and all accrued interest thereon so recorded shall be conclusive evidence of the
principal amount and interest owing and unpaid on the Note, absent manifest
error. The failure to so record any such amount or any error in so recording any
such amount shall not, however, limit or otherwise affect the obligations of the
Borrower hereunder or under any Note to repay the principal amount of the Loans
together with all interest accruing thereon.

         SECTION 4  COMMITMENT

whatever source such reimbursement is received.

                (c)   The Borrower shall cause all monies received from
or in connection with the
Servicing Agreements and/or the Accounts which may be used by the Borrower to
reimburse itself for advances of any and all kinds that it has made pursuant to
the Servicing Agreements to be deposited in a segregated bank account maintained
with the Bank. Such deposits shall be made at the end of each Business Day when
the aggregate of such receipts since the date of the last such deposit exceed
$100,000.00. At the time such deposits are made, the Borrower shall send written
notice to the Bank as to the amount of any portion of such deposit that
represents monies that may only be used to reimburse the Borrower for P&I
Advances. The Bank is hereby irrevocably authorized and instructed, at the end
of each Business Day, to use all available funds on deposited in such bank
account to prepay any outstanding P&I Loans and/or T&I Loans, as the case may
be. The obligation to make deposits under this subsection (c) shall only be in
effect to the extent of the Loans outstanding from time to time hereunder.

   5.3   All Prepayments. Each voluntary partial prepayment shall be in a
principal amount of $100,000.00 or a higher integral multiple of $10,000.00.

then or thereafter with the Bank.

   5.5  Taxes. All payments of principal of, and interest on, the Loans and all
other amounts payable hereunder shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes and
other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, excluding franchise taxes and taxes
imposed on or measured by the Bank's gross or net income or receipts (all
non-excluded items being called "Taxes"). If any withholding or deduction from
any payment to

<PAGE>   11

be made by the Borrower hereunder is required in respect of any
Taxes pursuant to any applicable law, rule or regulation, then the Borrower

required to be so withheld or deducted;

                  (b) promptly forward to the Bank an official receipt or other
documentation satisfactory to the Bank evidencing such payment to such
authority; and

                  (c) pay to the Bank such additional amount or amounts as is
necessary to ensure that the net amount actually received by the Bank will equal
the full amount the Bank would have received had no such withholding or
deduction been required.

Moreover, if any Taxes are directly asserted against the Bank with respect to
any payment received by the Bank hereunder, the Bank may pay such Taxes and the
Borrower will promptly pay such additional amounts (including any penalty,
interest or expense) as is necessary in order that the net amount received by
such Person after the payment of such Taxes (including any Taxes on such
additional amount) shall equal the amount such Person would have received had
such Taxes not been asserted.

         If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Bank, the required receipts or other
required documentary evidence, the Borrower shall indemnify the Bank for any
incremental Taxes, interest or penalties that may become payable by the Bank as
a result of any such failure.

the contrary, the Bank shall have no obligation to make any further Loans
hereunder and the Bank may declare the full amount of all Loans outstanding
hereunder to be immediately due and payable if, within 90 days after the date
hereof: (a) the Bank shall not be reasonably satisfied with the results of a
field audit of the Borrower's business to be conducted by the Bank, at the
Borrower's expense, within such 90 day period and/or (b) the Bank shall not have
received a SAS 70 Report with respect to the Borrower, dated no earlier than the
Closing Date, and in form and substance satisfactory to the Bank. The Bank shall
give the Borrower at least five (5) Business Days notice if it determines that

and correct:

                 (a) the representations and warranties of the Borrower set
forth in this Agreement and the other Loan Documents shall be true and correct
in all material respects with the same effect as if then made (except to the
extent stated to relate to a specific earlier date, in which case such
representations and warranties shall be true and correct as of such earlier
date); and

                 (b) no Event of Default or Unmatured Event of Default shall
have then occurred and be continuing.
          7.27.2.2 Confirmatory Certificate. If requested by the Bank, the Bank
shall have received a certificate dated the date of such requested Loan and
signed by a duly authorized representative of the Borrower as to the matters set
out in Section 8.2.1 (it being understood that each request by the Borrower for
the making of a Loan shall be deemed to constitute a warranty by the Borrower
that the conditions precedent set forth in Section 8.2.1 will be satisfied at
the time of the making of such Loan), together with such other documents as the
Bank may reasonably request in support thereof.

