                               WILLIAM LYON HOMES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

NOTE 1 -- BASIS OF PRESENTATION

     William Lyon Homes, a Delaware corporation and subsidiaries (the "Company")
are primarily engaged in designing, constructing and selling single family
detached and attached homes in California, Arizona and Nevada.

     The unaudited consolidated financial statements of the Company have been
prepared in accordance with accounting principles generally accepted in the
United States for interim financial information and in accordance with the rules
and regulations of the Securities and Exchange Commission. The consolidated
financial statements do not include all of the information and footnotes
required by accounting principles generally accepted in the United States for
complete financial statements. The consolidated financial statements included
herein should be read in conjunction with the Company's Annual Report on Form
10-K for the year ended December 31, 2000.

     The interim consolidated financial statements have been prepared in
accordance with the Company's customary accounting practices. In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a presentation in accordance with accounting principles generally
accepted in the United States have been included. Operating results for the
three and six months ended June 30, 2001 are not necessarily indicative of the
results that may be expected for the year ending December 31, 2001.

     The consolidated financial statements include the accounts of the Company
and all majority-owned subsidiaries and joint ventures. Investments in joint
ventures in which the Company has a 50% or less ownership interest are accounted
for using the equity method. The accounting policies of the joint ventures are
substantially the same as those of the Company. All significant intercompany
accounts and transactions have been eliminated in consolidation.

     The Company designs, constructs and sells a wide range of homes designed to
meet the specific needs of each of its markets. For internal reporting purposes,
the Company is organized into five geographic home building regions and its
mortgage origination operation. Because each of the Company's geographic home
building regions has similar economic characteristics, housing products and
class of prospective buyers, the geographic home building regions have been
aggregated into a single home building segment.

     The Company evaluates performance and allocates resources primarily based
on the gross margin and operating income of individual home building projects.
Gross margin is defined by the Company as home sales less cost of sales.
Operating income is defined by the Company as sales of homes, lots and land and
management fee income; less cost of sales, impairment losses on real estate,
selling and marketing, general and administrative expenses and amortization of
goodwill. Accordingly, both gross margin and operating income exclude certain
items included in the determination of net income. All other segment
measurements are disclosed in the Company's Annual Report on Form 10-K for the
year ended December 31, 2000.

     Management fee income represents income recognized in the current period
from unconsolidated joint ventures in accordance with joint venture and/or
operating agreements. Such fees are reimbursements of overhead expenses incurred
by the Company as the managing partner or member of the unconsolidated joint
ventures.

     The amount paid for business acquisitions over the net fair value of assets
acquired and liabilities assumed is reflected as goodwill and is being amortized
on a straight-line basis over seven years. Accumulated amortization was
$1,551,000 and $2,172,000 as of December 31, 2000 and June 30, 2001,
respectively. In June 2001, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 142, Goodwill and Other
Intangible Assets ("Statement No. 142"), effective for fiscal years beginning
after December 15, 2001. Under the new rule, goodwill will no longer be
amortized but will be subject to

                                  (UNAUDITED)

annual impairment tests in accordance with Statement No. 142. The Company will
apply the new rule on accounting for goodwill beginning in the first quarter of
2002. Application of the nonamortization provisions of Statement No. 142 is
expected to result in an increase in net income of $1,110,000 ($0.10 per share)
per year. During 2002, the Company will perform the first of the required
impairment tests of goodwill as of January 1, 2002 and has not yet determined
what the effect of these tests will be on the earnings and financial position of
the Company.

     Earnings per share amounts for all periods presented conform to Financial
Accounting Standards Board Statement No. 128, "Earnings Per Share." Basic and
diluted earnings per common share for the three months ended June 30, 2001 are
based on 10,576,048 and 10,723,811 weighted average shares of common stock
outstanding, respectively. Basic and diluted earnings per common share for the
six months ended June 30, 2001 are based on 10,573,152 and 10,684,244 weighted
average shares of common stock outstanding, respectively. Both basic and diluted
earnings per common share for the three and six months ended June 30, 2000 are
based on 10,465,692 and 10,452,414 shares of common stock outstanding,
respectively.

     The preparation of the Company's financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the reported amounts of
the assets and liabilities as of June 30, 2001 and December 31, 2000 and
revenues and expenses for the periods presented. Accordingly, actual results
could differ materially from those estimates in the near-term.

