Notes to the Unaudited Consolidated Financial Statements

(1)     DESCRIPTION OF BUSINESS

        NAB Asset Corporation, a Texas Corporation (the "Company" or "NAB") is
primarily engaged in the residential lending business. As discussed below the
Company disposed of its retail automotive sales business in June, 1997. Prior to
June 5, 1996 the Company's business consisted of the acquisition, ownership,
management and disposition of loans and real estate for its own account and the
account of others.

        The Company was organized on March 31, 1991, by National Asset Bank (a
bank in liquidation) (the "Bank") as a wholly-owned subsidiary of the Bank for
the purpose of acquiring substantially all of the assets of the Bank through a
series of transactions and agreements intended to effect the final liquidation
of the Bank. The Company acquired substantially all of the assets of the Bank in
consideration of the issuance by the Company of shares of its common stock, $.01
par value (the "Common Stock"), and the assumption of all the Bank's
liabilities. Immediately following such acquisition, the Bank distributed the
shares of Common Stock received to the holders of the Bank's common stock, (the
"Bank Common Stock"), on the basis of one share of Common Stock for each ten
shares of the Bank Common Stock held of record as of the close of business on
July 17, 1991. Because the Company was formed for the purpose of effecting the
acquisition of substantially all of the Bank's assets, the Company had only
limited operating activities prior to such acquisition.

        On June 5, 1996, pursuant to the Plan and Agreement of Merger, CPS
Investing Corp. ("CPS Sub"), a wholly owned subsidiary of Consumer Portfolio
Services, Inc. ("CPS"), was merged with and into NAB (the "Merger"). Under the
terms of the Plan and Agreement of Merger and in exchange for all of the
outstanding shares of NAB $.01 par value common stock, the shareholders of NAB
received on a pro rata basis (i) an aggregate cash distribution of $15.3 million
($3.64 per share), (ii) an undivided interest in a liquidating trust
("Liquidating Trust"), and (iii) 62% of the outstanding shares of common stock,
$.10 par value (the "New Common Stock") of the new combined company which had a
net asset value of $7.5 million as of the merger date. The Liquidating Trust was
established for the benefit of converting the trust assets to cash for the NAB
shareholders. On June 5, 1996 in connection with the Merger, NAB contributed
approximately $3.0 million in cash and all of the remaining non-cash assets of
NAB with a net book value of $3.7 million to the Liquidating Trust. No gain or
loss was recognized by NAB in connection with the merger. In exchange for a $4
million contribution to NAB, CPS received 38% or 1,934,706 shares of the New
Common Stock of NAB.

(2)     BASIS OF FINANCIAL STATEMENT PRESENTATION

        The consolidated balance sheet of the Company as of June 30, 1998, the
related consolidated statements of operations for the three and six month
periods ended June 30, 1998 and 1997, and the related statements of cash flows
for the six month periods ended June 30, 1998


                                       5

and 1997 are unaudited. These statements reflect, in the opinion of management,
all material adjustments consisting only of normal recurring accruals necessary
for a fair presentation of the consolidated balance sheet of the Company as of
June 30, 1998, and results of consolidated operations for the three and six
months ended June 30, 1998 and 1997 and the consolidated cash flows for the six
month period ended June 30, 1998 and 1997. The results of consolidated
operations for the unaudited periods are not necessarily indicative of the
results of consolidated operations to be expected for the entire year of 1998.

        The accompanying unaudited consolidated financial statements have been
prepared in accordance with the instructions to Securities and Exchange
Commission ("SEC") Form 10-Q and therefore do not include all information and
footnotes normally included in consolidated financial statements prepared in
conformity with generally accepted accounting principles. Accordingly, these
unaudited consolidated financial statements should be read in conjunction with
the audited consolidated financial statements and notes thereto included in the
Company's annual report on SEC form 10-K for the year ended December 31, 1997.

        On January 1, 1998 the Company adopted Statement of Financial Accounting
Standards No. 130 (SFAS No. 130), "Reporting Comprehensive Income". SFAS 130
defines comprehensive income as the total of all components of comprehensive
income, including net income and other comprehensive income. The term "other
comprehensive income" refers to revenues, expenses, gains and losses that under
generally accepted accounting principles are included in comprehensive income
but excluded from net income. Other comprehensive income items are classified
separately into foreign currency items, minimum pension liability adjustments,
and unrealized gains and losses on certain investments in debt and equity
securities. All components of comprehensive income shall be reported in the
financial statements in the period in which they are recognized; however, if
there are no items of other comprehensive income in any period presented, then
comprehensive income is not required to be reported in that period. The adoption
of SFAS No. 130 did not have any material impact on the Company's financial
statements. During the six months ended June 30, 1998 and 1997, there were no
items of other comprehensive income recognized.

        In February 1998, the FASB issued Statement of Financial Accounting
Standards No. 132 (SFAS No. 132), "Employers Disclosures about Pension and Other
Postretirement Benefits." SFAS No. 132 amends the disclosure requirements of
SFAS No. 87, "Employers' Accounting for Settlements and Curtailments of Defined
Benefit Pension Plans and for Termination Benefits," and SFAS No. 106,
"Employer's Accounting for Retirement Benefits Other than Pensions". SFAS No.
132 standardizes the disclosure requirements of SFAS No. 87 and 106 to the
extent practicable and recommends a parallel format for presenting information
about pensions and other retirement benefits. SFAS No. 132 is effective for
fiscal years beginning after December 15, 1997. SFAS No. 132 will result in
disclosure changes only.

        In June 1998, the FASB issued Statement of Financial Accounting
Standards No. 133 "Accounting for Derivative Instruments and Hedging
Activities." SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative 


                                       6


<PAGE>   7
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. If certain conditions are
met, a derivative may be specifically designed as (a) a hedge of the exposure to
changes in the fair value of a recognized asset or liability or an unrecognized
firm commitment, (b) a hedge of the exposure to variable cash flows of a
forecasted transaction, or (c) a hedge of the foreign currency exposure of a net
investment in a foreign operation, an unrecognized firm commitment, an
available-for-sale security, or a foreign-currency-denominated forecasted
transaction. Under SFAS No. 133, an entity that elects to apply hedge accounting
is required to establish at the inception of the hedge the method it will use
for assessing the effectiveness of the hedging derivative and the measurement
approach for determining the ineffective aspect of the hedge. Those methods must
be consistent with the entity's approach to managing risk.

        SFSA No. 133 supercedes FASB Statements No. 80 "Accounting for Futures
Contracts", No. 105 "Disclosure of Information about Financial Instruments with
Off-Balance Sheet Risk and Financial Instruments with Concentrations of Credit
Risk," and No. 119, "Disclosure about Derivative Financial Instruments and Fair
Value of Financial Instruments". It amends FASB Statement No. 107 "Disclosures
about the Fair Value of Financial Instruments" to include in Statement 107 the
disclosure provisions about concentration of credit risk from Statement 105.
This Statement also nullifies or modifies the consensus reached in a number of
issues addressed by the Emerging Issues Task Force. This Statement is effective
for all fiscal quarters of fiscal years beginning after June 15, 1999.
Management is in the process of assessing the future impact of the
implementation of SFAS No. 133.

(3)     ACQUISITIONS AND DISPOSITIONS

        On December 30, 1997 the Company, through a newly formed 86% owned
subsidiary, Construction Portfolio Funding, Inc. ("CPFI") acquired approximately
$53,000,000 in single family construction loans from a bank. A premium of
$250,000 was paid in addition to the principal balances acquired.

        Additionally on December 30, 1997, CPFI acquired $2,000,000 in
residential lot loans from NAFCO, Inc., ("NAFCO") an 84% owned subsidiary of NAB
that were acquired from the bank in November, 1997.

        In March 1997, NAB entered into a definitive agreement to sell its
interest in CARS and on June 27, 1997 completed the transaction. The acquirer
was a newly formed company owned by Charles E. Bradley, Sr., the chief executive
officer and chairman of the board of NAB and Charles E. Bradley, Jr., a director
of NAB. The purchase price consisted of a $200,000 cash payment and a note for
$1,300,000. The note bears interest at 9% payable quarterly and is included in
Commercial loans on the Consolidated Balance Sheets.