      SECTION 8 EVENTS OF DEFAULT AND THEIR EFFECT.

hereunder or under any other Loan Document.

              8.18.1.2 Non-Payment of Other Debt. Any default shall occur under
the terms applicable to any Debt of the Borrower or any Subsidiary in an
aggregate amount (for all such Debt so affected) exceeding $500,000.00 and such
default shall (a) consist of the failure to pay such Debt when due, whether by
acceleration or otherwise, or (b) accelerate the maturity of such Debt or permit
the holder or holders thereof, or any trustee or agent for such holder or
holders, to cause such Debt to become due and payable (or require the Borrower
or any Subsidiary to purchase or redeem such Debt) prior to its expressed
maturity.

              8.18.1.3 Other Material Obligations. Default in the payment when
due, or in the performance or observance of, any material obligation of, or
condition agreed to by, the Borrower or any Subsidiary with respect to any
material purchase or lease of goods or services where such default, singly or in
the aggregate with all other such defaults, might reasonably be expected to have
a Material Adverse Effect.

              8.18.1.4 Bankruptcy, Insolvency, etc. Either Borrower becomes
insolvent or generally fails to pay, or admits in writing its inability or
refusal to pay, debts as they become due; or either Borrower applies for,
consents to, or acquiesces in the appointment of a trustee, receiver or other
custodian for the Borrower or any property thereof, or makes a general
assignment for the benefit of creditors; or, in the absence of such application,
consent or acquiescence, a trustee, receiver or other custodian is appointed for
either Borrower or for a substantial part of the property of any thereof and is
not discharged within 60 days; or any bankruptcy, reorganization, debt
arrangement, or other case or proceeding under any bankruptcy or insolvency law,
or any dissolution or liquidation proceeding, is commenced in respect of either
Borrower, and if such case or proceeding is not commenced by the Borrower, it is
consented to or acquiesced in by the Borrower, or remains for 30 days
undismissed; or either Borrower takes any action to authorize, or in furtherance
of, any of the foregoing.

              8.18.1.5 Non-Compliance with Loan Documents. Failure by the
Borrower to comply with or to perform any other Loan Document (and not
constituting an Event of Default under any other provision of this Section 9)
and continuance of such failure for 30 days or such reasonably longer period so
long as the Borrower has commenced appropriate curative action within such 30
day period and diligently pursues such action until such failure is cured.

              8.18.1.6 Warranties. Any warranty made by either Borrower herein
or any other Loan Document is breached or is false or misleading in any material
respect, or any schedule, certificate, financial statement, report, notice or
other writing furnished by the Borrower to the Bank or any Bank in connection
herewith is false or misleading in any material respect on the date as of which
the facts therein set forth are stated or certified.

Agreements and/or the Master Servicer terminates any of the Serving Agreements
for any reason.

              8.18.1.8 Judgments. Final judgments which exceed an aggregate of
$1,000,000.00 shall be rendered against the Borrower or any Subsidiary and shall
not have been paid, discharged or vacated or had execution thereof stayed
pending appeal within 30 days after entry or filing of such judgments.

              Invalidity of Collateral Documents, etc. The Security Agreement
shall cease to be in full force and effect; or the Borrower (or any Person by,
through or on behalf of the Borrower) shall contest in any manner the validity,
binding nature or enforceability of any Security Agreement.

              Material Adverse Effect. The occurrence of any event having a
Material Adverse Effect.

         8.2 Effect of Event of Default. If any Event of Default described in
Section 9.1.4 shall occur, the Commitment (if it has not theretofore terminated)
shall immediately terminate and the Loans and all other obligations hereunder
shall become immediately due and payable, all without presentment, demand,
protest or notice of any kind; and, if any other Event of Default shall occur
and be continuing, the Bank may declare the Commitment (if it has not
theretofore terminated) to be terminated and/or declare all Loans and all other
obligations hereunder to be due and payable, whereupon the Commitment (if it has
not theretofore terminated) shall immediately terminate and/or all Loans and all
other obligations hereunder shall become immediately due and payable, all
without presentment, demand, protest or notice of any kind. The Bank shall
promptly advise the Borrower of any such declaration, but failure to do so shall
not impair the effect of such declaration.

     SECTION 9   GENERAL.