     The Company completed a capital restructuring and quasi-reorganization
which resulted in the adjustment of assets and liabilities to their estimated
fair values effective January 1, 1994. Income tax benefits resulting from the
utilization of net operating losses and other carryforwards existing at January
1, 1994 and temporary differences existing prior to or resulting from the
quasi-reorganization ("quasi-reorganization income tax benefits") have been
excluded from the results of operations and credited to paid-in capital. As of
December 31, 2000, all quasi-reorganization income tax benefits have been fully
utilized.

NOTE 2 -- INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED JOINT VENTURES

     The Company and certain of its subsidiaries are general partners or members
in joint ventures involved in the development and sale of residential projects.
Such joint ventures are 50% or less owned and, accordingly, the financial
statements of such joint ventures are not consolidated with the Company's
financial statements. The Company's investments in unconsolidated joint ventures
are accounted for using the equity method. Condensed combined financial
information of these joint ventures as of June 30, 2001 and December 31, 2000
and for the three and six months ended June 30, 2001 and 2000 is summarized as
follows:

NOTE 3 -- 12 1/2% SENIOR NOTES

     As of June 30, 2001, the Company's outstanding balance under its 12 1/2%
Senior Notes was $75,172,000. On May 1, 2001, the Company completed a consent
solicitation with respect to the 12 1/2% Senior Notes and received consents from
holders of $39,279,000 of the then outstanding notes to extend the maturity date
from July 1, 2001 to July 1, 2003 and to make certain amendments to the note
covenants. Although the Company initially intended to accept consents from no
more than 50% of holders, the Company elected to accept additional consents, as
contemplated by the consent solicitation documents. The consenting holders
received a consent fee of 4% of the principal balance. Subsequently, during May
and June 2001, the Company had also repurchased $31,444,000 of the Senior Notes
from non-consenting holders.

     In June 2001, General William Lyon, Chairman and Chief Executive Officer of
the Company, and a trust for which his son William Harwell Lyon is a
beneficiary, purchased at par $30,000,000 of the 12 1/2% Senior Notes. William
Harwell Lyon is also an employee and a Director of the Company. Effective in
July 2001, William H. McFarland, another member of the Company's Board of
Directors, purchased at par $1,000,000 of the 12 1/2% Senior Notes. In parity
with holders consenting during the consent solicitation, these Directors
received a consent fee of 4% of the principal balance and consented to the
amendments effected by the Company's consent solicitation statement dated
February 28, 2001.

     The Company has repaid all of the remaining 12 1/2% Senior Notes which
matured on July 1, 2001 amounting to $5,893,000. After the transactions
described above, $70,279,000 of the 12 1/2% Senior Notes are outstanding with a
maturity date of July 1, 2003.

     In April and May 2000, the Company purchased $21,775,000 principal amount
of its outstanding Senior Notes at a cost of $21,125,000. The net gain resulting
from the purchase was $496,000 after giving effect to income taxes of $26,000
and amortization of related loan costs of $128,000. Such gain is reflected as an
extraordinary item in the Company's results of operations for the second quarter
ended June 30, 2000.

     The 12 1/2% Senior Notes are obligations of William Lyon Homes, a Delaware
corporation ("Delaware Lyon"), and are unconditionally guaranteed on a senior
basis by William Lyon Homes, Inc., a California corporation and a wholly-owned
subsidiary of Delaware Lyon. However, William Lyon Homes, Inc. has

granted liens on substantially all of its assets as security for its obligations
under certain revolving credit facilities and other loans. Because the William
Lyon Homes, Inc. guarantee is not secured, holders of the Senior Notes are
effectively junior to borrowings under the revolving credit facilities with
respect to such assets. Delaware Lyon and its consolidated subsidiaries are
referred to collectively herein as the "Company." Interest on the Senior Notes
is payable on January 1 and July 1 of each year.

     Supplemental consolidating financial information of the Company,
specifically including information for William Lyon Homes, Inc. is presented
below. Investments in subsidiaries are presented using the equity method of
accounting. Separate financial statements of William Lyon Homes, Inc. are not
provided, as the consolidating financial information contained herein provides a
more meaningful disclosure to allow investors to determine the nature of assets
held and the operations of the combined groups.

NOTE 4 -- GAIN FROM SALE OF OFFICE BUILDING

     In March 2000, the Company completed the sale of an office building where
its prior executive offices were located in Newport Beach, California which was
no longer needed after the consolidation of certain of the Company's operations.
The sales price was $2,120,000 which the Company received in cash at closing.
The net gain from the sale of approximately $1,747,000 is reflected in Other
income (expense), net on the Consolidated Statement of Income for the six months
ended June 30, 2000.

NOTE 5 -- RELATED PARTY TRANSACTIONS

     The Company and certain members of the Company's Board of Directors entered
into certain transactions with respect to the Company's 12 1/2% Senior Notes as
described in Note 3 of Notes to Consolidated Financial Statements.

