           COAST FEDERAL LITIGATION CONTINGENT PAYMENT RIGHTS TRUST

                         PART I  FINANCIAL INFORMATION



Item 1.  Not applicable

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
         AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the Registration
Statement on Form S-1 with respect to the CPR Certificates referred to herein
filed by Coast Savings Financial, Inc. ("Coast") with, and declared effective
by, the Securities and Exchange Commission (the "SEC") on January 13, 1998 (SEC
File Number 333-44155).

GENERAL

The Coast Federal Litigation Contingent Payment Rights Trust (the "CPR Trust")
is a statutory business trust created under Delaware law on January 8, 1998. The
CPR Trust was created by Coast in connection with its merger, effected on
February 13, 1998 (the "Merger"), with and into H. F. Ahmanson & Co.
("Ahmanson"), for the purpose of holding the Commitment Agreement entered into
by Ahmanson and the CPR Trust, dated as of February 13, 1998 (the "Commitment").
The Commitment represents Ahmanson's obligation to pay to the CPR Trust an
amount equal to any net after-tax proceeds, as more particularly defined in the
CPR Trust Agreement referred to below (the "Commitment Amount"), that may be
received by Coast's wholly-owned subsidiary, Coast Federal Savings, FSB ("Coast
Federal") (or its successor), from Coast Federal's regulatory capital litigation
claims against the United States government in the case entitled Coast Federal
                                                                 -------------
Bank. FSB v. United States, No. 92-466C (Cl. Ct. filed July 9, 1992) (the
--------------------------                                               
"Litigation"). Subsequent to the merger, Ahmanson merged Coast Federal with and
into Ahmanson's wholly-owned subsidiary, Home Savings of America, FSB ("Home
Savings"), with Home Savings as being the successor institution.

The governing instrument of the CPR Trust is the Amended and Restated
Declaration of Trust, dated as of February 13, 1998 (the "CPR Trust Agreement")
entered into among Coast, the Litigation Trustees, Bankers Trust Company (the
"Institutional Trustee") and Bankers Trust (Delaware) (the "Delaware Trustee").
Pursuant to the CPR Trust Agreement, the four senior executives of Coast with
knowledge of the facts underlying the Litigation were appointed as "Litigation
Trustees" of the CPR Trust, and were given full authority to make all decisions
on behalf of Coast Federal (and its successors) with respect to the prosecution
and resolution of the Litigation.

The assets of the CPR Trust consist solely of the Commitment and the right to
draw on amounts in the Expense Fund for purposes of funding expenses of the CPR
Trust, including expenses of the Litigation, fees and expenses of the Litigation
Trustees and all administrative expenses. Under the CPR Trust Agreement,
Ahmanson agreed to provide the sum of $19,884,294 (which is equal to $20 million
less expenses related to the Litigation incurred by Coast Federal between
September 1, 1997

                                       1
<PAGE>
 
and February 13, 1998) (the "Expense Fund") to fund the Litigation and other
expenses of the CPR Trust, which amount is to be reimbursed to Ahmanson from any
proceeds of the Litigation, including any amounts received in settlement of the
Litigation, prior to the payment of any amounts to holders of the CPR
Certificates. The Expense Fund is on deposit in a non-interest bearing demand
deposit account established by Ahmanson in the name of the CPR Trust at Home
Savings.

Within 60 days of the receipt of any Commitment Amount, the CPR Trust is
required under the CPR Agreement to pay such amounts (other than $10 million, or
such greater amount as the Litigation Trustees reasonably determine may be
reasonably likely to be required, to pay additional expenses or to satisfy the
CPR Trust's indemnification obligations (the "Retained Amount")) less the amount
of any accrued but unpaid expenses payable by the CPR Trust but not covered by
the Expense Fund, to the holders of the CPR Certificates as of a record date to
be set by the Litigation Trustees. The Retained Amount will be retained for a
period of two years, or such longer period as the Litigation Trustees reasonably
determine may be required.

The Litigation Trustees on behalf of the CPR Trust maintain an office at 136
South Oak Knoll Avenue, Suite 320, Pasadena, California 91101, for the purpose
of pursuing the Litigation and administering their other duties under the CPR
Trust Agreement.

THE LITIGATION

The following description of the Litigation does not purport to be a complete
description of the legal and factual issues presented, the court opinions
rendered or the relevant law, and the description is in all respects qualified
by reference to the documents filed in the Litigation, such opinions and the
relevant law.