        As a result of NAB's decision to divest its retail automotive sales
operations, all related operating activity has been reported as discontinued
operations for financial reporting purposes.

        Revenue and expenses for the discontinued automotive sales operation
consisted primarily of sales and cost of sales, respectively.

(4)     RESIDUAL INTEREST IN SECURITIZATION OF MORTGAGE LOANS

        The Company records net gains on securitization of loans representing
the excess of the cash received and assets retained by the Company over the
relative fair value of the loans sold, less transaction costs. Various
assumptions are used in the calculation of the gain on the sale of the loans and
the valuation of the residual interest in the securitization of mortgage loans.

        The residual interests in the securitization of loans represent the
present value of the difference between the contractual interest rates on the
loans and the rate paid to the buyer or bondholder using those assumptions. The
residual interest is accounted for as a trading security and as such is recorded
at its estimated fair value. The Company is not aware of an active market for
the purchase or sale of the residual interests. Accordingly, the Company
determines the estimated fair value of the residual interests by discounting the
expected cash flows released from the trust (the cash out method) using a
discount rate which the Company believes is commensurate with the risks
involved.

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

        NAB is a financial services company engaged in residential mortgage
banking, residential construction lending and commercial finance. The
residential mortgage banking business, acquired in July 1996, originates,
acquires and sells prime and sub-prime mortgage loans. The residential
construction lending business, begun in December, 1997, originates and holds for
investment single family residential construction loans to homebuilders and to a
lesser extent lots, model homes, and acquisition and development projects for
those homebuilders. The commercial finance operations, begun in January, 1997,
provides financing to operators of rent-to-own or rental purchase retailers. On
June 27, 1997 the Company sold its interest in its retail automobile sales
business.

THREE MONTHS ENDED JUNE 30, 1998 COMPARED TO THREE MONTHS ENDED JUNE 30, 1997

        RESIDENTIAL MORTGAGE BANKING

        Revenues for the three months ended June 30, 1998 primarily consisted of
$4,778,000 in gains on sale of loans, $2,077,000 in fee income and $2,072,000 in
interest income. The $6,641,000 increase in revenues from $2,551,000 for the
three months ended June 30, 1997 primarily related to the additional revenues
generated by the acquisition of the assets and business of Pacific American
Mortgage Company (PAMCO) in August, 1997 and increased levels of loan
originations. The increase in revenues was primarily comprised of a $2,857,000
increase in gains on sale of loans, a $1,877,000 increase in fee income and a
$1,642,000 increase in interest income.

        The increased gain on sale of loans was due primarily to the sale of
$211.5 million in loans sold for the three months ended June 30, 1998 compared
to $43.7 million for the three months ended June 30, 1997. The increase in fee
income was primarily due to the increase in loan production to $235.8 million
for the three months ended June 30, 1998 compared to $46.4 million for the three
months ended June 30, 1997. The acquisition of PAMCO accounted for $149 million
of the increase in loan production and $139.3 million of the increase in loan
sales for the quarter ended June 30, 1998.

        Operating expenses for the three months ended June 30, 1998 primarily
consisted of $1,831,000 in interest expense, $4,603,000 in compensation and
benefit expense, $349,000 in intercompany tax expense, and $1,731,000 in general
and administrative expense. Operating expenses increased by $6,460,000 from
$2,054,000 for the prior period to $8,515,000 for the three months ended June
30, 1998. This increase consisted of $1,464,000 in interest expense, $3,473,000
in compensation and benefit expense, $303,000 in intercompany tax expense and
$1,221,000 in general and administrative expense. In general, expenses increased
due to the PAMCO acquisition, which accounted for the majority of the increase
in interest expense related to the additional warehouse line necessary to fund
the additional production. Compensation and benefits and general and
administrative expenses also increased mainly due to the addition of PAMCO.

        RESIDENTIAL CONSTRUCTION LENDING

        Revenues for the three months ended June 30, 1998 consisted of interest
income of $1,390,000 and fee income of $356,000.

$1,185,000 of interest expense, $167,000 of compensation and benefit expense,
$77,000 of bad debt expense and $201,000 of general and administrative expense.

        New loan commitments for residential construction for the three months
ended June 30, 1998 totaled $1,000,000.

        COMMERCIAL LENDING

        Revenues for the three months ended June 30, 1998 primarily consisted of
interest income of $291,000. The $129,000 increase in revenues from the three
months ended June 30, 1997 relates to the increase in loans receivable.

        Operating expenses for the three months ended June 30, 1998 consisted of
$50,000 in compensation and benefit expense, $47,000 in bad debt expense,
$10,000 in interest expense and $107,000 in general and administrative expense.
Operating expenses from the three months ended June 30, 1998 decreased $8,000
from the three months ended June 30, 1997.

        New loan commitments approved for the three months ended June 30, 1998
totaled $2,950,000 compared to $0 for the three months ended June 30, 1997.

        CORPORATE AND INTERCOMPANY ELIMINATIONS

        Corporate expenses for the three months ended June 30, 1998 increased
$241,000 from the three months ended June 30, 1997 primarily as a result of
increased compensation expense.

        In April 1998, the Board of Directors authorized the Company to make
payments to officers and Directors in lieu of stock options that were originally
granted under stock option plans that were never presented to shareholders for
approval. As a result, the Company recorded a charge of $132,000 which is
recorded in compensation expense for the three months ended June 30, 1998, and
is obligated to pay certain officers of the Company an additional $232,000 over
the period to January, 2000, contingent on continued employment. The Company
will record compensation expense as these amounts become due.

        CORPORATE AND INTERCOMPANY ELIMINATIONS

        Corporate expenses for the six months ended June 30, 1998 increased
$629,000 from the six months ended June 30, 1997 primarily as a result of the

repayments under the Company's residential warehouse line of credit. Of the

        In order to maintain its net operating loss carryforwards the Company is
limited under Section 382 of the Internal Revenue Code of 1986 as to issuance of
new common shares in order to raise additional capital. The Company must rely on
additional borrowings to grow its operations. NAB has relied on Stanwich
Financial Services Corp. (SFSC), a company that is 85% owned by Charles E.
Bradley, Sr. and Charles E. Bradley, Jr., directors of the Company, and CPS to
provide funds to support the additional growth of the Company. Management
believes that the Company can obtain extensions on its notes payable to
affiliates as necessary to support its ongoing operations

        SIGNIFICANT EVENTS

        Incentive Plan Restructure

        In 1997, the Company entered into agreements with the executives of MPS
that granted options to the executives, exercisable only if certain conditions
are satisfied, to acquire up to 20% of the authorized common shares of MPS. The
number of shares to be issued pursuant to the agreements was dependent upon
several factors, including the future earnings and value of MPS.

        On June 26, 1998 the Company, MPS and the executives entered into a
Restructure Agreement which terminated the options. In exchange for the
termination of the options the Company entered into a deferred compensation
arrangement with the executives that requires the Company to pay equal annual
installments of $1,180,000 to the executives over the three year period
beginning June 26, 1999, as long as the executive continues employment with the
Company. If the executive is terminated without cause all remaining amounts due
under the deferred compensation arrangement become immediately payable.

        The Company also granted loans totaling $3,040,000 to the executives
repayable in three equal annual installments, plus interest at 5.7% per annum,
beginning June 30, 1999. The loans are secured by the stock that each executive
owns, which aggregates approximately 19% of the outstanding shares of MPS. If
the executive terminates for any reason prior to the end of the three year
period, all remaining amounts under the note become immediately payable.


                                       14


<PAGE>   15
        Included in the Restructure Agreement is an additional provision that
requires the Company to pay to one of the executives $93,334 every six months,
beginning June 30, 1998, over the next three years, contingent upon continued
employment.

        The financial statement impact of these new agreements for the three and
six months periods ending June 30, 1998 was to record compensation expense
totaling $93,334.