     The Company purchased real estate projects for a total purchase price of
$869,000 during the six months ended June 30, 2000 from entities controlled by
William Lyon, Chairman of the Board of Directors and Chief Executive Officer of
the Company and William H. Lyon, the son of William Lyon and a director and
employee of the Company.

     On October 26, 2000, the Company's Board of Directors (with Messrs. William
Lyon and William H. Lyon abstaining) approved the purchase of 579 lots for a
total purchase price of $12,581,000 from an entity controlled by William Lyon
and William H. Lyon. The terms of the purchase agreement provided for an initial
option payment of $1,000,000 and a rolling option takedown of the lots. Phase
takedowns of approximately 20 lots each are anticipated to occur at two to three
month intervals for each of several product types through September 2004. In
addition, one-half of the net profits in excess of six percent from the
development are to be paid to the seller. During the three and six months ended
June 30, 2001, the Company purchased 64 and 104 lots, respectively, under this
agreement for a total purchase price of $1,374,000 and $1,975,000, respectively.
This land acquisition qualifies as an affiliate transaction under the Company's
$200,000,000 12 1/2% Senior Notes due July 1, 2001 Indenture dated as of June
29, 1994 ("Indenture"). Pursuant to the terms of the Indenture, the Company has
determined that the land acquisition is on terms that are no less favorable to
the Company than those that would have been obtained in a comparable transaction
by the Company with an unrelated person. The Company has delivered to the
Trustee under the Indenture a resolution of the Board of Directors of the
Company set forth in an Officers' Certificate certifying that the land
acquisition is on terms that are no less favorable to the Company than those
that would have been obtained in a comparable transaction by the Company with an
unrelated person and the land acquisition has been approved by a majority of the
disinterested members of the Board of Directors of the Company. Further, the
Company has delivered to the Trustee under the Indenture a determination of
value by a real estate appraisal firm which is of regional standing in the
region in which the subject property is located and is MAI certified.

     For the three and six months ended June 30, 2001, the Company incurred
on-site labor costs of $47,000 and $93,000, respectively for providing customer
service to real estate projects developed by entities controlled by William Lyon
and William H. Lyon, of which $34,000 was due to the Company at June 30, 2001.

     For the three and six months ended June 30, 2000, the Company earned
management fees of $172,000 and $280,000, respectively, and on-site labor cost
reimbursements of $80,000 and $276,000, respectively, for managing and selling
real estate owned by entities controlled by William Lyon and William H. Lyon.

     For the three and six months ended June 30, 2001, the Company incurred
charges of $183,000 and $365,000, respectively, related to rent on its corporate
office, from a trust of which William H. Lyon is the sole beneficiary.

(1) The Company ceased its operations in New Mexico in mid-2000.

     Homes in backlog are generally closed within three to six months. The
dollar amount of backlog of homes sold but not closed as of June 30, 2001 was
$330.1 million, as compared to $273.6 million as of June 30, 2000 and $260.1
million as of March 31, 2001. The cancellation rate of buyers who contracted to
buy a home but did not close escrow at the Company's projects was approximately
20% during 2000 and 19% during the first six months of 2001.

     The number of homes sold for the quarter ended June 30, 2001 increased 30%
to 767 units from 588 for the second quarter of 2000. For the second quarter of
2001, the number of homes sold increased 4 percent to 767 from 741 units in the
first quarter of 2001. The number of homes closed in the second quarter of 2001
increased 2 percent to 601 from 587 in the second quarter of 2000. The backlog
of homes sold as of June 30, 2001 was 1,074, up 23 percent from 871 units a year
earlier, and up 18 percent from 908 units at March 31, 2001.

     In general, housing demand is adversely affected by increases in interest
rates and housing prices. Interest rates, the length of time that assets remain
in inventory, and the proportion of inventory that is financed affect the
Company's interest cost. If the Company is unable to raise sales prices
sufficiently to compensate for higher costs or if mortgage interest rates
increase significantly, affecting prospective buyers' ability to adequately
finance home purchases, the Company's sales, gross margins and operating results
may be adversely impacted.

