            Section 2.2 Warrant Certificates. The Company shall execute and
deliver the Warrant Certificates in accordance with the terms of, and subject to

                                   ARTICLE III
                       EXERCISE OR CONVERSION OF WARRANTS

            Section 3.1 Exercise or Conversion. Any or all of the Warrants
represented by each Warrant Certificate which have vested pursuant to Section
2.1 may be exercised or converted, upon the terms and subject to the conditions
set forth herein and in such Warrant Certificate, at any time on or after the
date of such Warrant and before the Expiration Date. Each Warrant not exercised
or converted on or before the Expiration Date shall thereupon become void and
all rights of the Holder thereunder and under this Agreement shall cease. In the
event that less than all of the Warrants evidenced by a Warrant Certificate
surrendered upon the exercise of Warrants are exercised at any time prior to the
Expiration Date, a new Warrant

                                      -3-
<PAGE>

Certificate or Certificates will be issued for the remaining number of Warrants
evidenced by the Warrant Certificate so surrendered.

            Section 3.2 Time of Exercise or Conversion. Each exercise or
conversion of Warrants shall be deemed to have been effective immediately prior
to the close of business on the business day on which the Warrant Certificate
relating to such Warrant shall have been surrendered as provided in Section 3.1
and in such Warrant Certificate. Thereafter, the Holder shall have, with respect
to the Warrant Shares purchased or otherwise acquired upon exercise or
conversion, all the rights and obligations of any other stockholder of the
Company holding Common Stock.

                       CERTAIN OBLIGATIONS OF THE COMPANY

            Section 4.1 Performance by the Company.

            (a) The Company has reserved and shall at times keep reserved, out
of the authorized and unissued capital stock of the Company, such number of
Warrant Shares sufficient to provide for the exercise of the rights of purchase
represented by all Warrants issued pursuant to this Agreement. The Company shall
authorize and direct the transfer agent for the Common Stock (and any successor
thereto, the "Transfer Agent") at all times to reserve such number of Warrant
Shares as may be issuable upon exercise of outstanding Warrants under this
Agreement. The Company shall provide a copy of this Agreement and each Warrant
Certificate issued hereunder to the Transfer Agent. The Company shall, at its
expense, use its best efforts to cause the Warrant Shares to be listed (subject
to official notice of issuance) on the Nasdaq Stock Market and such other stock
exchanges, if any, or markets on which the Common Stock may become listed from
and after the date of issuance of such Warrants through the Expiration Date.

            (b) The Company will not, by any voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of this Agreement or the
Warrant Certificate, but will at all times in good faith assist in the carrying
out of all such terms. Without limiting the generality of the foregoing, the
Company (i) shall take all such action as may be necessary or appropriate in
order that the Company may validly and legally issue the Warrant Shares upon the
exercise of all Warrants from time to time outstanding, and (ii) will not (A)
transfer all or substantially all of its properties and assets to any other
person or entity, (B) consolidate with or merge into any other entity where the
Company is not the surviving entity, or (C) permit any other entity to
consolidate with or merge into the Company, where the Company is not the
surviving entity, where in connection with such transfer, consolidation or
merger, the Warrant Shares then issuable upon the exercise of the Warrant shall
be changed into or exchanged for shares or other securities or property of any
other entity unless, in any such case, the other entity acquiring such
properties and assets, continuing or surviving after such consolidation or
merger or issuing or distributing such shares or other securities or property,
as the case may be, shall expressly assume in writing and be bound by all the
terms of this Agreement and the Warrant Certificates.

            Section 4.2 Repurchase or Redemption of Common Stock. The Company
will not repurchase or otherwise redeem outstanding shares of its Common Stock
if such repurchase or redemption would cause USB's ownership of Common Stock
(assuming conversion of all shares of Preferred Stock) to exceed 24.99% of the
outstanding shares of Common Stock, without the consent of USB, unless or until
the Company has made provision to redeem or otherwise repurchase a sufficient
number of shares of the Preferred Stock or Common Stock then held by USB such
that USB's ownership of Common Stock (assuming conversion of all shares of
Preferred Stock) does not exceed 24.99% of the outstanding shares of Common
Stock.

            Section 4.3 No Predatory Lending. For so long as USB owns any of the
Preferred Stock or Common Stock of the Company, (i) the Company will not, and
will not allow NCMC or any other subsidiary, to engage in any "predatory
behaviors" (as defined in that certain letter dated April 4, 2000 from USB to
the Company), and (ii) the Company will provide USB with a quarterly report, on
or as soon as reasonably practicable after the last business day of each fiscal
quarter, regarding the Company's and its subsidiaries' adherence to
non-predatory lending practices during that fiscal quarter.

            Section 4.4 Cooperation; Further Assurances. The Company shall
cooperate with USB and use its commercially reasonable efforts to take such
actions, or to cause to be made such amendments to this Agreement and the
agreements and certificates referred to herein, as may be reasonably requested
by USB as necessary, proper or advisable under applicable regulations, policies
and guidelines of the Board of Governors of the Federal Reserve System, the
Office of the Comptroller of the Currency or other applicable bank regulatory
authority.

                    RIGHTS OF HOLDERS OF WARRANT CERTIFICATES

            Section 5.1 No Rights of Holders of Common Stock. The Warrant
Certificates shall be issued in registered form only. No Warrant Certificate
shall entitle the Holder thereof to any of the rights of a holder of Common
Stock of the Company, including, without limitation, the right to vote, to
receive other distributions, to elect directors of the Company or to receive
notice of or to attend the meetings of stockholders or any other proceeding of
the Company.