        Securitization

        The Company completed its first mortgage loan securitization on June 29,
1998. The company retained the servicing responsibilities for the loans. The
Company recorded a net gain of $1,908,000 or 3.74% of the principal balance of
the loans sold, which represents the excess of the cash received and assets
retained by the Company over the relative fair value of the loans sold, less
transaction costs.. The assumptions used in the calculation of the gain on the
sale of the loans and the valuation of the residual interest in the
securitization of mortgage loans were as follows:

        The Company purchased a mortgage pool insurance policy that will cover
all losses up to 5% of the initial pool balances. The fee is .52% annually of
the unpaid principal of the loans. The net loss assumption used in calculating
the gain on sale of loans taking the policy into effect was .40% for the fixed
rate loans and .50% for the adjustable rate loans.

        In addition, to facilitate the sale, the Company provided a credit
enhancement for the benefit of the investors in the form of additional
collateral held by the trust. The over-collateralization account was required by
the servicing agreement to be maintained at certain levels.

        The residual interests in the securitization of loans represent the
present value of the difference between the contractual interest rates on the
loans and the rate paid to the buyer or bondholder using the assumptions
discussed above. The residual interest is accounted for as a trading security
and as such is recorded at its estimated fair value. The Company is not aware of
an active market for the purchase or sale of the residual interests.
Accordingly, the Company determined the estimated fair value of the residual
interests by discounting the expected cash flows released from the trust (the
cash out method) using a discount rate which the Company believes is
commensurate with the risks involved.

Loans or Tranche D Loans pursuant to a Borrowing Request which is received by
Agent not later than 11:00 a.m. (Dallas, Texas) time, on the day on which such
Loans are to be advanced. Each Borrowing Request shall constitute a request for
both (1) a Swing-Line Loan to be funded by Guaranty Federal and the Loans to be
made by Lender to refinance that Swing-Line Loan, and (2) if Guaranty Federal
elects not to make a Swing-Line Loan, the Loans actually requested by the text
of the Borrowing Request to be funded by the Lenders. If all conditions
precedent to such Loan have been met and Agent has notified each Lender that
Guaranty Federal has elected not to make a Swing-Line Loan pursuant to such
Borrowing Request, each Lender will on the date requested promptly remit to
Agent at Agent's office in Dallas, Texas the amount of such Lender's Tranche A
Loan, Tranche B Loan, Tranche C Loan or Tranche D Loan, as applicable, in
immediately available dollars, and upon receipt of such funds, unless to its
actual knowledge any conditions precedent to such Loan have been neither met nor
waived as provided herein, Agent shall promptly make such Loan available to
Borrower by crediting the Funding Account with a like amount of immediately
available funds. Guaranty Federal shall, not later than 3:00 p.m. (Dallas, Texas
time) on the date on which it makes any Swing-Line Loan, deposit the amount
thereof into the Funding Account. Each Borrowing Request shall be irrevocable
and binding on Borrower. Unless Agent shall have received prompt notice from a
Lender that such Lender will not make available to Agent such Lender's Loan,
Agent may in its discretion assume that such Lender has made such Loan available
to Agent in accordance with this section and Agent may if it chooses, in
reliance upon such assumption, make such Loan available to Borrower. If and to
the extent such Lender shall not so make its Loan available to Agent, such
Lender and Borrower severally agree to pay or repay to Agent within three days
after demand the amount of such Loan together with interest thereon, for each
day from the date such amount is made available to Borrower until the date such
amount is paid or repaid to Agent, at (i) the Federal Funds Rate, if such Lender
is making such payment and (ii) the interest rate applicable at the time to the
other Loans made on such date, if Borrower is making such repayment; Agent shall
use its best efforts to demand any such amount from both such Lender and
Borrower, provided, that any failure by Agent to make any such demand on both
such Lender and Borrower shall not in any manner affect such Lender's and
Borrower's obligation to pay or repay such amount, with interest, as set forth
herein. The failure of any Lender to make any Loan to be made by it hereunder
shall not relieve any other Lender of its obligation hereunder, if any, to make
its Loan, but no Lender shall be responsible for the failure of any other Lender
to make any Loan to be made by such other Lender.

        Section 2.04 Fees.

        (a) In consideration of each Lender's commitment to make Tranche A

1, 1998, and continuing regularly on each October 1, January 1, April 1 and July

interest, interest shall accrue and be payable thereon for the period of such
extension as provided in the Loan Document under which such payment is due. Each
payment under a Loan Document shall be payable at the place provided therein
and, if no specific place of payment is provided, shall be payable at the place
of payment of the Notes. When Agent collects or receives money on account of the
Obligations, Agent shall distribute all money so collected or received, and
Agent and Lenders shall apply all such money so distributed, as follows:

                (a) first, for the payment of all Obligations which are then
        due, and if such money is insufficient to pay all such Obligations, (i)
        first to any reimbursements due Agent under Section 5.05, (ii) second to
        Guaranty Federal for the payment of any outstanding Swing-Line Loans
        then due if such Swing-Line Loans are of the type which Lenders are
        obligated to refund pursuant to Section 2.07(c) below, (iii) third if
        such payments are on account of the Tranche A Loans, to the payment of
        the Tranche A Loans then due, if such payments are on account of the
        Tranche B Loans, to the payment of the Tranche B Loans then due, if such
        payments are on account of the Tranche C Loans, to the Tranche C Loans
        then due, if such payments are on account of the Tranche D Loans, to the
        payment of the Tranche D Loans then due, (iv) fourth to Guaranty Federal
        for the payment of any outstanding Swing-Line Loans then due which are
        of the type which Lenders are not obligated to refund pursuant to
        Section 2.07(c) below, and (v) then to the partial payment of all other
        Obligations then due in proportion to the amounts thereof, or as Lenders
        shall otherwise agree;


<PAGE>   32
                (b) then for the prepayment of amounts owing under the Loan
        Documents if so specified by Borrower;

                (c) then for the prepayment of principal on the Notes, together
        with accrued and unpaid interest on the principal so prepaid; and

                (d) last, for the payment or prepayment of any other
        Obligations.

All payments applied to principal or interest on any Note shall be applied first
to any interest then due and payable, then to principal then due and payable,
and last to any prepayment of principal and interest. All distributions of
amounts described in any of subsections (b), (c) or (d) above shall be made by
Agent pro rata to Agent and each Lender then owed Obligations described in such
subsection in proportion to all amounts owed to all Lenders which are described
in such subsection.

        Section 2.07 Refinancing of Swing-Line Loans.

        (a) Permitted Refinancings of Swing-Line Loans. Guaranty Federal, at any
time in its sole and absolute discretion, may, upon notice given to each other
Lender by not later than 12:00 noon (Dallas time) on any Business Day, request
that each Lender (including Guaranty Federal) make a Tranche A Loan, Tranche B
Loan, Tranche C Loan or Tranche D Loan, as applicable, in an aggregate amount
equal to its Percentage Share of the aggregate unpaid principal amount of any
outstanding Swing-Line Loans for the purpose of refinancing such Swing-Line
Loans.

        (b) Mandatory Refinancings of Swing-Line Loans. Not later than 12:00
noon (Dallas time) on the penultimate Business Day of each week, Guaranty
Federal will notify each other Lender of the aggregate amount of Swing-Line
Loans which are then outstanding and the amount of the Tranche A Loan, Tranche B
Loan, Tranche C Loan or Tranche D Loan required to be made by each Lender
(including Guaranty Federal) to refinance such outstanding Swing-Line Loans (the
aggregate amount of Loans to be made by each Lender shall equal such Lender's
Percentage Share of such outstanding Swing-Line Loans).