  COMPARISON OF THREE MONTHS ENDED JUNE 30, 2001 TO THREE MONTHS ENDED JUNE 30,
2000

     Operating revenue for the three months ended June 30, 2001 was $106.7
million, an increase of $10.0 million (10.3%) from operating revenue of $96.7
million for the three months ended June 30, 2000. Revenue from sales of homes
increased $11.1 million (11.8%) to $105.2 million in the 2001 period from $94.1
million in the 2000 period. This increase was primarily due to an increase in
the number of wholly-owned units closed to 465 in the 2001 period from 387 in
the 2000 period, offset by decrease in the average sales prices of wholly-owned
units due to product mix to $226,300 in the 2001 period from $243,300 in the
2000 period. Management fee income decreased by $0.9 million to $1.4 million in
the 2001 period from $2.3 million in the 2000 period primarily due to a decrease
in the number of unconsolidated joint venture units closed to 136 in the 2001
period from 200 in the 2000 period.

     Total operating income decreased from $12.8 million in the 2000 period to
$9.2 million in the 2001 period. The excess of revenue from sales of homes over
the related cost of sales was unchanged at $17.7 million in both periods,
despite a decline in gross margins of 2.0 percent to 16.8 percent in the 2001
period from 18.8 percent in the 2000 period. This was primarily due to an
increase in the number of wholly-owned units closed to 465 units in the 2001
period from 387 units in the 2000 period, offset by a decrease in the average
sales prices of wholly-owned units due to product mix to $226,300 in the 2001
period from $243,600 in the 2000 period. The Company's revenues and total
operating income are affected by the proportion of units sold by the Company and
those sold by unconsolidated joint ventures. While the average sales price of
homes sold by joint ventures has been higher than the average sales price of
wholly-owned units, the Company generally receives, after priority returns and
capital distributions, approximately 50% of the profits and losses and cash
flows from joint ventures. Sales and marketing expenses increased by $1.3
million to $4.7 million in the 2001 period from $3.4 million in the 2000 period
primarily due to the increased sales volume. General and administrative expenses
decreased by $0.8 million to $8.1 million in the 2001 period from $8.9 million
in the 2000 period, primarily as a result of a reduction in outside consultants'
expenses and legal expense. Equity in income of unconsolidated joint ventures
amounting to $3.5 million was recognized in the 2001 period, down from $5.4
million in the comparable period for 2000 primarily as a result of a decrease in
the number of units closed to 136 in the 2001 period from 200 in the 2000
period.

     Total interest incurred decreased $0.5 million (7.9%) from $6.3 million in
the 2000 period to $5.8 million in the 2001 period primarily as a result of (1)
the replacement of the Company's prior $100.0 million working capital facility
with revolving credit facilities (see description below) with lower effective
borrowing costs, (2) reduction of the outstanding principal balance of 12 1/2%
Senior Notes through the secured working capital facilities with lower effective
borrowing costs and (3) decreases in interest rates. All interest incurred was
capitalized in the 2001 period while $1.9 million of interest incurred was
expensed in the 2000 period as a result of a decrease in total interest incurred
and an increase in interest capitalized to real estate inventories.

     Other income (expense), net increased to $1.6 million in the 2001 period
from $0.6 million in the 2000 period primarily as a result of increased income
from the Company's design center and mortgage company operations.

COMPARISON OF SIX MONTHS ENDED JUNE 30, 2001 TO SIX MONTHS ENDED JUNE 30, 2000

     Operating revenue for the six months ended June 30, 2001 was $180.8
million, an increase of $17.1 million (10.4%) from operating revenue of $163.7
million for the six months ended June 30, 2000. Revenue from sales of homes
increased $11.8 million (7.4%) to $170.6 million in the 2001 period from $158.8
million in the 2000 period. This increase was primarily due to an increase in
the number of

                                        24
   25

wholly-owned units closed to 751 in the 2001 period from 706 in the 2000 period,
and an increase in the average sales prices of wholly-owned units to $227,200 in
the 2001 period from $224,900 in the 2000 period. Revenue from sales of lots,
land and other increased $6.1 million to $7.1 million in the 2001 period from
$1.0 million in the 2000 period as a result of the sale of two commercial sites
in Southern California and Arizona in the 2001 period. Management fee income
decreased by $0.9 million to $3.1 million in the 2001 period from $4.0 million
in the 2000 period primarily due to a decrease in the number of unconsolidated
joint venture units closed to 250 in the 2001 period from 400 in the 2000
period.

