
either case an acquisition proposal by a third party with respect to Coast or
any of its subsidiaries exists at the time the event giving rise to such
termination right occurs; and (b) a definitive agreement with respect to an
acquisition proposal by a third party is entered into by Coast or any of its
subsidiaries within 12 months of such termination.

        AHMANSON.

        Ahmanson has agreed in the Merger Agreement, unless the prior written
consent of Coast is obtained, and except as otherwise contemplated by the Merger
Agreement, not to:

        (a) make, declare, pay or set aside for payment any dividends other than
quarterly dividends in an amount, and with record and payment dates, consistent
with past practice (provided that Ahmanson may raise its regular quarterly
dividend rate by an amount not exceeding 20%);

        (b) (i) take any action while knowing that such action would, or is
reasonably likely to, prevent or impede the Merger from qualifying as a
reorganization within the meaning of Section 368 of the Code; (ii) repurchase
any Ahmanson Common Stock or Ahmanson Preferred Stock (as defined herein) such
that an Ahmanson stockholder vote would be required for consummation of the
Merger or which would have the effect of a recapitalization of Ahmanson or at
prices reflecting a significant premium to the prices at which the Ahmanson
Common Stock is then trading; or (iii) take any action that is intended or is
known to be reasonably likely to result in (A) any of its representations and
warranties set forth in the Merger Agreement being or becoming untrue in any
material respect at any time at or prior to the Effective Time, (B) any of the
conditions to the Merger set forth under "--Conditions to Consummation" not
being satisfied or (C) a material violation of any provision of the Merger
Agreement except, in each case, as may be required by applicable law or
regulation; or

        (c) agree or commit to do any of the foregoing.

EXPENSES AND FEES

        The Merger Agreement provides that each party shall be responsible for
all expenses incurred by it in connection with the Merger Agreement and the
transactions contemplated by the Merger Agreement, except that Ahmanson and
Coast have agreed to share equally all Commission filing fees and all printing
expenses payable in connection with the Registration Statement[s] and this Proxy
Statement/Prospectus. In the event of a termination of the Merger Agreement
under certain circumstances, Coast would be obligated to pay Ahmanson a fee of
$35 million. See "--Termination; Termination Fee."

ACCOUNTING TREATMENT

        Upon consummation of the Merger, Ahmanson will account for the
acquisition of Coast using the purchase method of accounting. Accordingly, the
consideration to be paid in the Merger will be allocated to assets acquired and




                                      -48-
<PAGE>   56

liabilities assumed based on their estimated fair values at the Effective Date.
Income (or loss) of Coast prior to the Effective Date will not be included in
income of the combined company.

STOCK EXCHANGE LISTING OF AHMANSON COMMON STOCK

        Ahmanson has agreed to use its reasonable best efforts to list, prior to
the Effective Date, on the NYSE, subject to official notice of issuance, the
shares of Ahmanson Common Stock to be issued to the holders of Coast Common
Stock in the Merger, and such listing is a condition to consummation of the
Merger.

RESALES OF AHMANSON COMMON STOCK

        The shares of Ahmanson Common Stock issued in connection with the Merger
will be freely transferable under the Securities Act, except for shares issued
to any stockholder who may be deemed to be an "affiliate" (generally including,
without limitation, directors, certain executive officers, and beneficial owners
of 10% or more of any class of capital stock) of Coast for purposes of Rule 145
under the Securities Act as of the date of the Special Meeting. Such affiliates
may not sell their shares of Ahmanson Common Stock acquired in connection with
the Merger except pursuant to an effective registration statement under the
Securities Act or other applicable exemption from the registration requirements
of the Securities Act.

        Coast has agreed in the Merger Agreement to use its reasonable best
efforts to cause each person who may be deemed to be an "affiliate" of Coast to
execute and deliver to Ahmanson an agreement pursuant to which such person
agrees, among other things, not to offer to sell, transfer or otherwise dispose
of any of the shares of Ahmanson Common Stock distributed to them pursuant to
the Merger except in compliance with Rule 145 under the Securities Act, or in a
transaction that, in the opinion of counsel reasonably satisfactory to Ahmanson,
is otherwise exempt from the registration requirements of the Securities Act, or
in an offering which is registered under the Securities Act. Ahmanson may place
restrictive legends on certificates representing Ahmanson Common Stock issued to
all persons who are deemed to be "affiliates" of Coast under Rule 145. This
Proxy Statement/Prospectus does not cover resales of Ahmanson Common Stock
received by any person who may be deemed to be an affiliate of Coast.

ACQUISITION PROPOSALS

        Coast has agreed in the Merger Agreement that it shall not, and shall
cause its subsidiaries and its and its subsidiaries' officers, directors,
agents, advisors and affiliates not to, solicit or encourage inquiries or
proposals with respect to, or engage in any negotiations concerning, or provide
any confidential information to, or have any discussions with, any person
relating to, any tender or exchange offer, proposal for a merger, consolidation
or other business combination involving Coast or any of its subsidiaries or any
proposal or offer to acquire in any manner a substantial equity interest in, or
a substantial portion of the assets or deposits of, Coast or any of its
subsidiaries (an "Acquisition Proposal"), or waive any provision of or amend the
terms of the Coast Rights Plan in respect of an Acquisition Proposal; provided,
however, that the Merger Agreement does not (a) require the Coast Board to
recommend stockholder approval of the Merger following an Acquisition Proposal,
(b) prevent Coast or the Coast Board from (i) engaging in any discussions or
negotiations with, or providing any information to, any person in response to an
unsolicited bona fide written Acquisition Proposal by any such person or (ii)
recommending such an unsolicited bona fide written Acquisition Proposal to the
holders of Coast Common Stock or (c) prevent Coast from waiving any provision of
or amending the terms of the Coast Rights Plan in respect of an Acquisition
Proposal, if and only if, with respect to the actions described in clause (a),
(b) or (c), as applicable, (A) the Coast Board concludes in good faith that the
Acquisition Proposal, if consummated, would result in a transaction more
favorable to holders of Coast Common Stock than the transaction contemplated by
the Merger Agreement, (B) the Coast Board determines in good faith based upon
the advice of outside counsel that such action is legally necessary for it to
act in a manner consistent with its fiduciary duties under applicable law; and
(C) prior to providing any information or data to any person or entering into
discussions or negotiations with any person, the Coast Board notifies Ahmanson
immediately of such inquiries, proposals or offers received by, any such
information requested from, or any such discussions or negotiations sought to be
initiated or continued with Coast or any subsidiary of Coast. Coast has agreed
promptly (within 24 hours) to advise Ahmanson following the receipt by Coast of
any Acquisition Proposal and the substance thereof (including the identity of
the person making such Acquisition




                                      -49-
<PAGE>   57

Proposal), and to advise Ahmanson of any developments with respect to such
Acquisition Proposal immediately upon the occurrence thereof.

EARNINGS ESTIMATES

        In connection with the announcement of the Merger, Ahmanson announced
that it estimated that the Merger will be accretive to Ahmanson's reported
earnings per share in 1998, 1999 and 2000 by 2%, 4% and 6%, respectively, and to
Ahmanson's cash earnings per share (i.e., reported earnings before amortization
of intangibles) in 1998, 1999 and 2000 by 6%, 10% and 10%, respectively. This
estimate includes Ahmanson's current estimates of annual cost savings equal to
$75 million pre-tax (substantially all of which Ahmanson expects to be able to
achieve within 12 months of the Effective Date) and no revenue enhancements.
Ahmanson estimates it will incur a $75 million pre-tax charge in connection with
the Merger. See "Cautionary Statement Regarding Forward-Looking Statements" on
page 4 hereof.

                                APPRAISAL RIGHTS

        Record holders of Coast Common Stock are entitled to appraisal rights
under Section 262 of the DGCL ("Section 262"). The following discussion
represents a summary of the material provisions of Section 262. For additional
information, reference is made to the full text of Section 262, which is
reprinted in its entirety as Appendix E to this Proxy Statement/Prospectus. A
person having a beneficial interest in shares of Coast Common Stock held of
record in the name of another person, such as a broker or nominee, must act
promptly to cause the record holder to follow the steps summarized below
properly and in a timely manner to perfect the appraisal rights provided under
Section 262.

        Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the Special Meeting, not less than 20
days prior to the meeting, a constituent corporation must notify each of the
holders of its stock for which appraisal rights are available that such
appraisal rights are available and include in each such notice a copy of Section
262. THIS PROXY STATEMENT/PROSPECTUS SHALL CONSTITUTE SUCH NOTICE TO THE RECORD
HOLDERS OF COAST COMMON STOCK. ANY SUCH STOCKHOLDER WHO WISHES TO EXERCISE SUCH
APPRAISAL RIGHTS SHOULD REVIEW THE FOLLOWING DISCUSSION AND APPENDIX E
CAREFULLY, BECAUSE FAILURE TO TIMELY AND PROPERLY COMPLY WITH THE PROCEDURES
SPECIFIED WILL RESULT IN THE LOSS OF APPRAISAL RIGHTS UNDER THE DGCL. Moreover,
because of the complexities of the procedures for exercising the right to seek
appraisal of the Coast Common Stock, Coast recommends that Coast stockholders
who consider exercising such rights seek the advice of counsel.

        Under the DGCL, a record holder of shares of Coast Common Stock who
makes the demand described below with respect to such shares, who continuously
is the record holder of such shares through the Effective Time, who otherwise
complies with the statutory requirements set forth in Section 262 and who
neither votes in favor of approval of the Transaction Proposal nor consents
thereto in writing will be entitled to have their shares of Coast Common Stock
appraised by the Delaware Court of Chancery and to receive payment of the "fair
value" of such shares as described below. Accordingly, in connection with any
appraisal proceeding, the "fair value" of shares of Coast Common Stock is to be
determined as of immediately prior to the CPR Certificate Distribution and the
Merger. Such holders are, in such circumstances, entitled to appraisal rights
because they hold stock of a constituent corporation to the Merger and may be
required by the Merger Agreement to accept consideration in the Merger, at least
in part, other than in the form of Ahmanson Common Stock. Specifically,
Ahmanson's entering into of the Commitment constitutes part of the Merger
Consideration to the stockholders of Coast. Since holders of shares of Coast
Common Stock wishing to exercise appraisal rights must not vote in favor of
approval of the Transaction Proposal, such holders should not deliver unmarked
proxies (i.e., proxies without instructions) to Coast as such proxies will be
voted FOR such approval.

        A holder of shares of Coast Common Stock wishing to exercise his or her
appraisal rights must deliver to the Secretary of Coast, before the vote on the
Merger Agreement at the Special Meeting, a written demand for appraisal of his
or her shares of Coast Common Stock. Merely voting or delivering a proxy
directing a vote against approval of the Transaction Proposal will not
constitute a demand for appraisal. A written demand is essential. Such written
demand must reasonably inform Coast of the identity of the holder and that such
holder intends thereby to demand appraisal of the holder's shares. All written
demands for appraisal of Coast Common Stock should be sent or delivered to Coast
Savings Financial, Inc., 1000 Wilshire Boulevard, Los Angeles, California 90017,
Attn: Corporate Secretary. In addition, a holder of shares of Coast Common Stock
wishing to exercise his or her appraisal rights must hold such shares of record
on the date the written demand for appraisal is made and must hold such shares
continuously through the Effective Time. A demand for appraisal should be
executed by or on behalf of the stockholder of record, fully and correctly, as
such stockholder's name appears on such stockholder's stock certificates, should
specify the stockholder's name and mailing address, the number of shares of
Coast Common Stock owned and that such stockholder intends thereby to demand
appraisal of such stockholder's stock. However, such demand will be sufficient
if it reasonably informs Coast of the stockholder's identity and intent to
demand the appraisal of his shares. If the shares are owned of record in a
fiduciary capacity, such as by a trustee, guardian or custodian, execution of
the demand should be made in that capacity, and if the shares of the Coast
Common Stock are owned of record by more than one person, as in a joint tenancy
or tenancy in common, the demand should be executed by or on behalf of all joint
owners. An authorized agent, including one or more joint owners, may execute a
demand for appraisal on behalf of a holder of record; however, the agent must
identify the record owner or owners and expressly disclose the fact that in
executing the demand for appraisal, the agent is agent for




                                      -51-
<PAGE>   59

such owner or owners. A record holder (such as a broker) who holds shares of
Coast Common Stock as a nominee for several beneficial owners may exercise
appraisal rights with respect to the shares of Coast Common Stock held for one
or more beneficial owners while not exercising such rights with respect to the
shares of Coast Common Stock held for other beneficial owners; in such case, the
written demand should set forth the number of shares as to which appraisal is
sought and where no number of shares is expressly mentioned, the demand will be
presumed to cover all shares of Coast Common Stock held in the name of the
record owner. Stockholders who hold their shares of Coast Common Stock in
brokerage accounts or other nominee forms and who wish to exercise appraisal
rights must take all necessary steps in order that a demand for appraisal is
made by the record holder of such shares and are urged to consult with their
brokers to determine the appropriate procedures for the making of a demand for
appraisal by the record holder.

        Within ten days after the Effective Time of the Merger, Ahmanson, as the
surviving corporation, must send a notice as to the effectiveness of the Merger
to each person who has satisfied the appropriate provisions of Section 262 and
who is entitled to appraisal rights under Section 262. Within 120 days after the
Effective Time, any holder of record of shares of Coast Common Stock who has
complied with the requirements for exercise of appraisal rights will be
entitled, upon written request, to receive from the surviving corporation, a
statement setting forth (a) the aggregate number of shares of Coast Common Stock
not voted in favor of the Merger Agreement and with respect to which demands for
appraisal have been received and (b) the aggregate number of holders of such
shares. Any such statement must be mailed within ten days after a written
request therefor has been received by Ahmanson, as the surviving corporation.

        Within 120 days after the Effective Time, but not thereafter, Ahmanson,
as the surviving corporation, or any holder of shares of Coast Common Stock who
has complied with the foregoing procedures and who is entitled to appraisal
rights under Section 262 may file a petition in the Delaware Court of Chancery
demanding a determination of the "fair value" of such shares. Ahmanson, as the
surviving corporation, is not under any obligation to file a petition with
respect to the appraisal of the "fair value" of the shares of Coast Common Stock
and neither Ahmanson nor Coast presently intends that Ahmanson, as the surviving
corporation, file such a petition. Accordingly, it is the obligation of the
stockholders to initiate all necessary action to perfect their appraisal rights
within the time prescribed in Section 262. A holder of shares of Coast Common
Stock will fail to perfect, or effectively lose, his or her right to appraisal
if no petition for appraisal of shares of Coast Common Stock is filed within 120
days after the Effective Time.

        If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Court of Chancery will determine the holders of shares of
Coast Common Stock entitled to appraisal rights and will appraise the "fair
value" of the shares of Coast Common Stock, exclusive of any element of value
arising from the accomplishment or expectation of the Merger. Holders
considering seeking appraisal should be aware that the "fair value" of their
shares of Coast Common Stock as determined under Section 262 could be more than,
the same as, or less than the value of the merger consideration they would
receive if they did not seek appraisal. The Delaware Supreme Court has stated
that "proof of value by any techniques or methods which are generally considered
acceptable in the financial community and otherwise admissible in court" should
be considered in the appraisal proceedings. The Delaware Supreme Court has also
stated that, in making this determination of fair value, the court must consider
market value, asset value, dividends, earnings prospects, the nature of the
enterprise and any other facts which could be ascertained as of the date of the
merger that throw any light on future prospects of the merged corporation. The
Delaware Supreme Court has also stated that "elements of future value, including
the nature of the enterprise, which are known or susceptible of proof as of the
date of the merger and not the product of speculation, may be considered." In
addition, Delaware courts have decided that the statutory appraisal remedy,
depending on factual circumstances, may or may not be a dissenter's exclusive
remedy.

        The Delaware Court of Chancery will determine the amount of interest, if
any, to be paid upon the amounts to be received by persons whose shares of Coast
Common Stock have been appraised. The costs of the action may be determined by
such court and taxed upon the parties as the court deems equitable. The Delaware
Court of Chancery may also order that all or a portion of the expenses incurred
by any holder of shares of Coast Common Stock in connection with an appraisal,
including, without limitation, reasonable attorneys' fees and the fees and
expenses of experts utilized in the appraisal proceeding, be charged pro rata
against the value of all of the shares of Coast Common Stock entitled to
appraisal.

        A holder may withdraw his or her demand for appraisal by delivering to
Ahmanson, as the surviving corporation, a written withdrawal of his or her
demand for appraisal and acceptance of the Merger, except that any such attempt
to withdraw made more than 60 days after the Effective Time will require the
written approval of Ahmanson, as the surviving corporation. Failure to follow
the steps required by Section 262 for perfecting appraisal rights will result in
the loss of such rights.

        Any holder of shares of Coast Common Stock who has duly demanded an
appraisal in compliance with Section 262 will not, after the Effective Time, be
entitled to vote the shares of Coast Common Stock subject to such demand for any
purpose or be entitled to the payment of dividends or other distributions on
those shares (except dividends or other distributions payable to holders of
record of shares of Coast Common Stock as of a date prior to the Effective
Time).

        Each CPR Certificate distributed to each Coast stockholder provides that
it shall automatically be redeemed by Ahmanson, as the surviving corporation,
for $0.01 in cash immediately following the Merger if the holder of the share as
to which such CPR Certificate was issued has given notice of an intent to
exercise appraisal rights (if any). If any such Coast stockholder subsequently
withdraws, or fails to perfect, such appraisal demand, Ahmanson will deliver to
such holder CPR Certificates as to the number of Coast shares as to which such
appraisal demand was withdrawn or not perfected.

