         hereof, upon compliance with the procedures set forth in this Section
         2.2 and in EXHIBIT "C" attached hereto and made a part hereof. Requests
         for Advances shall be initiated by the Company (i) by delivering to the
         Lender and its designee, by telecopy (with original to be sent
         immediately thereafter by overnight mail) a completed and signed
         request for an Advance (an "Advance Request") in the form of EXHIBIT
         "A" attached hereto and made a part hereof, or (ii) by using the
         electronic data transmission service provided by the Lender and its
         licensor, MBMS Incorporated, to transmit to the Lender a request for
         Advance ("Electronic Request"), which shall include all information
         required by EXHIBIT "A" through the Warehouse Management System
         software provided by the Lender and its licensor, MBMS Incorporated.
         The Lender shall have the right, on not less than three (3) Business
         Days' prior notice to the Company, to modify the Advance Request,
         Electronic Request, or any exhibits hereto to conform to current legal
         requirements or Lender practices, and, as so modified, said Advance
         Request, Electronic Request or exhibits shall be deemed a part hereof.
         In consideration of the Lender permitting the Company to make
         Electronic Requests for Advances utilizing the Warehouse Management
         System software or Advance Requests by telecopy, the Company covenants
         and agrees to assume liability for and to protect, indemnify and save
         the Lender harmless from, any and all liabilities, obligations,
         damages, penalties, claims, causes of action, costs, charges and
         expenses, including attorneys' fees and expenses of employees, which
         may be imposed, incurred by or asserted against the Lender by reason of
         any loss, damage or claim howsoever arising or incurred because of, out
         of or in connection with (i) any action of the Lender pursuant to
         Electronic Requests or Advance Requests by telecopy, (ii) the breach of
         any provisions of this Agreement by the Company, (iii) the transfer of
         funds pursuant to such Electronic Requests or Advance Requests by
         telecopy, or (iv) the Lender's honoring or failing to honor any
         Electronic Request or Advance Request by telecopy for any reason or no
         reason whatsoever. The Lender is entitled to rely upon and act upon
         Electronic Requests or Advance Requests by telecopy, and the Company
         shall be unconditionally and absolutely estopped from denying (x) the
         authenticity and validity of any such transaction so acted upon by the
         Lender once the Lender has advanced funds and has deposited or
         transferred such funds as requested in any such Electronic Request or
         Advance Request by telecopy, and (y) the Company's liability and
         responsibility therefor.



                                                                         Page 13

                  to the Lender or its designee the documents set forth in
                  Section 11 of EXHIBIT "C" hereto. In case of Collateral
                  financed through a Wet Settlement Advance, the Company shall
                  cause all Collateral Documents to be delivered to the Lender
                  or its designee within seven (7) Business Days after the date
                  of the Wet Settlement Advance relating thereto.

                           (3) Before funding, the Lender and its designee shall
                  have a reasonable time to examine such Advance Request and the
                  Collateral Documents to be delivered prior to such requested
                  Advance, as set forth in the applicable Exhibit hereto, and
                  may reject such of them as do not meet the requirements of
                  this Agreement or of the related Purchase Commitment. The
                  Advance Request and the Collateral Documents must be received

                  (a) Pledged Mortgages that are to be transferred to a pool
         custodian in connection with the issuance of Mortgage-backed
         Securities, shall be released from the Lender's security interest only
         against payment to the Lender of the amount due the Lender in
         connection with such Pledged Mortgages as determined in accordance with
         Section 3.5 of this Agreement or against the issuance of such

         priority, perfected security interest in such Mortgage-backed
         Securities and the proceeds thereof until payment due the Lender in
         respect of said Pledged Mortgages is made to the Lender.

                  (b) In the case of Mortgage-backed Securities created from
         Pledged Mortgages, the Lender shall have the exclusive right to the
         possession of the Mortgage-backed Securities or, if the Mortgage-backed
         Securities are not to be issued in certificated form, shall have the
         right to have the book entries for the Mortgage-backed Securities
         issued in the Lender's name or the name or names of its designees.
         Lender shall cause delivery of the Mortgage-backed Securities to be
         made to the Investor or the book entries registered in the name of the
         Investor or the Investor's designee only against payment therefor. The

         Company agrees upon request of the Lender, to execute and deliver to
         such other financial institutions the Company's written concurrence in
         any such standing arrangements.

         3.3 Delivery of Collateral Documents. The Lender or its designee
exclusively shall deliver Pledged Mortgages or Pledged Securities to (a) an
Investor that has issued a Purchase Commitment with respect thereto for its
examination and purchase, or (b) an Approved Custodian for purposes of
examination or delivery in connection with the issuance of Mortgage-backed
Securities. In such cases where the Lender must deliver documents to an Investor
or Approved Custodian, the Lender must receive signed shipping instructions (in
the form of EXHIBIT "D"



                                                                         Page 19

Day prior to the expiration of the appended Purchase Commitment, in addition to
any other documents listed in Section III of EXHIBIT "C" in respect of the
issuance of Mortgage-backed Securities. If shipping instructions are received by
Lender before 2:00 p.m. Houston, Texas time of any Business Day, Lender will
ship the documents together with the Bailee Letter (in form of EXHIBIT "K") to
the Investor or Approved Custodian on the same Business Day, otherwise Lender
will ship the documents the next Business Day following receipt of shipping
instructions. In any case in which an Advance has been made hereunder against
Pledged Mortgages, based on the existence of a Purchase Commitment covering such
Pledged Mortgages, the Company agrees that such Pledged Mortgages will not be
placed in any mortgage pool other than an Eligible Mortgage Pool, unless such
Pledged Mortgages have been redeemed from pledge as permitted hereunder or other
arrangements, satisfactory to the Lender in its sole discretion, have been made
for the redemption of such Pledged Mortgages from pledge hereunder. The Lender
may deliver any document relating to the Collateral to the Company for
correction or completion against a trust receipt in the form of EXHIBIT "E"
attached hereto executed by the Company. The Company hereby represents and
warrants to and agrees with the Lender that any request by the Company for
release of the Collateral consisting of or relating to Mortgage Loans to the
Company shall be solely for the purposes of correcting clerical or
non-substantial documentation problems in preparation for returning such
Collateral to the Lender for ultimate sale or exchange and the aggregate
Collateral Value of the Collateral released to the Company pursuant to this
Section 3.3 will not exceed $500,000.00; the Company shall request such release
in compliance with all of the terms and conditions of such release set forth
herein; and the Company will return to the Lender such documentation released to
the Company pursuant to this Section 3.3 within ten (10) calendar days after
such delivery.

         3.4 Delivery of Additional Collateral or Mandatory Prepayment. At any
time that the aggregate Collateral Value of the Collateral then pledged
hereunder is less than the aggregate amount of the Advances then outstanding
hereunder (the "Deficiency"), the Lender may request, and the Company shall
within two (2) Business Days after Notice by the Lender, either (a) deliver to
the Lender or its designee for pledge hereunder additional Mortgage Loans and/or
cash, in aggregate amounts sufficient to cover the Deficiency, or (b) repay the
Advances in an amount equal to the Deficiency.