        (c) Lenders' Obligation to Fund Refinancings of Swing-Line Loans. Upon
the giving of notices by Guaranty Federal under Section 2.07(a) or 2.07(b), each
Lender (including Guaranty Federal) shall promptly remit to Agent at Agent's
office in Dallas, Texas, the amount equal to its Percentage Share of the
aggregate principal amount of Swing-Line Loans to be refinanced, in immediately
available funds, by not later than 3:00 p.m. (Dallas time) on the date such
notice was received, provided, however, that a Lender shall not be obligated to
make any such Tranche A Loan, Tranche B Loan, Tranche C Loan or Tranche D Loan,
unless (A) Guaranty Federal believed in good faith that all conditions to making
the subject Swing-Line Loan were satisfied at the time such Swing-Line Loan was
made, or (B) if the conditions to such Swing-Line Loan were not satisfied, the
satisfaction of such conditions have been waived in a writing by Majority
Lenders in accordance with the provisions of this Agreement. The proceeds of
Tranche A Loans, Tranche B Loans, Tranche C Loans and Tranche D Loans made
pursuant to the preceding sentence shall be paid to Guaranty Federal (and not to
Borrower) and applied to the payment of principal of the outstanding Swing-Line
Loans, and Borrower authorizes Agent to charge the Operating Account or any
other account (other than escrow or custodial accounts) maintained by it with
Agent (up to the amount available therein) in order to immediately pay Guaranty
Federal the principal amount of such Swing-Line Loans to the extent amounts
received from the other Lenders are not sufficient to repay in full the
principal of the outstanding Swing-Line Loans requested or required to be
refinanced. Upon the making of a Tranche A Loan, Tranche B Loan, Tranche C Loan
or Tranche D Loan by a Lender pursuant to this Section 


<PAGE>   33
2.07(c), the amount so funded shall become due under such Lender's Note and the
outstanding principal amount of the Swing-Line Loans shall be correspondingly
reduced. If any portion of any such amount paid to Guaranty Federal should be
recovered by or on behalf of Borrower from Guaranty Federal in bankruptcy or
otherwise, the loss of the amount so recovered shall be ratably shared among all
the Lenders in the manner contemplated by Section 9.06. Each Lender's obligation
to make Tranche A Loans, Tranche B Loans, Tranche C Loans and Tranche D Loans
pursuant to this Section 2.07(c) shall, subject to the proviso to the first
sentence of this Section 2.07(c), be absolute and unconditional and shall not be
affected by any circumstances, including, without limitation, (1) any setoff,
counterclaim, recoupment, defense or other right which such Lender may have
against Guaranty Federal, Borrower or anyone else for any reason whatsoever; (2)
the occurrence or continuance of an Event of Default or Default; (3) any adverse
change in the condition (financial or otherwise) of Borrower; (4) any breach of
this Agreement by Borrower, Agent or any Lender; or (5) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing;
provided, that in no event shall a Lender be obligated to make a Tranche A Loan,
Tranche B Loan, Tranche C Loan or Tranche D Loan pursuant to this Section
2.07(c) if, after giving effect thereto, the outstanding principal balance of
such Lender's Loans would exceed its Percentage Share of the Commitment.

        Section 2.08 Capital Reimbursement. If either (a) the introduction or
implementation of or the compliance with or any change in or in the
interpretation of any law, rule or regulation, or (b) the introduction or
implementation of or the compliance with any request, directive or guideline
from any central bank or other governmental authority (whether or not having the
force of law) affects or would affect the amount of capital required or expected
to be maintained by any Lender or any corporation controlling such Lender, then,
upon demand by such Lender, Borrower will pay to Agent for the account of such
Lender, from time to time as specified by such Lender, such additional amount or
amounts which such Lender shall determine to be appropriate to compensate such
Lender or any corporation controlling such Lender in light of such
circumstances, to the extent that such Lender reasonably determines that the
amount of any such capital would be increased or the rate of return on any such
capital would be reduced by or in whole or in part based on the face amount of
such Lender's Note or commitments under this Agreement.

        Section 2.09 Increased Cost of Loans. If any applicable domestic or
foreign law, treaty, rule or regulation (whether now in effect or hereinafter
enacted or promulgated, including Regulation D) or any interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof (whether or not having the force of
law):

        (a) shall change the basis of taxation of payments to any Lender of any
principal, interest, or other amounts attributable to any Loan bearing interest
at the Eurodollar Rate (a "Eurodollar Loan") or otherwise due under this
Agreement in respect of any Eurodollar Loan (other than taxes imposed on the
overall net income of such Lender or any lending office of such Lender by any
jurisdiction in which such Lender or any such lending office is located); or

        (b) shall change, impose, modify, apply or deem applicable any reserve,
special deposit or similar requirements in respect of any Eurodollar Loan
(excluding those for which such Lender is fully compensated pursuant to
adjustments made in the definition of any Adjusted Eurodollar Rate) or against
assets of, deposits with or for the account of, or credit extended by, such
Lender; or

        (c) shall impose on any Lender or the interbank Eurocurrency deposit
market any other condition relating to any Eurodollar Loan, the result of which
is to increase the cost to any Lender of funding or maintaining any Eurodollar
Loan or to reduce the amount of any sum receivable by any Lender in respect of
any Eurodollar Loan by an amount deemed by such Lender to be material,


<PAGE>   34
then such Lender shall promptly notify Agent and Borrower in writing of the
happening of such event and Borrower shall upon demand pay to Agent for the
account of such Lender such additional amount or amounts as will compensate such
Lender for such event (on an after-tax basis, taking into account any taxes on
such compensation).

        Section 2.10 Availability. If (a) any change in applicable laws,
treaties, rules or regulations or in the interpretation or administration
thereof of or in any jurisdiction whatsoever, domestic or foreign, shall make it
unlawful or impracticable for any Lender to fund or maintain Loans which bear
interest at the Eurodollar Rate, or shall materially restrict the authority of
any Lender to purchase or take offshore deposits of dollars (i.e.,
"Eurodollars"), or (b) any Lender determines that matching deposits appropriate
to fund or maintain loans bearing interest at the Eurodollar Rate are not
available to it, or (c) any Lender determines that the formula for calculating
the Adjusted Eurodollar Rate does not fairly reflect the cost to any Lender of
making or maintaining loans based on such rate, then, upon notice by such Lender
to Borrower and Agent, all Loans of such Lender which are then outstanding or
are then the subject of any Borrowing Request and which cannot lawfully or
practicably be maintained or funded based on the Eurodollar Rate shall
immediately begin bearing interest at the Back-Up Rate. Borrower agrees to
indemnify each Lender and hold it harmless against all costs, expenses, claims,
penalties, liabilities and damages which may result from any such change in law,
treaty, rule, regulation, interpretation or administration. Such indemnification
shall be on an after-tax basis, taking into account any taxes imposed on the
amounts paid as indemnity.

        Section 2.11 Reimbursable Taxes. Borrower covenants and agrees that:

        (a) Borrower will indemnify Agent and each Lender against and reimburse
Agent and each Lender for all present and future income, stamp and other taxes,
levies, costs and charges whatsoever imposed, assessed, levied or collected on
or in respect of this Agreement or any Loans bearing interest at the Eurodollar
Rate (whether or not legally or correctly imposed, assessed, levied or
collected), excluding, however, any taxes imposed on or measured by the overall
net income of Agent or such Lender or any lending office of Agent or such Lender
by any jurisdiction in which Agent or such Lender or any lending office is
located (all such non-excluded taxes, levies, costs and charges being
collectively called "Reimbursable Taxes" in this section). Such indemnification
shall be on an after-tax basis, taking into account any taxes imposed on the
amounts paid as indemnity.

        (b) All payments on account of the principal of, and interest on, each
Lender's Loan, each Lender's Note, and the Swing-Line Note and all other amounts
payable by Borrower to Agent and each Lender hereunder, shall be made in full
without set-off or counterclaim and shall be made free and clear of and without
deductions or withholdings of any nature by reason of any Reimbursable Taxes,
all of which will be for the account of Borrower. In the event of Borrower being
compelled by law or other regulations to make any such deduction or withholding
from any payment to Agent or any Lender, Borrower shall pay on the due date of
such payment, by way of additional interest, such additional amounts as are
needed to cause the amount receivable by Agent or such Lender after such
deduction or withholding to equal the amount which would have been receivable in
the absence of such deduction or withholding. If Borrower should make any
deduction or withholding as aforesaid, Borrower shall within 60 days thereafter
forward to Agent or such Lender an official receipt or other official document
evidencing payment of such deduction or withholding.

