(1) Pursuant to Rule 457(f)(2) under the Securities Act of 1933, as amended (the
    "Securities Act"), U.S.$90,910 was paid on November 25, 1997 by NB Capital
    Corporation in connection with its filing of a Registration Statement on
    Form S-4/F-9 (Registration Statement Nos. 333-41009, 333-41009-01 and
    333-41009-02) ("Form S-4/F-9") related to 300,000 shares of its 8.35%
    Noncumulative Exchangeable Preferred Stock, Series A ("Preferred Shares").
    Subsequently, the number of Preferred Shares registered on Form S-4/F-9 was
    reduced to 238,400. The remaining 61,600 Preferred Shares were registered on
    a Registration Statement on Form S-11/F-9 (Registration Statement Nos.
    333-46481, 333-46481-01 and 333-46481-02) ("Form S-11/F-9"). No registration
    fee was due at the time of filing the Form S-11/F-9 in connection with the
    registration of the 61,600 Preferred Shares registered thereunder because
    such fee had been previously paid on November 25, 1997 in connection with
    the filing of the Form S-4/F-9. Both the Form S-4/F-9 and the Form S-11/F-9
    were declared effective on March 2, 1998. Each Depositary Share registered
    hereunder represents a one-fortieth interest in a Preferred Share. This
    Registration Statement contains two forms of prospectus. Pursuant to Rule
    429(a) of the General Rules and Regulations under the Securities Act (a) the
    first prospectus which forms a part of this Registration Statement is a
    combined prospectus relating also to (i) Form S-11/F-9 (i.e., Registration
    Statement Nos. 333-46481, 333-46481-01 and 333-46481-02) and (ii) Form
    S-4/F-9 (Registration Statement Nos. 333-41009, 333-41009-01 and
    333-41009-02) and (b) the second prospectus which forms a part of this
    Registration Statement is a combined prospectus relating also to Form
    S-4/F-9 (i.e., Registration Statement Nos. 333-41009, 333-41009-01 and
    333-41009-02. Accordingly, no registration fee is due hereunder in
    connection with the registration of the Depositary Shares.

                                EXPLANATORY NOTE
 
   
    This Registration Statement on Form S-11 contains two forms of prospectus.
The first prospectus is to be used in connection with the (a) issuance of
depositary shares (the "Depositary Shares") of NB Capital Corporation (the
"Company"), each representing a one-fortieth interest in a share of 8.35%
Noncumulative Exchangeable Preferred Stock, Series A (the "Series A Preferred
Shares"), of the Company upon deposit with The Bank of Nova Scotia Trust Company
of New York, as Depositary, of all or a portion of the Series A Preferred Shares
held by Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"),
the initial purchaser of the Series A Preferred Shares and (b) the resale of the
Series A Preferred Shares or the Depositary Shares by Merrill Lynch. The number
of Depositary Shares to be offered by Merrill Lynch is subject to change at any
time since Merrill Lynch may buy and sell Series A Preferred Shares in the open
market. The second prospectus is to be used in connection with the issuance of
Depositary Shares to certain holders of Series A Preferred Shares other than
Merrill Lynch upon deposit by such holders of Series A Preferred Shares with the
Depositary. The two prospectuses are identical except for the front and back
cover pages and the sections entitled "Table of Contents," "Prospectus Summary,"
"Use of Proceeds," "Description of Depositary Shares," "Initial Purchaser"
(which has been deleted from the second prospectus), "Plan of Distribution" and
"Glossary." The form of the first prospectus is included herein and is followed
by the alternate pages to be used in the form of second prospectus. Each of the
alternate pages for the form of second prospectus is labeled "Alternate Page."
If required, final forms of each prospectus will be filed with the Securities
and Exchange Commission under Rule 424(b) of the Securities Act of 1933, as
amended.
    
 
   
    Additionally, pursuant to Rule 429(a) of the General Rules and Regulations
under the Securities Act of 1933, as amended, (a) the first prospectus is a
combined prospectus relating also to (i) the prospectus forming a part of the
Registration Statement on Form S-11/F-9 (Registration Statement Nos. 333-46481,
333-46841-01 and 333-46481-02) and (ii) the prospectus forming a part of the
Registration Statement on Form S-4/F-9 (Registration Statement Nos. 333-41009,
333-41009-01 and 333-41009-02) and (b) the second prospectus is a combined
prospectus relating also to the prospectus forming a part of the Registration
Statement on Form S-4/F-9 (Registration Statement Nos. 333-41009; 333-41009-01
and 333-41009-02). The Form S-11/F-9 and the Form S-4/F-9 were previously
declared effective by the Securities and Exchange Commission on March 2, 1998.

                            ------------------------
 
   
    This Prospectus relates to the offer (the "Offering") by Merrill Lynch,
Pierce, Fenner & Smith Incorporated (the Initial Purchaser") of Depositary
Shares, each representing a one-fortieth interest in a share of 8.35%
Noncumulative Exchangeable Preferred Stock, Series A, par value US$.01 per share
(the "Series A Preferred Shares"), of NB Capital Corporation (the "Company"), a
wholly owned subsidiary of National Bank of Canada (the "Bank") or, as discussed
below, upon the occurrence of an event that results in an automatic exchange (an
"Exchange Event") of Series A Preferred Shares for the Bank's 8.45%
Noncumulative First Preferred Shares, Series Z (the "Bank Preferred Shares"), a
one-fortieth interest in a Bank Preferred Share. As of April 22, 1998, the
Initial Purchaser held of record       Series A Preferred Shares or
approximately    % of the outstanding Series A Preferred Shares. If the Initial
Purchaser were to exchange all of such shares for Depositary Shares, it would
receive       Depositary Shares. The number of Depositary Shares to be offered
by the Initial Purchaser is subject to change at any time since the Initial
Purchaser may buy and sell Series A Preferred Shares in the open market. This
Prospectus may be used by the Initial Purchaser to sell Depositary Shares and
Series A Preferred Shares.
    