        It is a condition to the obligation of Ahmanson to consummate the Merger
that holders of no more than 5% of the outstanding shares of Coast Common Stock
shall have given notice that their shares of Coast Common Stock be treated as
Dissenters' Shares.

        FAILURE TO COMPLY STRICTLY WITH THE PROCEDURES SET FORTH IN SECTION 262
OF THE DGCL WILL RESULT IN THE LOSS OF A COAST STOCKHOLDER'S STATUTORY APPRAISAL
RIGHTS WITH RESPECT TO SHARES OF COAST COMMON STOCK. CONSEQUENTLY, ANY COAST
STOCKHOLDER WISHING TO EXERCISE APPRAISAL RIGHTS IS URGED TO CONSULT LEGAL
COUNSEL BEFORE ATTEMPTING TO EXERCISE SUCH RIGHTS.

                          AHMANSON AND COAST UNAUDITED
                    PRO FORMA COMBINED FINANCIAL INFORMATION

        The following unaudited pro forma combined financial statements were
prepared in connection with the proposed Merger (in which each outstanding share
of Coast Common Stock will be exchanged for 0.8082 of a share of Ahmanson Common
Stock, valued for purposes of accounting for the Merger at a price per share of
Ahmanson Common Stock of $56.45, based on the quoted market price of Ahmanson
Common Stock for a period of time shortly before and after the points in time
Ahmanson and Coast reached agreement on the purchase price and the terms and
conditions of the proposed Merger were publicly announced, and give effect to
the purchase accounting adjustments and other assumptions described in the
accompanying notes. The unaudited pro forma combined statement of financial
condition is based upon the condensed consolidated statements of financial
condition (unaudited) of Ahmanson and Coast as of September 30, 1997. The
unaudited pro forma combined statement of operations for the year ended December
31, 1996 is based upon the consolidated statements of operations of Ahmanson and
Coast for the year ended December 31, 1996. The unaudited pro forma combined
statement of operations for the nine months ended September 30, 1997 is based
upon the condensed consolidated statement of operations (unaudited) of Ahmanson
and Coast for the nine months ended September 30, 1997.

        The adjustments included in the unaudited pro forma combined financial
statements are subject to update as additional information becomes available. An
increase in the unallocated portion of the purchase price remaining after fair
value adjustments will result in a greater final allocation to goodwill, which
will increase amortization expense and will reduce tangible common equity. A
decrease in the unallocated portion of the purchase price remaining after fair
value adjustments will have the opposite effects. Any CPR Certificates received
by Ahmanson in connection with the Merger will be recorded at fair value and
will also reduce goodwill. Accordingly, the final pro forma combined amounts
will differ from those set forth in the unaudited pro forma combined financial
statements set forth herein.

        The information shown below should be read in conjunction with, and is
qualified in its entirety by reference to, the consolidated statement of
financial condition and consolidated statement of operations at and for the year
ended December 31, 1996 of Ahmanson and the consolidated statement of financial
condition and consolidated statement of operations at and for the year ended
December 31, 1996 of Coast. The pro forma data are presented for informational
purposes and are not necessarily indicative of the financial position or the
results of operations of the combined company that actually would have occurred
had the Merger been consummated as of the dates or at the beginning of the
periods presented. The pro forma amounts are also not necessarily indicative of
the future financial position or future results of operations of Ahmanson as the
surviving corporation. In particular, Ahmanson expects to achieve significant
operating cost savings as a result of the Merger. These cost savings, assuming
they are realized, would significantly reduce non-interest expense and increase
net income. Additionally, Ahmanson believes opportunities exist to enhance
certain revenues through the expansion of consumer and business loans, cash
management services, retail banking and investment sales generated through Coast
Federal branches. These revenue enhancements, if they are realized (which cannot
be assured as to amount or timing), would increase net interest income or fee
income and increase net income. No adjustment has been included in the pro forma
amounts for such cost savings or revenue enhancements.

                               AHMANSON AND COAST
                NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
                                   (UNAUDITED)


NOTE A:  BASIS OF PRESENTATION

        The unaudited pro forma combined statement of financial condition
combines the historical consolidated statements of financial condition
(unaudited) of Ahmanson and Coast as if the Merger had become effective on
September 30, 1997. The unaudited pro forma combined statement of operations for
the year ended December 31, 1996 combines the audited historical consolidated
statements of operations of Ahmanson and Coast as if the Merger had become
effective prior to January 1, 1996. The unaudited pro forma combined statement
of operations for the nine months ended September 30, 1997 combines the
historical condensed consolidated statements of operations (unaudited) of
Ahmanson and Coast as if the Merger had become effective prior to January 1,
1997. Certain items in the unaudited pro forma combined financial statements
related to Coast have been reclassified to conform to the Ahmanson presentation.

        The Merger will be accounted for as a purchase. Under this method of
accounting, assets and liabilities of Coast are adjusted to their estimated fair
value and combined with the recorded book values of the assets and liabilities
of Ahmanson. Applicable income tax effects of such adjustments are included as a
component of Ahmanson's net deferred tax asset with a corresponding offset to
goodwill.

        For purposes of the pro forma financial statements, estimates of the
fair value of Coast's assets and liabilities as of September 30, 1997 have been
combined with the recorded values of the assets and liabilities of Ahmanson.
Fair value adjustments are subject to update as additional information becomes
available.

        Following the Merger, Ahmanson intends to combine the operations of and,
subject to regulatory approvals, to merge Home Savings and Coast Federal as well
as certain other operations. Ahmanson expects to achieve significant operating
cost savings as a result of the Merger. These cost savings, assuming they are
realized, would significantly reduce non-interest expense and increase net
income. Additionally, Ahmanson believes opportunities exist to enhance certain
revenues through the expansion of consumer and business loans, cash management
services, retail banking and investment sales generated through Coast Federal
branches. These revenue enhancements, if they are realized (which cannot be
assured as to amount or timing), would increase net interest income or fee
income and increase net income. No adjustment has been included in the unaudited
pro forma combined financial statements for such cost savings or revenue
enhancements.

NOTE B:  PURCHASE PRICE

        The purchase price is based on exchanging 0.8082 of a share of Ahmanson
Common Stock for each outstanding share of Coast Common Stock. Shares issuable
upon the exercise of Coast Stock Options are not included in the number of
outstanding shares of Coast Common Stock on the assumption that all options will
become equivalent options to purchase Ahmanson Common Stock. In addition, the
number of the shares of Coast Common Stock used in calculating the total market
value of Ahmanson Common Stock to be issued in connection with the Merger
reflects an exchange of Ahmanson Common Stock for the outstanding shares of
Coast Common Stock, exclusive of Coast's common stock equivalents, which include
Coast Stock Options.

        The total market value of the Ahmanson Common Stock to be issued in
connection with the Merger is calculated as follows:

</TABLE>

        The shares of Ahmanson Common Stock to be issued to the stockholders of
Coast in connection with the proposed Merger have been valued at $56.45 per
share for purposes of the pro forma consolidated financial statements, based on
the quoted market price of Ahmanson Common Stock for a period of time shortly
before and after the points in time Ahmanson and Coast reached agreement on the
purchase price and the terms and conditions of the proposed Merger were publicly
announced.

        In addition to the total market value of the Ahmanson Common Stock to be
issued, the total purchase price will include other direct acquisition costs,
such as investment banking, legal, accounting and other professional fees;
printing and mailing costs; Commission filing fees and other miscellaneous
expenses. These costs, which are not expected to be material to the transaction
and are preliminarily expected to be approximately $10 million, have not been
included in the unaudited pro forma combined financial statements.

NOTE C:  RESTRUCTURING CHARGES

        Ahmanson's management estimates that approximately $75 million of costs
related to premises, severance and other restructuring charges will be incurred
in connection with the Merger; these estimates of costs are not yet based on
sufficient factual data so as to be included as adjustments to the unaudited pro
forma combined financial statements and are subject to change as additional
information becomes available. Of this amount, approximately $57 million of
costs relate to Coast's premises, employees and operations and will affect the
final amount of goodwill as of the consummation of the Merger, which goodwill
will be amortized as described in Note G below. The remaining estimated amount
of approximately $18 million of costs relates to Ahmanson's premises, employees
and operations, as well as all costs relating to systems conversions and other
indirect integration costs, and will be expensed, either upon consummation of
the Merger or as incurred. With respect to timing, it has been assumed that the
integration will be complete and that the costs referred to above will be
incurred not later than 12 months after the closing of the Merger.

        The estimated restructuring charges are expected to be incurred as set
forth in the following table:

</TABLE>

        Ahmanson's management estimates that the total severance costs in
connection with the Merger will be approximately $22 million. The estimate is
based on anticipated aggregate terminations, assumptions regarding severance
benefits on an aggregate basis and Ahmanson's experience in the integration of
mergers and does not reflect any information as to which employees will be
terminated as this information is not yet available.

        Ahmanson's estimate of $75 million in restructuring charges is in the
range of restructuring charges announced in connection with other similar
transactions and is based on the assumption that Ahmanson's experience in
integrating Coast's organization and operations will be similar to comparable
transactions in the past.

NOTE D:  ALLOCATION OF PURCHASE PRICE

        Certain matters are still pending that will have an effect on the
ultimate allocation of the purchase price. Accordingly, the allocation of the
purchase price has not been finalized and the portion of the purchase price
allocated to fair value adjustments, goodwill and the identifiable intangibles
(discussed below) is subject to change.

        Subject to the foregoing, the purchase price has been allocated as
described in the table below:

*    Goodwill due to the Merger will be amortized on a straight-line basis over

     straight-line basis over 10 years. Fair value adjustments will be amortized
     over the estimated remaining life of the related asset or liability.

        The incremental effect on net income of the purchase accounting
adjustments is estimated to be a net after-tax expense of approximately $18
million for the first and second 12-month periods subsequent to the Merger, and
approximately $21 million for the third, fourth and fifth 12-month periods
subsequent to the Merger. Amounts exclude amortization of existing goodwill of
Coast.

                      DESCRIPTION OF AHMANSON CAPITAL STOCK

AHMANSON COMMON STOCK

        Ahmanson is currently authorized to issue up to 220,000,000 shares of
Ahmanson Common Stock. As of September 30, 1997, there were 94,411,284 shares of
Ahmanson Common Stock issued and outstanding, outstanding options to purchase an
additional 3,430,419 shares of Ahmanson Common Stock and 11,814,238 shares of
Ahmanson Common Stock issuable upon conversion of the Ahmanson Series D
Preferred Stock (as defined herein).

        Since 1995, Ahmanson has been engaged in stock repurchase programs. For
a description of these programs see "--Repurchases of Ahmanson Common Stock."

        Holders of shares of Ahmanson Common Stock are entitled to one vote per
share for each share held.

        Subject to the rights of holders of shares of the Ahmanson Preferred
Stock (as described below), holders of shares of Ahmanson Common Stock are
entitled to receive such dividends as may be declared by the Ahmanson Board from
funds legally available therefor and, in the event of liquidation, from the net
assets of Ahmanson available for distribution to stockholders. Ahmanson may not
declare any dividends on the Ahmanson Common Stock (other than in shares of
Ahmanson Common Stock) unless full preferential amounts to which holders of
Ahmanson Preferred Stock are entitled have been paid or declared and set apart
for payment upon all outstanding shares of Ahmanson Preferred Stock. Ahmanson is
also subject to regulatory restrictions on the payment of dividends. See
"--Certain Regulatory Considerations."

        The holders of shares of Ahmanson Common Stock do not have preemptive
rights or preferential rights of subscription for any shares of Ahmanson Common
Stock or other securities of Ahmanson. Outstanding shares of Ahmanson Common
Stock are, and shares to be issued in the Merger will be, validly issued, fully
paid and nonassessable.

        The Ahmanson Common Stock is listed on the NYSE and the Pacific
Exchange. Application will be made to list the shares of Ahmanson Common Stock
to be issued in the Merger on the NYSE and the Pacific Exchange.

        For a description of the Ahmanson Rights Plan, see "Certain Differences
in the Rights of Ahmanson Stockholders and Coast Stockholders."

REPURCHASES OF AHMANSON COMMON STOCK

        Starting with the fourth quarter of 1995, Ahmanson has announced four
stock purchase programs. As of September 30, 1997, Ahmanson had purchased an
aggregate of 25.8 million shares of Ahmanson Common Stock at an average purchase
price of $31.68 per share. Of the $250 million authorized for the fourth stock
purchase program, $83.5 million remained available for purchases of Ahmanson
Common Stock at September 30, 1997. Ahmanson intends to continue its repurchase
program on generally the same basis as it has been conducted over the last two
years, although it has suspended its stock repurchase program from the date one
business day prior to the date of mailing of this Proxy Statement/Prospectus
until the consummation of the Merger.

        The source of funds for the repurchase plan will be primarily dividends
from Home Savings and other subsidiaries. Home Savings and Ahmanson's other
subsidiaries are projected to generate sufficient cash to provide the dividends
necessary to accomplish the contemplated repurchases while maintaining the
capital of Home Savings at a level sufficient to qualify as "well capitalized"
for regulatory purposes. Anticipated stock repurchases impact earnings per share
in two ways. Earnings per share are increased by reducing shares outstanding and
to a lesser extent earnings per share are decreased by lower net interest
margins.




                                      -63-

AHMANSON PREFERRED STOCK

        The certificate of incorporation of Ahmanson (the "Ahmanson Charter")
provides that Ahmanson is authorized to issue 10,000,000 shares of Ahmanson
Preferred Stock. The Ahmanson Preferred Stock may be issued from time to time in
one or more series and the Ahmanson Board is authorized to fix the voting
rights, designations, powers, preferences and the relative, participating,
optional or other rights, if any, and the qualifications, limitations or
restrictions thereof, of any wholly unissued series of Ahmanson Preferred Stock,
and to fix the number of shares constituting such series, and to increase or
decrease the number of shares of any such series, all without further action by
the holders of Ahmanson Common Stock.

        Because Ahmanson is a holding company, its rights, the rights of its
creditors and of its stockholders, including the holders of the shares of the
Ahmanson Preferred Stock, to participate in any distribution of the assets of
any subsidiary upon the latter's liquidation or recapitalization will be subject
to the prior claims of the subsidiary's creditors, except to the extent that
Ahmanson may itself be a creditor with recognized claims against the subsidiary.
The principal source of Ahmanson's revenues are dividends received from its
banking and other subsidiaries. Various statutory provisions limit the amount of
dividends its banking subsidiaries may pay without regulatory approval, and
various regulations can also restrict the payment of dividends. In addition,
federal statutes limit the ability of certain subsidiaries to make loans to
Ahmanson. See "--Certain Regulatory Considerations."

        The following is a brief description of certain terms of the outstanding
series of Ahmanson Preferred Stock. This description does not purport to be
complete and is qualified in its entirety by reference to the Ahmanson
Certificate, including the certificate of designations with respect to each such
series.

        The shares of Ahmanson Preferred Stock currently outstanding have
preference over Ahmanson Common Stock with respect to the payment of dividends
and the distribution of assets in the event of liquidation, winding up or
dissolution of Ahmanson. Each outstanding series ranks on a parity with the
other as to dividends and the distribution of assets upon liquidation, winding
up or dissolution.

        Generally, the holders of each series of Ahmanson Preferred Stock have
no voting rights. However, if the equivalent of six quarterly dividends payable
on a series of Ahmanson Preferred Stock are in default, the number of directors
of Ahmanson will be increased by two and the holders of such outstanding series
of Ahmanson Preferred Stock together with the holders of shares of every other
series of Ahmanson Preferred Stock similarly entitled to vote for the election
of two directors, acting together as a single class, will be entitled to elect
two of the authorized number of members of the Ahmanson Board at the next annual
meeting and at each subsequent annual meeting of stockholders, to serve until
all dividends accumulated have been fully paid for four consecutive quarterly
dividend periods, including the last preceding quarterly dividend period.
Ahmanson Depositary Shares representing each series of Ahmanson Preferred Stock
are listed on the NYSE.

        AHMANSON SERIES C PREFERRED STOCK.

        As of September 30, 1997, there were issued and outstanding 780,000
shares of Ahmanson 8.40% Preferred Stock, Series C, liquidation preference $250
per share (the "Ahmanson Series C Preferred Stock"), represented by 7,800,000
depositary shares, each representing a one-tenth interest in a share of Ahmanson
Series C Preferred Stock. The Ahmanson Series C Preferred Stock is redeemable at
the option of Ahmanson in whole or in part, on and after March 1, 1998 at a
price of $250 per share (equivalent to $25 per depositary share) plus accrued
and unpaid dividends to the redemption date.

        Dividends on the Ahmanson Series C Preferred Stock of $21.00 per share
(8.40% annualized rate) are cumulative and paid quarterly on the first day of
March, June, September and December (equivalent to $2.10 per annum per
depositary share).

        AHMANSON SERIES D PREFERRED STOCK.

        As of September 30, 1997, there were issued and outstanding 575,000
shares of 6% Cumulative Convertible Preferred Stock, Series D, liquidation
preference $500 per share (the "Ahmanson Series D Preferred Stock"), evidenced
by 5,750,000 depositary shares, each representing a one-tenth interest in a
share of Ahmanson Series D Preferred Stock. The Ahmanson Series D Preferred
Stock is redeemable at the option of Ahmanson, in whole or in part, on and after
September 1, 1998 at a price commencing at $515 per share and declining to $500
per share on September 1, 2003 and thereafter, plus accrued and unpaid dividends
to the redemption date.

        Dividends on the Ahmanson Series D Preferred Stock of $30 per share (6%
annualized rate) are cumulative and are paid quarterly on the first day of
March, June, September and December (equivalent to $3 per annum per depositary
share).

