day which is not a Business Day and payments received after 2:00 p.m. on any
Business Day shall be treated for all purposes as having been received on the

or would result from following the payment directions of the Borrower, payments
in respect of the Obligations shall be applied to specific types of Obligations

     with respect to this Agreement, the Note or any Advance made by it, or
     change the basis of taxation of payments to Bank One of principal, facility

     computation of the overall net income of Bank One that do not specifically
     involve payments to Bank One under this Agreement, the Note, or any
     Advance, even though such changes have the effect of increasing the
     effective rate of tax imposed on income of Bank One);

                 (ii)   shall impose, modify or hold applicable any reserve,
     special deposit, compulsory loan or similar requirement against assets held

demand, any additional amounts necessary to compensate Bank One for such
additional cost or reduced amount receivable.  A certificate as to any
additional amounts payable pursuant to the foregoing sentence submitted by Bank

regarding capital adequacy (whether or not having the force of law) from any
central bank or Governmental Authority issued after March 15, 1996, including,
without limitation, the issuance of any final rule, regulation or guideline,
does or shall have the effect of reducing the rate of return on Bank One's or
such corporation's capital as a consequence of its obligations hereunder to a
level below that which Bank One or such corporation could have achieved but for
such adoption, change or compliance (taking into consideration Bank One's or
such corporation's policies with respect to capital adequacy) by an amount
deemed by Bank One to be material, then the Borrower shall promptly pay Bank
One, upon its written demand setting forth the basis for such demand, any
additional amounts necessary to compensate Bank One or such corporation for such
reduced rate of return.  A certificate as to any additional amounts payable
pursuant to the foregoing sentence submitted by Bank One to the Borrower shall
be conclusive in the absence of manifest error.  This covenant shall survive the
termination of this Agreement and payment of the Note.

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

          (a)  Pursuant to Agency Commitments. Subject to the provisions of this
               ------------------------------
Agreement and compliance with the FNMA Guide, the FHLMC Guide or the GNMA Guide,
as applicable, Bank One shall deliver the Mortgage Documents which relate to
Pledged Mortgage Loans Allocated to a particular Agency Commitment to or for the
account of the relevant Agency and shall release the security interest of Bank
One to secure the Obligations therein. The Borrower shall complete each Agency
Form such that the Mortgage Backed Security to be issued or guaranteed pursuant
to a Pledged Agency Commitment is issued in the name of Bank One or its
designee, or, if issued in the name of the Borrower, is issued to an account
subject to the sole dominion and control of Bank One or its designee and shall
take such other steps as may be requested by Bank One to cause the security
interest of Bank One in and to any Mortgage Backed Security which constitutes
Proceeds of one or more Pledged Mortgage Loans to be a perfected, first-
priority, security interest. Without limiting the generality of the preceding
sentence, unless otherwise instructed by Bank One, the Borrower shall complete
each GNMA form Schedule of Subscribers such that "Manuf/Cust/FAO/Bank One"
appears as the Subscriber/PTC Participant; complete each FNMA form Delivery
Schedule such that "Bank One, Texas/Cust" appears as the Depository Institution
and Telegraphic Abbreviation and "1110-0061-4" appears as the ABA Number and
"NVR Mortgage Finance, Inc. 310118" appears as the Owners Account Name/Account
Number; and shall complete each FHLMC form Warehouse Lender Release of Security
Interests and FHLMC form Guarantor Program: Security Settlement Information and
Delivery Authorization such that "Bank One, Texas/Cust/NVR Mortgage Finance,
Inc./310118" appears as the Depository Institution/Type of
Account/Beneficiary/Account Number and such that "1110-0061-4" appears as the
ABA Number. Upon completion of its review of the Required Mortgage Documents and
the Agency Forms relevant to a particular Agency Commitment, Bank One shall
deliver such Agency Forms to the applicable Agency and shall deliver the
Required Mortgage Documents to or for the account of such Agency under a bailee
letter or such other form of transmittal letter as such Agency may require;
provided, that the release of the security interest in favor of Bank One in such
- --------
Required Mortgage Documents and the Mortgage Loans evidenced thereby shall be
conditioned upon receipt by Bank One or its designee of Mortgage Backed
Securities in the amount specified in the relevant Agency Commitment.