 
    The Company's principal business objective is to acquire, hold, finance and
manage assets consisting of obligations secured by real property, as well as
certain other qualifying real estate investment trust ("REIT") assets ("Mortgage
Assets"). The Mortgage Assets currently consist of (i) sixteen "hypothecation
loans" (the "Initial Mortgage Assets") issued to the Company by NB Finance,
Ltd., a wholly owned subsidiary of the Bank ("NB Finance"), that are recourse
only to the "Initial Mortgage Loans" and (ii) cash. Hypothecation loans are
loans secured by the pledge of mortgages as security therefor. The Initial
Mortgage Loans consist of sixteen pools of, at December 31, 1997, 11,692
"Mortgage Loans." Mortgage Loans consist of residential first mortgages insured
by Canada Mortgage and Housing Corporation, an agency of the Government of
Canada ("CMHC"), that are secured by real property located in Canada.
 
    SEE "RISK FACTORS" COMMENCING ON PAGE 16 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY POTENTIAL HOLDERS OF DEPOSITARY SHARES, INCLUDING
THE FOLLOWING:
 
   
    - The Company's income consists principally of payments of interest and,
      therefore, is heavily dependent upon prevailing interest rates.
      Additionally, the Company's income is dependent upon Canadian dollar
      denominated assets. Consequently, a significant decline in interest rates
      or in the value of the Canadian dollar may have an adverse effect on the
      Company, its assets and its ability to make dividend payments with respect
      to the Series A Preferred Shares and, accordingly, the Depositary Shares.
    
 
    - The Company's operations may be affected by prevailing real estate market
      conditions. Consequently, there can be no assurance that prevailing real
      estate market conditions will not adversely affect the Company's ability
      to pay dividends.
 
   
    - All of the residential real properties securing the Initial Mortgage
      Assets issued by NB Finance are, and in the future any real properties
      securing the Mortgage Assets are expected to be, located outside the
      United States, primarily Quebec, Ontario and New Brunswick. Consequently,
      the Company will be subject to the laws of a foreign jurisdiction with
      respect to any actions taken in respect of such real properties and its
      assets may be subject to a greater risk of default than investments in
      comparable U.S. real property.
    
 
   
    - The Initial Mortgage Assets issued by NB Finance are recourse only to the
      Initial Mortgage Loans. Consequently, in the event of default on the
      Initial Mortgage Assets issued by NB Finance, the Company's principal
      recourse will be foreclosure on the real property securing the Initial
      Mortgage Assets issued by NB Finance and, in certain circumstances, CMHC
      insurance may not be available or receipt of payment thereof may be
      delayed.
    
 
    - Dividends on the Series A Preferred Shares are not cumulative.
      Consequently, if the Board of Directors of the Company (the "Board of
      Directors") does not authorize and declare a dividend on the Series A
      Preferred Shares for any particular quarterly dividend period, the holders
      of the Series A Preferred Shares and, accordingly, the Depositary Shares
      would not be entitled to recover such dividend even if funds are, or
      subsequently become, available for payment thereof.
 
   
    - As a subsidiary of the Bank, Canadian banking authorities could, under
      certain circumstances, impose certain restrictions on the operations of
      the Company. Consequently, such restrictions could cause the Company to
      fail to qualify as a REIT as well as affect its ability to pay dividends.
    
 
   
    - The Company may not qualify as a REIT for United States federal income tax
      purposes. Consequently, the Company could be subject to United States
      federal income tax at normal corporate tax rates.
    
 
    - The Board of Directors may amend or revise the Company's policies and
      strategies in the future without a vote of stockholders, including holders
      of the Series A Preferred Shares and holders of Depositary Shares.
      Consequently, the holders of Series A Preferred Shares or Depositary
      Shares cannot preclude the Board of Directors from making such amendments
      or revisions even though the ultimate effect on the holders of Series A
      Preferred Shares and holders of Depositary Shares may be negative.

 THE SECURITIES DESCRIBED HEREIN HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
  SECURITIES AND EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE
          ACCURACY OR DETERMINED THE ADEQUACY OF THIS PROSPECTUS. ANY
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
                            ------------------------
 
   
                 The date of this Prospectus is April   , 1998.
    
<PAGE>
(COVER CONTINUED)
 
   
    - The assets of the Company consist of obligations that do not provide for
      complete amortization of principal over their term to maturity and,
      therefore, require a balloon payment. Consequently, holders of Series A
      Preferred Shares and, accordingly, holders of Depositary Shares may be
      accepting a greater degree of risk relative to an investment with
      underlying assets that are comprised of fully amortizing obligations.
    
 
    - The Company has not obtained a third party valuation of its assets for the
      purposes of the Offering. Consequently, there can be no assurance that the
      fair market value of such assets does not differ from the purchase price
      thereof.
 