        The Ahmanson Series D Preferred Stock is convertible into Ahmanson
Common Stock, at the option of its holders, at a conversion rate of
approximately 20.5465 shares of Ahmanson Common Stock per share of Ahmanson
Series D Preferred Stock (equivalent to a conversion rate of 2.05465 shares of
Ahmanson Common Stock per depositary share) (subject to adjustments upon the
occurrence of certain events).


CERTAIN REGULATORY CONSIDERATIONS

        The following discussion addresses in general terms the regulatory
framework applicable to savings and loan holding companies and their
subsidiaries, and provides certain information relevant to Ahmanson. Regulation
of financial institutions such as Ahmanson and its subsidiaries is intended
primarily for the protection of depositors, the deposit insurance funds of the
Federal Deposit Insurance Corporation and the banking system as a whole, and
generally is not intended for the protection of stockholders or other investors.

        GENERAL.

        Ahmanson is a savings and loan holding company and, as such, is subject
to the OTS's regulations, examination, supervision and reporting requirements.
Home Savings is a federal savings bank and a member of the Federal Home Loan
Bank System, and its deposits are insured by the Federal Deposit Insurance
Corporation (the "FDIC"). It is subject to examination and supervision by the
OTS and the FDIC and to regulations governing such matters as capital standards,
mergers, establishment and closing of branch offices, subsidiary investments and
activities, and general investment authority.

        The descriptions of the statutes and regulations that are applicable to
Ahmanson and the effects thereof that are set forth below and elsewhere in this
document do not purport to be a complete description of such statutes and
regulations and their effects on Ahmanson or to identify every statute and
regulation that may apply to Ahmanson.

        SAVINGS AND LOAN HOLDING COMPANY REGULATIONS.

        Subject to certain limited exceptions, control of a savings association
or a savings and loan holding company may only be obtained with the approval (or
in the case of an acquisition of control by an individual, the absence of
disapproval) of the OTS, after a public comment and application review process.
Any company acquiring control of a savings association becomes a savings and
loan holding company, must register and file periodic reports with the OTS, and
is subject to OTS examination.

        AFFILIATE AND INSIDER TRANSACTIONS.

        Savings associations are subject to affiliate and insider transaction
rules under section 11 of the Home Owner's Loan Act; including those applicable
to member banks of the Federal Reserve System set forth in sections 23A, 23B,
22(g) and 22(h) of the Federal Reserve Act. These provisions, among other
things, prohibit or limit a savings association




                                      -65-
<PAGE>   73

from extending credit to, or entering into certain transactions with, its
affiliates (which generally include holding companies such as Ahmanson and any
company under common control with the savings association) and principal
stockholders, directors and executive officers of the savings association and
its affiliates.

        LIMITATIONS ON ACQUISITIONS.

        Ahmanson is generally prohibited, either directly or indirectly, from
acquiring control of any savings association or savings and loan holding company
absent prior approval by the OTS and from acquiring more than 5% of any class of
voting stock of any savings association or savings and loan holding company that
is not a subsidiary of Ahmanson.

        PAYMENT OF DIVIDENDS.

        Ahmanson's principal sources of funds are cash dividends paid to it by
Home Savings and other subsidiaries, investment income and borrowings. There are
restrictions on the ability of Home Savings to pay dividends to Ahmanson.
Savings association subsidiaries of savings and loan holding companies, such as
Home Savings, must notify the OTS of their intent to declare dividends at least
30 days before declaration. The OTS has the authority to preclude those
associates from declaring a dividend.

        OTS regulations impose limitations upon certain "capital distributions"
by savings associations, including dividends. The regulations establish a
three-tiered system of regulation, with the greatest flexibility being afforded
to institutions that meet or exceed the fully phased-in capital requirements.

        A savings institution that has capital immediately prior to, and on a
pro forma basis after giving effect to, a proposed capital distribution that is
at least equal to its fully phased-in capital requirements is considered a Tier
I institution ("Tier I Institution"). At September 30, 1997, Home Savings was a
Tier I Institution. A Tier I Institution may, without the approval of but with
prior notice to the OTS, make capital distributions during a calendar year up to
the greater of (1) 100% of its net income to date during the calendar year plus
the amount that would reduce the savings institution's "surplus capital ratio"
(the excess over its fully phased-in risk-based capital requirement) to one-half
of its surplus capital ratio at the beginning of the calendar year or (2) 75% of
the institution's net income over the most recent four quarter period. Any
additional capital distributions would require prior regulatory approval. The
OTS retains discretion to subject Tier I Institutions to the more stringent
capital distribution rules applicable to institutions with less capital if the
OTS determines that the institution is in need of more than normal supervision
and has provided the institution with notice to that effect. The OTS also
retains the authority to prohibit any capital distribution otherwise authorized
under the regulations if the OTS determines that the capital distribution would
constitute an unsafe or unsound practice.

        DEPOSIT INSURANCE.

        The FDIC administers two separate deposit insurance funds: the Bank
Insurance Fund (the "BIF"), which insures the deposits of institutions the
deposits of which were insured by the FDIC prior to the enactment of FIRREA, and
the Savings Association Insurance Fund (the "SAIF"), which insures the deposits
of institutions the deposits of which were insured by the Federal Savings and
Loan Insurance Corporation. Home Savings is a member of the BIF and currently is
obligated to pay deposit insurance assessments ratably to the SAIF and the BIF
based on 85% and 15% of total deposits, respectively. These percentages are
subject to change in the future based on future events.

        The FDIC has established a risk-based system for setting deposit
insurance assessments. Under the risk-based assessment system, an institution's
insurance assessments vary depending upon the level of capital the institution
holds and the degree to which it is the subject of supervisory concern to the
FDIC. During the first three quarters of 1996, the assessment rate for SAIF
deposits varied from 0.23% of covered deposits for well-capitalized institutions
that were deemed to have no more than a few minor weaknesses, to 0.31% of
covered deposits for less than adequately capitalized institutions that posed
substantial supervisory concern. The lowest assessment rate for BIF deposits was
$2,000 per institution per year. The assessment rate for both SAIF and BIF
deposits currently varies from zero to 0.27% of covered




                                      -66-
<PAGE>   74

deposits. Ahmanson paid $55.1 million in deposit insurance premiums to SAIF in
1996 compared to $79.9 million in 1995.

        Prior to enactment of the Deposit Insurance Funds Act of 1996 ("DIFA"),
the SAIF's three major obligations were to fund losses associated with the
failure of institutions with SAIF-insured deposits; to increase its reserves to
1.25% of insured deposits over a reasonable period of time; and to make interest
payments on debt incurred through the Financing Corporation to provide funds to
the former Federal Savings and Loan Insurance Corporation ("FICO Debt"). The
reserves of the SAIF were lower than the reserves of the BIF and the BIF did not
have an obligation to pay interest on the FICO Debt. Therefore, premiums
assessed on deposits insured by the SAIF were higher than premiums assessed on
deposits insured by the BIF. Such a premium structure provided FDIC-insured
institutions whose deposits were exclusively or primarily BIF-insured (such as
almost all commercial banks) certain competitive advantages over institutions
whose deposits were primarily SAIF-insured (such as Home Savings).

        DIFA required FDIC-insured depository institutions with SAIF-insured
deposits to pay a special assessment designed to increase the SAIF's reserves to
the required 1.25% of insured deposits. The amount of the special assessment
imposed on Home Savings was $243.9 million. DIFA also altered the obligation to
make interest payments on the FICO Debt so that assessments to collect the
necessary funds are imposed separately from the deposit insurance premium and
are now assessed on BIF-insured deposits, although at a lower rate, as well as
on SAIF-insured deposits. Because the reserves of both the SAIF and the BIF
equal or exceed the required minimum amount and FICO Debt assessments are
collected separately from deposit insurance assessments, deposit insurance
premiums are currently assessed on SAIF-insured and BIF-insured deposits
according to the same schedule.

        The FDIC may initiate a proceeding to terminate an institution's deposit
insurance after a 30-day notice period if, among other things, the institution
is in an unsafe and unsound condition to continue operations. It is the policy
of the FDIC to deem an insured institution to be in an unsafe and unsound
condition if its ratio of Tier I capital to total assets is less than 2%. Tier I
capital is similar to core capital but includes certain investments in and
extensions of credit to subsidiaries engaged in activities not permitted for
national banks. In addition, the FDIC has the power to suspend temporarily a
savings association's insurance on deposits received after the issuance of a
suspension order in the event that the savings association has no tangible
capital.

        FICO DEBT.

        Until December 31, 1999 or, if earlier, the date on which the last
savings association ceases to exist, the rate at which SAIF-insured deposits are
assessed with respect to FICO Debt interest payments will be five times the rate
at which BIF-insured deposits are assessed. Accordingly, institutions whose
deposits are exclusively or primarily BIF-insured (such as almost all commercial
banks) continue to have a competitive advantage over institutions whose deposits
are primarily SAIF-insured (such as Home Savings) although the extent of the
advantage is less than the deposit insurance premium advantage which existed
prior to the enactment of DIFA.

        CLASSIFICATION OF ASSETS.

        Federal regulations require savings associations to review their assets
on a regular basis and to classify them as "substandard," "doubtful" or "loss"
if warranted. Adequate valuation allowances for loan losses are required for
assets classified as substandard or doubtful. If an asset is classified as loss,
the institution must either establish a specific allowance for loss in the
amount classified as loss or charge off such amount. The institution's OTS
District Director has the authority to approve, disapprove or modify any asset
classification and any amounts established as allowances for loan losses.

        At present, certain general allowances may be included within regulatory
capital, while specific allowances may not. If an OTS examiner concludes that
additional assets should be classified or that the valuation allowances
established by the savings association are inadequate, the examiner may
determine, subject to internal review by the OTS, the need for and extent of
additional classification or any increase necessary in the savings association's
general or specific valuation allowances. An insured savings association is also
required to set aside adequate valuation allowances to the




                                      -67-
<PAGE>   75

extent that an affiliate possesses assets posing a risk to the institution and
to establish liabilities for off-balance sheet items, such as letters of credit
when loss becomes probable and estimable.

        CAPITAL REQUIREMENTS.

        The OTS has adopted capital regulations ("Capital Regulations") for
savings associations which establish three capital requirements--a core capital
requirement, a tangible capital requirement and a risk-based capital
requirement. The capital standards contained in the Capital Regulations
generally must be no less stringent than the capital standards applicable to
national banks. The Capital Regulations require savings associations to maintain
core capital of at least 3% of adjusted total assets, tangible capital of at
least 1.5% of adjusted total assets and total capital (being the sum of Core
Capital and Supplementary Capital) of at least 8% of risk-weighted assets. In
addition, institutions whose exposure to interest-rate risk is deemed to be
above normal will be required to deduct a portion of such exposure in
calculating their risk-based capital. The OTS may establish, on a case by case
basis, individual minimum capital requirements for savings associations that
vary from the requirements that would otherwise apply under the Capital
Regulations. The OTS has not established such individual minimum capital
requirements for Home Savings. Home Savings was in compliance with the Capital
Regulations at September 30, 1997. As of September 30, 1997, Home Savings' core
capital ratio was 5.89%. The Capital Regulations do not apply to Ahmanson, on a
consolidated or non-consolidated basis.

        Core capital generally includes common stockholders' equity (including
retained earnings but excluding the net unrealized gain or loss on securities
available for sale), noncumulative perpetual preferred stock and related surplus
and minority interests in the equity accounts of fully consolidated
subsidiaries. Intangible assets (other than a limited amount of mortgage
servicing rights and purchased credit card relationships) must be deducted from
core capital. Certain deferred tax assets also must be deducted.

        Tangible capital generally means core capital less any intangible assets
(other than a limited amount of mortgage servicing rights).

        Supplementary capital includes, among other things, certain types of
preferred stock and subordinated debt and, subject to certain limits, general
valuation loan and lease loss allowances. A savings association's supplementary
capital may be used to satisfy the risk-based capital requirement only to the
extent of that institution's core capital. Risk-weighted assets are determined
by multiplying each category of an institution's assets, including off balance
sheet equivalents, by a risk weight assigned by the OTS based on the credit risk
associated with those assets, and adding the resulting amounts. The risk weight
categories range from zero percent for cash and government securities to 100%
for assets that do not quality for preferential risk weighting as determined by
the OTS.

        The Capital Regulations treat asset sales with recourse as if they did
not occur, and generally require a savings association to maintain capital
against the entire amount of assets sold with recourse, even if recourse is for
less than the full amount. However, when assets are sold with recourse and the
amount of recourse is less than the risk-based capital requirement for such
assets, the assets are not included in risk-weighted assets and capital is
required to be maintained in an amount equal to such recourse amount. A savings
association's retention of the subordinated portion of a senior/subordinated
loan participation or package of loans is treated in the same manner as an asset
sale with recourse.

        The Capital Regulations contain special capital rules affecting savings
associations with certain kinds of subsidiaries. For purposes of determining
compliance with each of the capital standards, a savings association's
investments in and extensions of credit to subsidiaries engaged in activities
not permissible for a national bank are deducted from the savings association's
capital, net of reserves against such investment. Home Savings' REI subsidiary
is its only significant subsidiary engaged in activities not permissible for a
national bank. At September 30, 1997, Home Savings' investment in its REI
subsidiary aggregated $41.5 million, of which $38.3 million was required to be
deducted from Home Savings' capital.

        Each bank regulatory agency and the OTS is required to review its
capital standards every two years to determine whether those standards require
sufficient capital to facilitate prompt corrective action to prevent or minimize
loss to the deposit insurance funds.




                                      -68-

        PROMPT CORRECTIVE ACTION.

        Under OTS regulations which implement the "prompt corrective action"
system established in the Federal Deposit Insurance Act (the "FDIA"), an
FDIC-insured savings association is well capitalized if its ratio of total
capital to risk-weighted assets is 10% or more, its ratio of core capital to
risk weighted assets is 6% or more, its ratio of core capital to total assets is
5% or more and it is not subject to any written agreement, order or directive to
meet a specified capital level. At September 30, 1997 Home Savings met these
standards. An institution which is not well capitalized is "adequately
capitalized" if its ratio of total capital to risk-weighted assets is at least
8%, its ratio of core capital to risk-adjusted assets is at least 4% and its
ratio of core capital to total assets is at least 4% (3% if the institution
receives the highest rating on the OTS's CAMEL rating system). Any institution
which is not adequately capitalized is undercapitalized, significantly
undercapitalized or critically undercapitalized, depending upon its capital
ratios.

        An FDIC-insured savings association that is undercapitalized must submit
a capital restoration plan to the OTS. The plan may be approved only if the OTS
determines it is likely to succeed in restoring the institution's capital and
will not appreciably increase the risks to which the institution is exposed. The
association's performance under the plan must be guaranteed by any company which
controls the association, up to a maximum of 5% of the institution's assets. The
OTS may also require the association to take various actions deemed appropriate
to minimize potential losses to the deposit insurance fund. A significantly
undercapitalized association is subject to additional sanctions and a critically
undercapitalized association generally must be placed in receivership or
conservatorship.

        ENFORCEMENT AND PENALTIES.

        The FDIA contains extensive enforcement provisions applicable to all
FDIC-insured depository institutions, including savings associations and
"institution-affiliated parties," which includes, among others, directors,
officers, employees, agents and controlling stockholders of depository
institutions, including holding companies such as Ahmanson. An institution or
institution-affiliated party may be subject to a three tier penalty regime that
ranges from a maximum penalty of $5,000 per day for a simple violation to a
maximum penalty of $1 million per day for certain knowing violations including
the failure to submit or submission of incomplete, false or misleading reports.
An institution-affiliated party may also be subject to loss of voting rights
with respect to the stock of depository institutions.

        Whenever the OTS has reasonable cause to believe that the continuation
by a savings and loan holding company of any activity or of ownership or control
of any subsidiary not insured by the FDIC constitutes a serious risk to the
financial safety, soundness or stability of a subsidiary savings association and
is inconsistent with the sound operation of the savings association, the OTS may
order the holding company to terminate such activities or divest such
non-insured subsidiary. The OTS, without notice or opportunity for hearing, may
also (a) limit the payment of dividends by the savings association, (b) limit
transactions between the savings association and its holding company or other
affiliates and (c) limit any activity of the savings association which creates a
serious risk that the liabilities of the holding company and its affiliates may
be imposed upon the savings association.

        FDIA, as amended, requires the OTS to prescribe minimum operational and
managerial standards and standards for asset quality, earnings and stock
valuation for savings associations. Any savings association that fails to meet
the standards may be required to submit a plan for corrective action. If a
savings association fails to submit or implement an acceptable plan, the OTS may
require the association to take any action the OTS determines will best carry
out the purpose of prompt corrective action. The OTS and the bank regulatory
agencies have jointly published a regulation prescribing the required safety and
soundness standards. Home Savings believes that it is in compliance with the
regulation.

        LOANS AND INVESTMENTS.

        Aggregate loans to a single borrower are limited to specified
percentages of a savings association's capital, depending upon the existence and
type of any collateral. Aggregate loans secured by non-residential real property
are limited to a specified percentage of capital.




                                      -69-
<PAGE>   77

        Savings associations generally may not invest directly in equity
securities, non-investment grade securities or real estate. Indirect investments
in real estate are permitted through subsidiaries subject to limitations based,
generally, on the institution's capital ratios. Investments in subsidiaries, and
the activities conducted through subsidiaries, are subject to regulatory
restrictions.

        FHLB SYSTEM.

        The FHLBs provide a central credit facility for member institutions. As
a federal savings bank, Home Savings is required to be a member of the FHLB
System. Members of the FHLB System are required to own capital stock in an FHLB
at least equal to the greater of 1% of the member's outstanding home mortgage
loans and 5% of the member's advances from the FHLB. At September 30, 1997, Home
Savings' investment in FHLB stock was $405.6 million, substantially all of which
can not be withdrawn as long as Home Savings' real estate loan portfolio remains
at its current size.