     Total operating income decreased from $20.4 million in the 2000 period to
$15.4 million in the 2001 period. The excess of revenue from sales of homes over
the related cost of sales decreased by $1.7 million to $28.1 million in the 2001
period from $29.8 million in the 2000 period, resulting in a decline in gross
margins of 2.4 percent to 16.4 percent in the 2001 period from 18.8 percent in
the 2000 period. This decrease was primarily due to a change in the mix of
product, an increase in the number of wholly-owned units closed to 751 units in
the 2001 period from 706 units in the 2000 period, offset by an increase in the
average sales prices of wholly-owned units to $227,200 in the 2001 period from
$224,900 in the 2000 period. The Company's revenues and total operating income
are affected by the proportion of units sold by the Company and those sold by
unconsolidated joint ventures. While the average sales price of homes sold by
joint ventures has been higher than the average sales price of wholly-owned
units, the Company generally receives, after priority returns and capital
distributions, approximately 50% of the profits and losses and cash flows from
joint ventures. Sales and marketing expenses increased by $1.4 million to $8.4
million in the 2001 period from $7.0 million in the 2000 period primarily due to
the increased sales volume. General and administrative expenses increased by
$0.5 million to $16.9 million in the 2001 period from $16.4 million in the 2000
period, primarily as a result of increases in salaries and benefits related to
the Company's increased operations, offset by a reduction in outside
consultants' expense and legal expense. Equity in income of unconsolidated joint
ventures amounting to $7.3 million was recognized in the 2001 period, down from
$10.5 million in the comparable period for 2000 primarily as a result of a
decrease in the number of units closed to 250 in the 2001 period from 400 in the
2000 period.

     Total interest incurred decreased $1.2 million (9.7%) from $12.4 million in
the 2000 period to $11.2 million in the 2001 period primarily as a result of (1)
the replacement of the Company's prior $100.0 million working capital facility
with revolving credit facilities (see description below) with lower effective
borrowing costs, (2) reduction of the outstanding principal balance of 12 1/2%
Senior Notes through the secured working capital facilities with lower effective
borrowing costs and (3) decreases in interest rates. Net interest expense
decreased to $0.2 million in the 2001 period from $3.5 million in the 2000
period as a result of a decrease in total interest incurred and an increase in
interest capitalized to real estate inventories.

     Other income (expense), net decreased to $2.3 million in the 2001 period
from $2.6 million in the 2000 period primarily as a result of a gain from the
sale of an office building in the 2000 period, offset by increased income from
the Company's design center and mortgage company operations.

FINANCIAL CONDITION AND LIQUIDITY

     The Company provides for its ongoing cash requirements principally from
internally generated funds from the sales of real estate and from outside
borrowings and, beginning in the fourth quarter of 1997, by joint venture
financing from newly formed joint ventures with venture partners that provide a
substantial portion of the capital required for certain projects. The Company
currently maintains the following major credit facilities: 12 1/2% Senior Notes
(the "Senior Notes"), secured revolving credit facilities ("Revolving Credit
Facilities") and an unsecured revolving line of credit with a commercial bank
("Unsecured Revolving Line"). The Company also finances certain projects with
construction loans secured by real estate inventories and finances certain land
acquisitions with seller-provided financing.

     The ability of the Company to meet its obligations on its indebtedness will
depend to a large degree on its future performance which in turn will be
subject, in part, to factors beyond its control, such as prevailing economic
conditions, mortgage and other interest rates, weather, the occurrence of events
such as landslides, soil subsidence and earthquakes that are uninsurable, not
economically insurable or not subject to effective

                                        25
   26

indemnification agreements, availability of labor and homebuilding materials,
changes in governmental laws and regulations, and the availability and cost of
land for future development.

  SENIOR NOTES

     As of June 30, 2001, the Company's outstanding balance under its 12 1/2%
Senior Notes was $75,172,000. On May 1, 2001, the Company completed a consent
solicitation with respect to the 12 1/2% Senior Notes and received consents from
holders of $39,279,000 of the then outstanding notes to extend the maturity date
from July 1, 2001 to July 1, 2003 and to make certain amendments to the note
covenants. Although the Company initially intended to accept consents from no
more than 50% of holders, the Company elected to accept additional consents, as
contemplated by the consent solicitation documents. The consenting holders
received a consent fee of 4% of the principal balance. Subsequently, during May
and June 2001, the Company had also repurchased $31,444,000 of the Senior Notes
from non-consenting holders.

     In June 2001, General William Lyon, Chairman and Chief Executive Officer of
the Company, and a trust for which his son William Harwell Lyon is a
beneficiary, purchased at par $30,000,000 of the 12 1/2% Senior Notes. William
Harwell Lyon is also an employee and a Director of the Company. Effective in
July 2001, William H. McFarland, another member of the Company's Board of
Directors, purchased at par $1,000,000 of the 12 1/2% Senior Notes. In parity
with holders consenting during the consent solicitation, these Directors
received a consent fee of 4% of the principal balance and consented to the
amendments effected by the Company's consent solicitation statement dated
February 28, 2001.