          (b)  Pursuant to Take-Out Commitments. Mortgage Backed Securities
               --------------------------------
which constitute Proceeds of Pledged Mortgage Loans shall be sold pursuant to
the Take-Out Commitments to which such Mortgage Backed Securities have been
Allocated. The Borrower agrees to take all steps necessary to satisfy the
conditions to the sale of any Mortgage Backed Security which constitutes
Proceeds of Pledged Mortgage Loans pursuant to the Take-Out Commitment to which
it has been

                                      198

 
Allocated. Mortgage Backed Securities from time to time included in the
Collateral shall be sold versus payment (and not "free"). In connection with the
sale of any Mortgage Backed Security included in the Collateral, Bank One shall
not be under any duty at any time to credit the Borrower for any amounts due
from any Person in respect of any purchase until Bank One has actually received
immediately available funds. Any funds so received will be treated as payments
under and processed and applied in accordance with Section 2.6. Bank One shall
                                                   -----------
not be under any duty at any time to collect any amounts or otherwise enforce
any obligations due from any Person in respect of any such purchase.

          (c)  Mandatory Redemption. In the event that the issuance of any
               --------------------
Mortgage Backed Security pursuant to an Agency Commitment has not occurred
within five (5) Business Days of the scheduled date for such issuance (as set
forth on the relevant Borrowing Request), the Borrower agrees to make a
prepayment of the Advances in an aggregate amount equal to the Collateral Value
(but for any event or circumstance which caused such failure) of the Mortgage
Loans intended to back such Mortgage Backed Security. In the event the sale of a
Mortgage Backed Security pursuant to a Take-Out Commitment has not settled
within five (5) Business Days of the scheduled settlement date for such sale (as
set forth in the relevant Borrowing Request), the Borrower agrees to make a
prepayment of the Advances in an aggregate amount equal to the Collateral Value
(but for any event or circumstance which caused such failure) of such Mortgage
Backed Security.

the Agency Commitment and the Take-Out Commitment identified thereon are both in
full force and effect and that all representations and warranties made or deemed
made by the Borrower to the Agency or Investor thereunder are true and correct.
Upon the delivery of the Borrowing Request by which such Pledged Mortgage Loan
is identified, the Borrower represents and warrants with respect to each Pledged
Mortgage Loan that:

     applicable Requirements of Law, including, without limitation, (i) any
     usury laws, (ii) the Real Estate Settlement Procedures Act of 1974, as
     amended, (iii) the Equal Credit Opportunity Act, as amended, (iv) the

     protection laws;

          (b)  the full Face Amount of such Pledged Mortgage Loan (less any
     discount points paid by or on behalf of the borrower under such Pledged
     Mortgage Loan) was funded to the borrower thereunder;

          (c)  such Pledged Mortgage Loan was underwritten in compliance with
     the requirements of the Agency under the Pledged Agency Commitment to which
     it has been Allocated and the Mortgage Backed Security to be issued or
     guaranteed pursuant to such Agency Commitment satisfies (or upon issuance
     thereof will satisfy) all requirements for purchase under the Pledged Take-
     Out Commitment to which it has been Allocated;

          (d)  the Mortgage related to such Pledged Mortgage Loan creates a
     perfected first-priority lien (subject only to exceptions permitted by the
     Agency obligated under the Agency Commitment to which such Mortgage Loan
     has been Allocated) on residential real property consisting of land and a
     one-to-four family dwelling thereon which is completed and ready for
     occupancy and such Mortgage, the other Principal Mortgage Documents, the
     title policy relevant thereto and the Other Mortgage Documents relevant
     thereto comply in all respects with the requirements of the Agency under
     the applicable Agency Commitment;

          (e)  such Pledged Mortgage Loan is an Eligible Mortgage Loan; and

          (f)  the Borrower has all requisite power and authority to grant Bank
     One a security interest to secure the Obligations in such Pledged Mortgage
     Loan.

               Section 3.6 Borrower Appointed Agent. Bank One hereby appoints
                           ------------------------
the Borrower (and, in the case of any Pledged Mortgage Loan originated by a
Person other than the Borrower, also appoints such other Person) as its agent at
the sole cost and expense of the Borrower for purposes of (a) obtaining
Appraisals with respect to the property covered by the Mortgages which relate to
the Pledged Mortgage Loans and (b) otherwise complying with Appraisal Laws and
Regulations.