On July 9, 1992, Coast Federal commenced litigation entitled Coast Federal Bank,
Federal Savings Bank v. United States, Civil Action Number 92-466C, against the
United States in the U.S. Claims Court (now the U.S. Court of Federal Claims,
the "Claims Court") alleging that the United States is in breach of contract
with Coast Federal and has unlawfully taken Coast Federal's property without
just compensation or due process of law in violation of the U.S. Constitution.
Coast Federal's claims arose from changes, mandated by FIRREA and certain
regulations promulgated thereunder, with respect to the rules for computing
Coast Federal's regulatory capital.

On April 10, 1987, Coast Federal acquired substantially all of the assets and
liabilities of Central Savings and Loan Association ("Central") from the Federal
Savings and Loan Insurance Corporation (the "FSLIC") in a supervisory
transaction (the "Acquisition") that Coast Federal alleges was induced and
arranged by the FSLIC and the Federal Home Loan Bank Board ("FHLBB"). As part of
the Acquisition, Coast Federal entered into a contract with the FSLIC (the
"Assistance Agreement") under which the FSLIC made a cash contribution to Coast
Federal in the amount of $298.3 million (the "Capital Credit"). In the
Litigation, Coast Federal alleges that the Assistance Agreement and certain
resolutions and a forbearance letter issued by the FHLBB in connection with the
Assistance Agreement each expressly provided that the Capital Credit was to be
treated as a permanent addition to

                                       2
<PAGE>
 
Coast Federal's regulatory capital. Coast Federal further alleges that such
treatment of the Capital Credit for regulatory capital purposes was essential to
inducing Coast Federal to consummate the Acquisition.

Pursuant to FIRREA, which became effective on August 9, 1989, the FSLIC and the
FHLBB were eliminated and were replaced as the regulators of federally insured
thrift institutions by the Office of Thrift Supervision (the "OTS"). In
regulations implementing FIRREA (the "Capital Regulations") and subsequent
actions, the OTS took the position that the Capital Credit should be classified
as supervisory goodwill, as defined in the Capital Regulations, which action
resulted in an immediate exclusion of the Capital Credit from one of the three
measures of Coast Federal's regulatory capital and effected a five year phase-
out of the Capital Credit from such inclusion in the other two measures.

Coast Federal alleges that FIRREA and the Capital Regulations constituted a
breach by the United States of its contractual commitment regarding the
regulatory capital treatment of the Capital Credit and an unlawful taking of
Coast Federal's property rights in the Capital Credit. Coast Federal seeks
damages for such breach by the United States of the alleged contract.

RELATED CASES

The Litigation is one of a number of cases filed against the federal government
in the Claims Court involving acquisitions of failed savings institutions and
alleging that the changes in regulatory capital calculation brought about by
FIRREA and the Capital Regulations constitute a breach of the contract between
the acquiring institution and the federal government. For purposes of the
administration of such claims, the Claims Court bifurcated the trial proceedings
in the first three of such cases to be heard by it (Winstar Corporation, et al.
v. United States, Docket No. 90-8C; Statesman Savings Holding Corp., et al. v.
United States, Docket No. 90-773C (the "Statesman Case"); and Glendale Federal
Bank v. United States, Docket No. 90-772C (the "Glendale Case"), which cases are
collectively referred to herein as the "Related Cases").  In July 1992, the
Claims Court ruled in favor of the plaintiffs in the Related Cases on the
initial liability question, finding in each case that the plaintiff had a
contract as alleged with the federal government and that the federal government
is in breach of that contract as a result of the enactment of FIRREA and the
issuance of the Capital Regulations thereunder. The decision of the Claims Court
on liability was appealed by the federal government. After extended appellate
proceedings, culminating in an appeal to the Supreme Court, the Supreme Court
ruled in favor of the plaintiffs in the Related Cases in United States v.
Winstar Corp., et al., No. 95-865 (the "Winstar Case").