         3.5 Right of Redemption from Pledge. So long as no Event of Default has
occurred, the Company may redeem a Mortgage Loan or, Mortgage-backed Security,
by notifying the Lender of its intention to redeem such Mortgage Loan or
Mortgage-backed Security, from pledge and by paying, or causing an Investor to
pay, to the Lender, for application to prepayment of the principal balance of
the Note, an amount (the "Redemption Amount") equal to the amount of the Advance
made with respect to or relating to such Mortgage Loan or Mortgage-backed
Security.

         3.6 Collection and Servicing Rights. So long as no Event of Default
shall have occurred, the Company shall be entitled to service and receive and
collect directly all sums payable to the Company in respect of the Collateral
other than proceeds of any Purchase Commitment or proceeds of the sale of any
Collateral. Following the occurrence of any Event of Default, the Lender or its
designee shall thereafter be entitled to service and receive and collect all
sums payable to the Company in respect of the Collateral, and in such case (a)
the Lender or its designee in its discretion



                                                                         Page 20

may, in its own name or in the name of the Company or otherwise, demand, sue
for, collect or receive any money or property at any time payable or receivable
on account of or in exchange for any of the Collateral, but shall be under no
obligation to do so, (b) the Company shall, if the Lender so requests, forthwith
pay to the Lender at its principal office all amounts thereafter received by the
Company upon or in respect of any of the Collateral, advising the Lender as to
the source of such funds, and (c) all amounts so received and collected by the
Lender shall be held by it as part of the Collateral.

         3.7 Return or Release of Collateral at End of Commitment. If (a) the
Commitment shall have expired or been terminated, and (b) no Advances, interest
or other Obligations evidenced by the Loan Documents or due under this Agreement
shall be outstanding and unpaid, the Lender shall deliver or release all
Collateral in its possession to the Company. The receipt of the Company for any
Collateral released or delivered to the Company pursuant to any provision of
this Agreement shall be a complete and full acquittance for the Collateral so
returned, and the Lender shall thereafter be discharged from any liability or
responsibility therefor.

        Obligations of the Company in any manner permitted by law or provided
        for hereunder.

               (2) Notify all obligors in respect of the Collateral that the
        Collateral has been assigned to the Lender and that all payments thereon
        are to be made directly to the Lender or such other party as may be
        designated by the Lender; settle, compromise, or release, in whole or in
        part, any amounts owing on the Collateral, any such obligor or any
        Investor or any portion of the Collateral, on terms acceptable to the
        Lender; enforce payment and prosecute any action or proceeding with
        respect to any and all Collateral; and where any such Collateral is in
        default, foreclose on and enforce security interests in, such Collateral
        by any available judicial procedure or without judicial process and sell
        property acquired as a result of any such foreclosure.

               (3) Act, or contract with a third party to act, as servicer or
        subservicer of each item of Collateral requiring servicing and perform
        all obligations required in connection with Purchase Commitments, such
        third party's fees to be paid by the Company.

               (4) Require the Company to assemble the Collateral and/or books
        and records relating thereto and make such available to the Lender at a
        place to be designated by the Lender.

               (5) Enter onto property where any Collateral or books and records
        relating thereto are located and take possession thereof with or without
        judicial process.
                                                                         Page 42
<PAGE>   48
            
               (6) Prior to the disposition of the Collateral, prepare it for
        disposition in any manner and to the extent the Lender deems
        appropriate.

               (7) Exercise all rights and remedies of a secured creditor under
        the Uniform Commercial Code of Texas or other applicable law, including,
        but not limited to, selling or otherwise disposing of the Collateral, or
        any part thereof, at one or more public or private sales, whether or not
        such Collateral is present at the place of sale, for cash or credit or
        future delivery, on such terms and in such manner as the Lender may
        determine, including, without limitation, sale pursuant to any
        applicable Purchase Commitment. If notice is required under such
        applicable law, the Lender will give the Company not less than ten (10)
        days' notice of any such public sale or of the date after which private
        sale may be held. The Company agrees that ten (10) days' notice shall
        be reasonable notice. The Lender may, without notice or publication,
        adjourn any public or private sale or cause the same to be adjourned
        from time to time by announcement at the time and place fixed for the
        sale, and such sale may be made at any time or place to which the same
        may be so adjourned. In case of any sale of all or any part of the
        Collateral on credit or for future delivery, the Collateral so sold may
        be retained by the Lender until the selling price is paid by the
        purchaser thereof, but the Lender shall not incur any liability in case
        of the failure of such purchaser to take up and pay for the Collateral
        so sold and, in case of any such failure, such Collateral may again be
        sold upon like notice. The Lender may, however, instead of exercising
        the power of sale herein conferred upon it, proceed by a suit or suits
        at law or in equity to collect all amounts due upon the Collateral or to
        foreclose the pledge and sell the Collateral or any portion thereof
        under a judgment or decree of a court or courts of competent
        jurisdiction, or both.

               (8) Proceed against the Company on the Note.

        (d) The Lender shall incur no liability as a result of the sale or other
disposition of the Collateral, or any part thereof, at any public or private
sale or disposition. The Company hereby waives (to the extent permitted by law)
any claims it may have against the Lender arising by reason of the fact that the
price at which the Collateral may have been sold at such private sale was less
than the price which might have been obtained at a public sale or was less than
the aggregate amount of the outstanding Advances and the unpaid interest accrued
thereon, even if the Lender accepts the first offer received and does not offer
the Collateral to more than one offeree and none of the actions described herein
shall render Lender's disposition of the Collateral in such a manner as
commercially unreasonable.

        (e) The Company specifically waives (to the extent permitted by law) any
equity or right of redemption, all rights of redemption, stay or appraisal which
the Company has or may have under any rule of law or statute now existing or
hereafter adopted, and any right to require the Lender to (1) proceed against
any Person, (2) proceed against or exhaust any of the Collateral or pursue its
rights and remedies as against the Collateral in any particular order, or (3)
pursue any other remedy in its power. The Lender shall not be required to take
any steps necessary to preserve any rights of the Company against holders of
mortgages prior

                                                                         Page 43
<PAGE>   49

        in lien to the Lien of any Mortgage included in the Collateral or to
        preserve rights against prior parties.

               (f) The Lender may, but shall not be obligated to, advance any
        sums or do any act or thing necessary to uphold and enforce the Lien and
        priority of, or the security intended to be afforded by, any Mortgage
        included in the Collateral, including, without limitation, payment of
        delinquent taxes or assessments and insurance premiums. All advances,
        charges, costs and expenses, including reasonable attorneys' fees and
        disbursements, incurred or paid by the Lender in exercising any right,
        power or remedy conferred by this Agreement, or in the enforcement
        hereof, together with interest thereon, at the Default Rate, from the
        time of payment until repaid, shall become a part of the principal
        balance outstanding hereunder and under the Note.

               (g) No failure on the part of the Lender to exercise, and no
        delay in exercising, any right, power or remedy provided hereunder, at
        law or in equity shall operate as a waiver thereof; nor shall any single
        or partial exercise by the Lender of any right, power or remedy provided
        hereunder, at law or in equity preclude any other or further exercise
        thereof or the exercise of any other right, power or remedy. Without
        intending to limit the foregoing, all defenses based on the statute of
        limitations are hereby waived by the Company to the extent permitted by
        law. The remedies herein provided are cumulative and are not exclusive
        of any remedies provided at law or in equity.