        FEDERAL RESERVE SYSTEM.

        Home Savings is subject to various regulations promulgated by the
Federal Reserve Board, including, among others, Regulation B (Equal Credit
Opportunity), Regulation D (Reserves), Regulation E (Electronic Fund Transfers),
Regulation Z (Truth in Lending), Regulation CC (Availability of Funds) and
Regulation DD (Truth in Savings). As holders of loans secured by real property,
and as owners of real property, financial institutions, including Home Savings,
may be subject to potential liability under various statutes and regulations
applicable to property owners generally, including statutes and regulations
relating to the environmental condition of the property.

        LIQUIDITY.

        OTS regulations require a savings association to maintain, for each
calendar month, an average daily balance of liquid assets equal to at least 4%
of the average daily balance of its net withdrawable accounts plus short-term
borrowings during the preceding calendar month. The OTS may vary the required
percentage within a range of 4% to 10% and may also vary the definition of
liquid assets. Monetary penalties may be imposed for failure to meet liquidity
ratio requirements.

        COMMUNITY REINVESTMENT ACT.

        The CRA requires each savings association, as well as other depository
institutions, to identify the communities served by the institution's offices
and to identify the types of credit the institution is prepared to extend within
such communities. The CRA also requires the OTS to assess the performance of the
institution in meeting the credit needs of its community and to take such
assessments into consideration in reviewing applications for mergers,
acquisitions and other transactions. In connection with its assessment of a
savings association's CRA performance, the OTS will assign a rating of
"outstanding," "satisfactory," "needs to improve" or "substantial
noncompliance." Based on an examination conducted as of September 5, 1995, Home
Savings was rated "outstanding."

        QUALIFIED THRIFT LENDER.

        A savings association must invest at least 65% of its portfolio assets
in "qualified thrift investments" (each as defined by statute and OTS
regulations) on a monthly average basis in nine out of every 12 months on a
rolling 12-month "look back" basis. Home Savings was in compliance with this
requirement as of September 30, 1997 and would be in compliance on a pro forma
basis after giving effect to the Merger.

                  CERTAIN DIFFERENCES IN THE RIGHTS OF AHMANSON
                       STOCKHOLDERS AND COAST STOCKHOLDERS

        As a consequence of the Merger and the transactions contemplated
thereby, stockholders of Coast would become stockholders of Ahmanson. The
following is a summary of certain similarities and all material differences
between the rights of holders of shares of Coast Common Stock and the rights of
holders of Ahmanson Common Stock. Because each of Coast and Ahmanson is
organized under the laws of Delaware, these differences arise solely from
various provisions of the certificate of incorporation and by-laws of each of
Coast and Ahmanson, as well as from the Ahmanson Rights Agreement, dated as of
July 26, 1988, between Ahmanson and Union Bank, as rights agent (the "Ahmanson
Rights Plan") and the Coast Rights Agreement, dated as of August 25, 1989,
between Coast and Manufacturers Hanover Trust of California, as rights agent
(the "Coast Rights Plan").

        The following summary does not purport to be a complete statement of the
rights of stockholders under the Coast Charter, the Coast By-laws and the Coast
Rights Plan as compared with the rights of Ahmanson's stockholders under the
Ahmanson Charter, the by-laws of Ahmanson (the "Ahmanson By-Laws") and the
Ahmanson Rights Plan, or a complete description of the specific provisions
referred to herein. The summary is qualified in its entirety by reference to the
governing corporate instruments, including the aforementioned instruments, of
Coast and Ahmanson, copies of which have been filed as exhibits hereto or to
documents incorporated herein by reference.

MEETINGS OF STOCKHOLDERS

        Under Delaware law, special meetings of the stockholders may be called
by the board of directors or such other persons as may be authorized by the
certificate of incorporation or by-laws. The Coast Charter and By-Laws do not
authorize any other person to call a special meeting. The Ahmanson Charter and
By-Laws provide that a special meeting may also be called by a committee of the
Ahmanson Board which has been designated by the Ahmanson Board and authorized to
call a special meeting by a resolution of the Ahmanson Board or by the Ahmanson
By-Laws.

NUMBER AND ELECTION OF DIRECTORS

        Number of Directors. Under Delaware law, the number of directors shall
be fixed by or in the manner provided in the by-laws, unless the certificate of
incorporation fixes the number of directors, in which case a change in the
number of directors shall be made only by amendment to the certificate. The
Coast Charter and By-laws provide that the number of directors shall be
determined by a resolution of the majority of the Coast Board. The Ahmanson
By-Laws provide that the number of directors shall be determined by a resolution
of the majority of the Ahmanson Board or a majority of the voting power of the
outstanding shares of voting stock.

        Advance Notice of Stockholder Nominations of Directors. Under the Coast
By-laws, nominations of persons for election to the Coast Board may be made at a
meeting of stockholders by any stockholder, provided that the Secretary of Coast
receives written notice not less than 30 days prior to the annual meeting.

        Under the Ahmanson By-Laws, nominations of persons for election to the
Ahmanson Board may be made at a meeting of stockholders by any stockholder,
provided that the Secretary of Ahmanson receives written notice not less than 60
days nor more than 120 days prior to the meeting. If less than 65 days' notice
or prior public disclosure of the date of the meeting is given or made by
Ahmanson to stockholders, the notice of a nomination must be received not later
than the close of business on the tenth day following the day on which such
notice of the date of the annual meeting was mailed or public disclosure was
made. Stockholder notices must state, among other things, a brief description of
the business desired to be brought before the annual meeting and the reasons for
conducting such business at the annual meeting, the name and record address of
the stockholder proposing the business, the class and number of shares of
Ahmanson stock beneficially owned by the stockholder, any material interest in
such business and any other information relating to the stockholder or the
proposal required to be disclosed in solicitations for proxies for the election
of directors pursuant to Regulation 14A under the Exchange Act.




                                      -71-
<PAGE>   79

        Classification of Board of Directors. Delaware law permits (but does not
require) a certificate of incorporation to provide that a board of directors be
divided into classes, with each class having a term of office longer than one
year but not longer than three years. The Coast Charter provides that the Coast
Board shall have three classes. The directors of each class shall serve for a
term ending at the third annual meeting following the annual meeting at which
they were elected. The Ahmanson Charter does not provide for a classified board.
Accordingly, all members of the Ahmanson Board are elected at each annual
meeting.

INDEMNIFICATION

        The Coast Charter generally provides for the indemnification of persons
serving as a director or officer of Coast or at the request of Coast as a
director or officer of another corporation, partnership, joint venture, trust or
other enterprise against all costs and expenses reasonably incurred by such
person or on such person's behalf in connection with such action, suit or
proceeding and any appeal therefrom, if such person acted in good faith and in a
manner such person reasonably believed to be in the best interests of the
corporation and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The Ahmanson Charter and
By-Laws generally provide for the indemnification of persons serving as a
director, officer, employee or agent of Ahmanson or at the request of Ahmanson
as a director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, to the fullest extent
authorized by the DGCL. The Ahmanson By-Laws provide that such right to
indemnification may only be extended to employees and agents in a specific case
by action of the Ahmanson Board.

CERTAIN VOTING RIGHTS

        With Respect to Proposed Mergers. Under Delaware law, certain mergers
and consolidations or the sale of all or substantially all of the assets of a
corporation requires the approval of the holders of a majority (unless the
certificate of incorporation requires a higher percentage) of the outstanding
shares of such corporation entitled to vote thereon. Neither the Coast Charter
nor the Ahmanson Charter requires a higher percentage generally, except under
certain situations involving substantial stockholders discussed below.

        With Respect to Transactions with Substantial Stockholders. The Coast
Charter provides that certain transactions between Coast and a substantial
stockholder (generally a person holding more than 10% of the outstanding voting
stock of Coast) require the approval of the holders of two-thirds of all
outstanding shares of capital stock of Coast entitled to vote generally in the
election of directors, including (i) the merger or consolidation of Coast or any
subsidiary of Coast; (ii) the sale, lease or other disposition of any assets of
Coast having an aggregate fair market value of $20 million or more; (iii) the
issuance or transfer by Coast or any subsidiary of Coast of securities of Coast
or a subsidiary of Coast having an aggregate fair market value of $20 million or
more; (iv) the adoption of a plan or proposal for the liquidation of dissolution
of any subsidiary of Coast; (v) the reclassification of securities,
recapitalization, consolidation or any other transaction that has the direct or
indirect effect of increasing the voting power of any such substantial
stockholder in any class or series of capital stock of Coast or any subsidiary
of Coast; or (vi) any agreement, contract or other arrangement providing
directly or indirectly for any of the foregoing; except, in each case, for any
transaction approved by a vote of a majority of directors unaffiliated with the
Substantial Stockholder and its affiliates, or any transaction to be consummated
within three years after the Substantial Stockholder becomes a Substantial
Stockholder and if certain conditions are met.

        The Ahmanson Charter provides that certain transactions between Ahmanson
and a substantial stockholder (generally a person or group holding capital stock
representing 10% or more of the outstanding voting power of Ahmanson) require
the approval of the holders of 80% of the capital stock of Ahmanson entitled to
vote for the election of directors, including (i) the repurchase by Ahmanson of
capital stock representing 10% or more of the total voting power of Ahmanson
from such a substantial stockholder under certain circumstances, (ii) certain
mergers, consolidations, combinations or reorganizations of Ahmanson or the sale
of all or a substantial part of the assets of Ahmanson or its subsidiaries where
such a substantial stockholder or its affiliates are parties to the transaction
and (iii) certain other exchanges of securities, cash or other properties or
assets of Ahmanson involving such a substantial stockholder or its affiliates,
except, in the case of (ii) or (iii), for any transaction which has been
approved by the Ahmanson Board,

including by the vote of at least two-thirds of the directors unaffiliated with
the substantial stockholder and its affiliates.

        Cumulative Voting. Under Delaware law, stockholders of a corporation are
not entitled to cumulate their votes in the election of directors unless the
corporation's certificate of incorporation so provides. Neither the Coast
Charter nor the Ahmanson Charter provides for cumulative voting.

REMOVAL OF DIRECTORS; FILLING VACANCIES ON THE BOARD OF DIRECTORS

        Under Delaware law, any or all directors of a corporation which does not
have cumulative voting or a classified board may be removed, with or without
cause, by the holders of a majority of the shares entitled to vote at an
election of directors, unless such corporation's certificate of incorporation
provides otherwise. Coast has a classified board and the Coast Charter provides
that directors may be removed only for cause, which is defined in the Coast
Charter to mean conviction for a felony or a non-appealable adjudication against
the director for gross negligence or misconduct. The Ahmanson Charter does not
limit the right of stockholders to remove directors with or without cause.

        Under Delaware law, unless otherwise provided in the corporation's
certificate of incorporation or by-laws, vacancies and newly-created
directorships resulting from any increase in the authorized number of directors
may be filled by a majority of the directors in office. The Coast Charter
provides that any vacancy, whether arising through death, resignation,
retirement, disqualification, removal or other cause, may be filled only by a
majority vote of the remaining directors or by the sole remaining director if
only one such director remains or by the stockholders if the directors or
director fail to so act. Neither the Ahmanson Charter nor the Ahmanson By-Laws
provides for vacancies or newly-created directorships to be filled by
stockholder vote.

STOCKHOLDER ACTION BY WRITTEN CONSENT

        Under Delaware law, unless otherwise provided in the certificate of
incorporation, any action which may be taken at any annual or special meeting
may be taken without a meeting and without prior notice if a consent in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
shares having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted. The Coast Charter and By-laws provide that
any action by written stockholder consent must be signed by all the stockholders
of Coast entitled to vote. The Ahmanson Charter prohibits any action by written
stockholder consent.

AMENDMENT OF BY-LAWS

        Under Delaware law, the power to adopt, amend or repeal by-laws is
vested in the stockholders unless the certificate of incorporation confers the
power to adopt, amend or repeal by-laws upon the directors as well. Both the
Coast Charter and the Ahmanson Charter grant such power to their respective
boards of directors. The Coast By-laws provide that the Coast By-laws may not be
amended or repealed by the stockholders without the approval of the holders of
two-thirds of the voting stock of Coast.

RIGHTS PLANS

        Ahmanson Rights Plan. On November 7, 1997, the Ahmanson Board declared a
dividend distribution of one preferred stock purchase right (a "Right"), to
holders of Ahmanson Common Stock outstanding on November 17, 1997.



                                      -73-
<PAGE>   81
        In the event that any person or affiliated group becomes the beneficial
owner of 15% or more of the outstanding shares of Ahmanson Common Stock, each
holder of a Right (other than Rights beneficially owned by the 15% beneficial
owner) will thereafter have the right to purchase from Ahmanson that number of
shares of Ahmanson Common Stock having a market value equal to two times the
exercise price of the Right. If Ahmanson thereafter is acquired in a merger or
other business combination transaction or 50% or more of its consolidated assets
or earning power are sold, proper provision will be made so that each holder of
a Right other than Rights beneficially owned by the acquiring person, will
thereafter have the right to receive, upon the exercise thereof at the then
current exercise price of the Right (currently, $60), that number of shares of
common stock of the acquiring company which at the time of such transaction will
have a market value of two times the exercise price of the Right.

        Coast Rights Plan. On August 23, 1989, the Coast Board declared a
dividend distribution of one Coast Right for each share of Coast Common Stock
outstanding on September 6, 1989.

        In the event that any person becomes the beneficial owner of 15% or more
of the outstanding shares of Coast Common Stock, proper provision is required to
be made so that each holder of a Coast Right, other than Coast Rights
beneficially owned by the acquiring person, will thereafter have the right to
receive upon exercise that number of shares of Coast Common Stock having a
market value equal to two times the exercise price of the Coast Right. In the
event that, at any time following such acquisition of 15% or more of the
outstanding shares, Coast is acquired in a merger or other business combination
transaction or 50% or more of its consolidated assets or earning power are sold
(with certain exceptions), proper provision will be made so that each holder of
a Coast Right will thereafter have the right to receive, upon the exercise
thereof at the then current exercise price of the Coast Right, that number of
shares of common stock of the acquiring company which at the time of such
transaction will have a market value equal to two times the exercise price of
the Coast Right. At the Effective Time, the Coast Rights, which currently trade
with, and are represented by the certificates for, Coast Common Stock, will be
canceled and no additional consideration will be payable with respect thereto.

        3.03 Fractional Shares. Notwithstanding any other provision hereof, no
fractional shares of Ahmanson Common Stock and no certificates or scrip
therefor, or other evidence of ownership thereof, will be issued in the Merger;
instead, Ahmanson shall pay to each holder of Coast Common Stock who would
otherwise be entitled to a fractional share of Ahmanson Common Stock (after

or, if not reported therein, in another authoritative source), for the five NYSE
trading days immediately preceding the Effective Date.

    Common Stock ("Old Certificates") to be exchanged in accordance with this
    Article III, certificates representing the shares of Ahmanson Common Stock

    entitled pursuant to this Agreement, together with an estimated amount of
    cash to be paid pursuant to this Article III in exchange for outstanding
    shares of Coast Common Stock.

        (b) As promptly as practicable after the Effective Date, Ahmanson shall
    send or cause to be sent to each former holder of record of shares of Coast
    Common Stock immediately prior to the Effective Time transmittal materials
    for use in exchanging such stockholder's Old Certificates for the
    consideration set forth in this Article III. Ahmanson shall cause the New
    Certificates and/or any check in respect of any fractional share interests
    or dividends or distributions which such person shall be entitled to receive
    to be delivered to such stockholder upon delivery to the Exchange Agent of
    Old Certificates representing such shares of Coast Common Stock (or
    indemnity reasonably satisfactory to Ahmanson and the Exchange Agent, if any
    of such certificates are lost, stolen or destroyed) owned by such
    stockholder. No interest will be paid on any such cash to be paid in lieu of
    fractional share interests or in respect of dividends or distributions which
    any such person shall be entitled to receive pursuant to this Article III
    upon such delivery.

        (c) Notwithstanding the foregoing, neither the Exchange Agent nor any
    party hereto shall be liable to any former holder of Coast Common Stock for
    any amount properly delivered to a public official pursuant to applicable
    abandoned property, escheat or similar laws.

        (d) At the election of Ahmanson, no dividends or other distributions
    with respect to Ahmanson Common Stock with a record date occurring after the
    Effective Time shall be paid to the holder of any unsurrendered Old
    Certificate representing shares of Coast Common Stock converted in the
    Merger into the right to receive shares of such Ahmanson Common Stock. Upon
    surrender of Old Certificates (or indemnity reasonably satisfactory to
    Ahmanson and the Exchange Agent, if any of such certificates are lost,
    stolen or destroyed) in accordance with this Section 3.04, the record holder
    thereof shall be entitled to receive any such dividends or other
    distributions, without any interest thereon, which theretofore had become
    payable with respect to shares of Ahmanson Common Stock such holder had the
    right to receive upon surrender of Old Certificates (or delivery of such
    indemnity).

        3.05 Anti-Dilution Provisions. In the event Ahmanson changes (or
establishes a record date for changing) the number or kind of shares of Ahmanson
Common Stock issued and outstanding prior to the Effective Date as a result of a
stock split, stock dividend, recapitalization, reclassification, reorganization
or similar transaction with respect to the outstanding Ahmanson Common Stock and
the record date therefor shall be prior to the Effective Date, the Exchange
Ratio shall be proportionately adjusted in such manner as Coast and Ahmanson
shall agree, which adjustment may


                                       A-7

<PAGE>   96



include, as appropriate, the issuance of securities, property or cash on the
same basis as that on which any of the foregoing shall have been issued,
distributed or paid to the holders of Ahmanson Common Stock generally.