   
    - Under certain circumstances, including when the Bank is experiencing
      financial difficulties or its financial condition is deteriorating, the
      Series A Preferred Shares could be exchanged automatically for the Bank
      Preferred Shares (i.e., an Exchange Event). Immediately upon the
      occurrence of an Exchange Event, each Depositary Share will represent a
      one-fortieth interest in a Bank Preferred Share and will no longer
      represent a fractional interest in a Series A Preferred Share.
      Consequently, the Depositary Shares could represent an investment in the
      Bank and not in the Company at a time when the Bank is experiencing such
      financial difficulties or such deterioration of financial condition.
    
 
    - The Company is dependent upon the Bank and its affiliates in virtually
      every phase of its operations. However, the interests of the Company and
      the Bank may not be identical. Consequently, because of the relationship
      between the Company and the Bank and its affiliates, conflicts of interest
      may arise between the Company and the Bank.
 
    - The assignment of the Initial Mortgage Loans to the Company has not been
      registered. Consequently, a bona fide purchaser who completes all
      necessary registration formalities prior to the Company would be
      recognized as the owner of the Initial Mortgage Loans.
 
    - The Company intends to list the Depositary Shares on the New York Stock
      Exchange (the "NYSE"). The Company is under no obligation, and currently
      has no intention, to list the Series A Preferred Shares on a national
      exchange. Additionally, there is no existing market for the Series A
      Preferred Shares and there can be no assurance as to the liquidity of any
      markets that may develop, the ability of holders to sell their Series A
      Preferred Shares or the sale price thereof. Consequently, holders of
      Series A Preferred Shares may find it difficult to sell their Series A
      Preferred Shares or to sell their Series A Preferred Shares at a price
      equivalent to the purchase price thereof.
 
   
    The Series A Preferred Shares and the Depositary Shares may be sold by the
Initial Purchaser directly to purchasers, through agents designated from time to
time, through underwriting syndicates led by one or more managing underwriters
or through one or more underwriters acting alone. The Series A Preferred Shares
and the Depositary Shares offered hereby are offered subject to prior sale,
withdrawal, cancellation or modification of the offer without notice. It is
expected that delivery of the certificates representing Series A Preferred
Shares and receipts representing Depositary Shares will initially be made at the
offices of Shearman & Sterling, New York, New York, on or about          , 1998.
The Series A Preferred Shares and, accordingly, the Depositary Shares represent
an obligation of the Company and do not represent an obligation of NB Finance,
or prior to an Exchange Event, the Bank.
    
 
 CERTAIN PERSONS PARTICIPATING IN THE OFFERING MAY ENGAGE IN TRANSACTIONS THAT
 STABILIZE, MAINTAIN, OR OTHERWISE AFFECT THE PRICE OF THE PREFERRED SHARES OR
     THE DEPOSITARY SHARES. SUCH TRANSACTIONS MAY INCLUDE STABILIZING,THE
      PURCHASE OF THE PREFERRED SHARES OR THE DEPOSITARY SHARES TO COVER
         SYNDICATE SHORT POSITIONS AND THE IMPOSITION OF PENALTY BIDS.

                                  THE COMPANY
 
GENERAL
 
    The Company is a Maryland corporation incorporated on August 20, 1997. The
Bank was the organizer of the Company. All of the common stock, par value $.01
per share, of the Company (the "Common Stock") is owned by National Bank of
Canada (the "Bank"). The Company's principal business objective is to acquire,
hold, finance and manage assets consisting of obligations secured by real
property, as well as certain other qualifying REIT assets ("Mortgage Assets").
The Company will elect to be taxable as a REIT under the Internal Revenue Code
of 1986, as amended (the "Code"), and generally will not be liable for United
States federal income tax to the extent that it distributes its income to its
stockholders and maintains its qualification as a REIT. See "United States
Federal Income Tax Considerations-- Qualification of the Company as a REIT." The
Bank has indicated to the Company that, for as long as any of the Series A
Preferred Shares are outstanding, the Bank intends to continue to own all of the
outstanding shares of the Common Stock. The Company was formed to provide
investors with the opportunity to invest in Canadian residential mortgages and
other real estate assets and to provide the Bank with a cost-effective means of
raising capital. The Company began operations on September 3, 1997.
 
    The Company's charter (the "Charter") and bylaws (the "Bylaws") both become
operational on August 20, 1997. Pursuant to the Charter, the duration of the
Company is perpetual, except that effective as of the close of business on the
date the Company delivers a notice of an Exchange Event, without the need for
any approval by the Board of Directors or the stockholders of the Company, the
existence of the Company will terminate and the Company will be liquidated and
its affairs wound up in accordance with Maryland law.
 
MORTGAGE ASSETS
 
   
    The Company's Mortgage Assets currently consist of (i) sixteen hypothecation
loans (the "Initial Mortgage Assets"), in an aggregate amount at December 31,
1997 of US$457 million, issued to the Company by NB Finance that are recourse
only to the "Initial Mortgage Loans" and (ii) cash. The Initial Mortgage Loans
consist of sixteen pools of, at December 31, 1997, 11,692 "Mortgage Loans" in an
aggregate amount at December 31, 1997 of C$793 million (US$554 million).
Accordingly, the Initial Mortgage Assets issued by NB Finance are
over-collateralized by US$97 million. Mortgage Loans consist of CMHC-insured
residential first mortgages that are secured by real property located in Canada.
The Initial Mortgage Assets issued by NB Finance will mature semiannually
beginning in 2000 and the proceeds thereof (net of distributions and expenses)
are expected to be reinvested in additional Mortgage Assets as described under
"Business and Strategy--Description of Mortgage Assets; Investment Policy."
    