        8.3 Application of Proceeds. The proceeds of any sale, disposition or
other enforcement of the Lender's security interest in all or any part of the
Collateral shall be applied by the Lender:

                First, to the payment of the costs and expenses of such sale or
        enforcement, including reasonable compensation to the Lender's agents
        and counsel, and all expenses, liabilities and advances made or incurred
        by or on behalf of the Lender in connection therewith;

                Second, to the payment of any other amounts due (other than
        principal and interest) under the Note or this Agreement;

                Third, to the payment of interest accrued and unpaid on the
        Note; 
                Fourth, to the payment of the outstanding principal balance of
        the Note; and 

                Finally, to the payment to the Company, or to its successors or
        assigns, or as a court of competent jurisdiction may direct, of any 
        surplus then remaining from such proceeds.

        If the proceeds of any such sale, disposition or other enforcement are
insufficient to cover the costs and expenses of such sale, as aforesaid, and the
payment in full of all Obligations of the Company, the Company shall remain
liable for any deficiency.

        8.4 Lender Appointed Attorney-in-Fact. The Lender is hereby appointed
the attorney-in-fact of the Company, with full power of substitution, for the
purpose of carrying out the

                                                                         Page 44
<PAGE>   50

provisions hereof and taking any action and executing any instruments which the
Lender may deem necessary or advisable to accomplish the purposes hereof, which
appointment as attorney-in-fact is irrevocable and coupled with an interest.
Without limiting the generality of the foregoing, the Lender shall have the
right and power to give notices of its security interest in the Collateral to
any Person, either in the name of the Company or in its own name, to endorse all
Pledged Mortgages or Pledged Securities payable to the order of the Company, to
change or cause to be changed the book-entry registration or name of subscriber
or Investor on any Pledged Security, or to receive, endorse and collect all
checks made payable to the order of the Company representing any payment on
account of the principal of or interest on, or the proceeds of sale of, any of
the Pledged Mortgages or Pledged Securities and to give full discharge for the
same.

        8.5 Right of Set-Off. If the Company shall default in the payment of the
Note, any interest accrued thereon, or any other sums which may become payable
hereunder when due, or in the performance of any of its other Obligations under
this Agreement, the Lender, shall have the right, at any time and from time to
time, without notice, to set-off and to appropriate or apply any and all
property or indebtedness of any kind at any time held or owing by the Lender to
or for the credit of the account of the Company (excluding any monies held by
the Company in trust for third parties) against and on account of the
Obligations, irrespective of whether or not the Lender shall have made any
demand hereunder and whether or not said Obligations shall have matured;
provided, however, that the Lender shall not be allowed to set-off against funds
in accounts with respect to which (i) the Company is a trustee or an escrow
agent in respect of bona fide third parties other than Affiliates, and (ii) such
trust or escrow arrangement was so denominated at the time of the creation of
such account.

10.     REIMBURSEMENT OF EXPENSES; INDEMNITY.

        The Company shall: (a) pay all out-of-pocket costs and expenses of the
Lender, including, without limitation, reasonable attorneys' fees, in connection
with the preparation, negotiation, documentation, enforcement and administration
of this Agreement, the Note, and other Loan Documents and the making and
repayment of the Advances and the payment of interest thereon; provided, however
costs and expenses of Lender for attorneys fees in connection with the
preparation, negotiation and documentation of the lending transaction evidenced
by this Agreement shall not exceed $5,000.00 plus the reasonable expenses of
Lender's counsel; (b) pay, and hold the Lender and any holder of the Note
harmless from and against, any and all present and future stamp, documentary and
other similar taxes with respect to the foregoing matters and save the Lender
and the holder or holders of the Note harmless from and against any and all
liabilities with respect to or resulting from any delay or omission to pay such
taxes; (c) INDEMNIFY, PAY AND HOLD HARMLESS THE LENDER AND ANY OF ITS OFFICERS,
DIRECTORS, EMPLOYEES OR AGENTS AND ANY SUBSEQUENT HOLDER OF THE NOTE FROM AND
AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER (THE
"INDEMNIFIED LIABILITIES") (INCLUDING, WITHOUT LIMITATION, INDEMNIFIED
LIABILITIES RESULTING, IN WHOLE OR IN PART, FROM LENDER'S OWN NEGLIGENCE OR
STRICT LIABILITY) WHICH MAY BE IMPOSED UPON, INCURRED BY OR ASSERTED AGAINST THE
LENDER OR SUCH HOLDER IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT,
THE NOTE, OR ANY OTHER LOAN DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY TO THE EXTENT THAT ANY SUCH INDEMNIFIED LIABILITIES RESULT
(DIRECTLY OR INDIRECTLY) FROM ANY CLAIMS MADE, OR ANY ACTIONS, SUITS OR
PROCEEDINGS COMMENCED OR THREATENED, BY OR ON BEHALF OF ANY CREDITOR (EXCLUDING
THE LENDER AND THE

                                                                         Page 46

HOLDER, OR HOLDERS OF THE NOTE), SECURITY HOLDER, SHAREHOLDER, CUSTOMER
(INCLUDING, WITHOUT LIMITATION, ANY PERSON HAVING ANY DEALINGS OF ANY KIND WITH
THE COMPANY), TRUSTEE, DIRECTOR, OFFICER, EMPLOYEE AND/OR AGENT OF THE COMPANY
ACTING IN SUCH CAPACITY, THE COMPANY OR ANY GOVERNMENTAL REGULATORY BODY OR
AUTHORITY. THE FOREGOING INDEMNITY SHALL NOT APPLY TO THE EXTENT THE INDEMNIFIED
LIABILITIES RESULT FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE LENDER
OR LENDER'S OWN VIOLATIONS OF REGULATIONS APPLICABLE TO IT. THE AGREEMENT OF THE
COMPANY CONTAINED IN THIS SUBSECTION (C) SHALL SURVIVE THE EXPIRATION OR
TERMINATION OF THIS AGREEMENT AND THE PAYMENT IN FULL OF THE NOTE. ATTORNEYS'
FEES AND DISBURSEMENTS INCURRED IN ENFORCING, OR ON APPEAL FROM, A JUDGMENT
PURSUANT HERETO SHALL BE RECOVERABLE SEPARATELY FROM AND IN ADDITION TO ANY
OTHER AMOUNT INCLUDED IN SUCH JUDGMENT, AND THIS CLAUSE IS INTENDED TO BE
SEVERABLE FROM THE OTHER PROVISIONS OF THIS AGREEMENT AND TO SURVIVE AND NOT BE
MERGED INTO SUCH JUDGMENT.

11.     FINANCIAL INFORMATION.

        All financial statements and reports furnished to the Lender hereunder
shall be prepared in accordance with GAAP, applied on a basis consistent with
that applied in preparing the financial statements as at, and for the period
ended, the Statement Date (except to the extent otherwise required to conform to
good accounting practice).

12.     MISCELLANEOUS.

        12.1 Terms Binding Upon Successors; Survival of Representations. The
terms and provisions of this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns. All
representations, warranties; covenants and agreements herein contained on the
part of the Company shall survive the making of any Advance and the execution of
the Note, and shall be effective so long as the Commitment is outstanding
hereunder or there remain any Obligations of the Company hereunder or under the
Note to be paid or performed.