                           ------------------
acknowledges that the Settlement Account is subject in all respects to the right
of offset in favor of Bank One granted under Section 10.10. The Settlement
                                             -------------
Account shall be subject to the sole dominion and control of Bank One, provided,
                                                                       --------
that so long as no Default or Event of Default exists or would result therefrom,
Bank One shall disburse sums on deposit in the Settlement Account in accordance
with the instructions of the Borrower.

     written notice thereof shall have been given to the Borrower by Bank One;

          (c)  the Borrower fails to observe or perform any of the covenants or
     agreements contained in any other Loan Document, and (unless such default

     applicable grace period which may be expressly allowed under such other
     Loan Document;

               Section 9.1 Indemnification.
                           --------------- 

          (a)  The Borrower will indemnify and hold harmless Bank One, Bank
One's directors, officers, employees and each Person, if any, who is deemed to
control Bank One (any and all of whom are referred to as the "Indemnified
                                                              -----------
Party") from and against any and all losses, claims, damages and liabilities,
- -----
joint or several (including all losses, claims, damages and liabilities
resulting from the negligence, but not the gross negligence of such Indemnified
Party, and including all legal fees or other expenses reasonably incurred by any
Indemnified Party in connection with the preparation for or defense of any
pending or threatened claim, action or proceeding, whether or not resulting in
any liability), to which such Indemnified Party may become subject (whether or
not such Indemnified Party is a party thereto) under any applicable Federal,
state or local law or otherwise caused by or arising out of, or allegedly caused
by or arising out of, this Agreement or any transaction contemplated hereby,
including, without limitation, any liability or penalty arising out of any fact
or circumstance which causes the representations and warranties set forth in
Section 3.5 to be false or incorrect, excepting only losses, claims, damages or
- -----------
liabilities resulting from the gross negligence or willful misconduct or fraud
of such Indemnified Party.

          (b)  Promptly after receipt by an Indemnified Party of notice of any
claim, action or proceeding with respect to which an Indemnified Party is
entitled to indemnity hereunder, such Indemnified Party will notify the Borrower
of such claim or the commencement of such action or proceeding, provided that
                                                                --------
the failure of an Indemnified Party to give notice as provided herein shall not
relieve the Borrower of its obligations under this Section 9.1 with respect to
                                                   -----------
such Indemnified Party, except to the extent that the Borrower is actually
prejudiced by such failure. The Borrower will assume the defense of such claim,
action or proceeding and will employ counsel reasonably satisfactory to the
Indemnified Party and will pay the reasonable fees and expenses of such counsel.
Notwithstanding the preceding sentence, the Indemnified Party will be entitled,
at the expense of the Borrower, to employ counsel separate from counsel for the
Borrower and for any other party in such action if the Indemnified Party
reasonably determines that a conflict of interest or other reasonable basis
exists which makes representation by counsel chosen by the Borrower not
advisable, provided that the Borrower shall not be obligated to pay for the fees
           --------
and expenses of more than one counsel for all Indemnified Parties in respect of
a particular controversy. In the event an Indemnified Party appears as a witness
in any action or proceeding brought against the Borrower or any of its
Subsidiaries (or any of its officers, directors or employees) in which an
Indemnified Party is not named as a defendant, the Borrower agrees to reimburse
such Indemnified Party for all reasonable expenses incurred by it (including
reasonable fees and expenses of counsel) in connection with its appearing as a
witness.

directors, officers, agents or employees of Bank One shall be liable for any
action taken or omitted to be taken by it or them under or in connection with
this Agreement, except for such actions taken or omitted to be taken as
constitute gross negligence or wilful misconduct on the part of Bank One or its
directors, officers, agents or employees.

OTHER LOAN DOCUMENT IS A CONTRACT MADE UNDER AND SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE UNITED STATES OF AMERICA AND THE
STATE OF TEXAS, AS SUCH LAWS ARE NOW IN EFFECT, EXCEPT AS OTHERWISE SPECIFIED
HEREIN OR THEREIN, AND, WITH RESPECT TO USURY LAWS, IF ANY, APPLICABLE TO BANK
ONE AND TO THE EXTENT ALLOWED THEREBY, AS SUCH LAWS MAY HEREAFTER BE IN EFFECT
WHICH ALLOW A HIGHER MAXIMUM NONUSURIOUS INTEREST RATE THAN SUCH LAWS NOW ALLOW.
TEX. REV. CIV. STAT. ANN. ART. 5069, CH. 15 (WHICH REGULATES CERTAIN REVOLVING
LOAN ACCOUNTS AND REVOLVING TRIPARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT
OR THE NOTE.