 
    The Company acquired the Initial Mortgage Assets (which are U.S. dollar
denominated) backed by the Initial Mortgage Loans (which are Canadian dollar
denominated), rather than purchasing the Initial
 
                                       1
<PAGE>
Mortgage Loans directly, in order to eliminate potential foreign exchange gain
or loss and to provide a U.S. dollar denominated income stream that matched its
obligations on the Preferred Stock.
 
SERIES A PREFERRED SHARES
 
   
    On September 3, 1997 (the "Issue Date"), 300,000 Series A Preferred Shares
were issued and sold to Merrill Lynch, Pierce, Fenner & Smith Incorporated (the
"Initial Purchaser") in a transaction not registered under the Securities Act of
1933, as amended (the "Securities Act") in reliance upon an exemption from the
registration requirements thereof. The Initial Purchaser simultaneously sold
238,400 Series A Preferred Shares in transactions exempt from the registration
requirements of the Securities Act in the United States to persons reasonably
believed by the Initial Purchaser to be "qualified institutional buyers" (as
defined in Rule 144A under the Securities Act), to institutional "accredited
investors" (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities
Act) and outside the United States to non-United States persons in offshore
transactions in reliance on Regulation S under the Securities Act. As of April
22, 1998, the Initial Purchaser held of record 61,600 Series A Preferred Shares
or approximately 20.5% of the outstanding Series A Preferred Shares. If the
Initial Purchaser were to exchange all of such shares for Depositary Shares, it
would receive 2,464,000 Depositary Shares. The number of Depositary Shares to be
offered by the Initial Purchaser is subject to change at any time since the
Initial Purchaser may buy and sell Series A Preferred Shares in the open market.
This Prospectus may be used by the Initial Purchaser to sell Depositary Shares
and Series A Preferred Shares.
    
 
    The principal executive offices of the Company are located at 125 West 55th
Street, New York, New York 10019. The telephone number of the Company is (212)
632-8500.
 
                                    THE BANK
 
GENERAL
 
    The Bank was formed through a series of amalgamations and its roots date
back to 1859 with the founding of the Banque Nationale in Quebec City. Its head
office and principal place of business is located at the National Bank Tower,
600 de La Gauchetiere West, Montreal, Quebec, H3B 4L2, and its telephone number
is (514) 394-5000.
 
    The Bank is a Schedule I bank under the Consolidated Bank Act (Canada), as
amended (the "Bank Act"). The Bank Act is the charter governing all banks in
Canada (both domestic banks and branches of foreign banks operating in Canada).
"Schedule I" of the Bank Act lists all Canadian domestic banks. "Schedule II" of
the Bank Act lists all subsidiaries of foreign banks with branches in Canada.
The specific provisions of the Bank Act that govern a particular bank depend
upon the schedule on which such bank is listed. As a Canadian domestic bank, the
Bank is a "Schedule I Bank."
 
    The Bank, which ranks sixth among Canadian banks in terms of total assets,
is present in each of Canada's provinces. It delivers an extensive range of
financial services to individuals, commercial enterprises, financial
institutions and governments both in Canada and abroad.
 
    Additional information regarding the Bank is included in the Bank's
short-form prospectus related to the Bank Preferred Shares affixed to this
Prospectus as Annex A.
 
PREFERRED SHARES OF THE BANK
 
    The authorized preferred capital of the Bank consists of an unlimited number
of First Preferred Shares ("First Preferred Shares") and up to 15 million Second
Preferred Shares which may be issued for a maximum aggregate consideration of
C$1 billion and C$300 million, respectively, or the equivalent thereof in other
currencies. The Board of Directors of the Bank may by resolution establish the
terms of series of preferred shares. The Bank currently has six series of First
Preferred Shares outstanding with an aggregate liquidation preference as of
October 31, 1997 of C$376 million.

CANADIAN STATUTORY REQUIREMENTS
 
    Under Canadian law, the Bank is required to maintain adequate capital in
relation to its operations. The Office of the Superintendent of Financial
Institutions Canada (the "Superintendent") has issued guidelines concerning the
maintenance of adequate capital (the "Capital Guideline") and has statutory
authority to direct the Bank to increase its capital even if the Bank is in
compliance with the Capital Guideline. Pursuant to the Capital Guideline,
requirements are applied to the Bank on a consolidated basis including all
subsidiaries except insurance subsidiaries or other regulated financial
institutions whose leverage is inappropriate for a deposit-taking institution
and that, because of their size, would have a material impact on the leverage of
the consolidated entity. Under the Capital Guideline, it is expected that the
Bank's total assets, including specified off-balance sheet items, should be no
greater than 20 times the Bank's total capital. It is also expected that the
Bank's total capital will not be less than 8% of risk-weighted assets and
risk-weighted off-balance sheet items, unless a higher ratio is prescribed by
the Superintendent. The Capital Guideline prescribes risk-weighting and the
treatment of off-balance sheet items. The ratio of total capital to
risk-weighted off-balance sheet items is the "risk-based capital ratio" and is
based upon standards adopted by the Bank for International Settlement. The
Capital Guideline recognizes two tiers of capital. Tier 1 capital comprises the
highest quality capital elements based upon the attributes of permanence,
freedom from mandatory fixed charges against earnings and subordination to the
rights of depositors and other creditors. Tier 2 capital contributes to the
overall strength of a bank as a going concern, but falls short in meeting the
first two capital attributes described for Tier 1 capital. Tier 2 capital
differentiates between Tier 2A hybrid (debt/equity) instruments and Tier 2B
limited life instruments. Tier 1 capital elements consist of common
shareholders' equity, qualifying noncumulative perpetual preferred shares and
qualifying non-controlling interests in subsidiaries arising on consolidation
from Tier 1 capital instruments. Tier 1 capital instruments and preferred shares
qualifying as hybrid instruments in Tier 2A are intended to be permanent. When
the share or instrument provides for redemption by the issuer after five years
with supervisory approval, the Superintendent would not normally prevent such
redemption by a healthy and viable bank when the instrument is or has been
replaced by equal or higher quality capital including an increase in retained
earnings, or if the bank is downsizing. All capital instruments must be issued
and fully paid for in money or, with the approval of the Superintendent, in
property. Net of amortization, the amount of Tier 2 capital may not exceed 100%
of Tier 1 capital after deducting goodwill and, consequently, the Capital
Guideline requires the amount of Tier 1 capital to be not less than 4% of
risk-weighted assets and risk-weighted off-balance sheet items, unless a higher
ratio is prescribed by the Superintendent. Also under the Capital Guideline, the
amount of Tier 2B capital net of amortization shall not exceed 50% of Tier 1
capital after deducting goodwill.
 