        12.2 Assignment. This Agreement may not be assigned by the Company. The
Lender may assign, at any time, in whole or in part, its rights and delegate its
obligations under this Agreement and the other Loan Documents, along with the
Lender's security interest in any or all of the Collateral, and any assignee
thereof may enforce this Agreement and the other Loan Documents, and such
security interest.

        12.3 Amendments. Except as otherwise provided in this Agreement, this
Agreement may not be amended, modified or supplemented unless such amendment,
modification or supplement is set forth in a writing signed by the parties
hereto.



                                                                         Page 47
<PAGE>   53

        12.4 Governing Law. This Agreement and the other Loan Documents shall be
governed by the laws of the State of Texas, without reference to its principles
of conflicts of laws.

        12.5 Participations. The Lender may at any time sell, assign or grant
participations in, or otherwise transfer to any other Person (a "Participant"),
all or part of the Obligations of the Company under this Agreement. Without
limitation of the exclusive right of the Lender to collect and enforce such
Obligations, the Company agrees that each disposition will give rise to a
debtor-creditor relationship of the Company to the Participant, and the Company
authorizes each Participant, upon the occurrence of an Event of Default, to
proceed directly by right of setoff, banker's lien, or otherwise, against any
assets of the Company which may be in the hands of such Participant. The Company
authorizes the Lender to disclose to any prospective Participant and any
Participant any and all information in the Lender's possession concerning the
Company, this Agreement and the Collateral.

        12.6 Relationship of the Parties. This Agreement provides for the making
of Advances by the Lender, in its capacity as a lender, to the Company, in its
capacity as a borrower, and for the payment of interest, repayment of principal
by the Company to the Lender, and for the payment of certain fees by the Company
to the Lender. The relationship between the Lender and the Company is limited to
that of creditor/secured party, on the one hand, and debtor, on the other hand.
The provisions herein for compliance with financial covenants and delivery of
financial statements are intended solely for the benefit of the Lender to
protect its interests as lender in assuring payments of interest and repayment
of principal and payment of certain fees, and nothing contained in this
Agreement shall be construed as permitting or obligating the Lender to act as a
financial or business advisor or consultant to the Company, as permitting or
obligating the Lender to control the Company or to conduct the Company's
operations, as creating any fiduciary obligation on the part of the Lender to
the Company, or as creating any joint venture, agency, or other relationship
between the parties hereto other than as explicitly and specifically stated in
this Agreement. The Company acknowledges that it has had the opportunity to
obtain the advice of experienced counsel of its own choosing in connection with
the negotiation and execution of this Agreement and to obtain the advice of such
counsel with respect to all matters contained herein, including, without
limitation, the provision for waiver of trial by jury. The Company further
acknowledges that it is experienced with respect to financial and credit matters
and has made its own independent decisions to apply to the Lender for credit and
to execute and deliver this Agreement.

        12.7 Severability. If any provision of this Agreement shall be declared
to be illegal or unenforceable in any respect, such illegal or unenforceable
provision shall be and become absolutely null and void and of no force and
effect as though such provision were not in fact set forth herein, but all other
covenants, terms, conditions and provisions hereof shall nevertheless continue
to be valid and enforceable.

        12.8 Usury. It is the intent of Lender and the Company in the execution
and performance of this Agreement and the Note or any Loan Document to remain in
strict compliance with Applicable Law from time to time in effect. In
furtherance thereof, Lender and the Company stipulate and agree that none of the
terms and provisions contained in the Note, this Agreement or any Loan Document
shall ever be construed to create a contract to pay for the use, forbearance or

                                                                         Page 48
<PAGE>   54

detention of money with interest at a rate or in an amount in excess of the
Maximum Rate or amount of interest permitted to be charged under Applicable Law.
For purposes of this Agreement, the Note and any other Loan Document, "interest"
shall include the aggregate of all charges which constitute interest under
Applicable Law that are contracted for, taken, charged, reserved, or received
under this Agreement, the Note or any other Loan Document. The Company shall
never be required to pay unearned interest or interest at a rate or in an amount
in excess of the Maximum Rate or amount of interest that may be lawfully charged
under Applicable Law, and the provisions of this paragraph shall control over
all other provisions of this Agreement and the Note or any Loan Document, which
may be in actual or apparent conflict herewith. If the Note is prepaid, or if
the maturity of the Note is accelerated for any reason, or if under any other
contingency the effective rate or amount of interest which would otherwise be
payable under the Note would exceed the Maximum Rate or amount of interest
Lender or any other holder of the Note is allowed by Applicable Law to charge,
contract for, take, reserve or receive, or in the event Lender or any holder of
the Note shall charge, contract for, take, reserve or receive monies that are
deemed to constitute interest which would, in the absence of this provision,
increase the effective rate or amount of interest payable under the Note to a
rate or amount in excess of that permitted to be charged, contracted for, taken,
reserved or received under Applicable Law then in effect, then the principal
amount of the Note or the amount of interest which would otherwise be payable
under the Note or both shall be reduced to the amount allowed under Applicable
Law as now or hereinafter construed by the courts having jurisdiction, and all
such moneys so charged, contracted for, taken, reserved or received that are
deemed to constitute interest in excess of the Maximum Rate or amount of
interest permitted by Applicable Law shall immediately be returned to or
credited to the account of the Company upon such determination. Lender and the
Company further stipulate and agree that, without limitation of the foregoing,
all calculations of the rate or amount of interest contracted for, charged,
taken, reserved or received under the Note which are made for the purpose of
determining whether such rate or amount exceeds the Maximum Rate, shall be made
to the extent not prohibited by Applicable Law, by amortizing, prorating,
allocating and spreading during the period of the full stated term of the Note,
all interest at any time contracted for, charged, taken, reserved or received
from the Company or otherwise by Lender or any other holder of the Note.

        12.9 CONSENT TO JURISDICTION. SUBJECT TO THE PROVISIONS OF SECTION 12.9
OF THIS AGREEMENT, THE COMPANY HEREBY AGREES THAT ANY ACTION OR PROCEEDING UNDER
THIS AGREEMENT, THE NOTE OR ANY DOCUMENT DELIVERED PURSUANT HERETO MAY BE
COMMENCED AGAINST IT IN ANY COURT OF COMPETENT JURISDICTION WITHIN THE STATE OF
TEXAS, BY SERVICE OF PROCESS UPON THE COMPANY BY FIRST CLASS REGISTERED OR
CERTIFIED MAIL, RETURN RECEIPT REQUESTED, ADDRESSED TO THE COMPANY AT ITS
ADDRESS LAST KNOWN TO THE LENDER. THE COMPANY AGREES THAT ANY SUCH SUIT, ACTION
OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER SUCH
DOCUMENT MAY BE INSTITUTED IN HARRIS COUNTY, STATE DISTRICT COURT OR IN THE
UNITED STATES DISTRICT COURT FOR THE DISTRICT OF TEXAS AT THE OPTION OF THE
LENDER; AND THE COMPANY HEREBY WAIVES ANY OBJECTION TO THE VENUE, OR ANY CLAIM
AS TO INCONVENIENT FORUM, OF ANY SUCH SUIT, ACTION OR PROCEEDING. NOTHING HEREIN
SHALL AFFECT THE RIGHT OF THE LENDER TO ACCOMPLISH SERVICE OF PROCESS IN ANY
OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE
PROCEED AGAINST THE COMPANY IN ANY OTHER JURISDICTION OR COURT.