        Section 2.12 Notice of Certain Events; Change of Applicable Lending
Office. Each Lender agrees to provide written notice to Borrower of the
occurrence of any event (a "Triggering Event") described in Sections 2.08, 2.09,
2.10 or 2.11, which would give rise to any costs, expenses, claims, 


<PAGE>   35
penalties, liabilities, damages or Reimbursable Taxes, within sixty (60) days of
the date such Lender first learns of the occurrence of such Triggering Event
(the "Trigger Date"). If any Lender fails to provide written notice to Borrower
of a Triggering Event in accordance with the immediately preceding sentence,
Borrower shall be liable for only those costs, expenses, claims, penalties,
liabilities, damages or Reimbursable Taxes with respect to such Lender which
arose during the period beginning 120 days prior to the Trigger Date and ending
on the Trigger Date.

                                   ARTICLE III

        Each of Borrower and Guarantor represents and warrants as follows:

        Section 4.01 Organization and Good Standing. Each Related Person (a) is
a corporation duly incorporated and existing in good standing under the laws of
the jurisdiction of its incorporation, (b) is duly qualified as a foreign
corporation and in good standing in all jurisdictions in which its failure to be
so qualified could have a Material Adverse Effect, (c) has the corporate power
and authority to own its properties and assets and to transact the business in
which it is engaged and is or will be qualified in those states wherein it
proposes to transact business in the future and (d) is in compliance with all
Requirements of Law except to the extent that the failure to comply therewith
could not, in the aggregate, have a Material Adverse Effect.

        Section 4.02 Authorization and Power. Each Related Person has the
corporate power and requisite authority to execute, deliver and perform the Loan
Documents to which it is a party; each Related Person is duly authorized to and
has taken all corporate action necessary to authorize it to, execute, deliver
and perform the Loan Documents to which it is a party and is and will continue
to be duly authorized to perform such Loan Documents.

        Section 4.03 No Conflicts or Consents. Neither the execution and
delivery by any Related Person of the Loan Documents to which it is a party, nor
the consummation of any of the transactions herein or therein contemplated, nor
compliance with the terms and provisions hereof or with the terms and provisions
thereof, will (a) materially contravene or conflict with any Requirement of Law
to which any Related Person is subject, or any indenture, mortgage, deed of
trust, or other agreement or instrument to which any Related Person is a party
or by which any Related Person may be bound, or to which the Property of any
Related Person may be subject, or (b) result in the creation or imposition of
any Lien, other than the Lien of the Security Agreement, on the Property of any
Related Person. All actions, approvals, consents, waivers, exemptions,
variances, franchises, orders, permits, authorizations, rights and licenses
required to be taken, given or obtained, as the case may be, from any
Governmental Authority that are necessary in connection with the transactions
contemplated by the Loan Documents have been obtained.

        Section 4.04 Enforceable Obligations. This Agreement, the Notes, the
Swing-Line Note, and the other Loan Documents to which any Related Person is a
party are the legal, valid and binding obligations of such Related Person,
enforceable in accordance with their respective terms, except as limited by
Debtor Laws.

        Section 4.05 Priority of Liens. Upon delivery to Agent of each Borrowing
Request, Agent shall have valid, enforceable, perfected, first priority Liens
and security interests in each Mortgage Note identified therein, except to the
extent that the requirements for perfection have not been completed with respect
to Eligible Mortgage Loans for which Agent has received an Agreement to Pledge.


<PAGE>   38
        Section 4.06 No Liens. Borrower has good and indefeasible title to the
Mortgage Collateral and to all of the Eligible REO free and clear of all Liens
and other adverse claims of any nature, except for ad valorem taxes and
assessments not yet due and payable and Liens in the Mortgage Collateral or the
Eligible REO in favor of Agent.

        Section 4.07 Financial Condition of Borrower and Guarantor. Each of
Borrower and Guarantor has delivered to Agent and each Lender copies of their
annual audited balance sheet as of December 31, 1997, and the related statements
of income, stockholders' equity and cash flows for the period ended such date;
such financial statements fairly present the financial condition of each of
Borrower and Guarantor, respectively as of such date and the results of
operations of Borrower for the period ended on such date and have been prepared
in accordance with GAAP, subject to normal year-end adjustments; as of the date
thereof, there were no obligations, liabilities or Indebtedness (including
material contingent and indirect liabilities and obligations or unusual forward
or long-term commitments) of Borrower which are not reflected in such financial
statements and no change which constitutes a Material Adverse Effect has
occurred in the financial condition or business of (i) Borrower since March 31,
1998 and (ii) Guarantor since March 31, 1998. Borrower has also delivered to
Agent and each Lender its unaudited quarterly balance sheet for the period
ending March 31, 1998 and management reports for the months ended March 31,
1998; such reports fairly and accurately present Borrower's commitment position,
pipeline position, servicing and production as of the end of such months and for
the fiscal year to date for the periods ending on such dates. Guarantor has also
delivered to Agent and each Lender its unaudited quarterly balance sheet for the
period ending March 31, 1998; such report fairly and accurately presents
Guarantor's financial condition for the fiscal period ending on such date.

        Section 4.08 Full Disclosure. There is no material fact that Borrower or
Guarantor has not disclosed to Agent and each Lender which could adversely
affect the properties, business, prospects or condition (financial or otherwise)
of the Related Persons, or could adversely affect the Mortgage Collateral or the
Servicing Rights. To the best knowledge of each of Borrower and Guarantor,
neither the financial statements referred to in Section 4.07 hereof, nor any
Borrowing Request, officer's certificate or statement delivered by any Related
Person to Agent and each Lender in connection with this Agreement, contains any
untrue statement of material fact.

        Section 4.09 No Default. No Related Person is in default under any loan
agreement, mortgage, security agreement or other material agreement or
obligation to which it is a party or by which any of its Property is bound.

        Section 4.10 No Litigation. There are no material actions, suits or
legal, equitable, arbitration or administrative proceedings pending, or to the
knowledge of Borrower or Guarantor threatened, against any Related Person the
adverse determination of which could constitute a Material Adverse Effect.

        Section 4.11 Taxes. All tax returns required to be filed by each Related
Person in any jurisdiction have been filed and all taxes, assessments, fees and
other governmental charges upon each Related Person or upon any of its
properties, income or franchises have been paid prior to the time that such
taxes could give rise to a Lien thereon, unless protested in good faith by
appropriate proceedings and with respect to which reserves in conformity with
GAAP have been established on the books of such Related Person. No Related
Person has any knowledge of any proposed tax assessment against any Related
Person.

material compliance with ERISA.

        (a) Each Related Person has all permits and licenses necessary for the
operation of its business.

respect to the foregoing, which are necessary for the operation of its business,
without any known material conflict with the rights of other. The consummation
of the transactions contemplated hereby will not alter or impair in any material
respect any of such rights of each Related Person.

warranties by each of Borrower and Guarantor herein shall survive delivery of

        Section 4.22 Individual Mortgage Loans. Borrower hereby represents with
respect to each Mortgage Note and Mortgage Loan that is part of the Collateral:

        (a) Borrower has good and marketable title to each Mortgage Note and
Mortgage, was the sole owner thereof and had full right to pledge the Mortgage
Loan to Agent free and clear of any other Lien;

        (b) To the best knowledge of Borrower, there is no default, breach,
violation or event of acceleration existing under any Mortgage or the related
Mortgage Note (other than with respect to Repurchased Defaulted Mortgages) and
there is no event which, with the passage of time or with notice and/or the
expiration of any grace or cure period, would constitute a default, breach,
violation or event of acceleration and no such default, breach, violation or
event of acceleration has been waived;

        (c) To the best of the knowledge of Borrower, the physical condition of
the Property subject to the Mortgage has not deteriorated since the date of
origination of the related secured Mortgage Loan (normal wear and tear excepted)
and there is no proceeding pending for the total or partial condemnation of any
Mortgaged Property;