        3.06 Options, Performance Shares and Stock Appreciation Rights. (a) At
the Effective Time, each outstanding option to purchase shares of Coast Common
Stock under the Coast Stock Plans (each, a "Coast Stock Option"), whether vested
or unvested, shall be converted into an option (a "Replacement Option") to
acquire, on the same terms and conditions as were applicable under such Coast
Stock Option, (a) the number of shares of Ahmanson Common Stock equal to (i) the
number of shares of Coast Common Stock subject to the Coast Stock Option,
multiplied by (ii) the Exchange Ratio (such product rounded down to the nearest
whole number), at an exercise price per share (rounded up to the nearest whole
cent) equal to (A) the aggregate exercise price for the shares of Coast Common
Stock which were purchasable pursuant to such Coast Stock Option divided by (B)
the number of full shares of Ahmanson Common Stock subject to such Replacement
Option in accordance with the foregoing and (b) one CPR Certificate for each
share of Coast Common Stock that would have been issuable upon exercise in full
of such Coast Stock Option. At or prior to the Effective Time, Coast shall take
all necessary action, if any, including obtaining any necessary consents from
optionees, with respect to the Coast Stock Plans to permit the replacement of
the outstanding Coast Stock Options by Replacement Options pursuant to this
Section and to permit Ahmanson to assume the Coast Stock Plans. At the Effective
Time, Ahmanson shall assume the Coast Stock Plans; provided, that such
assumption shall be only in respect of the Replacement Options and that Ahmanson
shall have no obligation with respect to any awards under the Coast Stock Plans
other than the Replacement Options and shall have no obligation to make any
additional grants or awards under such assumed Coast Stock Plans.

        (b) Immediately prior to the Effective Time, each outstanding
    performance share award under the Coast Performance Share Award Plan shall
    be canceled and only entitle the holder thereof to receive for each share of
    Coast Common Stock with respect to such award (i) one CPR Certificate and
    (ii) an amount in cash equal to the difference between (A) the result of
    multiplying the Exchange Ratio by the average of the last sale prices of one
    share of Ahmanson Stock, as reported by the NYSE Composite Transactions
    Reporting System (as reported in The Wall Street Journal or, if not reported
    therein, in another authoritative source) for the five NYSE trading days
    immediately prior to the Effective Date and (B) the base price under such
    award. Prior to the Effective Date, Coast shall take all necessary action
    with respect to such cancellation, including obtaining any necessary
    consents from the holders of such awards.

        (c) Immediately prior to the Effective Time, each outstanding stock
    appreciation right under the Coast Stock Plans shall be canceled and only
    entitle the holder thereof to receive for each share of Coast Stock with
    respect to such stock appreciation right (i) one CPR Certificate and (ii) an
    amount in cash equal to the difference between (A) the result of multiplying
    the Exchange Ratio by the average of the last sale prices of one share of
    Ahmanson Stock, as reported by the NYSE Composite Transactions Reporting
    System (as reported in The Wall Street Journal or, if not reported therein,
    in another authoritative source) for the five NYSE trading days immediately
    prior to the Effective Date and (B) the grant price of such stock
    appreciation right. Prior to the Effective Date, Coast shall take all
    necessary action with respect to such cancellation, including obtaining any
    necessary consents from the holders of such stock appreciation rights.

        (d) If the necessary consents referred to in paragraphs (b) and (c)
    above are not obtained, the holders who do not consent shall only be
    entitled to (i) with respect to each outstanding performance share award
    under the Coast Performance Share Award Plan an amount in cash equal to the
    result of multiplying (A) the difference between the average of the last
    sale prices of one share of Coast Stock, as reported by the NYSE Composite
    Transactions Reporting System (as reported in The Wall Street Journal or, if
    not reported therein, in another authoritative source) for the five NYSE
    trading days immediately prior to the Effective Date and the base price
    under such award by (B) the total number of shares of Coast Stock with
    respect to such award and (ii) with respect to each outstanding stock
    appreciation right under the Coast Stock Plans, an amount in cash equal to
    the result of multiplying (A) the difference between the average of the last
    sale prices of one share of Coast Stock, as reported by the NYSE Composite
    Transactions Reporting System (as reported in The Wall Street Journal or, if
    not reported therein, in another authoritative source) for the five NYSE
    trading days immediately prior to the Effective Date and the grant


                                             A-8

<PAGE>   97



    price of such stock appreciation right by (B) the total number of shares of
    Coast Stock with respect to such stock appreciation right. All CPR
    Certificates with respect to the performance share awards and stock
    appreciation rights referred to in this Section shall be issued to Ahmanson.
    In the event that between the date hereof and the Effective Date any
    performance share awards or stock appreciation rights are exercised,
    Ahmanson will be entitled to retain any CPR Certificates that would
    otherwise have been issuable with respect to such performance share awards
    or stock appreciation rights upon such exercise at the Effective Date.

        3.07 Dissenters Rights. Any Dissenting Shareholder who shall be entitled
to be paid the "fair value" of his or her Dissenters' Shares, as provided in
Section 262 of the DGCL, shall not be entitled to the Merger Consideration in
respect thereof provided for under Section 3.01(a) unless and until such
Dissenting Shareholder shall have failed to perfect or shall have withdrawn or
lost such Dissenting Shareholder's right to dissent from the Merger under the
DGCL, and shall be entitled to receive only the payment provided for by Section
262 of the DGCL with respect to such Dissenters' Shares. If any Dissenting
Shareholder shall fail to perfect or shall have been withdrawn or lost such
right to dissent, the Dissenters' Shares held by such Dissenting Shareholder
shall thereupon be treated as though such Dissenters' Shares had been converted
into the right to receive the Merger Consideration pursuant to Section 3.01(a)
hereof.

delivered to Ahmanson a schedule (its "Disclosure Schedule") setting forth,
among other things, items the disclosure of which is necessary or appropriate
either in response to an express disclosure requirement contained in a provision
hereof or as an exception to one or more representations or warranties contained
in Section 5.03 or to one or more of its covenants contained in Article IV;
provided, that the mere inclusion of an item in a Disclosure Schedule as an
exception to a representation or warranty shall not be deemed an admission by
Coast that such item represents a material exception or fact, event or
circumstance or that such item is reasonably likely to result in a Material
Adverse Effect. Coast represents and warrants that its Disclosure Schedule is
true and correct in all material respects and does not omit any item or
information material to the applicable paragraph in Section 5.03 and required to
be disclosed therein.

        5.02 Standard. No representation or warranty of Coast or Ahmanson
contained in Section 5.03 or 5.04, shall be deemed untrue or incorrect, and no
party hereto shall be deemed to have breached a representation or warranty, as a

fact, circumstance or event, individually or taken together with all other
facts, events or circumstances inconsistent with any representation or warranty
contained in Section 5.03 or 5.04 has had or is reasonably likely to have a
Material Adverse Effect on the party making such representation or warranty.

        5.03 Representations and Warranties of Coast. Subject to Sections 5.01
and 5.02 and except as Previously Disclosed in the applicable paragraph of its

Ahmanson:

    Disclosure Schedule a list of all of its Subsidiaries together with the
    jurisdiction of organization of each such Subsidiary, (B) except as
    Previously Disclosed, it owns, directly or indirectly, all the issued and
    outstanding equity securities of each of its Subsidiaries, (C) no equity
    securities of any of its Subsidiaries are or may become required to be
    issued (other than to it or its wholly-owned Subsidiaries) by reason of any
    Right or otherwise, (D) there are no contracts, commitments, understandings

    nonassessable and are owned by Coast or its Subsidiaries free and clear of
    any Liens.

            (ii) Coast does not own beneficially, directly or indirectly, any
    equity securities or similar interests of any Person (other than in a
    fiduciary capacity or in connection with the foreclosure of security
    interests or as a result of similar enforcement remedies in connection with
    loans made in the ordinary course of business), or any interest in a
    partnership or joint venture of any kind, other than in its Subsidiaries.

            (iii) Each of Coast's Subsidiaries has been duly organized and is
    validly existing in good standing under the laws of the jurisdiction of its
    organization, and is duly qualified to do business and in good standing in
    the jurisdictions where its ownership or leasing of property or the conduct
    of its business requires it to be so qualified.

        (d) Corporate Power. Coast and each of its Subsidiaries has the
    corporate power and authority to carry on its business as it is now being
    conducted and to own all its properties and assets; and Coast has the
    corporate power and authority to execute, deliver and perform its
    obligations under this Agreement and to consummate the transactions
    contemplated hereby.

        (e) Corporate Authority. Subject in the case of this Agreement to
    receipt of the requisite approval of the agreement of merger set forth in
    this Agreement by the holders of a majority of the outstanding shares of
    Coast Common Stock entitled to vote thereon (which is the only stockholder
    vote required thereon), this Agreement and the transactions contemplated
    hereby have been authorized by all necessary corporate action of Coast and
    the Coast Board on or prior to the date hereof. This Agreement is a valid
    and legally binding obligation of Coast, enforceable


                                      A-12

<PAGE>   101



    in accordance with its terms (except as enforceability may be limited by
    applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
    transfer and similar laws of general applicability relating to or affecting
    creditors' rights or by general equity principles). The Coast Board has
    received the written opinion of Goldman, Sachs & Co. to the effect that as
    of the date hereof the consideration to be received by the holders of Coast
    Common Stock in the Merger is fair to the holders of Coast Common Stock from
    a financial point of view.

        (f) Regulatory Approvals; No Defaults. (i) No consents or approvals of,
    or filings or registrations with, any Governmental Authority or with any
    third party are required to be made or obtained by Coast or any of its

    stockholders of Coast, and (C) the filing of a certificate of merger with
    the Delaware Secretary pursuant to the DGCL. As of the date hereof, Coast is
    not aware of any reason why the approvals set forth in Section 7.01(b) will
    not be received without the imposition of a condition, restriction or
    requirement of the type described in Section 7.01(b).

            (ii) Subject to receipt of the regulatory approvals referred to in
    the preceding paragraph, and expiration of related waiting periods, and
    required filings under federal and state securities laws, the execution,
    delivery and performance of this Agreement and the consummation of the
    transactions contemplated hereby do not and will not (A) constitute a breach
    or violation of, or a default under, or give rise to any Lien, any
    acceleration of remedies or any right of termination under, any law, rule or
    regulation or any judgment, decree, order, governmental permit or license,
    or agreement, indenture or instrument of Coast or of any of its Subsidiaries
    or to which Coast or any of its Subsidiaries or properties is subject or
    bound, (B) constitute a breach or violation of, or a default under, the
    Coast Certificate or the Coast By-Laws, or (C) require any consent or
    approval under any such law, rule, regulation, judgment, decree, order,

    material respects as to form with the applicable requirements under the
    Securities Act, the Exchange Act or the securities regulations of the OTS,
    as the case may be, and (B) did not and will not contain any 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, in the light of
    the circumstances under which they were made, not misleading; and each of
    the consolidated balance sheets contained in or incorporated by reference
    into any such Regulatory Document (including the related notes and schedules
    thereto) fairly presents, or will fairly present, the consolidated financial
    position of Coast and its Subsidiaries as of its date, and each of the
    consolidated statements of income and changes in stockholders' equity and
    cash flows or equivalent statements in such Regulatory Documents (including
    any related notes and schedules thereto) fairly presents, or will fairly
    present, the consolidated results of operations, changes in stockholders'
    equity and changes in cash flows, as the case may be, of Coast and its
    Subsidiaries for the periods to which they relate, in each case in
    accordance with generally accepted accounting principles consistently
    applied during the periods involved, except in each case as may be noted
    therein, subject to normal year-end audit adjustments and the lack of
    complete footnote disclosure in the case of unaudited statements.

            (ii) Except as Previously Disclosed in its Disclosure Schedule,
    since December 31, 1996, Coast and its Subsidiaries have not incurred any
    liability other than in the ordinary course of business consistent with past
    practice (other than liabilities (A) with respect to expenses related to
    this Agreement and the transactions contemplated hereby and (B) with respect
    to other possible merger transactions all of which have been expensed or
    reserved for).

<PAGE>   102



           (iii) Since December 31, 1996, (A) Coast and its Subsidiaries have
    conducted their respective businesses in the ordinary and usual course
    consistent with past practice (excluding the incurrence of expenses related
    to this Agreement and the transactions contemplated hereby and other
    possible merger transactions) and (B) no event has occurred or circumstance
    arisen that, individually or taken together with all other facts,
    circumstances and events (described in any paragraph of Section 5.03 or
    otherwise), is reasonably likely to have a Material Adverse Effect with
    respect to Coast.

        (h) Litigation. No litigation, claim or other proceeding before any
    court or governmental agency is pending against Coast or any of its
    Subsidiaries and, to Coast's knowledge, no such litigation, claim or other
    proceeding has been threatened.

        (i) Regulatory Matters. (i) Neither Coast nor any of its Subsidiaries or
    properties is a party to or is subject to any order, decree, agreement,
    memorandum of understanding or similar arrangement with, or a commitment
    letter or similar submission to, or extraordinary supervisory letter from,
    any federal or state governmental agency or authority charged with the
    supervision or regulation of financial institutions or issuers of securities
    or engaged in the insurance of deposits (including, without limitation, the
    OTS and the FDIC) or the supervision or regulation of it or any of its
    Subsidiaries (collectively, the "Regulatory Authorities").

            (ii) Neither Coast nor any of its Subsidiaries has been advised by
    any Regulatory Authority that such Regulatory Authority is contemplating
    issuing or requesting (or is considering the appropriateness of issuing or
    requesting) any such order, decree, agreement, memorandum of understanding,
    commitment letter, supervisory letter or similar submission.

        (j) Compliance with Laws.  Coast and each of its Subsidiaries:

            (i) is in compliance with all applicable federal, state, local and
    foreign statutes, laws, regulations, ordinances, rules, judgments, orders or
    decrees applicable thereto or to the employees conducting such businesses,
    including, without limitation, the Equal Credit Opportunity Act, the Fair
    Housing Act, the Community Reinvestment Act, the Home Mortgage Disclosure
    Act and all other applicable fair lending laws and other laws relating to
    discriminatory business practices;

            (ii) has all permits, licenses, authorizations, orders and approvals
    of, and has made all filings, applications and registrations with, all
    Governmental Authorities that are required in order to permit them to own or
    lease their properties and to conduct their businesses substantially as
    presently conducted; all such permits, licenses, certificates of authority,
    orders and approvals are in full force and effect; and, to Coast's
    knowledge, no suspension or cancellation of any of them is threatened; and

            (iii) has received, since December 31, 1996, no notification or
    communication from any Governmental Authority (A) asserting that Coast or
    any of its Subsidiaries is not in compliance with any of the statutes,
    regulations, or ordinances which such Governmental Authority enforces or (B)
    threatening to revoke any license, franchise, permit, or governmental
    authorization (nor, to Coast's knowledge, do any grounds for any of the
    foregoing exist).

        (k) Material Contracts; Defaults. Except for those agreements and other
    documents filed as exhibits to its Regulatory Documents, neither Coast nor
    any of its Subsidiaries is a party to, bound by or subject to any agreement,
    contract, arrangement, commitment or understanding (whether written or oral)
    (i) that is a "material contract" within the meaning of Item 601(b)(10) of
    the SEC's Regulation S-K or (ii) that materially restricts the conduct of
    business by it or any of its Subsidiaries. Neither Coast nor any of its
    Subsidiaries is in default in any material respect under any material
    contract, agreement, commitment, arrangement, lease, insurance policy or
    other instrument to which it is a party, by which its respective assets,
    business, or operations may be bound or affected, or under which it or its
    respective assets, business, or operations receives benefits, or under any
    other contract if such default could


                                      A-14

<PAGE>   103



    reasonably be expected to have a Material Adverse Effect on Coast, and in
    either case there has not occurred any event that, with the lapse of time or
    the giving of notice or both, would constitute such a default.

        (l) No Brokers. No action has been taken by Coast that would give rise
    to any valid claim against any party hereto for a brokerage commission,
    finder's fee or other like payment with respect to the transactions
    contemplated by this Agreement, excluding a Previously Disclosed fee to be
    paid to Goldman, Sachs & Co.

        (m) Employee Benefit Plans. (i) Section 5.03(m)(i) of Coast's Disclosure
    Schedule contains a complete and accurate list of all existing bonus,
    incentive, deferred compensation, pension, retirement, profit-sharing,
    thrift, savings, employee stock ownership, stock bonus, stock purchase,
    restricted stock, stock option, severance, welfare and fringe benefit plans,
    employment or severance agreements and all similar practices, policies and
    arrangements in which any employee or former employee (the "Employees"),
    consultant or former consultant (the "Consultants") or director or former
    director (the "Directors") of Coast or any of its Subsidiaries participates
    or to which any such Employees, Consultants or Directors are a party (the
    "Compensation and Benefit Plans"). Neither Coast nor any of its Subsidiaries
    has any commitment to create any additional Compensation and Benefit Plan or
    to modify or change any existing Compensation and Benefit Plan.