                                                                         Page 49

        12.10 Arbitration. To the maximum extent not prohibited by law, any
controversy, dispute or claim arising out of, in connection with, or relating to
the Commitment or the Loan Documents or any transaction provided for therein,
including but not limited to any claim based on or arising from an alleged tort
or an alleged breach of any agreement contained in any of the Loan Documents,
shall, at the request of any party to the Loan Documents (either before or after
the commencement of judicial proceedings), be settled by arbitration pursuant to
Title 9 of the United States Code, which the parties hereto acknowledge and
agree applies to the transaction involved herein, and in accordance with the
Commercial Arbitration Rules of the American Arbitration Association (the
"AAA"). If Title 9 of the United States Code is inapplicable to any such claim,
dispute or controversy for any reason, such arbitration shall be conducted
pursuant to the Texas General Arbitration Act and in accordance with the
Commercial Arbitration Rules of the AAA. In any such arbitration proceeding: (i)
all statutes of limitations which would otherwise be applicable shall apply; and
(ii) the proceeding shall be conducted in Houston, Texas, by a single
arbitrator, if the amount in controversy is $1,000,000.00 or less, or by a
panel of three arbitrators if the amount in controversy is over $1,000,000.00.
All arbitrators shall be selected by the process of appointment from a panel
pursuant to Section 13 of the AAA Commercial Arbitration Rules and each
arbitrator shall be either an active attorney, a mortgage banker or retired
judge with an AAA acknowledged expertise in the subject matter of the
controversy, dispute or claim. Any award rendered in any such arbitration
proceeding shall be final and binding, and judgment upon any such award may be
entered in any court having jurisdiction.

      If any party to any Loan Document files a proceeding in any court to
resolve any such controversy, dispute or claim, such action shall not constitute
a waiver of the right of such party or a bar to the right of any other party to
seek arbitration under the provisions of this Section of that or any other
claim, dispute or controversy, and the court shall, upon motion of any party to
the proceeding, direct that such controversy, dispute or claim be arbitrated in
accordance with this Section.

      Notwithstanding any of the foregoing, the parties hereto agree that no
arbitrator or panel of arbitrators shall possess or have the power to (i) assess
punitive damages, (ii) dissolve, rescind or reform (except that the arbitrator
may construe ambiguous terms) any Loan Document, (iii) enter judgment on the
debt, (iv) exercise equitable powers or issue or enter any equitable remedies
with respect to matters submitted to arbitration, or (v) allow discovery of
attorney/client privileged information. The Commercial Arbitration Rules of the
AAA are hereby modified to this extent for the purpose of arbitration of any
dispute, controversy or claim arising out of, in connection with, or relating to
the Loan or any Loan Document. The parties hereby further agree to waive, each
to the other, any claims for punitive damages and agree neither an arbitrator
nor any court shall have the power to assess such damages.

      No provision of, or the exercise of any rights under, this Section shall
limit or impair the right of any party to any Loan Document before, during or
after any arbitration proceeding to: (i) exercise self-help remedies such as
setoff or repossession; (ii) foreclose (judicially or otherwise) any Lien on or
security interest in any real or personal Collateral; or (iii) obtain emergency
relief from a court of competent jurisdiction to prevent the dissipation,
damage, destruction, transfer, hypothecation, pledging or concealment of assets
or of Collateral securing any Indebtedness, obligation or guaranty

                                                                         Page 50

referenced in any Loan Document. Such emergency relief may be in the nature of,
but is not limited to: pre-judgment attachments, garnishments, sequestrations,
appointments of receivers, or other emergency injunctive relief to preserve the
status quo.

        12.11 ADDITIONAL INDEMNITY. IN ADDITION TO THE INDEMNITY PROVIDED IN

        GARCIA (BNC BORROWER), BNC, ADV. FIRST UNION MORTGAGE CORPORATION -
FLORIDA CIRCUIT COURT CASE NO. 98-01621C

        Attorney Representation: BNC Counsel Catherine Hanan monitoring Title
Company Appointed Counsel in Florida
 
        Type of Matter: Foreclosure of Senior Lien - BNC not true party in
interest.

        Matter initiated in March of 1998 to foreclose a senior lien in the
amount of $700.00 not fully paid off when BNC closed its loan. That amount was
the short fall to a lender which should have been paid by the title
company/escrow at the BNC loan closing on this refinance.

        Summary of Response: Title company is defending the matter on behalf of
BNC at no cost BNC. In the event Plaintiff is successful, the title company
would have to pay off the senior lien amount to avoid foreclosure of the BNC
originated loan per the terms of the title policy. Title company counsel
successfully defeated a summary judgment motion brought against BNC and as of
August 20, 1998 and advised that settlement discussions were underway with
Plaintiff. Apparently, the amount in question which the title company is
negotiating about, has increased dramatically from the $700.00 shortfall,
because of foreclosure costs, attorney fees and other claims. The matter has not
yet settled because the Plaintiff's claim is now inflated to somewhere around
$9,500.00 which the title company feels is unconscionable. In any event,
resolution of the matter and dismissal of BNC as a defendant seems likely in the
near future.

CALIFORNIA (SAN DIEGO)

        Attorney Representation: BNC Counsel Catherine Hanan and In House
Attorney for First American Title Company in San Diego.

        Type of Matter: Forfeiture action by government against borrower on the
basis of criminal, drug related activity in which government seeks to foreclose
on forfeiture lien and has named BNC's $98,600.00 first lien as a lien which
would be junior to the forfeiture action. BNC has tendered a defense of the
matter to First American which has agreed to act solely to obtain documentation
from the government to the effect that the lien originated by BNC Mortgage, Inc.
is valid and superior to the government foreclosure action and any foreclosure
is subject to the BNC loan. BNC has requested dismissal as a named party
inasmuch as it no longer is the true party in interest under the loan and has
notified the investor of the matter. BNC is awaiting paperwork to be provided
through the title company.

        BNC MORTGAGE INC. V. FLEET MORTGAGE CORP. AND MARCHETTI, SUPERIOR COURT
OF RHODE ISLAND

        ATTORNEY REPRESENTATION: TITLE COMPANY APPOINTED COUNSEL FOR BNC
PATRICIA A. BUCKLEY IN PROVIDENCE RHODE ISLAND AND CATHERINE HANAN MONITORING

        TYPE OF MATTER: Title Claim for Missed Senior Lien. BNC received notice
that Fleet Mortgage Corporation was foreclosing a lien which was claimed to be
superior to the BNC originated lien.

        SUMMARY OF RESPONSE: The title company engaged counsel to file suit to
quiet title regarding the BNC mortgage and to enjoin the foreclosure sale. The
temporary restraining order against Fleet stopping the foreclosure granted on
October 27, 1998 will remain in effective at least until January 22, 1999 which
is the continued hearing date on the permanent injunction. In the event of an
adverse determination as to BNC's lien, the title company will be forced to
compensate BNC or its investor in connection with damages ultimately caused by
the senior lien and its foreclosure.