        (d) Each Mortgage contains customary and enforceable provisions such as
to render the rights and remedies of the holder thereof adequate for the
realization against the related Property subject to the Mortgage of the benefits
of the security provided thereby, including, (i) in the case of a Mortgage
designated as a deed of trust, by trustee's sale, and (ii) otherwise, by
judicial foreclosure;

        (e) Each Mortgage Loan is a first or second lien one-to-four-family
loan, and has been underwritten by the originator thereof in accordance with
such originator's then current underwriting guidelines;

        (f) Each Mortgage Note (other than with respect to Eligible Tranche C
Mortgage Loans) is payable in monthly installments of principal and interest,
with interest payable in arrears, and requires a monthly payment which is
sufficient to amortize the original principal balance over the original term 


<PAGE>   41
and to pay interest at the related interest rate; and no Mortgage Note (except
for any Mortgage Note evidencing an Eligible Tranche C Mortgage Loan) provides
for any extension of the original term;

        (g) Except for Eligible Manufactured Housing Mortgage Loans, no Mortgage
Loan is a loan in respect of the purchase of a Manufactured Home or mobile home
or the land on which a Manufactured Home or mobile home will be placed;

        (h) The origination practices used by the originator of the Mortgage
Loans and the collection practices used by the Borrower with respect to each
Mortgage Loan have been in all material respects legal, proper, prudent and
customary in the loan origination and servicing business;

        (i) Each Mortgage Loan was originated in compliance with all applicable
laws and no fraud or misrepresentation was committed by any Person in connection
therewith; and

        (j) Any Eligible Manufactured Housing Mortgage Loan originated in the
State of Texas, was originated pursuant to Section 347 of the Texas Finance
Code.

        Section 4.23 Environmental Matters. In the ordinary course of each
Related Person's business, the officers and managers of each Related Person
consider the effect of Environmental Laws on the business of such Related
Person, in the course of which they identify and evaluate potential risks and
liabilities accruing to such Related Person due to Environmental Laws. On the
basis of this consideration, each Related Person has reasonably concluded that
neither violation of nor compliance with Environmental Laws can reasonably be
expected to have a material adverse effect on the business or financial
condition of such Related Person or on the ability of Borrower to perform the
Obligations. No Related Person has received any notice to the effect that its
operations are not in material compliance with any of the requirements of
applicable Environmental Laws or are the subject of any federal or state
investigation evaluating whether any remedial action is needed to respond to a
release of any toxic or hazardous waste or substance into the environment, which
non-compliance or remedial action could reasonably be expected to have a
material adverse effect on the business or financial condition of the Related
Persons, taken as a whole, or on the ability of Borrower to perform the
Obligations.

business operations, or financial reporting of such property or entity
(collectively, the "systems") will properly perform date sensitive functions

        maintain such authorizations in full force and effect.

                (b) Borrower will promptly furnish to Agent all written notices
        of violation, orders, claims, citations, complaints, penalty
        assessments, suits or other proceedings received by Borrower, or of
        which it has notice, pending or threatened against Borrower, by any
        governmental authority with respect to any alleged violation of or
        non-compliance with any Environmental Laws or any permits, licenses or
        authorizations in connection with its ownership or use of its properties
        or the operation of its business.

                                 INDEMNIFICATION

        Section 8.01 Indemnification. Each of Borrower and Guarantor agrees to
indemnify Agent and each Lender and each director, officer, agent, attorney,
employee, representative and Affiliate of Agent and each Lender (each an
"Indemnified Party"), upon demand, from and against any and all liabilities,
obligations, claims, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements (including reasonable fees of attorneys,
accountants, experts and advisors) of any kind or nature whatsoever (in this
Section 8.01 collectively called "liabilities and costs") which to any extent
(in whole or in part) may be imposed on, incurred by, or asserted against any
Indemnified Party growing out of, resulting from or in any other way associated
with any of the Mortgage Collateral, the Loan Documents, any Mortgage Loan
originated for the construction of a Construction Home, and the transactions and
events (including the enforcement or defense thereof) at any time associated
therewith or contemplated therein (including any violation or noncompliance with
any Environmental Laws by any Related Person).

        THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH
        LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR
        IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED IN
        WHOLE OR PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY SUCH
        INDEMNIFIED PARTY,

provided only that such indemnified party shall be not entitled under this

and costs which is proximately caused by its own individual gross negligence or
willful misconduct. All amounts payable by Borrower and Guarantor shall be
immediately due upon Agent's request for the payment thereof.

                                   ARTICLE IX

                                      AGENT

        Section 9.01 Appointment and Authority. Each Lender hereby irrevocably
authorizes Agent, and Agent hereby undertakes, to receive payments of principal,
interest and other amounts due hereunder as specified herein to act as
Collateral agent and representative (within the meaning of Section 9.105(13) of
the UCC) for such Lender under the Security Agreement with such powers as are
reasonably incidental thereto, to act as secured party, agent, bailee and
custodian for the exclusive benefit of Lenders with respect to the Collateral,
and to take all other actions and to exercise such powers under the Loan
Documents as are specifically delegated to Agent by the terms hereof or thereof,
together with all other powers reasonably incidental thereto. The relationship
of Agent to Lenders is only that of one commercial bank acting as administrative
agent for others, the Agent's duties shall be purely ministerial, and nothing in
the Loan Documents shall be construed to constitute Agent a trustee or other
fiduciary for any holder of any of the Notes or of any participation therein nor
to impose on Agent duties and obligations other than those expressly provided
for in the Loan Documents. Agent shall not be required to exercise any
discretion or take any action, and it may request instructions from Lenders with
respect to any such matter, in which case it shall be required to act or to
refrain from acting (and shall be fully protected and free from liability to all
Lenders in so acting or refraining from acting) upon the instructions of
Majority Lenders (including itself), provided, however, that Agent shall not be
required to take any action which exposes it to a risk of personal liability
that it considers unreasonable or which is contrary to the Loan Documents or to
applicable law. Upon receipt by Agent from Borrower of any communication calling
for action on the part of Lenders or upon notice from any Lender to Agent of any
Default or Event of Default, Agent shall promptly notify each Lender thereof.
Each Lender hereby authorizes Agent to execute deliver and perform, in name of
and on behalf of such Lender, the Security Agreement. Agent may execute any of
its duties by or through agents or attorneys in fact.

        Section 9.02 Agent's Reliance, Etc. Neither Agent nor any of its
directors, officers, agents, attorneys, or employees shall be liable for any
action taken or omitted to be taken by any of them under or in connection with
the Loan Documents, including their negligence of any kind, except that each
shall be liable for its own gross negligence or willful misconduct. Without
limiting the generality of the foregoing, Agent (a) may treat the payee of any
Note as the holder thereof until Agent receives written notice of the assignment
or transfer thereof in accordance with this Agreement, signed by such payee and
in form satisfactory to Agent; (b) may consult with legal counsel (including
counsel for Borrower), independent public accountants and other experts selected
by it and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel, accountants or
experts; (c) makes no warranty or representation to any Lender and shall not be
responsible to any Lender for any statements, warranties or representations made
in or in connection with the Loan Documents; (d) shall not have any duty to
ascertain or to inquire as to the performance or observance of any of the terms,
covenants or conditions of the Loan Documents on the part of Borrower or the
value or sufficiency of the Collateral or to inspect the Property (including the
books and records) of Borrower; (e) shall not be responsible to any Lender for
the due execution, legality, validity, enforceability, genuineness, sufficiency
or value of any Loan Document or any instrument or document furnished in
connection therewith; (f) may rely upon the representations and warranties of
Borrower and the Lenders in exercising its powers hereunder; and (g) shall incur
no liability under or in respect of the Loan Documents by acting upon any
notice, consent, certificate or other instrument or writing (including any
telecopy, telegram, cable or telex) believed by it to be genuine and signed or
sent by the proper Person or Persons.