         9.1 Waiver; Amendments. No delay on the part of the Bank in the
exercise of any right, power or remedy shall operate as a waiver thereof, nor
shall any single or partial exercise by any of them of any right, power or
remedy preclude other or further exercise thereof, or the exercise of any other
right, power or remedy. No amendment, modification or waiver of, or consent with
respect to, any provision of this Agreement or the Notes shall in any event be
effective unless the same shall be in writing and signed and delivered by the
Bank, and then any such amendment, modification, waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

Subsidiaries shall apply only during such times as the Borrower has one or more
Subsidiaries.

to contracts made and to be performed entirely within such State. Whenever
possible each provision of this Agreement shall be interpreted in such manner as

<PAGE>   27

limitation of those provided by applicable law.

each such counterpart shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Agreement.

Borrower and the Bank and their respective successors and assigns, and shall
inure to the benefit of the Borrower and the Bank and the successors and assigns

exonerate and hold the Bank and each of the officers, directors, employees,
Affiliates and agents of the Bank (each a "Bank Party") free and harmless from
and against any and all actions, causes of action, suits, losses, liabilities,
damages and expenses, including reasonable attorney costs (collectively, the

arising out of, or relating to (i) any transaction financed or proposed to be
financed in whole or in part, directly or indirectly, with the proceeds of any
of the Loans, (ii) the use, handling, release, emission, discharge,
transportation, storage, treatment or disposal of any hazardous substance at any

delivery, performance or enforcement of this Agreement or any other Loan
Document by any of the Bank Parties, except for any such Indemnified Liabilities
arising on account of the applicable Bank Party's gross negligence or willful
misconduct. If and to the extent that the foregoing undertaking may be
unenforceable for any reason, the Borrower hereby agrees to make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. All obligations provided
for in this Section 10.12 shall survive repayment of the Loans, cancellation of
the Notes, expiration or termination of the Letters of Credit, any foreclosure

Borrower's business or operations. The Borrower agrees that the Bank shall not
have liability to the Borrower (whether sounding in tort, contract or otherwise)
for losses suffered by the Borrower in connection with, arising out of, or in
any way related to the transactions contemplated and the relationship
established by the Loan Documents, or any act, omission or event occurring in
connection therewith, unless it is determined in a final non-appealable judgment
by a court of competent jurisdiction that such losses resulted from the gross
negligence or willful misconduct of the party from which recovery is sought. The
Bank shall not have any liability with respect to, and the Borrower hereby
waives, releases and agrees not to sue for, any special, indirect or
consequential damages suffered by the Borrower in connection with, arising out
of, or in any way related to the Loan Documents or the transactions contemplated
thereby.

         9.11 FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED

$10,000,000.00                                      Note No. ________________
                                                     Farmington Hills, Michigan

Due Date: March 30, 2001                            Dated: As of March 31, 2000

          FOR VALUE RECEIVED, on the Due Date, BINGHAM FINANCIAL SERVICES
CORPORATION, a Michigan corporation, and DYNEX FINANCIAL, INC., a Virginia
corporation, (individually and collectively the "Borrower"), severally, and
jointly and severally promise to pay to the order of MICHIGAN NATIONAL BANK, a
national banking association (the "Bank"), at its office set forth below or at
such other place as Bank may designate in writing, the principal sum of TEN
MILLION AND NO/100 DOLLARS ($10,000,000.00), or such lesser amount as may be
outstanding under the Credit Agreement of even date herewith between Borrower
and Bank (the "Credit Agreement"), plus interest as hereinafter provided, all in
lawful money of the United States of America as follows:

1.   The unpaid principal balance of this promissory note ("Note") shall bear
     interest computed upon the basis of a year of 360 days for the actual
     number of days elapsed in a month, at a per annum rate of interest (the
     "Effective Interest Rate") which is equal to 200 basis points (or, 2.00%)
     in excess of the Trailing Rate Average LIBOR (as hereafter defined). As
     used herein, "Trailing Rate Average LIBOR" means the 30-day trailing
     average daily London Interbank Offered Rate for one month U.S. Dollar
     denominated deposits offered by major banks in the London, United Kingdom,
     market at 11:00 a.m. London Time, as reported by one of the following
     sources, selected by Bank on an availability basis, in descending order of
     priority: (1) the Dow Jones Telerate System "LIBOR Page" report of such
     interest rates as determined by Reuter's News Service; (2) the Dow Jones
     Telerate System "Page 3750" report of such interest rates as determined by
     the British Bankers Association; or (3) The Wall Street Journal, Midwest
     Edition, report of such interest rate; or (4) any other generally accepted
     authoritative source as Bank may reference. The said 30-day trailing
     average will be updated by Bank each Business Day by adding the most
     recently reported London Interbank Offered Rate on one month U.S. Dollar
     deposits and by subtracting the oldest reported rate on said deposits.