               Section 10.9 Interest. Any provisions herein, in the Note, or in
                            --------
any other Loan Document, or any other document executed or delivered in
connection herewith, or in any other agreement or commitment, whether written or
oral, expressed or implied, to the contrary notwithstanding, Bank One shall not
in any event be entitled to receive or collect, nor shall or may amounts
received hereunder be credited, so that Bank One shall be paid, as interest, a
sum greater than the maximum amount permitted by applicable law to be charged to
the Person primarily obligated to pay the Note at the time in question. If any
construction of this Agreement, the Note or any other Loan Document, or any and
all other papers, agreements or commitments indicate a different right given to
Bank One to ask for, demand or receive any larger sum as interest, such is a
mistake in calculation or wording which this clause shall override and control,
it being the intention of the parties that this Agreement, the Note, and all
other Loan Documents or other documents executed or delivered in connection
herewith shall in all things comply with applicable law and proper adjustments
shall automatically be made accordingly. In the event that Bank One shall ever
receive, collect or apply as interest, any sum in excess of the maximum
nonusurious rate permitted by applicable law (the "Maximum Rate"), if any, such
                                                   ------------
excess amount shall be applied to the reduction of the unpaid principal balance
of the Note, and if the same be paid in full, any remaining excess shall be paid
to the Borrower. In determining whether or not the interest paid or payable,
under any specific contingency, exceeds the Maximum Rate, if any, the Borrower
and Bank One shall, to the maximum extent permitted under applicable law: (a)
characterize any nonprincipal payment as an expense or fee rather than as
interest, (b) exclude voluntary prepayments and the effects thereof, and (c)
"spread" the total amount of interest throughout the entire term of the Note;
provided that if the Note is paid and performed in full prior to the end of the
full contemplated term hereof, and if the interest received for the actual
period of existence thereof exceeds the Maximum Rate, if any, the Person holding
the Note shall refund to the Borrower the amount of such excess.

     To the extent that TEX. REV. CIV. STAT. ANN. art 5069-1.04, as amended (the
"Act" is relevant to the holder of the Note for purposes of determining the
 ---
Maximum Rate, each such holder elects to determine such applicable legal rate
under the Act pursuant to the "indicated rate ceiling", from time to time in
effect, as referred to and defined in article 1.04(a)(1) of the Act; subject,
however, to the limitations on such applicable ceiling referred to and defined
in article 1.04(b)(2) of the Act, and further subject to any right such holder
may have subsequently, under applicable law, to change the method of determining
the Maximum Rate.

               Section 10.10 Right of Offset. The Borrower hereby grants to Bank
                             ---------------
One and to any assignee or participant of Bank One a right of offset, to secure
the repayment of the Obligations, upon any and all monies, securities or other
property of the Borrower, and the proceeds therefrom now or hereafter held or
received by or in transit to such Person, from or for the account of the
Borrower, whether for safekeeping, custody, pledge, transmission, collection or
otherwise, and also upon any and

                                      207

 
all deposits (general or special, time or demand, provisional or final) and
credits of the Borrower, and any and all claims of the Borrower against such
Person at any time existing. Upon the occurrence of any Event of Default, such
Person is hereby authorized at any time and from time to time, without notice to
the Borrower, to offset, appropriate, and apply any and all items hereinabove
referred to against the Obligations. Notwithstanding anything in this Section
                                                                      -------
10.10 or elsewhere in this Agreement to the contrary, neither Bank One nor any
- -----
assignee or participant of Bank One shall have any right to offset, appropriate
or apply any accounts of the Borrower which consist of escrowed funds (except
and to the extent of any beneficial interest of the Borrower in such escrowed
funds) on deposit in accounts which accounts have been identified on the books
and records of the Person with whom such accounts are maintained as containing
escrowed funds.

               Section 10.11 Successors and Assigns; Confidentiality. All
                             ---------------------------------------
covenants and agreements by or on behalf of the Borrower in the Note, this
Agreement, or any other Loan Document shall bind the Borrower's successors and
assigns and shall inure to the benefit of Bank One and its successors and
assigns. The Borrower shall not, however, have the right to assign its rights