     The Company has repaid all of the remaining 12 1/2% Senior Notes which
matured on July 1, 2001 amounting to $5,893,000. After the transactions
described above, $70,279,000 of the 12 1/2% Senior Notes are outstanding with a
maturity date of July 1, 2003.

     In April and May 2000, the Company purchased $21,775,000 principal amount
of its outstanding Senior Notes at a cost of $21,125,000. The net gain resulting
from the purchase was $496,000 after giving effect to income taxes of $26,000
and amortization of related loan costs of $128,000. Such gain is reflected as an
extraordinary item in the Company's results of operations for the second quarter
ended June 30, 2000.

     The 12 1/2% Senior Notes (the "Senior Notes") are obligations of William
Lyon Homes, a Delaware corporation ("Delaware Lyon"), and are unconditionally
guaranteed on a senior basis by William Lyon Homes, Inc., a California
corporation and a wholly-owned subsidiary of Delaware Lyon. However, William
Lyon Homes, Inc. has granted liens on substantially all of its assets as
security for its obligations under the Revolving Credit Facilities and other
loans. Because the William Lyon Homes, Inc. guarantee is not secured, holders of
the Senior Notes are effectively junior to borrowings under the Revolving Credit
Facilities with respect to such assets. Interest on the Senior Notes is payable
on January 1 and July 1 of each year.

     The Senior Notes are senior obligations of Delaware Lyon and rank pari
passu in right of payment to all existing and future unsecured indebtedness of
Delaware Lyon, and senior in right of payment to all future indebtedness of the
Company which by its terms is subordinated to the Senior Notes.

     Delaware Lyon is required to offer to repurchase certain Senior Notes at a
price equal to 100% of the principal amount plus any accrued and unpaid interest
to the date of repurchase if Delaware Lyon's Consolidated Tangible Net Worth is
less than $60.0 million on the last day of each of any two consecutive fiscal
quarters, as well as from the proceeds of certain asset sales.

     Upon certain changes of control as described in the Indenture, Delaware
Lyon must offer to repurchase Senior Notes at a price equal to 101% of the
principal amount plus accrued and unpaid interest, if any, to the date of
repurchase.

     The Indenture governing the Senior Notes restricts Delaware Lyon and
certain of its subsidiaries with respect to, among other things: (i) the payment
of dividends on and redemptions of capital stock, (ii) the incurrence of
indebtedness or the issuance of preferred stock, (iii) the creation of certain
liens, (iv) consolidation or mergers with or transfers of all or substantially
all of its assets and (v) transactions with affiliates. These restrictions are
subject to a number of important qualifications and exceptions.

  REVOLVING CREDIT FACILITIES

     The Revolving Credit Facilities have an aggregate maximum loan commitment
of $180.0 million and mature at various dates beginning in 2002 through
September 2004. The collateral for the loans provided by the Revolving Credit
Facilities includes substantially all real estate of the Company (excluding
assets which are pledged as collateral for construction notes payable described
below and excluding assets of partnerships and limited liability companies).
Although the aggregate maximum loan commitment for these loans is $180.0
million, the credit facilities have limitations on the amounts which can be
borrowed at any time based on assets which are included in the credit facilities
and the specified borrowings permitted under borrowing base calculations. The
undrawn availability at June 30, 2001 was $39.7 million and the principal
outstanding under the Revolving Credit Facilities at June 30, 2001 was $120.4
million. Pursuant to the terms of the Revolving Credit Facilities, outstanding
advances bear interest at various rates which approximate the prime rate. The
Revolving Credit Facilities include financial covenants which may limit the
amount which may be borrowed thereunder.

  UNSECURED REVOLVING LINE

     Effective March 8, 2001 the Company obtained an unsecured revolving line of
credit with a commercial bank in the amount of $10.0 million. The Unsecured
Revolving Line bears interest at prime plus 1% and matures on March 12, 2002.
The Unsecured Revolving Line includes financial covenants which may limit the
amount which may be borrowed thereunder. As of June 30, 2001 $8.3 million was
outstanding under the Unsecured Revolving Line.

  CONSTRUCTION NOTES PAYABLE

     At June 30, 2001, the Company had construction notes payable amounting to
$11.4 million related to various real estate projects. The notes are due as
units close or at various dates on or before December 31, 2002 and bear interest
at rates of prime plus 0.25% to prime plus 0.50%.

  SELLER FINANCING

     Another source of financing available to the Company is seller-provided
financing for land acquired by the Company. At June 30, 2001, the Company had no
notes payable outstanding related to land acquisitions for which seller
financing was provided.