                                      A-1

     This Note is executed and delivered pursuant to the Credit Agreement, the
terms of which are incorporated herein as if fully set forth herein, and all
capitalized terms not defined herein shall have the meaning ascribed to them in
the Credit Agreement.

     As provided in the Credit Agreement, the Borrower may make voluntary
prepayments hereon at any time and in some cases must make mandatory prepayments
hereon.

     Advances of principal, repayment, and readvances may be made under this
Note from time to time, but Bank, in its sole discretion, may refuse to make
advances or readvances hereunder during any period(s) this Note is in default.
All advances made hereunder shall be charged to a loan account in Borrower's
name on Bank's books, and Bank shall debit to such account the amount of each
advance made to, and credit to such account the amount of each repayment made by
Borrower. From time to time, Bank shall furnish Borrower a statement of
Borrower's loan account, which statement shall be deemed to be correct, accepted
by, and binding upon Borrower, unless Bank receives a written statement of
exceptions from Borrower within thirty (30) days after such statement has been
furnished.

     Upon the occurrence of any default or Event of Default and the expiration
of any applicable cure period as described in the Credit Agreement, this Note
and all other obligations and Indebtedness of Borrower to Bank (whether absolute
or contingent, direct or indirect, present or future, and howsoever evidenced)
at Bank's option, will immediately become due and payable, and all without
formal demand, presentment or notice of any kind, all of which are expressly
waived.

     Borrower shall not be required to pay interest at a rate greater than the
maximum allowed by law and any interest payment received by Bank which exceeds
the maximum legal rate, shall be automatically credited upon the unpaid
principal balance of the Note, or, if there is no principal then outstanding on
this Note, returned to Borrower.

     Upon the occurrence of any Event of Default as described in the Credit
Agreement, the unpaid principal balance of this Note shall bear interest at a
rate which is two percent (2%) greater than the Effective Interest Rate
otherwise applicable. If any payment under this Note is not paid within ten (10)
days after the date due, at the option of Bank a late charge of not more than
five cents ($.05) for each dollar of the installment past due may be charged by
Bank.

     Acceptance by Bank of any payment in an amount less than the amount then
due shall be deemed an acceptance on account only, and Bank's acceptance of any
such partial payment shall not constitute a waiver of Bank's right to receive
the entire amount due. Borrower does hereby jointly and severally waive
presentment for payment, demand, notice of non-payment, notice of protest or
protest of this Note, and Bank diligence in collection or bringing suit, and do
hereby consent to any and all extensions of time, renewals, waivers or
modifications as may be granted by Bank with respect to payment or any other
provisions of this Note, and to the release of any

                                      A-2

collateral or any part thereof, with or without substitution. The liability of
the Borrower under this Note shall be absolute and unconditional, without regard
to the liability of any other party. This Note shall be deemed to have been
executed in Michigan, and all rights and obligations hereunder shall be governed
by the laws of the State of Michigan.

     Reference is hereby made to the Credit Agreement for additional terms and
conditions relating to this Note.

                                                      Farmington Hills, Michigan

Due Date: March 30, 2001                             Dated: As of March 31, 2000

         FOR VALUE RECEIVED, on the Due Date, BINGHAM FINANCIAL SERVICES
CORPORATION, a Michigan corporation, and DYNEX FINANCIAL, INC., a Virginia
corporation, (individually and collectively the "Borrower"), severally, and
jointly and severally promise to pay to the order of MICHIGAN NATIONAL BANK, a
national banking association (the "Bank"), at its office set forth below or at
such other place as Bank may designate in writing, the principal sum of TEN
MILLION AND NO/100 DOLLARS ($10,000,000.00), or such lesser amount as may be
outstanding under the Credit Agreement of even date herewith between Borrower
and Bank (the "Credit Agreement"), plus interest as hereinafter provided, all in
lawful money of the United States of America as follows:

1.   The unpaid principal balance of this promissory note ("Note") shall bear
     interest computed upon the basis of a year of 360 days for the actual
     number of days elapsed in a month, at a per annum rate of interest (the
     "Effective Interest Rate") which is equal to 200 basis points (or, 2.00%)
     in excess of the Trailing Rate Average LIBOR (as hereafter defined). As
     used herein, "Trailing Rate Average LIBOR" means the 30-day trailing
     average daily London Interbank Offered Rate for one month U.S. Dollar
     denominated deposits offered by major banks in the London, United Kingdom,
     market at 11:00 a.m. London Time, as reported by one of the following
     sources, selected by Bank on an availability basis, in descending order of
     priority: (1) the Dow Jones Telerate System "LIBOR Page" report of such
     interest rates as determined by Reuter's News Service; (2) the Dow Jones
     Telerate System "Page 3750" report of such interest rates as determined by
     the British Bankers Association; or (3) The Wall Street Journal, Midwest
     Edition, report of such interest rate; or (4) any other generally accepted
     authoritative source as Bank may reference. The said 30-day trailing
     average will be updated by Bank each Business Day by adding the most
     recently reported London Interbank Offered Rate on one month U.S. Dollar
     deposits and by subtracting the oldest reported rate on said deposits.

         This Note is executed and delivered pursuant to the Credit Agreement,
the terms of which are incorporated herein as if fully set forth herein, and all
capitalized terms not defined herein shall have the meaning ascribed to them in
the Credit Agreement.

         As provided in the Credit Agreement, the Borrower may make voluntary
prepayments hereon at any time and in some cases must make mandatory prepayments
hereon.

         Advances of principal, repayment, and readvances may be made under this
Note from time to time, but Bank, in its sole discretion, may refuse to make
advances or readvances hereunder during any period(s) this Note is in default.
All advances made hereunder shall be charged to a loan account in Borrower's
name on Bank's books, and Bank shall debit to such account the amount of each
advance made to, and credit to such account the amount of each repayment made by
Borrower. From time to time, Bank shall furnish Borrower a statement of
Borrower's loan account, which statement shall be deemed to be correct, accepted
by, and binding upon Borrower, unless Bank receives a written statement of
exceptions from Borrower within thirty (30) days after such statement has been
furnished.

         Upon the occurrence of any default or Event of Default and the
expiration of any applicable cure period as described in the Credit Agreement,
this Note and all other obligations and Indebtedness of Borrower to Bank
(whether absolute or contingent, direct or indirect, present or future, and
howsoever evidenced) at Bank's option, will immediately become due and payable,
and all without formal demand, presentment or notice of any kind, all of which
are expressly waived.

         Borrower shall not be required to pay interest at a rate greater than
the maximum allowed by law and any interest payment received by Bank which
exceeds the maximum legal rate, shall be automatically credited upon the unpaid
principal balance of the Note, or, if there is no principal then outstanding on
this Note, returned to Borrower.

         Upon the occurrence of any Event of Default as described in the Credit
Agreement, the unpaid principal balance of this Note shall bear interest at a
rate which is two percent (2%) greater than the Effective Interest Rate
otherwise applicable. If any payment under this Note is not paid within ten (10)
days after the date due, at the option of Bank a late charge of not more than
five cents ($.05) for each dollar of the installment past due may be charged by
Bank.

         Acceptance by Bank of any payment in an amount less than the amount
then due shall be deemed an acceptance on account only, and Bank's acceptance of
any such partial payment shall not constitute a waiver of Bank's right to
receive the entire amount due. Borrower does hereby jointly and severally waive
presentment for payment, demand, notice of non-payment, notice of protest or
protest of this Note, and Bank diligence in collection or bringing suit, and do
hereby consent to any and all extensions of time, renewals, waivers or
modifications as may be granted by Bank with respect to payment or any other
provisions of this Note, and to the release of any

collateral or any part thereof, with or without substitution. The liability of
the Borrower under this Note shall be absolute and unconditional, without regard
to the liability of any other party. This Note shall be deemed to have been
executed in Michigan, and all rights and obligations hereunder shall be governed
by the laws of the State of Michigan.

         Reference is hereby made to the Credit Agreement for additional terms
and conditions relating to this Note.