    After giving effect to the issuance of the Series A Preferred Shares on
September 3, 1997, the Tier 1 risk-based capital ratio and total risk-based
capital ratio levels of the Bank as of October 31, 1997 were 8.1% and 11.3%,
respectively. The Bank's Tier 1 risk-based capital ratio and total risk-based
capital ratio were 6.9% and 10.2% at October 31, 1996, 6.8% and 10.4% at October
31, 1995 and 6.9% and 11.1% at October 31, 1994.
 
    Section 485 of the Bank Act requires Canadian banks to maintain adequate
capital and adequate and appropriate forms of liquidity and to comply with
related regulations. Under subsection 485(3), the Superintendent may, by order,
direct a bank to increase its capital or to provide additional liquidity in such
forms and amounts as the Superintendent may require. The Superintendent may act
under subsection 485(3) even if a bank is in compliance with all applicable
guidelines and regulations.
 
EXCHANGE EVENT
 
    Each of the Series A Preferred Shares will be exchanged automatically (the
"Automatic Exchange") for one Bank Preferred Share (i) immediately prior to such
time, if any, at which the Bank fails to declare and pay or set aside for
payment when due any dividend on any issue of its cumulative First Preferred
Shares or the Bank fails to pay or set aside for payment when due any declared
dividend on any of its
 
                                       3
<PAGE>
noncumulative First Preferred Shares, (ii) in the event that the Bank has a Tier
1 risk-based capital ratio of less than 4.0% or a total risk-based capital ratio
of less than 8.0%, (iii) in the event that the Superintendent takes control of
the Bank pursuant to the Bank Act, or proceedings are commenced for the
winding-up of the Bank pursuant to the Winding-up and Restructuring Act
(Canada), or (iv) in the event that the Superintendent, by order, directs the
Bank to act pursuant to subsection 485(3) of the Bank Act and the Bank elects to
cause the exchange (each, an "Exchange Event"). Immediately upon the occurrence
of an Exchange Event, each Depositary Share will represent a one-fortieth
interest in a Bank Preferred Share and no longer represent a fractional interest
in a Series A Preferred Share. In connection with the Exchange Offer, the Bank
Preferred Shares were registered with the Commission. See "Risk Factors--
Certain Risks Associated with the Bank" and "Description of Series A Preferred
Shares--Automatic Exchange."
 
                                   NB FINANCE
 
   
    NB Finance was incorporated on September 3, 1997 under the laws of Bermuda.
The Bank was the organizer of NB Finance. NB Finance was organized solely for
the purpose of acquiring Mortgage Loans and issuing the Initial Mortgage Assets
and other similar obligations to the Company. All of the ordinary shares of NB
Finance are owned by the Bank. Pursuant to an order (the "OSFI Order") of the
Superintendent, the acquisition of the common stock of NB Finance by the Bank
was approved on September 2, 1997. Such approval was, however, conditional upon
(i) the Bank continuing to own at all times such common stock, (ii) NB Finance
not incurring any indebtedness (other than to the Company) and (iii) NB Finance
not engaging in any business activities other than the ownership of Mortgage
Loans and activities incidental thereto. See "Business and Strategy--Description
of the Initial Mortgage Loans." Accordingly, the Bank has indicated to the
Company that it intends to maintain 100% ownership of the ordinary shares of NB
Finance so long as the Initial Mortgage Assets issued by NB Finance or any other
obligations of NB Finance are owned by the Company. The registered offices of NB
Finance are located at Clarendon House, 2 Church Street, Hamilton HM11, Bermuda.
NB Finance does not have a telephone number.
    
 
    NB Finance's Memorandum of Association (the "Memorandum") and bye-laws (the
"Bye-laws") both became operational on September 3, 1997. Pursuant to the
Bye-laws, the duration of NB Finance is perpetual until it is wound up in
accordance with Bermuda law. Notwithstanding the foregoing, immediately
following notice to NB Finance that the Company has delivered a notice of an
Exchange Event, the Board of Directors of NB Finance will convene a special
meeting of stockholders for the purpose of approving the voluntary winding-up of
NB Finance in accordance with Bermuda law.