        ROY DOWNS V. BARBARA DOWNS THOMPSON, BNC, et, al. - SUPERIOR COURT OF
THE DISTRICT OF COLUMBIA - CASE NO. 98-01621CA25

        Attorney Representation: BNC Counsel Catherine Hanan monitors Outside
Counsel Appointed By Title Insurer

        Type of Matter: Complaint to Quiet Title on Real Property and for Fraud
regarding BNC Loan Plaintiff Downs filed suit in May of 1998 contending that his
daughter and third parties conspired to obtain the $172,900.00 BNC loan without
his knowledge, using forged loan documents are forgeries such that the BNC loan
is fraudulent and therefore void.

        Summary of Response: BNC tendered defense of the litigation to the title
company which also served as the escrow. The title company is defending the case
at no cost to BNC, AND HAS PROVIDED TARDY NOTICE THAT THE DEFENSE IS PROVIDED
UNDER A RESERVATION OF RIGHTS LEST EVIDENCE BE UNCOVERED THAT BNC KNOWINGLY
PARTICIPATED IN THE FORGERY AND FRAUD. NO SUCH EVIDENCE HAS BEEN UNCOVERED, AND
ALL SIGNS POINT TO THE FATHER AND DAUGHTER CONCOCTING THE STORY TO AVOID PAYING
THE MORTGAGE. Discovery is continuing and the title company has agreed to
provide a courtesy defense to BNC's interim servicer, Option One Mortgage
Corporation. In the event Plaintiff is successful, the title company would have
the obligation to pay the policy limits in connection with the loan, which sums
would be tendered to BNC's investor. PLAINTIFF SUCCESS IS UNLIKELY IN VIEW OF
HANDWRITING EXPERT TESTIMONY THAT ALL DOCUMENTS WERE EXECUTED BY PLAINTIFF.
PLAINTIFF'S ATTORNEY IS ATTEMPTING TO WITHDRAW FROM THE CASE, THE DAUGHTER IS
ALREADY IN PRO PER AND A TRIAL DATE SHOULD BE SET IN THE FUTURE.

Foreclosure and for Damages for Unjust Enrichment

        Summary of Response: IMC foreclosed on November 12th. First American as
well as a third party bid at the sale such that IMC's loan obligation was
satisfied and paid. The third party was the higher bidder. THE TITLE COMPANY HAD
EARLIER CONFIRMED THAT IT HAD REQUESTED DISMISSAL OF 1MC AND BNC FROM THE
LITIGATION INASMUCH AS THEY HAVE NO FURTHER INTEREST IN THE PROPERTY. THE
PLAINTIFF HAS NOT DISMISSED. THE TITLE COMPANY HAS ALREADY CONFIRMED THAT IT
WOULD DEFEND BNC AND IMC IN THE EVENT THE LITIGATION CONTINUED AND THIS OFFICE
HAS REMINDED THE TITLE COMPANY OF THAT OBLIGATION DUE TO A RECENT NOTICED
HEARING ON DEFAULT OF UNNAMED PARTY DEFENDANTS. WE WILL CONTINUE TO MONITOR THE
LITIGATION TO INSURE THAT NO MONETARY JUDGMENT IS ENTERED AGAINST BNC OR ITS
INVESTOR NOW THAT THE INVESTOR HAS BEEN PAID OFF THROUGH THE FORECLOSURE
PROCEEDINGS.

BNC MORTGAGE INC. V. FLEET MORTGAGE CORP. AND MARCHETTI. SUPERIOR COURT OF RHODE
ISLAND
CONTINUED

        FLEET FILED PLEADINGS IN WHICH IT MAINTAINS THAT IT HOLDS A VALID SENIOR
LIEN-AND THAT BNC's LIEN IS INVALID DUE TO THE TITLE INSURANCE COMPANY BEING
AWARE OF THE SENIOR LIEN PRIOR TO THE BNC LOAN TRANSACTION, AND SUCH AWARENESS
BEING IMPUTED TO ITS INSURED BECAUSE THE TITLE COMPANY AGREED TO ISSUE TITLE
INSURANCE WITHOUT ACKNOWLEDGING THE LIEN. IF SUCCESSFUL FLEET'S LIEN WOULD BE
INVALIDATED OR VOID BECAUSE BNC WOULD NO LONGER BE A BONIFIED LENDER. THE
BORROWER IS EXPECTED TO BECOME MORE INVOLVED IN THE LITIGATION AS WELL IN THE
NEAR FUTURE. SUBPOENAS HAVE BEEN ISSUED BY OUR ATTORNEY IN ORDER TO DETERMINE
WHAT, IF ANY DOCUMENTATION, FLEET HAS TO SUPPORT ITS POSITION. BUT IT APPEARS
THAT AT SOME POINT PRIOR TO THE BNC LOAN, THE TITLE COMPANY DID ATTEMPT TO BUY
THE FLEET LOAN. THERE WOULD ONLY BE ONE REASON FOR THE TITLE COMPANY TO DO THIS,
BECAUSE IT HAD A PRIOR CLAIM AND SOMEHOW KNEW THAT THE FLEET LIEN WAS VALID.
THEREFORE, FLEET'S CASE MAY BE VALID AND IT MAY HAVE A PROPER SENIOR LIEN.

        FLEET HAS PROPOSED A PARTIAL SETTLEMENT OF THE MATTER WHEREBY BNC'S LIEN
IS RECOGNIZED AS A VALID FIRST LIEN. BNC IS PUSHING FOR A GLOBAL RESOLUTION,
INCLUDING RECOGNITION OF ITS RIGHT TO A FIRST LIEN AND LITIGATION MAY BE
SUSPENDED WHILE THESE SETTLEMENT ALTERNATIVES ARE EXPLORED.

O'CONNOR V. BNC MORTGAGE - HAWAII SUPERIOR COURT

        Attorney Representation: BNC Counsel Neil O'Hanlon of Troop, Meisenger,
et al. and Local Hawaii Counsel Steven Chung of Oshima, Chun, Fong & Chung.

        Type of Matter: Complaint alleges BNC Violations of the Truth in Lending
Act at Loan Origination.

        Summary of Response: Matter commenced in early 1998 with discovery now
underway. Plaintiff's offer to settle was rejected by BNC which has filed a
motion for summary judgment which may dispose of the matter in favor of BNC in
the near future.


SCHMIDT V. BNC MORTGAGE, INC. - HAWAII SUPERIOR COURT

        Attorney Representation: BNC Counsel Catherine Hanan monitors Local
Hawaii Counsel Steven Chung of Oshima, Chun, Fong & Chung

        Type of Matter: Third Party Cross-Claim brought by borrower in April of
1998 against BNC to delay a judicial foreclosure being pursued by BNC's investor
against borrower for his failure to pay mortgage. Borrower alleges loan should
not have closed due to forgery and fraud and that lien which investor seeks to
foreclose is void.

      Summary of Response: Local Hawaii counsel is defending BNC against the
allegations and investigating whether title company has improperly refused to
defend. Preliminary investigation suggests that title company was instructed by
borrower not to close loan, but closed the loan anyway and title company may
have misapplied or misappropriated the loan proceeds.