  REVOLVING MORTGAGE WAREHOUSE CREDIT FACILITY

     The Company has a $15.0 million revolving mortgage warehouse credit
facility with a bank to fund its mortgage origination operations. Mortgage loans
are generally held for a short period of time and are typically sold to
investors within 7 to 15 days following funding. Borrowings are secured by the
related mortgage loans held for sale. At June 30, 2001 the outstanding balance
was $3.2 million. The facility, which has a current maturity date of May 31,
2002, also contains a financial covenant requiring the Company to maintain cash
and/or marketable securities on the books of account of its subsidiary, Duxford
Financial, Inc., a California corporation ("Duxford") in an amount equal to no
less than $1.0 million and a financial covenant requiring the Company to
maintain total assets net of total liabilities and net of amounts receivable
from the Company and/or affiliates on the books of account of Duxford in an
amount equal to no less than $1.0 million.

  JOINT VENTURE FINANCING

     As of June 30, 2001, the Company and certain of its subsidiaries are
general partners or members in joint ventures involved in the development and
sale of residential projects. Such joint ventures are 50% or less owned and,
accordingly, the financial statements of such joint ventures are not
consolidated with the Company's financial statements. The Company's investments
in unconsolidated joint ventures are accounted for using the equity method. See
Note 2 of "Notes to Consolidated Financial Statements" for condensed combined
financial information for these joint ventures. Based upon current estimates,
substantially all future

                                        27
   28

development and construction costs will be funded by the Company's venture
partners or from the proceeds of construction financing obtained by the joint
ventures.

     As of June 30, 2001, the Company's investment in and advances to such joint
ventures was approximately $50.5 million and the Company's venture partners'
investment in such joint ventures was approximately $140.9 million. In addition,
certain joint ventures have obtained financing from land sellers or construction
lenders which amounted to approximately $66.3 million at June 30, 2001.

  ASSESSMENT DISTRICT BONDS

     In some jurisdictions in which the Company develops and constructs
property, assessment district bonds are issued by municipalities to finance
major infrastructure improvements and fees. Such financing has been an important
part of financing master-planned communities due to the long-term nature of the
financing, favorable interest rates when compared to the Company's other sources
of funds and the fact that the bonds are sold, administered and collected by the
relevant government entity. As a landowner benefited by the improvements, the
Company is responsible for the assessments on its land. When the Company's homes
or other properties are sold, the assessments are either prepaid or the buyers
assume the responsibility for the related assessments.

  CASH FLOWS -- COMPARISON OF SIX MONTHS ENDED JUNE 30, 2001 TO SIX MONTHS ENDED
  JUNE 30, 2000

     Net cash used in operating activities was $44.5 million in the 2001 period
and net cash provided by operating activities was $2.8 million in the 2000
period. The change was primarily as a result of an increase in real estate
inventories in the 2001 period.

     Net cash provided by investing activities was $8.2 million in the 2001
period and net cash used in investing activities was $3.4 million in the 2000
period. The change was primarily as a result of increased net cash received from
unconsolidated joint ventures in the 2001 period.

     Net cash provided by financing activities increased from $5.8 million in
the 2000 period to $51.7 million in the 2001 period primarily as a result of
increased net borrowings on notes payable.

NET OPERATING LOSS CARRYFORWARDS

     At December 31, 2000, the Company had net operating loss carryforwards for
Federal tax purposes of approximately $56.0 million, of which $1.3 million
expires in 2008, $10.5 million expires in 2009, $14.1 million expires in 2010,
$13.7 million expires in 2011, $16.4 million expires in 2012 and $28,000 expires
in 2018. In addition, unused recognized built-in losses in the amount of $23.9
million are available to offset future income and expire between 2009 and 2011.
The Company's ability to utilize the foregoing tax benefits will depend upon the
amount of its otherwise taxable income and may be limited in the event of an
"ownership change" under federal tax laws and regulations. In addition, the
Company's federal income tax returns for 1997, 1998 and 1999 are currently under
examination by the Internal Revenue Service and there can be no assurance that
the Service will not challenge the amount of tax benefits calculated by the
Company.

NEW YORK STOCK EXCHANGE LISTING

     The Company has previously announced that it had received notification from
the New York Stock Exchange on July 28, 1999 that the Securities and Exchange
Commission has approved amendments to the NYSE's continued listing standards.
Under these new standards, the Company would be considered "below criteria" if
it has:

     - Total market capitalization of less than $50 million;

     - Total stockholders' equity of less than $50 million;

     - Average market capitalization of less than $15 million over a consecutive
       30-day trading period; or

     - Average closing price of less than $1.00 over a consecutive 30
       trading-day period.