            (ii) Each Compensation and Benefit Plan has been operated and
    administered in all material respects in accordance with its terms and with
    applicable law, including, but not limited to, ERISA, the Code, the
    Securities Act, the Exchange Act, the Age Discrimination in Employment Act,
    or any regulations or rules promulgated thereunder, and all filings,
    disclosures and notices required by ERISA, the Code, the Securities Act, the
    Exchange Act, the Age Discrimination in Employment Act and any other
    applicable law have been timely made. Each Compensation and Benefit Plan
    which is an "employee pension benefit plan" within the meaning of Section
    3(2) of ERISA (a "Pension Plan") and which is intended to be qualified under
    Section 401(a) of the Code has received a favorable determination letter
    (including a determination that the related trust under such Compensation
    and Benefit Plan is exempt from tax under Section 501(a) of the Code) from
    the Internal Revenue Service ("IRS") for "TRA" (as defined in Rev. Proc.
    93-39), or will file for such determination letter prior to the expiration
    of the remedial amendment period for such Compensation and Benefit Plan, and
    Coast is not aware of any circumstances likely to result in revocation of
    any such favorable determination letter. There is no material pending or, to
    the knowledge of Coast, threatened legal action, suit or claim relating to
    the Compensation and Benefit Plans. Neither Coast nor any of its
    Subsidiaries has engaged in a transaction, or omitted to take any action,
    with respect to any Compensation and Benefit Plan that would reasonably be
    expected to subject Coast or any of its Subsidiaries to a tax or penalty
    imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming
    for purposes of Section 4975 of the Code that the taxable period of any such
    transaction expired as of the date hereof.

            (iii) No liability (other than for payment of premiums to the PBGC
    which have been made or will be made on a timely basis) under Title IV of
    ERISA has been or is expected to be incurred by Coast or any of its
    Subsidiaries with respect to any ongoing, frozen or terminated
    "single-employer plan", within the meaning of Section 4001(a)(15) of ERISA,
    currently or formerly maintained by any of them, or any single-employer plan
    of any entity (an "ERISA Affiliate") which is considered one employer with
    Coast under Section 4001(a)(14) of ERISA or Section 414(b) or (c) of the
    Code (an "ERISA Affiliate Plan"). None of Coast, any of its Subsidiaries or
    any ERISA Affiliate has contributed, or has been obligated to contribute, to
    a multiemployer plan under Subtitle E of Title IV of ERISA during the
    preceding five calendar years. No notice of a "reportable event", within the
    meaning of Section 4043 of ERISA for which the 30-day reporting requirement
    has not been waived, has been required to be filed for any Compensation and
    Benefit Plan or by any ERISA Affiliate Plan within the 12-month period
    ending on the date hereof, and no such notice will be required to be filed
    as a result of the transactions contemplated by this Agreement. The PBGC has
    not instituted proceedings to terminate any Pension Plan or ERISA Affiliate
    Plan and, to Coast's knowledge, no condition exists that presents a material
    risk that such proceedings will be instituted. To the knowledge of Coast,
    there is no pending investigation or enforcement action by the PBGC, the
    Department of Labor or IRS or any other governmental agency with respect to
    any Compensation and Benefit Plan. Under each Pension Plan and ERISA
    Affiliate Plan, as of the date of the most recent actuarial valuation
    performed prior to the date of this Agreement, the actuarially determined
    present value of all "benefit liabilities", within the meaning of


                                      A-15

<PAGE>   104



    Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial
    assumptions contained in such actuarial valuation of such Pension Plan or
    ERISA Affiliate Plan), did not exceed the then current value of the assets
    of such Pension Plan or ERISA Affiliate Plan and since such date there has
    been neither an adverse change in the financial condition of such Pension
    Plan or ERISA Affiliate Plan nor any amendment or other change to such
    Pension Plan or ERISA Affiliate Plan that would increase the amount of
    benefits thereunder which in either case reasonably could be expected to
    change such result.

            (iv) All contributions required to be made under the terms of any
    Compensation and Benefit Plan or ERISA Affiliate Plan or any employee
    benefit arrangements under any collective bargaining agreement to which
    Coast or any of its Subsidiaries is a party have been timely made or have
    been reflected on Coast's financial statements to the extent required by
    generally accepted accounting principles. Neither any Pension Plan nor any
    ERISA Affiliate Plan has an "accumulated funding deficiency" (whether or not
    waived) within the meaning of Section 412 of the Code or Section 302 of
    ERISA and all required payments to the PBGC with respect to each Pension
    Plan or ERISA Affiliate Plan have been made on or before their due dates.
    None of Coast, any of its Subsidiaries or any ERISA Affiliate (x) has
    provided, or would reasonably be expected to be required to provide,
    security to any Pension Plan or to any ERISA Affiliate Plan pursuant to
    Section 401(a)(29) of the Code, and (y) has taken any action, or omitted to
    take any action, that has resulted, or would reasonably be expected to
    result, in the imposition of a lien under Section 412(n) of the Code or
    pursuant to ERISA.

            (v) Neither Coast nor any of its Subsidiaries has any obligations to
    provide retiree health and life insurance or other retiree death benefits
    under any Compensation and Benefit Plan, other than benefits mandated by
    Section 4980B of the Code, and each such Compensation and Benefit Plan may
    be amended or terminated without incurring liability thereunder. There has
    been no communication to Employees by Coast or any of its Subsidiaries that
    would reasonably be expected to promise or guarantee such Employees retiree
    health or life insurance or other retiree death benefits on a permanent
    basis.

            (vi) Coast and its Subsidiaries do not maintain any Compensation and
    Benefit Plans covering foreign Employees.

            (vii) With respect to each Compensation and Benefit Plan, if
    applicable, Coast has provided or made available to Ahmanson, true and
    complete copies of its existing (A) Compensation and Benefit Plan documents
    and amendments thereto and (B) trust instruments and insurance contracts.

            (viii)The consummation of the transactions contemplated by this
    Agreement would not, directly or indirectly (including, without limitation,
    as a result of any termination of employment prior to or following the
    Effective Time) reasonably be expected to (A) entitle any Employee,
    Consultant or Director to any payment (including severance pay or similar
    compensation) or any increase in compensation, (B) result in the vesting or
    acceleration of any benefits under any Compensation and Benefit Plan or (C)
    result in any material increase in benefits payable under any Compensation
    and Benefit Plan.

            (ix) Neither Coast nor any of its Subsidiaries maintains any
    compensation plans, programs or arrangements the payments under which would
    not reasonably be expected to be deductible as a result of the limitations
    under Section 162(m) of the Code and the regulations issued thereunder.

            (x) As a result, directly or indirectly, of the transactions
    contemplated by this Agreement (including, without limitation, as a result
    of any termination of employment prior to or following the Effective Time),
    none of Ahmanson, Coast or the Surviving Corporation, or any of their
    respective Subsidiaries will be obligated to make a payment that would be
    characterized as an "excess parachute payment" to an employee or consultant
    of Coast who is a "disqualified individual" (as such terms are defined in
    Section 280G of the Code), without regard to whether such payment is
    reasonable compensation for personal services performed or to be performed
    in the future.

        (n) Labor Matters. Neither Coast nor any of its Subsidiaries is a party
    to or is bound by any collective bargaining agreement, contract or other
    agreement or understanding with a labor union or labor organization, nor is
    Coast or any of its Subsidiaries the subject of a proceeding asserting that
    it or any such Subsidiary has committed an unfair labor practice (within the
    meaning of the National Labor Relations Act) or seeking to compel Coast or
    any such Subsidiary to bargain with any labor organization as to wages or
    conditions of employment, nor is there any strike or other labor dispute
    involving it or any of its Subsidiaries pending or, to Coast's knowledge,
    threatened, nor is Coast aware of any activity involving its or any of its
    Subsidiaries' employees seeking to certify a collective bargaining unit or
    engaging in other organizational activity.

        (o) Takeover Laws; Dissenters Rights. Coast has taken all action
    required to be taken by it in order to exempt this Agreement, and the
    transactions contemplated hereby from, and this Agreement and the
    transactions contemplated hereby are exempt from, the requirements of any
    "moratorium", "control share", "fair price", "affiliate transaction",
    "business combination" or other antitakeover laws and regulations of any
    state (collectively, "Takeover Laws"), including, without limitation, the
    State of Delaware, and including, without limitation, Section 203 of the
    DGCL.

        (p) Environmental Matters. To the best knowledge of Coast, neither the
    conduct nor operation of Coast or its Subsidiaries nor any condition of any
    property presently or previously owned, leased or operated by any of them
    (including, without limitation, in a fiduciary or agency capacity), or on
    which any of them holds a Lien, violates or violated Environmental Laws and
    no condition has existed or event has occurred with respect to any of them
    or any such property that, with notice or the passage of time, or both, is
    reasonably likely to result in liability under Environmental Laws. Neither
    Coast nor any of its Subsidiaries has received any notice from any person or
    entity that Coast or its Subsidiaries or the operation or condition of any
    property ever owned, leased, operated, or held as collateral or in a
    fiduciary capacity by any of them are or were in violation of or otherwise
    are alleged to have liability under any Environmental Law, including, but
    not limited to, responsibility (or potential responsibility) for the cleanup
    or other remediation of any pollutants, contaminants, or hazardous or toxic
    wastes, substances or materials at, on, beneath, or originating from any
    such property.

        (q) Tax Matters. (i)(A) All federal, state, local and foreign Tax
    Returns (including information returns) required to be filed by or on behalf
    of Coast or its Subsidiaries have been prepared in good faith and duly and
    timely filed, and all such filed Tax Returns are complete and accurate in
    all material respects. (B) Coast and each of its Subsidiaries have paid in
    full all Taxes due (including interest and penalties) or have provided
    adequate reserves for any such Taxes in the financial statements of Coast in
    accordance with generally accepted accounting principles, whether or not
    shown as being due on any of the Tax Returns referred to in clause (i)(A).
    (C) Neither Coast nor any of its Subsidiaries has received any memorandum or
    opinion from legal counsel that was sought in order to satisfy the
    reasonable cause exception (set forth in Section 6664(c) of the Code)
    applicable to the penalties for certain underpayments of Taxes set forth in
    Sections 6662 through 6664 of the Code. (D) There is no pending or
    threatened audit, examination, assessment or proposed assessment of a
    deficiency, or refund litigation with respect to any Taxes of Coast or its
    Subsidiaries. (E) All Taxes, interest, additions and penalties due with
    respect to completed and settled examinations or concluded litigation
    relating to Taxes of Coast or its Subsidiaries have been paid in full or
    adequate provision has been made for any such Taxes (in accordance with
    generally accepted accounting principles) on the financial statements of
    Coast. (F) Neither Coast nor its Subsidiaries has executed an extension or
    waiver of any statute of limitations on the assessment or collection of any
    Tax due that is currently in effect. (G) No power of attorney has been
    granted by or with respect to Coast or any of its Subsidiaries with respect
    to any matter relating to Taxes. (H) Neither Coast nor any of its
    Subsidiaries has made or will make a material election as to Taxes during
    the period from January 1, 1997 through the Effective Time, other than
    elections made on tax returns filed for the year ended on December 31, 1996.

        (ii)(A) No liens or other security interests have been imposed on any
    assets of Coast or its Subsidiaries in connection with any failure (or
    alleged failure) to pay any Tax. (B) Coast and its Subsidiaries have timely
    withheld, and paid over to the relevant governmental authority or other
    appropriate payee, all Taxes required to have been withheld and paid in
    connection with amounts paid or owing to any employee, independent
    contractor, creditor,

                                      A-17

<PAGE>   106



    stockholder, or other person. (C) Neither Coast nor any of its Subsidiaries
    is a party to any tax allocation or sharing agreement under which it has
    obligations to a party other than Coast or its Subsidiaries, is or has been
    a member of an affiliated group filing consolidated or combined tax returns
    (other than a group the common parent of which is or was Coast) or otherwise
    has any liability for the Taxes of any person (other than Coast or its
    Subsidiaries). (D) Neither Coast nor any of its Subsidiaries has any
    deferred intercompany gain or loss arising as a result of a deferred
    intercompany transaction within the meaning of Treasury Regulation Section
    1.1502-13 (or similar provision under state, local or foreign law) or any
    excess loss accounts within the meaning of Treasury Regulation Section
    1.1502-19. (E) Coast is not and has not been a United States real property
    holding corporation (as defined in Section 897(c)(2) of the Code) during the
    applicable period specified in Section 897(c)(1)(ii) of the Code.

        (iii) As of the date hereof, neither Coast nor any of its Subsidiaries
    has any reason to believe that any conditions exist that might prevent or
    impede the Merger from qualifying as a reorganization within the meaning of
    Section 368 of the Code, or otherwise prevent the conditions in Section 7.02
    from being met.

        (r) Risk Management Instruments. All interest rate swaps, caps, floors,
    option agreements, futures and forward contracts and other similar risk
    management arrangements, whether entered into for Coast's own account, or
    for the account of one or more of Coast's Subsidiaries or their customers
    (all of which are listed on Coast's Disclosure Schedule), were entered into
    in accordance with all applicable laws, rules, regulations and regulatory
    policies and with counterparties believed to be financially responsible at
    the time; each of them constitutes the valid and legally binding obligation
    of Coast or one of its Subsidiaries, enforceable in accordance with its
    terms (except as enforceability may be limited by applicable bankruptcy,
    insolvency, reorganization, moratorium, fraudulent transfer and similar laws
    of general applicability relating to or affecting creditors' rights or by
    general equity principles), and are in full force and effect. Neither Coast
    nor its Subsidiaries, nor to Coast's knowledge, any other party thereto, is
    in breach of any of its obligations under any such agreement or arrangement.

        (s) Books and Records. The books and records of Coast and its
    Subsidiaries have been fully, properly and accurately maintained in all
    material respects, and there are no material inaccuracies or discrepancies
    of any kind contained or reflected therein, and they fairly present the
    financial position of Coast and its Subsidiaries.

        (t) Insurance. Coast's Disclosure Schedule sets forth all of the
    insurance policies, binders, or bonds maintained by Coast or its
    Subsidiaries ("Insurance Policies"). Coast and its Subsidiaries are insured
    with reputable insurers against such risks and in such amounts as the
    management of Coast reasonably has determined to be prudent in accordance
    with industry practices. All the Insurance Policies are in full force and
    effect; Coast and its Subsidiaries are not in material default thereunder;
    and all claims thereunder have been filed in due and timely fashion.

        (u) Disclosure. The representations and warranties contained in this
    Section 5.03 do not contain any untrue statement of a material fact or omit
    to state any material fact necessary in order to make the statements and
    information contained in this Section 5.03 not misleading.

        5.04 Representations and Warranties of Ahmanson. Subject to Section
5.02, Ahmanson hereby represents and warrants to Coast as follows:

        (a) Organization, Standing and Authority. Ahmanson is a corporation duly
    organized, validly existing and in good standing under the laws of the State
    of Delaware. Ahmanson is duly qualified to do business and is in good
    standing in the states of the United States and foreign jurisdictions where
    its ownership or leasing of property or assets or the conduct of its
    business requires it to be so qualified. Ahmanson has in effect all federal,
    state, local, and foreign governmental authorizations necessary for it to
    own or lease its properties and assets and to carry on its business as it is
    now conducted. Ahmanson is duly registered as a savings and loan holding
    company under HOLA.

    stock of Ahmanson consists solely of 220,000,000 shares of Ahmanson Common
    Stock, of which no more than 94,441,674 shares were outstanding as of the

    more than 780,000 shares of 8.40% Series C preferred stock and 575,000
    shares of 6% Cumulative Convertible Series D preferred stock were

    issued or outstanding with respect to Ahmanson Stock and Ahmanson does not
    have any commitment to authorize, issue or sell any Ahmanson Stock or
    Rights, except pursuant to this Agreement.

           (ii) The shares of Ahmanson Common Stock to be issued in exchange for
    shares of Coast Common Stock in the Merger, when issued in accordance with
    the terms of this Agreement, will be duly authorized, validly issued, fully
    paid and nonassessable and not subject to pre-emptive rights.

    duly organized and is validly existing in good standing under the laws of
    the jurisdiction of its organization, and is duly qualified to do business

    property or the conduct of its business requires it to be so qualified and
    it owns, directly or indirectly, all the issued and outstanding equity
    securities of each of its Significant Subsidiaries.

        (d) Corporate Power. Ahmanson and each of its Significant Subsidiaries
    has the corporate power and authority to carry on its business as it is now
    being conducted and to own all its properties and assets; and Ahmanson has
    the corporate power and authority to execute, deliver and perform its
    obligations under this Agreement and to consummate the transactions
    contemplated hereby.

        (e) Corporate Authority. (i) This Agreement and the transactions
    contemplated hereby have been authorized by all necessary corporate action
    of Ahmanson and the Ahmanson Board. This Agreement is a valid and legally
    binding agreement of Ahmanson enforceable in accordance with its terms
    (except as enforceability may be limited by applicable bankruptcy,
    insolvency, reorganization, moratorium, fraudulent transfer and similar laws
    of general applicability relating to or affecting creditors' rights or by
    general equity principles). No Ahmanson stockholder approval is required for
    this Agreement and the transactions contemplated hereby under the DGCL,
    Ahmanson's certificate of incorporation or Ahmanson's by-laws or the rules
    of the NYSE.

           (ii) The entering into of the Commitment has been authorized by all
    necessary corporate action of Ahmanson. The entering into of the Commitment
    will not (A) constitute a breach or violation of, or a default under, or
    give rise to any Lien, any acceleration of remedies or any right of
    termination under, any law, rule or regulation or any judgment, decree,
    order, governmental permit or license, or agreement, indenture or instrument
    of Ahmanson or of any of its Subsidiaries or to which Ahmanson or any of its
    Subsidiaries or properties is subject or bound, (B) constitute a breach or
    violation of, or a default under, the certificate of incorporation or
    by-laws of Ahmanson, or (C) require any consent or approval under any such
    law, rule, regulation, judgment, decree, order, governmental permit or
    license, agreement, indenture or instrument.