<PAGE>   55
        Section 9.03 Lenders' Credit Decisions. Each Lender acknowledges that it
has, independently and without reliance upon Agent or any other Lender in full
compliance with Lender's responsibilities under all applicable Governmental
Requirements (including but not limited to the due diligence requirements of
Banking Circular 181 promulgated by the Office of the Comptroller of the
Currency) based on its own commercial lending expertise has made its own
analysis of Borrower and the transactions contemplated hereby and its own
independent decision to enter into this Agreement and the other Loan Documents.
Each Lender as a sophisticated commercial lender has based its decision to make
the Loan upon a complete analysis of Borrower's credit quality, the value and
lien status of Collateral and the Loan Documents, conducted at the same level of
due diligence that Lender would undertake if it alone were making the Loan. Each
Lender also acknowledges that it will, independently and without reliance upon
Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Loan Documents. Each Lender's Loan is a
commercial loan transaction made in the ordinary course of Lender's business,
about which Lender, as a commercial lender, is fully informed and actively
involved on a daily basis. The Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Agent has received notice from a Lender or the Borrower referring to the Loan
Documents, describing such Default or Event of Default and stating that such
notice is a "notice of default." In the event the Agent receives such notice,
the Agent shall give notice thereof to the Lenders. The Agent shall take such
action with respect to such Default or Event of Default as directed by the
number of Lenders required for such action.

        Section 9.04 Indemnification. Each Lender agrees to indemnify Agent (to
the extent not reimbursed by Borrower within ten (10) days after demand) from
and against such Lender's Percentage Share of any and all liabilities,
obligations, claims, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements (including reasonable fees of attorneys,
accountants, experts and advisors) of any kind or nature whatsoever (in this
section, collectively, "liabilities and costs") which to any extent (in whole or
in part) may be imposed on, incurred by, or asserted against Agent, in its
capacity as Agent, growing out of, resulting from or in any other way associated
with any of the Collateral, the Loan Documents, any Mortgage Loan for the
construction of a one-to-four family residence, and the transactions and events
(including the enforcement thereof) at any time associated therewith or
contemplated therein. THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT
SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT OR BY STRICT LIABILITY, PROVIDED
ONLY THAT NO LENDER SHALL BE OBLIGATED UNDER THIS SECTION TO INDEMNIFY AGENT FOR
THAT PORTION, IF ANY, OF ANY LIABILITIES AND COSTS WHICH IS PROXIMATELY CAUSED
BY AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL
JUDGMENT. Cumulative of the foregoing, each Lender agrees to reimburse Agent
promptly upon demand for such Lender's Percentage Share of any costs and
expenses to be paid to Agent by Borrower under Section 5.05 to the extent that
Agent is not timely reimbursed for such expenses by Borrower as provided in such
section. As used in this section the term "Agent" shall refer not only to the
Person designated as such in Section 1.01 but also to each director, officer,
agent, attorney, employee, representative and Affiliate of such Person.

        Section 9.05 Rights as Lender. In its capacity as a Lender, Agent shall
have the same rights and obligations as any Lender and may exercise such rights
as though it were not Agent. Agent may accept deposits from, lend money to, act
as Trustee under indentures of, and generally engage in any 


                                       50


<PAGE>   56
kind of business with Borrower or its Affiliates, all as if it were not Agent
hereunder and without any duty to account therefor to any other Lender.

        Section 9.06 Sharing of Set-Offs and Other Payments. Each of Agent and
Lender agrees that if it shall, whether through the exercise of rights under
Security Instruments or rights of banker's lien, set off, or counterclaim
against Borrower or otherwise, obtain payment of a portion of the aggregate
Obligations owed to it which, taking into account all distributions made by
Agent under Section 2.06, causes Agent or such Lender to have received more than
it would have received had such payment been received by Agent and distributed
pursuant to Section 2.06, then (a) such Lender shall be deemed to have
simultaneously purchased and shall be obligated to purchase interests in the
Obligations as necessary to cause Agent and all Lenders to share all payments as
provided for in Section 2.06, and (b) such other adjustments shall be made from
time to time as shall be equitable to ensure that Agent and all Lenders share
all payments of Obligations as provided in Section 2.06; provided, however, that
nothing herein contained shall in any way affect the right of Agent or any
Lender to obtain payment (whether by exercise of rights of banker's lien,
set-off or counterclaim or otherwise) of indebtedness other than the
Obligations. Borrower expressly consents to the foregoing arrangements and
agrees that any holder of any such interest or other participation in the
Obligations, whether or not acquired pursuant to the foregoing arrangements, may
to the fullest extent permitted by law exercise any and all rights of banker's
lien, set-off, or counterclaim as fully as if such holder were a holder of the
Obligations in the amount of such interest or other participation. If all or any
part of any funds transferred pursuant to this section is thereafter recovered
from a Lender under this section which received the same, the purchase provided
for in this section shall be deemed to have been rescinded to the extent of such
recovery, together with interest, if any, if interest is required pursuant to
court order to be paid on account of the possession of such funds prior to such
recovery.

        Section 9.07 Investments. Whenever Agent in good faith determines that
it is uncertain about how to distribute to Lenders any funds which it has
received, or whenever Agent in good faith determines that there is any dispute
among Lenders about how such funds should be distributed, Agent may choose to
defer distribution of the funds which are the subject of such uncertainty or
dispute. If Agent in good faith believes that the uncertainty or dispute will
not be promptly resolved, or if Agent is otherwise required to invest funds
pending distribution to Lenders, Agent shall invest such funds pending
distribution; all interest on any such investment shall be distributed upon the
distribution of such investment and in the same proportion and to the same
Persons as such investment. All moneys received by Agent for distribution to
Lenders (including Agent in its separate capacity as a Lender) shall be held by
Agent pending such distribution solely as Agent for such Lenders, and Agent
shall have no equitable title to any portion thereof.

        Section 9.08 Benefit of Article IX. The provisions of this Article are
intended solely for the benefit of Agent and Lenders, and shall not be entitled
to rely on any such provision or assert any such provision in a claim or defense
against Agent or any Lender. Agent and Lenders may waive or amend such
provisions as they desire without any notice to or consent of Borrower.

        Section 9.09 Resignation. Agent may resign at any time by giving written
notice thereof to Lenders and Borrower. Each such notice shall set forth the
date of such resignation. Upon any such resignation Majority Lenders shall have
the right to appoint a successor Agent. A successor must be appointed for any
retiring Agent, and such Agent's resignation shall become effective when such
successor accepts such appointment. If, within thirty days after the date of the
retiring Agent's resignation, no successor Agent has been appointed and has
accepted such appointment, then the retiring Agent may appoint on behalf of the
Lenders a successor Agent, which shall be a Lender or commercial bank organized
or licensed to conduct a banking or trust business under the laws of the 


                                       51

United States of America or of any state thereof. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, the retiring Agent shall be
discharged from its duties and obligations under this Agreement and the other
Loan Documents. The successor Agent shall thereupon succeed to and become vested
with all rights, powers, privileges and duties and obligations as Agent under
the Loan Documents. The retiring Agent shall transfer all Collateral within its
possession or control to the successor Agent and shall execute and deliver such
notices, instructions and assignments as may be necessary or desirable to
transfer the rights of Agent with respect to the Collateral to the successor
Agent. After any retiring Agent's resignation as Agent, the provisions of this
Article IX and the provisions of the Loan Agreement providing for the
indemnification of Agent by Borrower or Lenders, shall continue in effect for
retiring Agent's benefit with respect to any of the actions taken or omitted to
be taken by it while acting as Agent.

        Section 9.10 NO REPRESENTATIONS. LENDERS ACKNOWLEDGE AND AGREE THAT
AGENT HAS MADE NO REPRESENTATION OR WARRANTY, WRITTEN OR ORAL, EXPRESS OR
IMPLIED, REGARDING THE ACCURACY OR COMPLETENESS OF ANY INFORMATION RELATING TO
BORROWER OR THE COLLATERAL INCLUDING BUT NOT LIMITED TO THE CREDITWORTHINESS OF
BORROWER OR ANY OBLIGOR, OR THE CONDITION OR COLLECTABILITY OF ANY ASSET. AGENT
AND ITS DIRECTORS, OFFICERS, AGENTS, ATTORNEYS, EMPLOYEES, REPRESENTATIVES AND
AFFILIATES SHALL HAVE NO LIABILITY TO ANY LENDER OR ANY OTHER PERSON RESULTING
FROM ANY SUCH INFORMATION.