      Schmidt, BNC and BNC's investor as the foreclosing lender are in
settlement discussions which include early dismissal of BNC as a defendant from
the proceedings. At present, and while settlement discussions continue, Schmidt
has agreed to suspend BNC's need to respond to the claims or otherwise defend in
the litigation.

        Attorney Representation: BNC Counsel, Neil O'Hanlon, Troop, Steuber,

        Type of Matter: The amended complaint alleges: fraud or deceit;
constructive fraud; undue influence; breach of covenant of good faith and fair
dealing; breach of fiduciary duty; breach of contract; unlawful business
practices; and negligent misrepresentation. Plaintiff seeks, in part,
restitution, injunctive relief for damages suffered and punitive damages.

        Summary of Response: Amended Complaint recently served upon BNC, counsel
retained and reviewing the matter. By way of background, in August of 1996, BNC
responded in writing to correspondence from Plaintiff's counsel advising that
after a review of all loan documentation, the loan was properly made, however
BNC was willing to further discuss the matter given the borrower's
dissatisfaction. No further contact or correspondence was received from the
borrower's counsel until service of the cross-complaint in January 1999.

ANGELES, CENTRAL DISTRICT - CASE NO. BC203559

        Attorney Representation: BNC Counsel, Glenn Lerman of Lerman & Brown

        Type of Matter: Plaintiff, an at will employee of BNC, was terminated
after three (3) months. Her response to the termination was to file suit
alleging that she was terminated for refusing to illegally solicit loans in the
state of Nevada. The Complaint alleges that BNC is liable for the commission of
a Public Policy Tort Termination; Intentional Infliction of Emotional Distress;
Labor Code Violations; Breach of Contract; Fraud and Concealment; Trade Slander;
violation of Business and Professions Codes 17,200, 17500 et seq. The Complaint
was served in January of 1999, and names BNC, as well as three individual
employees, including Evan Buckley.

        Summary of Response: BNC's counsel will remove the matter to Federal
Court after which BNC will vigorously defend the complaint. BNC has already
obtained an opinion letter from the Nevada State Commissioner of Financial
Institutions outlining that the lending activities (wholesale) in which BNC
participated in the state of Nevada, are permitted.

        CITY OF CHICAGO V. LA??? VIEW CULTURAL CENTER, MARGARET CROSS, BNC
MORTGAGE. INC.

        Attorney Representation: BNC Counsel Catherine Hanan with Possibility of
Local Counsel in Chicago to be Appointed

        Type of Matter: City of Chicago Quasi-Criminal Proceeding to Force
Rehabilitation of Dilapidated Property and/or Demolition of such Property

        Summary of Response: BNC's original investor did not record the
assignment provided at the loan sale such that BNC was served with all required
statutory notices by the prosecutors office relating to abandonment of the
property, required rehabilitation and/or demolition for the safety of the
public. BNC provided the prosecutor with information regarding the true party
investor as well as notifying its investor of the litigation AND THE PROSECUTOR
ADDED IMC TO THE SERVICE LIST SUCH THAT DIRECT NOTICE OF ALL PROCEEDINGS IS
BEING GIVEN TO BNC'S INVESTOR AS WELL AS BNC. BNC need not continue to monitor
the matter inasmuch no basis exists upon which a money judgment can be imposed
upon BNC which has no interest in the property. THE MATTER WILL BE MONITORED BUT
DELETED FROM THE LITIGATION LOG.

                                 OPINION LETTER

                                February 2, 1999

Bank United
3200 Southwest Freeway
Suite 1300
Houston, Texas 77027

        Re:     Warehousing Credit and Security Agreement (Single-Family
                Mortgage Loans) Gentlemen:

      We have acted as special counsel for BNC MORTGAGE, INC., a Delaware
corporation (the "Company"), in connection with the negotiation and execution of
the following documents (collectively, the "Credit Documents"):

        1.      the Warehousing Credit and Security Agreement (Single-Family
                Mortgage Loans) dated effective as of February 2, 1999 (the
                "Loan Agreement"), between the Company and Bank United (the
                "Lender"); and

        2.      the Note dated effective as of February 2, 1999 (the "Note"),
                executed and delivered by the Company.

      Unless otherwise provided herein, terms used herein which are defined in
the Credit Documents (including schedules and exhibits thereto) and not defined
herein shall have the meanings attributed thereto in the Credit Documents.

        1.      BASIS OF OPINION.

      As the basis for the conclusions expressed in this opinion letter, we have
examined, considered and relied upon the following:

               (1) A copy of each of the Credit Documents executed by the
Company;

               (2) A Recent Certificate of Domestic Status of the Company issued
by the Secretary of State of Delaware;

               (3) A copy of the Articles of Incorporation and amendments
thereto, and a copy of the Bylaws of the Company, in each case as certified to
us by the Company Certificate;

               (4) Such other documents and records as we have deemed relevant,
necessary or appropriate in connection with or as a basis for the opinions
hereafter set forth; and


                                  EXHIBIT "M"                            Page 75
<PAGE>   97

             (5) Such matters of law as we have considered necessary or
appropriate for the expression of the opinions contained herein.

        For the purposes of this opinion letter, the documents and information
referred to in this Section A are herein collectively referred to as the
"Documents".

        2. OPINIONS.

        Based upon our examination and consideration of the foregoing Documents,
and subject to the comments, assumptions, exceptions, qualifications and
limitations set forth in Section C below, we are of the opinion that:

               (1) The Company (i) is a corporation duly organized, validly
existing, and in good standing under the laws of the State of Delaware (ii) has
the full legal power and authority and all necessary licenses, permits,
franchises, and other authorizations to own and operate its property and assets
and to transact the business in which it is engaged, and (iii) is duly qualified
to transact business as a foreign corporation in each jurisdiction where the
nature of the business it transacts or the property it owns requires such
qualification or licensing except in such jurisdictions where the failure to be
in good standing or be licensed (as the case may be) would have no material
adverse effect on the Company.

               (2) The Company has the requisite corporate power to execute,
deliver, and perform the terms and provisions of each of the Credit Documents
and has taken all necessary corporate action to authorize the execution,
delivery, and performance by it of each such Credit Document. The Company has
duly executed each of the Credit Documents, and each such Credit Document
constitutes its legal, valid, and binding obligation enforceable in accordance
with its terms, except as the enforceability of the rights and remedies of the
Lender under each of the Credit Documents may be limited by applicable
bankruptcy, insolvency, reorganization or other similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(regardless of whether the issue of enforceability is considered in a proceeding
in equity or at law) including requirements of reasonableness and good faith in
the exercise of rights and remedies under the Credit Documents.

               (3) Neither the execution, delivery, or performance by the
Company of the Credit Documents, nor compliance by it with the terms and
provisions thereof, (i) will contravene any law, statute, rule, or regulation;
(ii) to the best of our knowledge, will contravene any order, writ, injunction,
or decree of any court or governmental instrumentality; (iii) to the best of our
knowledge, will conflict or be inconsistent with or result in any breach of any
of the material terms, covenants, conditions, or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any lien upon any of the property or assets of the Company
pursuant to the terms of any agreement of the Company; (iv) will violate any
provision of the Articles of Incorporation or Bylaws of the Company.