                             ORGANIZATIONAL DIAGRAM
 
   
    The following diagram outlines the relationship between the Bank, the
Company, NB Finance and the Depositary relevant to the Offering:
    
 
                                   [DIAGRAM]
 
- ------------------------
 
(1) CMHC-insured residential first mortgages originated by the Bank or acquired
    by the Bank from other NHA- Approved Lenders (as defined).
 
(2) Secured by residential real property and recourse only to the Initial
    Mortgage Loans.
 
(3) Subject to automatic exchange of the Bank Preferred Shares in certain
    circumstances. Series A Preferred Shares can be deposited with the
    Depositary against receipt of Depositary Shares.
 
(4) Each Depositary Share represents one-fortieth of an interest in a Series A
    Preferred Share.
 
                              SUMMARY RISK FACTORS
 
    The Depositary Shares offered hereby are subject to certain risks. See "Risk
Factors." Among such risks are the following:
 
   
    - The Company's income consists principally of payments of interest and,
      therefore, is heavily dependent upon prevailing interest rates.
      Additionally, the Company's income is dependent upon Canadian dollar
      denominated assets. Consequently, a significant decline in interest rates
      or in the value of the Canadian dollar may have an adverse effect on the
      Company, its assets and its ability to
    
 
                                       5
<PAGE>
      make dividend payments with respect to the Series A Preferred Shares and,
      accordingly, the Depositary Shares.
 
    - The Company's operations may be affected by prevailing real estate market
      conditions. Consequently, there can be no assurance that prevailing real
      estate market conditions will not adversely affect the Company's ability
      to pay dividends.
 
   
    - All of the residential real properties securing the Initial Mortgage
      Assets issued by NB Finance are, and in the future any real properties
      securing the Mortgage Assets are expected to be, located outside the
      United States, primarily in Quebec, Ontario and New Brunswick.
      Consequently, the Company will be subject to the laws of a foreign
      jurisdiction with respect to any actions taken in respect of such real
      properties and its assets may be subject to a greater risk of default than
      investments in comparable U.S. real property.
    
 
   
    - The Initial Mortgage Assets issued by NB Finance are recourse only to the
      Initial Mortgage Loans. Consequently, in the event of default on the
      Initial Mortgage Assets issued by NB Finance, the Company's principal
      recourse will be foreclosure on the real property securing the Initial
      Mortgage Assets issued by NB Finance and, in certain circumstances, CMHC
      insurance may not be available or receipt of payment thereof may be
      delayed.
    
 
    - Dividends on the Series A Preferred Shares are not cumulative.
      Consequently, if the Board of Directors does not authorize and declare a
      dividend on the Series A Preferred Shares for any particular quarterly
      dividend period, the holders of the Series A Preferred Shares and,
      accordingly, the Depositary Shares would not be entitled to recover such
      dividend even if funds are, or subsequently become, available for payment
      thereof.
 
   
    - As a subsidiary of the Bank, Canadian banking authorities could, under
      certain circumstances, impose certain restrictions on the operations of
      the Company. Consequently, such restrictions could cause the Company to
      fail to qualify as a REIT as well as affect its ability to pay dividends.
    
 
   
    - The Company may not qualify as a REIT for United States federal income tax
      purposes. Consequently, the Company could be subject to United States
      federal income tax at normal corporate tax rates.
    
 
    - The Board of Directors may amend or revise the Company's policies and
      strategies in the future without a vote of stockholders, including holders
      of the Series A Preferred Shares and holders of Depositary Shares.
      Consequently, the holders of Series A Preferred Shares or Depositary
      Shares cannot preclude the Board of Directors from making such amendments
      or revisions even though the ultimate effect on the holders of Series A
      Preferred Shares and holders of Depositary Shares may be negative.
 
   
    - The assets of the Company consist of obligations that do not provide for
      complete amortization of principal over their term to maturity and,
      therefore, require a balloon payment. Consequently, holders of Series A
      Preferred Shares and, accordingly, holders of Depositary Shares may be
      accepting a greater degree of risk relative to an investment with
      underlying assets that are comprised of fully amortizing obligations.
    
 
    - The Company has not obtained a third party valuation of its assets for the
      purposes of the Offering. Consequently, there can be no assurance that the
      fair market value of such assets does not differ from the purchase price
      thereof.
 
   
    - Under certain circumstances, including when the Bank is experiencing
      financial difficulties or its financial condition is deteriorating, the
      Series A Preferred Shares could be exchanged automatically for Bank
      Preferred Shares. Immediately upon the occurrence of an Exchange Event,
      each Depositary Share will represent a one-fortieth interest in a Bank
      Preferred Share and will no longer represent a fractional interest in a
      Series A Preferred Share. Consequently, the Depositary Shares
    
 
                                       6
<PAGE>
   
      could represent an investment in the Bank and not in the Company at a time
      when the Bank is experiencing such financial difficulties or such
      deterioration of financial condition.
    
 
    - The Company is dependent upon the Bank and its affiliates in virtually
      every phase of its operations. However, the interests of the Company and
      the Bank may not be identical. Consequently, because of the relationship
      between the Company and the Bank and its affiliates, conflicts of interest
      may arise between the Company and the Bank.
 
    - The assignment of the Initial Mortgage Loans to the Company has not been
      registered. Consequently, a bona fide purchaser who completes all
      necessary registration formalities prior to the Company would be
      recognized as the owner of the Initial Mortgage Loans.
 