        (f) Regulatory Approvals; No Defaults. (i) No consents or approvals of,
    or filings or registrations with, any Governmental Authority or with any
    third party are required to be made or obtained by Ahmanson or any of its
    Subsidiaries in connection with the execution, delivery or performance by
    Ahmanson of this Agreement or to consummate the Merger except for (A) the
    filings and approvals of applications with and by the OTS; (B) approval of
    the listing on the NYSE of Ahmanson Common Stock to be issued in the Merger;
    (C) the filing and declaration of effectiveness of the Ahmanson Registration
    Statement; (D) the filing of a certificate of merger with the Delaware
    Secretary pursuant to the DGCL; and (E) such filings as are required to be
    made or approvals as are required to be obtained under the securities or
    "Blue Sky" laws of various states in connection with the issuance of
    Ahmanson Stock in the Merger. As of the date hereof, Ahmanson is not aware
    of any reason why the approvals set forth in

                                      A-19

<PAGE>   108



    Section 7.01(b) will not be received without the imposition of a condition,
    restriction or requirement of the type described in Section 7.01(b).

           (ii) Subject to receipt of the regulatory approvals referred to in
    the preceding paragraph and expiration of the related waiting periods, and
    required filings under federal and state securities laws, the execution,
    delivery and performance of this Agreement and the consummation of the
    transactions contemplated hereby do not and will not (A) constitute a breach
    or violation of, or a default under, or give rise to any Lien, any
    acceleration of remedies or any right of termination under, any law, rule or
    regulation or any judgment, decree, order, governmental permit or license,
    or agreement, indenture or instrument of Ahmanson or of any of its
    Subsidiaries or to which Ahmanson or any of its Subsidiaries or properties
    is subject or bound, (B) constitute a breach or violation of, or a default
    under, the certificate of incorporation or by-laws (or similar governing
    documents) of Ahmanson or any of its Subsidiaries, or (C) require any
    consent or approval under any such law, rule, regulation, judgment, decree,
    order, governmental permit or license, agreement, indenture or instrument.

        (g) Financial Reports and Regulatory Documents; Material Adverse Effect.
    (i) Ahmanson's Regulatory Documents, as of the date filed, (A) complied or
    will comply in all material respects as to form with the applicable
    requirements under the Securities Act or the Exchange Act, as the case may
    be, and (B) did not and will not contain any 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, in the light of the circumstances
    under which they were made, not misleading; and each of the balance sheets
    contained in or incorporated by reference into any such Regulatory Document
    (including the related notes and schedules thereto) fairly presents, or will
    fairly present, the financial position of Ahmanson and its Subsidiaries as
    of its date, and each of the statements of income and changes in
    stockholders' equity and cash flows or equivalent statements in such
    Regulatory Documents (including any related notes and schedules thereto)
    fairly presents, or will fairly present, the results of operations, changes
    in stockholders' equity and changes in cash flows, as the case may be, of
    Ahmanson and its Subsidiaries for the periods to which they relate, in each
    case in accordance with generally accepted accounting principles
    consistently applied during the periods involved, except in each case as may
    be noted therein, subject to normal year-end audit adjustments and the lack
    of complete footnote disclosure in the case of unaudited statements.

           (ii) Since December 31, 1996, no event has occurred or circumstance
    arisen that, individually or taken together with all other facts,
    circumstances and events (described in any paragraph of Section 5.04 or
    otherwise), is reasonably likely to have a Material Adverse Effect with
    respect to it.

        (h) Litigation; Regulatory Action. (i) Other than as set forth in its
    Regulatory Documents filed on or before the date hereof, no litigation,
    claim or other proceeding before any Governmental Authority is pending
    against Ahmanson or any of its Subsidiaries and, to the best of Ahmanson's
    knowledge, no such litigation, claim or other proceeding has been
    threatened.

           (ii) Neither Ahmanson nor any of its Subsidiaries or properties is a
    party to or is subject to any order, decree, agreement, memorandum of
    understanding or similar arrangement with, or a commitment letter or similar
    submission to, or extraordinary supervisory letter from a Regulatory
    Authority, nor has Ahmanson or any of its Subsidiaries been advised by a
    Regulatory Authority that such agency is contemplating issuing or requesting
    (or is considering the appropriateness of issuing or requesting) any such
    order, decree, agreement, memorandum of understanding, commitment letter,
    supervisory letter or similar submission.

        (i) Compliance with Laws.  Ahmanson and each of its Subsidiaries:

           (i) is in compliance with all applicable federal, state, local and
    foreign statutes, laws, regulations, ordinances, rules, judgments, orders or
    decrees applicable thereto or to the employees conducting such businesses,
    including, without limitation, the Equal Credit Opportunity Act, the Fair
    Housing Act, the Community Reinvestment Act, the Home Mortgage Disclosure
    Act and all other applicable fair lending laws and other laws relating to
    discriminatory business practices;


                                      A-20

<PAGE>   109

            (ii) has all permits, licenses, authorizations, orders and approvals
    of, and has made all filings, applications and registrations with, all
    Governmental Authorities that are required in order to permit them to
    conduct their businesses substantially as presently conducted; all such
    permits, licenses, certificates of authority, orders and approvals are in
    full force and effect and, to the best of its knowledge, no suspension or
    cancellation of any of them is threatened; and

            (iii) has received, since December 31, 1996, no notification or
    communication from any Governmental Authority (A) asserting that Ahmanson or
    any of its Subsidiaries is not in compliance with any of the statues,
    regulations, or ordinances which such Governmental Authority enforces or (B)
    threatening to revoke any license, franchise, permit, or governmental
    authorization (nor, to Ahmanson's knowledge, do any grounds for any of the
    foregoing exist).

        (j) No Brokers. No action has been taken by Ahmanson that would give
    rise to any valid claim against any party hereto for a brokerage commission,
    finder's fee or other like payment with respect to the transactions
    contemplated by this Agreement, excluding a fee to be paid to Merrill Lynch,
    Pierce, Fenner & Smith Incorporated.

        (k) Tax Matters. As of the date hereof, neither Ahmanson nor any of its
    Subsidiaries has any reason to believe that any conditions exist that might
    prevent or impede the Merger from qualifying as a reorganization within the
    meaning of Section 368 of the Code, or otherwise prevent the conditions in
    Section 7.03 from being met.

        (l) Disclosure. The representations and warranties contained in this
    Section 5.04 do not contain any untrue statement of a material fact or omit
    to state any material fact necessary in order to make the statements and
    information contained in this Section 5.04 not misleading.

                                   ARTICLE VI

                                    COVENANTS

        6.01 Reasonable Best Efforts. Subject to the terms and conditions of
this Agreement, each of Coast and Ahmanson agrees to use its reasonable best
efforts in good faith to take, or cause to be taken, all actions, and to do, or
cause to be done, all things necessary, proper or desirable, or advisable under
applicable laws, so as to permit consummation of the Merger as promptly as
practicable and otherwise to enable consummation of the transactions
contemplated hereby and shall cooperate fully with the other party hereto to
that end.

        6.02 Stockholder Approval. Coast agrees to take in accordance with
applicable law and its certificate of incorporation and by-laws all action
necessary to convene a meeting of its stockholders to consider and vote upon the
approval and adoption of this Agreement and the transactions contemplated hereby
(including the approval of the establishment of the CPR Trust, the engagement of
the Litigation Trustees (including the terms of their engagement) and the terms
of the Commitment and the rights of holders of Trust Certificates) and any other
matters required to be approved by Coast's stockholders for consummation of the
Merger (including any adjournment or postponement, the "Coast Meeting"), as
promptly as practicable after the Registration Statements are declared
effective. Subject to the proviso in the first sentence of Section 6.06, the
Coast Board shall recommend such approval, and Coast shall take all reasonable,
lawful action to solicit such approval by its stockholders.

        6.03 Registration Statements. (a) Ahmanson agrees to prepare a
registration statement on Form S-4 or other applicable form (the "Ahmanson
Registration Statement") to be filed by Ahmanson with the SEC in connection with
the issuance of Ahmanson Common Stock in the Merger (including the proxy
statement and prospectus and other proxy solicitation materials of Coast
constituting a part thereof (the "Proxy Statement") and all related documents).
Coast agrees to cooperate, and to cause its Subsidiaries to cooperate, with
Ahmanson, its counsel and its accountants, in the preparation of the Ahmanson
Registration Statement and the Proxy Statement; and Coast agrees to file the
Proxy Statement in preliminary form with the SEC as promptly as reasonably
practicable, and Ahmanson agrees to file the


                                      A-21

<PAGE>   110

Ahmanson Registration Statement with the SEC as soon as reasonably practicable
after any SEC comments with respect to the preliminary Proxy Statement are
resolved. Each of Coast and Ahmanson agrees to use all reasonable efforts to
cause the Ahmanson Registration Statement to be declared effective under the
Securities Act as promptly as reasonably practicable after filing thereof.
Ahmanson also agrees to use all reasonable efforts to obtain all necessary state
securities law or "Blue Sky" permits and approvals required to carry out the
transactions contemplated by this Agreement. Coast agrees to furnish to Ahmanson
all information concerning Coast, its Subsidiaries, officers, directors and
stockholders as may be reasonably requested in connection with the foregoing.
Coast agrees to prepare a registration statement on Form S-1 or other applicable
form (the "CPR Trust Registration Statement" and, together with the Ahmanson
Registration Statement, the "Registration Statements") to be filed by the CPR
Trust with the SEC in connection with the distribution of the CPR Certificates
(including the prospectus constituting a part thereof (the "CPR Prospectus") and
all related documents). Coast agrees to cause the CPR Trust Registration
Statement to be filed with the SEC as soon as reasonably practicable after the
date hereof. Coast agrees to use all reasonable efforts to cause the CPR Trust
Registration Statement to be declared effective under the Securities Act as
promptly as reasonably practicable after filing thereof and to cause the Trust
Agreement to be qualified under the Trust Indenture Act. Coast also agrees to
use all reasonable efforts to obtain all necessary state securities law or "Blue
Sky" permits and approvals required to carry out the distribution of the CPR
Certificates by Coast. Ahmanson agrees to furnish to Coast all information
concerning Ahmanson, its Subsidiaries, officers, directors and stockholders as
may be reasonably requested in connection with the foregoing.

        (b) Each of Coast and Ahmanson agrees, as to itself and its
    Subsidiaries, that none of the information supplied or to be supplied by it
    for inclusion or incorporation by reference in the Registration Statements
    will, at the time the Registration Statements and each amendment or
    supplement thereto, if any, becomes effective under the Securities Act,
    contain any untrue statement of a material fact or omit to state any
    material fact required to be stated therein or necessary to make the
    statements therein not misleading, the Proxy Statement and any amendment or
    supplement thereto will, at the date of mailing to stockholders and at the
    time of the Coast Meeting contain any untrue statement of a material fact or
    omit to state any material fact required to be stated therein or necessary
    to make the statements therein not misleading or any statement which, in the
    light of the circumstances under which such statement is made, will be false
    or misleading with respect to any material fact, or which will omit to state
    any material fact necessary in order to make the statements therein not
    false or misleading or necessary to correct any statement in any earlier
    statement in the Proxy Statement or any amendment or supplement thereto and
    the CPR Prospectus and any amendment or supplement thereto will, as of its
    date, contain any untrue statement of a material fact or omit to state any
    material fact required to be stated therein or necessary to make the
    statements therein not misleading or any statement which, in the light of
    the circumstances under which such statement is made, will be false or
    misleading with respect to any material fact, or which will omit to state
    any material fact necessary in order to make the statements therein not
    false or misleading or necessary to correct any statement in any earlier
    statement in the CPR Prospectus or any amendment or supplement thereto. Each
    of Coast and Ahmanson further agrees that if it shall become aware prior to
    the Effective Date of any information furnished by it that would cause any
    of the statements in the Proxy Statement, CPR Prospectus, CPR Trust
    Registration Statement or Ahmanson Registration Statement to be false or
    misleading with respect to any material fact, or to omit to state any
    material fact necessary to make the statements therein not false or
    misleading, to promptly inform the other party thereof and to take the
    necessary steps to correct the Proxy Statement, CPR Prospectus, CPR Trust
    Registration Statement or the Ahmanson Registration Statement.

        (c) Each of Ahmanson and Coast agrees to advise the other party,
    promptly after Ahmanson or Coast, as the case may be, receives notice
    thereof, of the time when the Ahmanson Registration Statement or the CPR
    Trust Registration Statement, as the case may be, has become effective or
    any supplement or amendment has been filed, of the issuance of any stop
    order or the suspension of the qualification of Ahmanson Common Stock or the
    CPR Certificates as the case may be, for offering or sale in any
    jurisdiction, of the initiation or threat of any proceeding for any such
    purpose, or of any request by the SEC for the amendment or supplement of the
    Ahmanson Registration Statement or the CPR Trust Registration Statement, as
    the case may be, or for additional information.

        6.04 Press Releases. Each of Coast and Ahmanson agrees that it will not,
without prior consultation with the other party, issue any press release or
written statement for general circulation relating to the transactions
contemplated hereby, except as otherwise required by applicable law or
regulation or NYSE rules. Each of Ahmanson and Coast will agree upon the joint
initial press release made with respect to the transactions contemplated hereby.

        6.05 Access; Information. (a) Each of Coast and Ahmanson agrees that
upon reasonable notice and subject to applicable laws relating to the exchange
of information, it shall afford the other party and the other party's officers,
employees, counsel, accountants and other authorized representatives, such
access during normal business hours throughout the period prior to the Effective
Time to the books, records (including, without limitation, tax returns and work
papers of independent auditors), properties, personnel and to such other
information as any party may reasonably request and, during such period, it
shall furnish promptly to such other party (i) a copy of each material report,
schedule and other document filed by it pursuant to the requirements of federal
or state securities or banking laws, and (ii) all other information concerning
the business, properties and personnel of it as the other may reasonably
request.

        (b) Each agrees that it will not, and will cause its representatives not
    to, use any information obtained pursuant to this Section 6.05 (as well as
    any other information obtained prior to the date hereof in connection with
    the entering into of this Agreement) for any purpose unrelated to the
    consummation of the transactions contemplated by this Agreement. Subject to
    the requirements of law, each party will keep confidential, and will cause
    its representatives to keep confidential, all information and documents
    obtained pursuant to this Section 6.05 (as well as any other information
    obtained prior to the date hereof in connection with the entering into of
    this Agreement) unless such information (i) was already known to such party,
    (ii) becomes available to such party from other sources not known by such
    party to be bound by a confidentiality obligation, (iii) is disclosed with
    the prior written approval of the party to which such information pertains
    or (iv) is or becomes readily ascertainable from published information or
    trade sources. In the event that this Agreement is terminated or the
    transactions contemplated by this Agreement shall otherwise fail to be
    consummated, each party shall promptly cause all copies of documents or
    extracts thereof containing information and data as to another party hereto
    to be returned to the party which furnished the same (or confirm in writing
    that all such copies have been destroyed). No investigation by either party
    of the business and affairs of the other shall affect or be deemed to modify
    or waive any representation, warranty, covenant or agreement in this
    Agreement, or the conditions to either party's obligation to consummate the
    transactions contemplated by this Agreement.

        (c) Except as contemplated by this Agreement and following termination
    of this Agreement, each party hereto agrees that for two years from
    September 18, 1997 it (and its affiliates) will not, alone or with others,
    in any manner, (a) acquire, agree to acquire, or make any offer or proposal
    (other than a confidential request to the Chairman of the Board for
    permission to make an offer or proposal) to acquire beneficial ownership of
    any securities or material properties of the other party (and its
    Subsidiaries), unless such acquisition or agreement or the making of such
    offer or proposal, shall have been expressly first approved by the other
    party's Board of Directors or (b) solicit proxies from stockholders of the
    other party.

        6.06 Acquisition Proposals. Coast agrees that it shall not, and shall
cause its Subsidiaries and its and its Subsidiaries' officers, directors,
agents, advisors and affiliates not to, solicit or encourage inquiries or
proposals with respect to, or engage in any negotiations concerning, or provide
any confidential information to, or have any discussions with, any person
relating to, any Acquisition Proposal or waive any provision of or amend the
terms of the Coast Rights Agreement in respect of an Acquisition Proposal;
provided, however, that nothing in this Agreement shall (x) require the Coast
Board to recommend stockholder approval of the Merger following an Acquisition
Proposal, (y) prevent Coast or the Coast Board from (i) engaging in any
discussions or negotiations with, or providing any information to, any Person in
response to an unsolicited bona fide written Acquisition Proposal by any such
Person or (ii) recommending such an unsolicited bona fide written Acquisition
Proposal to the holders of Coast Common Stock or (z) prevent Coast from waiving
any provision of or amending the terms of the Coast Rights Agreement in respect
of an Acquisition Proposal, if and only if, with respect to the actions
described in clause (x), (y) or (z), as applicable, (A) the Coast Board
concludes in good faith that the Acquisition Proposal, if consummated, would
result in a transaction more favorable to holders of Coast Common Stock than the
transaction contemplated by this Agreement; (B) the Coast Board determines


                                      A-23

<PAGE>   112



in good faith based upon the advice of outside counsel that such action is
legally necessary for it to act in a manner consistent with its fiduciary duties
under applicable law; and (C) prior to providing any information or data to any
person or entering into discussions or negotiations with any Person, the Coast
Board notifies Ahmanson immediately of such inquiries, proposals or offers
received by, any such information requested from, or any such discussions or
negotiations sought to be initiated or continued with Coast or any Subsidiary
thereof. Coast shall immediately cease and cause to be terminated any
activities, discussions or negotiations conducted prior to the date of this
Agreement with any parties other than Ahmanson with respect to any of the
foregoing and shall use its reasonable best efforts to enforce any
confidentiality or similar agreement relating to an Acquisition Proposal. Coast
shall promptly (within 24 hours) advise Ahmanson following the receipt by Coast
of any Acquisition Proposal and the substance thereof (including the identity of
the person making such Acquisition Proposal), and advise Ahmanson of any
developments with respect to such Acquisition Proposal immediately upon the
occurrence thereof.