     The NYSE notified the Company that it was below these new criteria on the
date of the notification. The NYSE further informed the Company that failure to
raise its stock price above $1.00 per share within six months would result in
immediate suspension of trading and application to the SEC for delisting. In
addition, the Company would have 45 days from the date of the NYSE's
notification to present a business plan to the NYSE that would demonstrate
compliance with all aspects of the other two criteria within 12 months of the
date of the NYSE's notification. The Company submitted a business plan to the
NYSE within the 45 day period. On September 30, 1999, the NYSE notified the
Company that it had accepted the Company's business plan and would continue the
listing of the Company at that time. The NYSE notification further stated that
the NYSE would continue to monitor the Company quarterly during the twelve
months from the date of the notification. If the Company failed to achieve the
quarterly milestones or if at the completion of the 12 months it was not in
compliance with the new continued listing criteria, the Company would be
suspended from trading on the NYSE and application would be made to the SEC for
delisting.

     On August 29, 2000 the Company announced that it had received a letter from
the NYSE dated as of August 14, 2000 notifying the Company that the plan period
under the NYSE's Continued Listing Program for the Company was completed as of
August 5, 2000. According to the NYSE letter, the Company completed the plan
period and is now considered a "company in good standing" by achieving both
market capitalization and shareholders' equity in excess of $50 million. As a
result of the Company's good standing, the Company has formally been removed
from the NYSE's "Watch List". However, the Company is subject to a 12-month
follow-up period within which the Company will be reviewed to ensure that the
Company does not once again fall below any of the NYSE's continued listing
standards. Although no quarterly updates are required during the follow-up
period, the Company is still obligated to be proactive in its discussions with
the NYSE, especially involving events that might effect triggering any of the
continued listing requirements. As of and through June 30, 2001, the Company was
in compliance with all NYSE listing criteria.

INFLATION

     The Company's revenues and profitability may be affected by increased
inflation rates and other general economic conditions. In periods of high
inflation, demand for the Company's homes may be reduced by increases in
mortgage interest rates. Further, the Company's profits will be affected by its
ability to recover through higher sales prices increases in the costs of land,
construction, labor and administrative expenses. The Company's ability to raise
prices at such times will depend upon demand and other competitive factors.

FORWARD LOOKING STATEMENTS

     Investors are cautioned that certain statements contained in this Quarterly
Report on Form 10-Q, as well as some statements by the Company in periodic press
releases and some oral statements by Company officials to securities analysts
and stockholders during presentations about the Company are "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995 (the "Act"). Statements which are predictive in nature, which depend
upon or refer to future events or conditions, or which include words such as
"expects", "anticipates", "intends", "plans", "believes", "estimates", "hopes",
and similar expressions constitute forward-looking statements. In addition, any
statements concerning future

                                        34
   35

financial performance (including future revenues, earnings or growth rates),
ongoing business strategies or prospects, and possible future Company actions,
which may be provided by management are also forward-looking statements as
defined in the Act. Forward-looking statements are based upon expectations and
projections about future events and are subject to assumptions, risks and
uncertainties about, among other things, the Company, economic and market
factors and the homebuilding industry.

     Actual events and results may differ materially from those expressed or
forecasted in the forward-looking statements due to a number of factors. The
principal factors that could cause the Company's actual performance and future
events and actions to differ materially from such forward-looking statements
include, but are not limited to, changes in general economic conditions either
nationally or in regions in which the Company operates, whether an ownership
change occurs which results in the limitation of the Company's ability to
utilize the tax benefits associated with its net operating loss carryforward,
changes in home mortgage interest rates, changes in prices of homebuilding
materials, labor shortages, adverse weather conditions, the occurrence of events
such as landslides, soil subsidence and earthquakes that are uninsurable, not
economically insurable or not subject to effective indemnification agreements,
changes in governmental laws and regulations, whether the Company is able to
refinance the outstanding balances of Senior Notes at their maturity, the timing
of receipt of regulatory approvals and the opening of projects and the
availability and cost of land for future growth.

RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the Financial Accounting Standards Board issued Statement No.
133, Accounting for Derivative Instruments and Hedging Activities, and its
amendments Statements No. 137 and 138, in June 1999 and June 2000, respectively,
(collectively, the "Statements"). The Statements are effective for fiscal years
beginning after June 15, 2000 (January 1, 2001 for the Company). The Company
adopted the new Statements on January 1, 2001; however, because the Company
currently has no derivatives, there is currently no impact on the financial
position or the results of operations of the Company.