The Glendale Case is currently in trial on the issue of damages resulting from
the United States' breach of contract, with final arguments scheduled for
September, 1998, and the Statesman Case is scheduled to begin trial on the same
issue on May 18, 1998. In an attempt to manage the numerous cases against the
federal government involving the calculation of regulatory capital as a result
of the adoption of FIRREA, the Claims Court has determined that no other case,
including the Litigation, will go to trial until the damages trials in

                                       3
<PAGE>
 
both the Glendale Case and the Statesman Case have been completed. In addition,
the Claims Court has designated twelve cases as priority cases (the "Priority
Cases") which will be the first cases to go to trial following the trials on
damages in the Glendale Case and the Statesman Case. The first of the Priority
Cases is expected to begin trial in late 1998 or early 1999. The Litigation is
scheduled to be among the first group of thirty cases to go to trial following
completion of trial in the Priority Cases.

LIABILITY

The Claims Court stayed proceedings in each of the other cases against the
federal government, including the Litigation, pending the outcome of
the liability phase of the Related Cases. Subsequent to the Supreme Court's
decision in the Winstar Case in July of 1996, such stay was lifted and Coast
reinstated its motion for partial summary judgment as to the federal
government's liability, which had been pending since March of 1993. On February
20, 1998 the United States filed its response to Coast Federal's motion. In its
response, the Government stated that "at this point, entry of an order regarding
the Government's liability would be appropriate. We believe that such an order
should reflect the Government's concession that a contract existed with respect
to Coast's claim for a capital credit to its net worth, and that the Government
acted inconsistently with the contract."   On March 23, 1998, Chief Judge Loren
A. Smith entered an order in the Litigation granting Coast Federal's motion for
partial summary judgment as to liability with respect to the Coast Federal's
claim for a capital credit to its net worth.

DAMAGES

Although Coast Federal has conducted preliminary reviews of the damages it
believes it suffered as a result of the Government's actions, no conclusive
determinations have been made regarding the amount or type of such damages. Each
savings institution affected by FIRREA's and the Capital Regulations' limitation
on the inclusion in regulatory capital of supervisory goodwill or FSLIC capital
contributions reacted to the resulting reduction in their regulatory capital in
an individual fashion dictated by the unique facts and circumstances faced by
the institution. Accordingly, the extent and amount of damages awarded to each
such institution that has brought an action against the federal government is
expected to be fact specific. Even if the plaintiffs in the Related Cases are
successful in securing damage awards, there can be no assurance that Coast
Federal will obtain a damage award.

The United States has argued in the Related Cases that some or all of the
damages alleged by the plaintiffs in the Related Cases are too speculative to
permit a recovery. Any trial of Coast Federal's damage claims will occur after
the trial of the damage phases of two of the Related Cases, and rulings in the
Related Cases may adversely affect some or all of Coast Federal's damage claims.
In addition, the Priority Cases are scheduled for trial before the damages phase
of Coast Federal's case is likely to go to trial, and rulings in those cases may
also adversely affect some or all of Coast Federal's damage claims. For these
and related reasons, there can be no assurance as to the amount, if any, and
type of damages that Coast Federal may recover. Without

                                       4
<PAGE>
 
limiting the generality of the foregoing, there can be no assurance that Coast
Federal will obtain any monetary recovery in the Litigation.

MANAGEMENT OF THE LITIGATION

Pursuant to the CPR Trust Agreement, the Litigation Trustees have sole and
exclusive right to instruct Coast Federal and its successors with respect to the
prosecution of the Litigation (including all decisions as to retention,
dismissal and the terms of engagement of existing or new counsel for Coast
Federal, which retention may involve fees that are partly contingent, and other
advisors), and Ahmanson is required to cause Coast Federal and its successors to
follow such instructions other than instructions that are not reasonable.

The Litigation Trustees have entered into a letter agreement with the law firm
which has prosecuted the Litigation to date, Cooper, Carvin & Rosenthal (the
"Firm"), dated February 13, 1998 (the "Letter Agreement"), pursuant to which the
Firm agrees that it will not bill Coast Federal or the CPR Trust for any fees
incurred subsequent to September 1, 1997 in excess of $7,650,000 (the "Cap"). In
addition, up to $2 million of the Cap, i.e., any amounts over $5,650,000, will
only be payable to the Firm out of the Commitment Amount, if any, when received
by the CPR Trust from Ahmanson. In consideration of such limitations on the
Firm's customary charges for professional services, the Letter Agreement
provides that the CPR Trust will pay to the Firm, in addition to the Cap, a
contingent incentive fee in the amount of one percent (1%) of the Commitment
Amount, provided that no such incentive fee shall be payable in the events (1)
that both Charles J. Cooper and Steven S. Rosenthal shall cease to be a partner
of the Firm prior to a final decision, including appeals, or other final
resolution of the Litigation, or (2) that either Mr. Cooper or Mr. Rosenthal
shall cease to be a partner of the Firm prior to a final decision, including any
appeals, or other final resolution of the Litigation, other than by death,
disability, or appointment to federal office.