    - The Company intends to list the Depositary Shares on the NYSE. The Company
      is under no obligation, and currently has no intention, to list the Series
      A Preferred Shares on a national exchange. Additionally, there is no
      existing market for the Series A Preferred Shares and there can be no
      assurance as to the liquidity of any markets that may develop, the ability
      of holders to sell their Series A Preferred Shares or the sale price
      thereof. Consequently, holders of Series A Preferred Shares may find it
      difficult to sell their Series A Preferred Shares or to sell their Series
      A Preferred Shares at a price equivalent to the purchase price thereof.

                             BUSINESS AND STRATEGY
 
GENERAL
 
    The Company's principal business objective is to acquire, hold, finance and
manage Mortgage Assets that will generate net income for distribution to
stockholders. The Mortgage Assets of the Company currently consist of (i) the
Initial Mortgage Assets (sixteen hypothecation loans, in an aggregate amount at
December 31, 1997 of US$457 million, issued by NB Finance to the Company that
are recourse only to the Initial Mortgage Loans (which are sixteen pools of, at
December 31, 1997, 11,692 CMHC-insured residential first mortgages, in an
aggregate amount at December 31, 1997 of C$793 million (US$554 million) and that
are secured by the residential real property underlying the Initial Mortgage
Loans)) and (ii) cash. See "Business and Strategy--Description of the Initial
Mortgage Assets" and "--Description of the Initial Mortgage Loans." The Company
has acquired substantially all of its Mortgage Assets from the Bank and/or
affiliates of the Bank on terms that are comparable to those that could be
obtained by the Company if such Mortgage Assets were purchased from unrelated
third parties. The Company may also from time to time acquire Mortgage Assets
comparable to the Initial Mortgage Assets issued by NB Finance acquired from the
Bank or from unrelated third parties. As of the date of this Prospectus, the
Company has not entered into any agreements with third parties with respect to
the purchase of Mortgage Assets. Other than with respect to the temporary
investment of payments of interest and principal on its Mortgage Assets, the
Company anticipates that it will purchase Mortgage Assets from unrelated third
parties only if neither the Bank nor any affiliate of the Bank has an amount or
type of Mortgage Assets sufficient to meet the requirements of the Company.
 
    The Company's current investment policy and current intention is to invest
at least 90% of its portfolio in the Initial Mortgage Assets issued by NB
Finance and obligations that are comparable to the Initial Mortgage Assets
issued by NB Finance. Accordingly, potentially 10% of the Company's portfolio
could consist of investments in other assets permitted under the Company's
investment policy. See "Business and Strategy--Description of the Company's
Investment Policy" and "--Description of the Company's Management Policies."
 
   
    The Company intends and has the ability to hold the Mortgage Assets to
maturity unless there is a prepayment by the customer or a Mortgage Loan is
impaired. Therefore the Company's Mortgage Assets will be recorded as a
long-term investment in the balance sheet of the Company.
    
 
    Pursuant to the OSFI Order, NB Finance is not permitted to engage in any
business activities other than the ownership of Mortgage Loans and activities
incidental thereto.
 
MANAGEMENT
 
    The Board of Directors of the Company is composed of five members, two of
whom are Independent Directors. An "Independent Director" is a director who is
not a current officer or employee of the Company or NB Finance or a current
director, officer or employee of the Bank or any affiliate of the Bank. Pursuant
to the terms of the Series A Preferred Shares, the Independent Directors must
consider the interests of the holders of both the Preferred Stock and the Common
Stock in determining whether any proposed action requiring their approval is in
the best interests of the Company. The Company currently has six employees and
does not anticipate that it will require additional employees. See "Management."
 
    The Board of Directors of NB Finance is composed of seven members, two of
whom are Independent Directors. NB Finance currently has no employees and does
not anticipate that it will require any employees. See "Management."
 
                                       8
<PAGE>
YEAR 2000 ISSUE
 
    Pursuant to the Advisory Agreement, dated as of September 3, 1997, between
the Company and the Bank (the "Advisory Agreement"), the Bank administers the
day-to-day activities of the Company. Pursuant to the Servicing Agreement, dated
as of September 3, 1997, between the Company and the Bank (the "Servicing
Agreement"), the Bank services the Mortgage Loans on behalf of the Company. See
"Risk Factors--Relationship with the Bank and Its Affiliates; Conflicts of
Interest," "--Dependence upon the Bank," "Business and Strategy--Description of
the Initial Mortgage Loans" and "Management--The Bank as Advisor." Accordingly,
the Company does not have a material Year 2000 issue.
 
    The Bank, as originator and servicer of the Mortgage Loans that underlie the
Mortgage Assets and administrator of the day-to-day activities of the Company,
has formulated a detailed plan to address the Year 2000 issue. The Bank expects
to invest C$35 million dollars from 1997 through 2000 to modify computer
software and hardware in relation to the Year 2000 issue. According to such
plan, 30% of computer software and 20% of computer hardware were converted and
certified accurate by December 31, 1997. By December 31, 1998, the Bank expects
95% of computer software and 50% of computer hardware will be converted and
certified accurate. By March 31, 1999, the Bank expects that the conversion and
certification of all remaining computer software and hardware will be complete.
The plan and budget also provide for monitoring such conversion through the Year
2000.
 
    Pursuant to the OSFI Order, NB Finance is not permitted to engage in any
business activities other than the ownership of Mortgage Loans and activities
incidental thereto. Accordingly, NB Finance does not have a material Year 2000
issue.
 