MAY HAVE TO BE SUED ELSEWHERE. THE PARTIES HERETO CONSENT TO PERSONAL
JURISDICTION IN DALLAS COUNTY, TEXAS. SECTION 346 OF THE TEXAS FINANCE CODE
(WHICH REGULATES CERTAIN REVOLVING LOAN ACCOUNTS AND REVOLVING TRIPARTY
ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS.

        Section 10.03 Invalidity. In the event that any one or more of the
provisions contained in the Notes, this Agreement or any other Loan Document
shall, for any reason, be held invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other
provision of such document.

        Section 10.04 Survival of Agreements. All covenants and agreements
herein and in any other Loan Document not fully performed before the date hereof
or the date thereof, and all representations and warranties herein or therein,
shall survive until payment in full of the Obligations and termination of the
Commitment.

        Section 10.05 Renewal, Extension or Rearrangement. All provisions of
this Agreement and of the other Loan Documents shall apply with equal force and
effect to each and all promissory notes hereafter executed which in whole or in
part represent a renewal, extension for any period, increase or rearrangement of

of such other Obligations.

        Section 10.06 Waivers. No course of dealing on the part of Agent or any
Lender, or any of its officers, employees, consultants or agents, nor any

each Lender under the Notes, this Agreement, and any other Loan Document shall

        Section 10.08 Limitation on Interest. Agent, Lenders, each Related
Person and any other parties to the Loan Documents intend to contract in strict
compliance with applicable usury law from time to time in effect. In furtherance
thereof such Persons stipulate and agree that none of the terms and provisions
contained in the Loan Documents shall ever be construed to create a contract to
pay, for the use, forbearance or detention of money, interest in excess of the
maximum amount of interest permitted to be charged by applicable law from time
to time in effect. Neither each Related Person nor any present or future
guarantors, endorsers, or other Persons hereafter becoming liable for payment of
any Obligation shall ever be liable for unearned interest thereon or shall ever
be required to pay interest thereon in excess of the maximum amount that may be
lawfully charged under applicable law from time to time in effect, and the
provisions of this section shall control over all other provisions of the Loan
Documents which may be in conflict or apparent conflict herewith. Agent and
Lenders expressly disavow any intention to charge or collect excessive unearned
interest or finance charges in the event 


                                       54


<PAGE>   60
the maturity of any Obligation is accelerated. If (a) the maturity of any
Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a
result any amounts held to constitute interest are determined to be in excess of
the legal maximum, or (c) Agent or any Lender or any other holder of any or all
of the Obligations shall otherwise collect moneys which are determined to
constitute interest which would otherwise increase the interest on any or all of
the Obligations to an amount in excess of that permitted to be charged by
applicable law then in effect, then all such sums determined to constitute
interest in excess of such legal limit shall, without penalty, be promptly
applied to reduce the then outstanding principal of the related Obligations or,
at Agent's or such Lender's or such holder's option, promptly returned to each
Related Person or the other payor thereof upon such determination. In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable law, Agent,
Lenders and the each Related Persons (and any other payors thereof) shall to the
greatest extent permitted under applicable law, (i) characterize any
non-principal payment as an expense, fee or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable law in order to
lawfully charge the maximum amount of interest permitted under applicable law.
In the event applicable law provides for an interest ceiling under Section 303
of the Texas Finance Code, that ceiling shall be the weekly ceiling.

        Section 10.09 Bank Accounts; Offset. To secure the repayment of the
Obligations each Related Person hereby grants to Agent, each Lender and to each
financial institution which hereafter acquires a participation or other interest
in the Loans or Notes (in this section called a "Participant") a security
interest, a lien, and a right of offset, each of which shall be in addition to
all other interests, liens, and rights of Agent, any Lender or Participant at
common law, under the Loan Documents, or otherwise, and each of which shall be
upon and against (a) any and all moneys, securities or other property (and the
proceeds therefrom) of any Related Person now or hereafter held or received by
or in transit to Agent, any Lender or Participant from or for the account any
Related Person, whether for safekeeping, custody pledge, transmission,
collection or otherwise, (b) any and all deposits (general or special, time or
demand, provisional or final) of any Related Person with Agent, any Lender or
Participant, and (c) any other credits and claims of any Related Person at any
time existing against Agent, any Lender or Participant, including claims under
certificates of deposit. Upon the occurrence of any Default, each of Agent,
Lenders and Participants is hereby authorized to foreclose upon, offset,
appropriate, and apply, at any time and from time to time, without notice to
Borrower, any and all items hereinabove referred to against the Obligations then
due and payable.

transfer all or any part of such Lender's Note, Loans and rights and the
associated rights and obligations under all Loan Documents to one or more
financial institutions, with minimum assets of $5,000,000,000; provided, that
each such sale, assignment, or transfer shall be with the reasonable consent of
Agent, and the assignee, transferee or recipient shall have, to the extent of
such sale, assignment, or transfer, the same rights, benefits and obligations as
it would if it were such Lender and a holder of such Note, including, without
limitation, the right to vote on decisions requiring consent or approval of all
Lenders or Majority Lenders and the obligation to fund its Percentage Share of
any Loan directly to Agent; provided further, that (i) each Lender in making
each such sale, assignment, or transfer must dispose of a pro rata portion of
each Loan made by such Lender, (ii) each such sale, assignment, or transfer
shall be in a principal amount not less than $5,000,000, or the entire amount of
Lender's Percentage Share, if less than $5,000,000, (iii) each Lender shall at
all times maintain Loans then outstanding in an aggregate amount at least equal
to $5,000,000 (unless Lender transfers 100% of its Percentage Share), (iv) each
Lender may not offer to sell its Note and Loans or interests therein in
violation of any securities laws, and (v) no such assignments shall become
effective until (i) the assigning Lender delivers to Agent copies of all written
assignments and other documents evidencing any such assignment or related
thereto and the assignee Lender becomes a party to this Agreement.
Notwithstanding the provisions of clauses (ii) and (iii) above, a Lender may
make a sale, assignment or transfer, or maintain Loans then outstanding, in an
amount which is less than that required above provided that Borrower and such
Lender have agreed to modify such requirements and have delivered to Agent prior
written evidence of their agreement to make such modification. An assignment fee
in the amount of $2,500 for each such assignment will be payable to Agent by
assignor or assignee. Within five (5) Business Days after its receipt of notice
that the Agent has received copies of any assignment and the other documents
relating thereto, the assignee shall notify Borrower of the outstanding
principal balance of the Notes payable to such Lender and shall execute and
deliver to Agent (for delivery to the relevant assignee) new Notes evidencing
such assignee's assigned Loans and, if the assignor Lender has retained a
portion of its Loans, replacement Notes in the principal amount of the Loans
retained by the assignor Lender (such Notes to be in exchange for, but not in
payment of, the Notes held by such Lender).

        (b) Participations. Each Lender shall have the right to grant
participations in all or any part of such Lender's Note, Loans and the
associated rights and obligations under all Loan Documents to one or more
financial institutions with minimum assets of $5,000,000,000; provided that (i)
each Lender granting a participation shall use its best efforts to give prior
notice of any such participation, but in any event shall promptly notify Agent
and Borrower thereof, (ii) each Lender granting a participation shall retain the
right to vote hereunder, and no participant shall be entitled to vote hereunder
on decisions requiring consent or approval of Majority Lenders (except as set
forth in (iv) below), (iii) each Lender and Borrower shall be entitled to deal
with the Lender granting a participation in the same manner as if no
participation had been granted, and (iv) no participant shall ever have any
right by reason of its participation to exercise any of the rights of Lenders
hereunder, except that any Lender may agree with any participant that such
Lender will not, without the consent of such participant, consent to any
amendment or waiver described in Section 10.02 requiring approval of 100% of the
Lenders.

        (c) Distribution of Information. It is understood and agreed that any
Lender may provide to assignees and participants and prospective assignees and
participants financial information and reports and data concerning Borrower's
properties and operations which was provided to such Lender pursuant to this
Agreement.