            Section 5.2 Loss, Theft, Destruction or Mutilation of Warrant
Certificates. In case any of the Warrant Certificates shall be lost, stolen,
destroyed or mutilated, the Company will issue and deliver in exchange and
substitution for and upon cancellation of the mutilated Warrant Certificate, or
in lieu of and substitution for the Warrant Certificate lost, stolen or
destroyed, a new Warrant Certificate of like tenor and representing an
equivalent right or interest, but (a) in the case of such loss, theft or
destruction, only upon receipt of evidence satisfactory to the Company of such
loss, theft or destruction of such Warrant Certificate and indemnity, if
requested, also satisfactory to it or (b) in the case of any such mutilation,
only upon surrender to and cancellation by the Company of such Warrant
Certificate.

Warrants, the rights thereunder and the Warrant Shares may be sold, transferred
or otherwise disposed of or in any manner transferred upon the books of the
Company, in whole or in part, (a) to a successor to US Bank or any affiliate of
US Bank and (b) to any other person or entity, subject to the requirements of
the Securities Act and any applicable state securities law. Any such transfer
may be made at the principal office of the Company by the Holder of such Warrant
in person or by duly authorized attorney, upon surrender of the Warrant properly
endorsed. Upon surrender for transfer or exchange of any Warrant Certificate,
properly endorsed, to the Company, the Company will issue and deliver to or upon
the order of the Holder thereof a new Warrant Certificate of like tenor, in the
name of such Holder or as such Holder (upon payment by such Holder of any
applicable transfer taxes) may direct. Any Warrant Certificate surrendered for
transfer or exchange shall be canceled by the Company.

                                   ARTICLE VII

                                 PROMISSORY NOTE

$40,000,000.00                                                    April 28, 2000

      FOR VALUE RECEIVED, the undersigned, NEW CENTURY MORTGAGE CORPORATION (the
"Borrower"), hereby promises to pay to the order of U.S. BANK NATIONAL
ASSOCIATION (the "Lender", which term includes any subsequent holder hereof) at
Minneapolis, Minnesota or at such other place as the Lender may from time to
time hereafter designate to the Borrower in writing the principal sum of all
loans made by the Lender to the Borrower evidenced by this Note. The aggregate
principal amount of all such loans outstanding hereunder shall not exceed FORTY
MILLION DOLLARS AND NO CENTS ($40,000,000.00). The amount and date of each loan
evidenced hereby shall be entered by the Lender into its records, which records
shall be conclusive evidence of the subject matter thereof absent manifest

      The unpaid principal balance hereof from time to time outstanding shall
bear interest at the rate of twelve percent (12.0%) per annum. Interest shall be
computed on the basis of actual days elapsed and a year of 360 days. Upon the
happening of any Event of Default, this Note, at the option of the Lender, shall
bear interest until paid in full at a rate per annum equal to the rate of
interest applicable immediately prior to such Event of Default plus two percent
(2.0%) per annum. Interest shall be payable monthly in arrears five (5) business
days after the end of the preceding calendar month, and at final maturity.

      The entire principal balance hereof and all accrued, unpaid interest
hereon is payable on June 1, 2002.

      This Note is the Note referred to in the Subordinated Loan Agreement of
even date herewith between the Borrower and the Lender (as the same may be
amended, modified or restated from time to time, the "Subordinated Loan
Agreement"). Terms capitalized and used herein without being defined will have
the meanings given to them in the Subordinated Loan Agreement.

      Payment of this Note is subordinated to payment of all obligations of the
Borrower to the Lender and certain other lenders who are parties to the
Warehousing Agreement pursuant to that certain Subordination Agreement dated as
of October 14, 1999 made by the Lender in favor of such lenders. This Note is
the "Subordinated Note" referred to in such Subordination Agreement.

      This Note is secured by liens granted pursuant to (i) the Amended and
Restated Pledge and Security Agreement of even date herewith, made and given by
the Borrower (as the same may hereafter be amended, modified or supplemented, or
any agreement entered into in substitution or replacement therefor, the "Pledge
and Security Agreement"), (ii) the Amended and Restated Servicing Security
Agreement of even date herewith, made and given by the Borrower (as the same may

      The occurrence of any one or more of the following events shall constitute
an Event of Default, and upon the occurrence of any Event of Default the Lender
may exercise all rights and remedies under the Subordinated Loan Agreement, the
Security Documents and as may otherwise be allowed by applicable law:

      (1)   The Borrower shall fail to make any payment of principal or interest
            hereon when due.

      (2)   The Borrower shall become insolvent or shall generally not pay its
            debts as they mature or shall apply for, shall consent to, or shall
            acquiesce in the appointment of a custodian, trustee or receiver for
            the Borrower or for a substantial part of the property thereof or,
            in the absence of such application, consent or acquiescence, a
            custodian, trustee or receiver shall be appointed for the Borrower
            or for a substantial part of the property thereof; or any
            bankruptcy, reorganization, debt arrangement or other proceedings
            under any bankruptcy or insolvency law shall be instituted by or
            against the Borrower.

      (3)   The maturity of any material indebtedness of the Borrower (other
            than the indebtedness on this Note) shall be accelerated or the
            Borrower shall fail to pay any such material indebtedness when due
            or, in the case of indebtedness payable on demand, when demanded.
            For these purposes, indebtedness of the Borrower shall be deemed
            material if it exceeds $250,000 as to any item of indebtedness or in
            the aggregate for all items of

                                     - 2 -

            indebtedness with respect to which any of the events described in
            this paragraph has occurred.

      (4)   Any default shall occur under the terms of any Security Document and
            shall continue for more than the period of grace, if any, applicable
            thereto.

      (5)   An "Event of Default" as defined in the Warehousing Agreement as in