The CPR Trust Agreement also provides that the Litigation Trustees have the
right, in their sole discretion, to instruct Coast Federal and its successors to
dismiss, settle or cease prosecution of the Litigation at any time and on any
terms, and Ahmanson is required by the CPR Trust Agreement to cause Coast
Federal and its successors to follow such instructions other than instructions
that are not reasonable.

The CPR Trust Agreement provides 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 the remainder of such year plus two additional years) 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 shall be entitled to a fee of $200 per hour
until termination of the CPR Trust. Pursuant to the CPR Trust Agreement, each
Litigation Trustee may, but is not obligated to, defer all or part of his
compensation until 30 days after the earliest to occur of (i) the date on which
he elected to defer such

                                       5
<PAGE>
 
compensation, (ii) the date he ceases to be a Litigation Trustee, and (iii) the
date of the receipt of the Commitment Amount in full by the CPR Trust. Any
Litigation Trustee electing to so defer will receive the compensation he would
have received plus an amount, calculated on a monthly basis during the period of
deferral (and included in the amount deferred), equal to the product of the
monthly balance of the amount deferred and an annual rate equal to the Reference
Rate, as defined in the CPR Trust Agreement, plus 250 basis points. For the year
ending December 31, 1998, Mr. Martin, Mr. Hunt, Mr. Barritt and Mr. Raiden have
elected to defer one-half of their 1998 compensation.

SUMMARY FINANCIAL INFORMATION

The CPR Trust has no revenues.  The Expense Fund is the CPR Trust's only source
of funding for payment of expenses and operations.  Following is a statement
that details the activity in the Expense Fund and expenses that have been
accrued but not yet paid for the quarter ended March 31, 1998, as well as the
balance of the Expense Fund that was available for payment of future expenses as
of March 31, 1998.

</TABLE> 

In addition, $7,984 of expenses were accrued during the quarter ended March 31,
1998, for interest payable to Ahmanson on disbursements from the Expense Fund.
Payment of such accrued interest payable is contingent upon receipt of the
Commitment Amount.

Expenses for "Litigation and trust administration" refer to fees paid to three
individuals retained by the CPR Trust to provide litigation and trust
administration support services. The expenditure of insurance includes
$1,000,000 for a single premium policy of indemnity insurance for the life of
the CPR Trust.

The amounts in the Expense Fund will be applied to a variety of expenses,
including the costs of prosecuting the Litigation (including the fees and
expenses of counsel, experts, support staff and consultants), compensation of
the Institutional Trustee, the Delaware Trustee and the Litigation Trustees, the
CPR Trust's indemnification obligations (see "The CPR Certificates
Indemnification Obligations of the CPR Trust; Liability Insurance") and
liability insurance for the CPR Trust's indemnification obligations and any
liabilities of the

                                       6
<PAGE>
 
Litigation Trustees. To the extent that Coast Federal and its successors must
engage in protracted litigation, such fees and expenses may increase
significantly, and there is no assurance that the Expense Fund will be
sufficient to cover such fees and expenses.

The CPR Trust may issue additional CPR Certificates that represent pro rata
interests in the assets of the CPR Trust in order to pay expenses. However, it
may not be possible to obtain purchasers of the additional CPR Certificates and
there is no assurance that the terms of any such purchases would be reasonable.
In the event additional CPR Certificates are issued and existing CPR Certificate
holders are not given the opportunity to purchase, or do not purchase a pro rata
amount in such issuance, such CPR Certificate holders' indirect interest in  the
Payment Amount will be diluted. The CPR Trust will be authorized to borrow
additional funds for the sole purpose of funding expenses of the CPR Trust, but
only if such borrowings represent debt of the CPR Trust (and not ownership
interests) for federal income tax purposes. Furthermore, it may not be possible
for the CPR Trust to borrow funds (and, if it is able to borrow funds, there can
be no assurance as to the terms upon which such borrowings may be available).