               (4) No order, consent, approval, license, authorization or
validation of, or filing, recording or registration with, or exemption by, any
governmental or public body or authority, or any subdivision thereof, is
required to authorize, or is required in connection with, (i) the execution,


                              EXHIBIT "M"                               Page 76
                                         
<PAGE>   98

delivery and performance of any Credit Document, or (ii) the legality, validity,
binding effect or enforceability of any such Credit Document.

             (5) To the best of our knowledge, there are no actions, suits, or
proceedings pending or threatened (i) with respect to any Credit Document or
(ii) that could materially and adversely affect the business, operations,
property, assets, condition (financial or otherwise) or prospects of the
Company.

        (6) The Company is not an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

        (7) The Company is not a "holding company" or a "subsidiary company" of
a "holding company" within the meaning of the Public Utility Holding Company Act
of 1935, as amended.

        (8) The execution and delivery of the Loan Agreement by the Borrower is
effective to create a valid and enforceable security interest in favor of the
Lender in the Collateral and the proceeds thereof.

        (9) The Lender will have a valid and duly perfected security interest,
without further requirements for perfection, in (a) the Pledged Mortgages and
Pledged Securities upon the delivery thereof to the Lender and (b) the other
Collateral described in the Financing Statements to the extent that a security
interest therein may be perfected under Article 9 of the UCC solely by filing a
financing statement with the Secretary of State of California, which lien shall
be superior to any other interests therein.

        3. COMMENTS, ASSUMPTIONS, LIMITATION, QUALIFICATIONS AND EXCEPTIONS.

        The opinions expressed in Section B above are based upon, and subject
to, the further comments, assumptions, limitations, qualifications and
exceptions set forth below:

                             Respectfully submitted,

                                 PROMISSORY NOTE


$50,000,000.00                    Houston, Texas                February 2, 1999

        FOR VALUE RECEIVED, the undersigned, BNC MORTGAGE, INC., a Delaware
corporation (herein called the "Borrower"), hereby promises to pay to the order
of BANK UNITED, a federal savings bank (the "Lender" or, together with its
successors and assigns, the "Holder") whose principal place of business is 3200
Southwest Freeway, Suite 1300, Houston, Texas 77027, or at such other place as
the Holder may designate from time to time, the principal sum of FIFTY MILLION
AND NO/100 DOLLARS ($50,000,000.00) or so much thereof as may be outstanding
from time to time pursuant to the Warehousing Credit and Security Agreement (the
"Agreement") dated the date hereof between the Borrower and the Lender, as the
same may be amended or supplemented from time to time, and to pay interest on
said principal sum or such part thereof as shall remain unpaid from time to
time, from the date of each Advance until repaid in full, and all other fees and
charges due under the Agreement, at the rate and at the times set forth in the
Agreement. All payments hereunder shall be made in lawful money of the United
States and in immediately available funds.

        This Note is given to evidence an actual warehouse line of credit in the
above amount and is the Note referred to in the Agreement, and is entitled to
the benefits thereof. Reference is hereby made to the Agreement (which is
incorporated herein by reference as fully and with the same effect as if set
forth herein at length) for a description of the Collateral, a statement of the
covenants and agreements, a statement of the rights and remedies and securities
afforded thereby and other matters contained therein. Capitalized terms used
herein, unless otherwise defined herein, shall have the meanings given them in
the Agreement.

        The entire unpaid principal balance of this Note plus all accrued and
unpaid interest shall be due and payable in full on February 1, 2000.

        This Note may be prepaid in whole or in part at any time without premium
or penalty.

        Should this Note be placed in the hands of attorneys for collection, the
Borrower agrees to pay, in addition to principal and interest, fees and charges
due under the Agreement, and all costs of collecting this Note, including
reasonable attorneys' fees and expenses.

        This Note shall be construed and enforced in accordance with the laws of
the State of Texas, without reference to its principles of conflicts of law, and
applicable federal laws of the United States of America.

        This Note is secured by all security agreements, collateral assignments,
deeds of trust and lien instruments executed by the Borrower in favor of Lender,
or executed by any other Person as security for this Note, including any
executed prior to, simultaneously with, or after the date of this Note.

        The Borrower and any and each co-maker, guarantor, accommodation party,
endorser or other Person liable for the payment or collection of this Note
expressly waives notice, presentment,


                                  EXHIBIT "N"                           Page 78
                                  
<PAGE>   100


      The Borrower and any and each co-maker, guarantor, accommodation party,
endorser or other Person liable for the payment or collection of this Note
expressly waives notice, presentment, demand for payment, protest, notice of
protest and non-payment or dishonor, notice of acceleration, notice of intent to
accelerate, notice of intent to demand, bringing of suit, and diligence in
taking any action to collect amounts called for hereunder and in the handling of
Collateral at any time existing as security in connection herewith, and shall be
directly and primarily liable for the payment of all sums owing and to be owing
hereon, regardless of and without any notice, diligence, act or omission as or
with respect to the collection of any amount called for hereunder or in
connection with any Lien at any time had or existing as security for any amount
called for hereunder.

      It is the intention of the parties hereto to conform strictly to usury
laws applicable to the Lender. Accordingly, if the transactions contemplated
hereby would be usurious under applicable law (including the laws of the United
States of America and the State of Texas), then, in that event, notwithstanding
anything to the contrary herein or in the Agreement or in any other Loan
Document or agreement entered into in connection with or as security for this
Note, it is agreed as follows: (i) the aggregate of all consideration which
constitutes interest under law applicable to the Lender that is contracted for,
taken, reserved, charged, or received herein or under the Agreement or under any
of the other aforesaid Loan Documents or agreements or otherwise in connection
herewith shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be credited by the Lender on the principal
amount of the Obligations (or, if the principal amount of the Obligations shall
have been paid in full, refunded by the Lender to the Borrower, as required);
and (ii) in the event that the maturity of this Note is accelerated by reason of
an election of the Lender resulting from any Event of Default under the
Agreement or otherwise, or in the event of any required or permitted prepayment,
then such consideration that constitutes interest under law applicable to the
Lender may never include more than the maximum amount allowed by such applicable
law, and excess interest, if any, provided for in the Agreement or otherwise
shall be canceled automatically as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by the Lender on the
principal amount of the Obligations (or, if the principal amount of the
Obligations shall have been paid in full, refunded by the Lender to the
Borrower, as required). Without limiting the foregoing, all calculations of the
rate of interest taken, reserved, contracted for, charged, received or provided
for under this Note or any of the Loan Documents which are made for the purpose
of determining whether the interest rate exceeds the Maximum Rate shall be made,
to the extent allowed by law, by amortizing, prorating, allocating and spreading
in equal parts during the period of the full stated term of the loan evidenced
hereby, all interest at any time taken, reserved, contracted for, charged,
received, or provided for under this Note of any of the Loan Documents. To the
extent that the Texas Credit Title is relevant for purposes of determining the
Maximum Rate, the Lender hereby elects to determine the applicable rate ceiling
under such statute by the weekly rate ceiling from time to time in effect,
subject to the Lender's right subsequently to change such method in accordance
with applicable law.