        6.07 Affiliate Agreements. (a) Not later than the 15th day prior to the
mailing of the Proxy Statement, Coast shall deliver to Ahmanson a schedule of
each person that, to the best of its knowledge, is or is reasonably likely to
be, as of the date of the Coast Meeting, deemed to be an "affiliate" of Coast
(each, a "Coast Affiliate") as that term is used in Rule 145 under the
Securities Act or SEC Accounting Series Releases 130 and 135.

        (b) Coast shall use its reasonable best efforts to cause each person who
    may be deemed to be a Coast Affiliate to execute and deliver to Ahmanson on
    or before the date of mailing of the Proxy Statement an agreement in the
    form attached hereto as Exhibit A.

        6.08 Takeover Laws. No party hereto shall take any action that would
cause the transactions contemplated by this Agreement to be subject to
requirements imposed by any Takeover Law and each of them shall take all
necessary steps within its control to exempt (or ensure the continued exemption
of) the transactions contemplated by this Agreement from, or if necessary
challenge the validity or applicability of, any applicable Takeover Law, as now
or hereafter in effect.

        6.09 Certain Policies. Prior to the Effective Date, Coast shall,
consistent with generally accepted accounting principles and on a basis mutually
satisfactory to it and Ahmanson, modify and change its loan, litigation and real
estate valuation policies and practices (including loan classifications and
levels of reserves) so as to be applied on a basis that is consistent with that
of Ahmanson; provided, however, that Coast shall not be obligated to take any
such action pursuant to this Section 6.09 unless and until Ahmanson acknowledges
that all conditions to its obligation to consummate the Merger have been
satisfied.

        6.10 NYSE Listing. Ahmanson agrees to use its reasonable best efforts to
list, prior to the Effective Date, on the NYSE, subject to official notice of
issuance, the shares of Ahmanson Common Stock to be issued to the holders of
Coast Common Stock in the Merger.

        6.11 Regulatory Applications. (a) Ahmanson and Coast and their
respective Subsidiaries shall cooperate and use their respective reasonable best
efforts to prepare all documentation, to effect all filings and to obtain all
permits, consents, approvals and authorizations of all third parties and
Governmental Authorities necessary to consummate the transactions contemplated
by this Agreement. Each of Ahmanson and Coast shall have the right to review in
advance, and to the extent practicable each will consult with the other, in each
case subject to applicable laws relating to the exchange of information, with
respect to all material written information submitted to any third party or any
Governmental Authority in connection with the transactions contemplated by this
Agreement. In exercising the foregoing right, each of the parties hereto agrees
to act reasonably and as promptly as practicable. Each party hereto agrees that
it will consult with the other party hereto with respect to the obtaining of all
material permits, consents, approvals and authorizations of all third parties
and Governmental Authorities necessary or advisable to consummate the
transactions contemplated by this Agreement and each party will keep the other
party appraised of the status of material matters relating to completion of the
transactions contemplated hereby.

<PAGE>   113



        (b) Each party agrees, upon request, to furnish the other party with all
    information concerning itself, its Subsidiaries, directors, officers and
    stockholders and such other matters as may be reasonably necessary or
    advisable in connection with any filing, notice or application made by or on
    behalf of such other party or any of its Subsidiaries to any third party or
    Governmental Authority.

        6.12 Indemnification. (a) Following the Effective Date, Ahmanson shall
indemnify, defend and hold harmless the present directors and officers of Coast
and its Subsidiaries (each, an "Indemnified Party") against all costs or
expenses (including reasonable attorneys' fees), judgments, fines, losses,
claims, damages or liabilities (collectively, "Costs") as incurred, in
connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of actions or
omissions occurring at or prior to the Effective Time (including, without
limitation, the transactions contemplated by this Agreement) to the fullest
extent that Coast is permitted to indemnify (and advance expenses to) its
directors and officers under the laws of the State of Delaware, the Coast
Certificate and the Coast By-Laws as in effect on the date hereof; provided that
any determination required to be made with respect to whether an officer's or
director's conduct complies with the standards set forth under Delaware law, the
Coast Certificate and the Coast By-Laws shall be made by independent counsel
(which shall not be counsel that provides material services to Ahmanson)
selected by Ahmanson and reasonably acceptable to such officer or director.

        (b) For a period of four years from the Effective Time, Ahmanson shall
    use its reasonable best efforts to provide that portion of director's and
    officer's liability insurance that serves to reimburse the present and
    former officers and directors of Coast or any of its Subsidiaries
    (determined as of the Effective Time) (as opposed to Coast) with respect to
    claims against such directors and officers arising from facts or events
    occurring at or prior to the Effective Time (including the transactions
    contemplated by this Agreement) which insurance shall contain at least the
    same coverage and amounts, and contain terms and conditions no less
    advantageous, as that coverage currently provided by Coast; provided,
    however, that in no event shall Ahmanson be required to expend more than
    200% of the Previously Disclosed current amount expended by Coast (the
    "Insurance Amount") to maintain or procure such directors and officers
    insurance coverage; provided, further, that if Ahmanson is unable to
    maintain or obtain the insurance called for by this Section 6.12(b),
    Ahmanson shall use its reasonable best efforts to obtain as much comparable
    insurance as is available for the Insurance Amount; provided, further, that
    officers and directors of Coast or any Subsidiary may be required to make
    application and provide customary representations and warranties to
    Ahmanson's insurance carrier for the purpose of obtaining such insurance.

        (c) Any Indemnified Party wishing to claim indemnification under Section
    6.12(a), upon learning of any claim, action, suit, proceeding or
    investigation described above, shall promptly notify Ahmanson thereof;
    provided that the failure so to notify shall not affect the obligations of
    Ahmanson under Section 6.12(a) unless and to the extent that Ahmanson is
    actually prejudiced as a result of such failure.

        (d) If Ahmanson or any of its successors or assigns shall consolidate
    with or merge into any other entity and shall not be the continuing or
    surviving entity of such consolidation or merger or shall transfer all or
    substantially all of its assets to any other entity, then and in each case,

        6.15 Notification of Certain Matters. Each of Coast and Ahmanson shall
give prompt notice to the other of any fact, event or circumstance known to it
that (i) is reasonably likely, individually or taken together with all other

provided, however, that Coast shall not be required to cause the CPR Trust to
issue such CPR Certificates or be required to so distribute the CPR Certificates
until all conditions to the Merger, other than such distribution, have been
satisfied or waived. Except as set forth in this Section, the terms of the CPR
Trust and the CPR Certificates shall be as set forth in Annex I. Coast agrees to
cause the CPR Trust immediately prior to the Effective Time to deliver to Coast
a number of CPR Certificates sufficient for the delivery of CPR Certificates
required pursuant to Section 3.06. Ahmanson agrees to return to the CPR Trust
any CPR Certificates with respect to Replacement Options that expire prior to
exercise.

<PAGE>   115



    engagement) and the terms of the Commitment and the rights of holders of
    Trust Certificates) and the Merger shall have been duly adopted by the
    requisite vote of the stockholders of Coast.

    consummate the transactions contemplated hereby, shall have been obtained
    and shall remain in full force and effect and all statutory waiting periods
    in respect thereof shall have expired and no such approvals shall contain
    any conditions, restrictions or requirements which would reasonably be
    expected to (i) following the Effective Time, have a Material Adverse Effect
    on the Surviving Corporation and its Subsidiaries taken as a whole or (ii)
    reduce the benefits of the transactions contemplated hereby to such a degree
    that Ahmanson would not have entered into this Agreement had such
    conditions, restrictions or requirements been known at the date hereof.

        (c) No Injunction. No Governmental Authority of competent jurisdiction
    shall have enacted, issued, promulgated, enforced or entered any statute,
    rule, regulation, judgment, decree, injunction or other order (whether

    Statements shall have become effective under the Securities Act and no stop
    order suspending the effectiveness of the Registration Statements shall have
    been issued and be in effect and no proceedings for that purpose shall have
    been initiated or threatened by the SEC and not withdrawn. If required, the
    Trust Agreement shall have been duly qualified under the Trust Indenture

    Merger shall have been approved for listing on the NYSE, subject to official
    notice of issuance.

consummate the Merger is also subject to the fulfillment or written waiver by
Coast prior to the Effective Time of each of the following conditions:

        (c) Opinion of Coast's Counsel. Coast shall have received an opinion of
    Cleary, Gottlieb, Steen & Hamilton, special counsel to Coast, dated the
    Effective Date, to the effect that, on the basis of facts, representations
    and assumptions set forth in such opinion, (A) the Merger constitutes a
    "reorganization" within the meaning of Section 368 of the Code that,
    accordingly, (i) no gain or loss will be recognized by Coast as a result of
    the Merger and (ii) no gain or loss will be recognized by a stockholder of
    Coast who receives shares of Ahmanson Common Stock in exchange for shares of
    Coast Common Stock, except (x) with respect to cash received in lieu of
    fractional share interests and (y) for gain that may be recognized in an
    amount not exceeding the fair market value at the time of the Merger of such
    stockholder's CPR Certificates (which represent such stockholder's share of
    the Commitment Amount), and (B) the CPR Trust will not itself be subject to
    any material federal income taxes. In rendering its opinion, such counsel
    may require and rely upon representations contained in letters from Coast,
    Ahmanson and stockholders of Coast. The foregoing opinion will not apply to
    stockholders or persons receiving Ahmanson Common Stock or CPR Certificates
    as compensation.

<PAGE>   117



    contained herein, which breach cannot be or has not been cured within 20

    Agreement.

        (d) No Approval. By Coast or Ahmanson, if its Board of Directors so

liability for any breach of this Agreement giving rise to such termination.

        (b) If (a) this Agreement shall be terminated (i) by Ahmanson pursuant
    to Section 8.01(b) or Section 8.01(e) and, at the time of the occurrence of
    the circumstance permitting termination pursuant to such Section, there
    shall exist an Acquisition Proposal with respect to Coast or any of its
    Subsidiaries, or (ii) by Coast pursuant to Section 8.01(d)(ii) and, at the
    time of the occurrence of the circumstance permitting termination pursuant

               SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW
                                APPRAISAL RIGHTS.

    (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to ss.228 of this
title shall be entitled to an appraisal by the Court of Chancery of the fair
value of the stockholder's shares of stock under the circumstances described in
subsections (b) and (c) of this section. As used in this section, the word
"stockholder" means a holder of record of stock in a stock corporation and also
a member of record of a nonstock corporation; the words "stock" and "share" mean
and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.

    (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to ss.251 (other than a merger effected pursuant to ss.251(g)
of this title), ss.252, ss.254, ss.257, ss.258, ss.263 or ss.264 of this title:

        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent
    corporation surviving a merger if the merger did not require for its
    approval the vote of the stockholders of the surviving corporation as
    provided in subsection (f) of ss.251 of this title.

        (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to ss.ss.251,
    252, 254, 257, 258, 263 and 264 of this title to accept for such stock
    anything except:

            a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

            b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depositary receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

            c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

            d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.


                                       E-1

<PAGE>   124



        (3) In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under ss.253 of this title is not owned by the
    parent corporation immediately prior to the merger, appraisal rights shall
    be available for the shares of the subsidiary Delaware corporation.

    (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

    (d) Appraisal rights shall be perfected as follows:

        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsections (b) or (c) hereof that appraisal rights are
    available for any or all of the shares of the constituent corporations, and
    shall include in such notice a copy of this section. Each stockholder
    electing to demand the appraisal of his shares shall deliver to the
    corporation, before the taking of the vote on the merger or consolidation, a
    written demand for appraisal of his shares. Such demand will be sufficient
    if it reasonably informs the corporation of the identity of the stockholder
    and that the stockholder intends thereby to demand the appraisal of his
    shares. A proxy or vote against the merger or consolidation shall not
    constitute such a demand. A stockholder electing to take such action must do
    so by a separate written demand as herein provided. Within 10 days after the
    effective date of such merger or consolidation, the surviving or resulting
    corporation shall notify each stockholder of each constituent corporation
    who has complied with this subsection and has not voted in favor of or
    consented to the merger or consolidation of the date that the merger or
    consolidation has become effective; or

        (2) If the merger or consolidation was approved pursuant to ss.228 or
    253 of this title, each constituent corporation, either before the effective
    date of the merger or consolidation or within ten days thereafter, shall
    notify each of the holders of any class or series of stock of such
    constituent corporation who are entitled to appraisal rights of the approval
    of the merger or consolidation and that appraisal rights are available for
    any or all shares of such class or series of stock of such constituent
    corporation, and shall include in such notice a copy of this section;
    provided that, if the notice is given on or after the effective date of the
    merger or consolidation, such notice shall be given by the surviving or
    resulting corporation to all such holders of any class or series of stock of
    a constituent corporation that are entitled to appraisal rights. Such notice
    may, and, if given on or after the effective date of the merger or
    consolidation, shall, also notify such stockholders of the effective date of
    the merger or consolidation. Any stockholder entitled to appraisal rights
    may, within 20 days after the date of mailing of such notice, demand in
    writing from the surviving or resulting corporation the appraisal of such
    holder's shares. Such demand will be sufficient if it reasonably informs the
    corporation of the identity of the stockholder and that the stockholder
    intends thereby to demand the appraisal of such holder's shares. If such
    notice did not notify stockholders of the effective date of the merger or
    consolidation, either (i) each such constituent corporation shall send a
    second notice before the effective date of the merger or consolidation
    notifying each of the holders of any class or series of stock of such
    constituent corporation that are entitled to appraisal rights of the
    effective date of the merger or consolidation or (ii) the surviving or
    resulting corporation shall send such a second notice to all such holders on
    or within 10 days after such effective date; provided, however, that if such
    second notice is sent more than 20 days following the sending of the first
    notice, such second notice need only be sent to each stockholder who is
    entitled to appraisal rights and who has demanded appraisal of such holder's
    shares in accordance with this subsection. An affidavit of the secretary or
    assistant secretary or of the transfer agent of the corporation that is
    required to give either notice that such notice has been given shall, in the
    absence of fraud, be prima facie evidence of the facts stated therein. For
    purposes of determining the stockholders entitled to receive either notice,
    each constituent corporation may fix, in advance, a record date that shall
    be not more than 10 days prior to the date the notice is given, provided,
    that if the notice is given on or after the effective date of the merger or
    consolidation, the record date shall be such


                                       E-2

<PAGE>   125



    effective date. If no record date is fixed and the notice is given prior to
    the effective date, the record date shall be the close of business on the
    day next preceding the day on which the notice is given.

    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw his demand for
appraisal and to accept the terms offered upon the merger or consolidation.
Within 120 days after the effective date of the merger or consolidation, any
stockholder who has complied with the requirements of subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the corporation
surviving the merger or resulting from the consolidation a statement setting
forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after his written request for such a
statement is received by the surviving or resulting corporation or within 10
days after expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.

    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

    (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

    (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.

    (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and


                                       E-3

<PAGE>   126



the case of holders of shares represented by certificates upon the surrender to
the corporation of the certificates representing such stock. The Court's decree
may be enforced as other decrees in the Court of Chancery may be enforced,
whether such surviving or resulting corporation be a corporation of this State
or of any state.

    (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

    (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

                        INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    As permitted by Section 102(b)(7) of the DGCL, Article Sixteenth of the
Ahmanson Charter (Exhibit 4.2 hereto) eliminates the monetary liability of a
director to the corporation or its stockholders for breach of fiduciary duty as
a director, with the following exceptions, as required by Delaware law: (i)
breach of the director's duty of loyalty to the corporation or its stockholders;
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law; (iii) payment of unlawful dividends or making
unlawful stock purchases or redemptions; or (iv) transactions from which the
director derived an improper personal benefit.

    In addition, under Section 145 of the DGCL, a corporation may indemnify a
director, officer, employee or agent of the corporation against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with any threatened,
pending or completed Proceeding (other than an action by or in the right of the
corporation) if he acted in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the corporation and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. In the case of an action brought by or in the
right of the corporation, the corporation may indemnify a director, officer,
employee or agent of the corporation against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection with the defense or
settlement of any threatened, pending or completed action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the corporation unless and only to the extent that a
court determines upon application that, in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses as the court deems proper. Article VII of the Ahmanson By-laws (Exhibit
4.3 hereto) provides for indemnification of its directors, officers, employees,
and other agents to the fullest extent permitted by the DGCL.

    Ahmanson has insured its liability where indemnification of its directors
and officers is proper under the foregoing provisions of the Ahmanson Charter
and the Ahmanson By-laws up to an aggregate of $55,000,000.

ITEM 22.  UNDERTAKINGS.

      (a) The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being 
made, a post-effective amendment to this Registration Statement;

              (i) To include any Prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

              (ii) To reflect in the Prospectus any facts or events arising
          after the effective date of the Registration Statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the Registration Statement;

              (iii) To include any material information with respect to the plan
          of distribution not previously disclosed in the Registration Statement
          or any material change to such information in the Registration
          Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

                                        II-2


<PAGE>   129



         (4) That prior to any public reoffering of the securities registered
hereunder through use of a Prospectus which is a part of this Registration
Statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), the Registrant undertakes that such reoffering
Prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other Items of
the applicable form.

         (5) That every Prospectus (a) that is filed pursuant to paragraph (4)
immediately preceding, or (b) that purports to meet the requirements of Section
10(a)(3) of the Securities Act of 1933 and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (6) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions (See Item 20), or
otherwise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

      (b) The undersigned Registrant hereby undertakes to respond to requests 
for information that is incorporated by reference into the Prospectus pursuant
to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.

      (c) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