                           TAX STATUS OF THE COMPANY
 
    The Company will elect to be taxable as a REIT under Sections 856 through
860 of the Code, commencing with its taxable year ending December 31, 1997. As a
REIT, the Company generally will not be liable for United States federal income
tax to the extent that it distributes its income to the holders of its Common
Stock and Preferred Stock, including the Series A Preferred Shares and,
accordingly, Depositary Shares, and maintains its qualification as a REIT. See
"United States Federal Income Tax Considerations--Qualifications of the Company
as a REIT."
 
    A REIT is subject to a number of organizational and operational
requirements, including a requirement that it currently distribute to
stockholders at least 95% of its "REIT taxable income." REIT taxable income is
essentially taxable income, as determined in accordance with the Code, with
certain adjustments. The most significant of such adjustments are (i) no
deduction is allowed for dividends received, (ii) a deduction is allowed for
dividends paid (other than the portion of any dividend attributable to net
income from foreclosure property) and for taxes imposed for failing to satisfy
certain statutory REIT requirements, and (iii) net income from foreclosure
property and net income derived from prohibited transactions is excluded from
the determination. Notwithstanding its election to be taxable as a REIT, the
Company may be subject to federal, state and/or local tax. See "Risk
Factors--Tax Risks" and "United States Federal Income Tax Considerations."

                                    In order to qualify as a REIT, the capital stock of the
                                    Company must be held by at least 100 holders during
                                    approximately 90% or more of the taxable year beginning

                                    Income Tax Considerations--Stock Ownership Tests." The
                                    Company has issued shares of a series of cumulative,
                                    senior preferred stock ("Senior Preferred Stock") with
                                    an aggregate liquidation preference of up to US$450,000
                                    and limited transferability to ensure that it meets, and
                                    will continue to meet, the 100 person ownership
                                    requirement for REIT status without having to constantly
                                    monitor the number of holders of Preferred Shares.
                                    Except for the Senior Preferred Stock, additional shares
                                    of Preferred Stock ranking senior to the Series A

                                    of holders of at least two-thirds of the Series A
                                    Preferred Shares and, accordingly, the Depositary
                                    Shares. Additional shares of Preferred Stock ranking on
                                    a parity with the Series A Preferred Shares may not be
                                    issued without the approval of a majority of the Board
                                    of Directors and a majority of the Independent
                                    Directors.
 
DIVIDENDS.........................  Dividends on the Series A Preferred Shares are payable
                                    at the rate of 8.35% per annum of the liquidation
                                    preference (an amount equal to US$83.50 per annum per
                                    share calculated by multiplying the annual dividend rate
                                    of 8.35% by the liquidation preference of US$1,000 per
                                    share, assuming authorization and declaration by the
                                    Board of Directors of four quarterly dividends), if,
                                    when and as authorized and declared by the Board of
                                    Directors. If authorized and declared, dividends are
                                    payable quarterly in arrears on the 30th day of March,
                                    June, September and December in each year, commencing
                                    December 30, 1997. Dividends accrue in each quarterly
                                    period from the first day of such period, whether or not
                                    dividends were paid with respect to the preceding

                                    Preferred Shares-- Redemption," on or after September 3,
                                    2002). On and after September 3, 2007, the Series A
                                    Preferred Shares may be redeemed for cash at the option
                                    of the Company, in whole or in part, at any time and
                                    from time to time, at the redemption prices set forth
                                    herein, plus the quarterly accrued and unpaid dividend,
                                    if any, thereon to the date of redemption. Upon the
                                    occurrence of a Tax Event, on or after September 3,
                                    2002, the Company will have the right to redeem the
                                    Series A Preferred Shares in whole (but not in part) at
                                    a redemption price equal to the Make-Whole Amount (as
                                    defined in "Description of Series A Preferred
                                    Shares--Redemption"), plus the quarterly accrued and
                                    unpaid dividend, if any, thereon to the date of
                                    redemption. Any redemption is subject to the prior
                                    written approval of the Superintendent. See "Description
                                    of Series A Preferred Shares--Redemption." The Series A
                                    Preferred Shares are not subject to any sinking fund or
                                    mandatory redemption and are not convertible into any
                                    other securities of the Company.
 
                                    When the Series A Preferred Shares underlying the
                                    Depositary Shares are subject to redemption, the
                                    Depositary Shares will be redeemed from the proceeds
                                    received by the Depositary resulting from the
                                    redemption, in whole or in part, of the Series A
                                    Preferred Shares held by the Depositary. The redemption
                                    price per Depositary Share will be equal to the
                                    applicable fraction of the redemption price per share
                                    payable with respect to the Series A Preferred Shares.
 
AUTOMATIC EXCHANGE................  Each of the Series A Preferred Shares will be exchanged
                                    automatically for one Bank Preferred Share upon the
                                    occurrence of an Exchange Event. See "Description of
                                    Series A Preferred Shares--Automatic Exchange."
 
                                    Immediately upon the occurrence of an Exchange Event,
                                    each Depositary Share will represent a one-fortieth
                                    interest in a Bank Preferred Share and will no longer
                                    represent a fractional interest in a Series A Preferred
                                    Share.
 
VOTING RIGHTS.....................  Holders of the Series A Preferred Shares will not have

                                    Shares may vote, each of the Series A Preferred Shares
                                    will be entitled to one vote and each holder of a

                                    Shares underlying such holder's Depositary Shares. Each
                                    Depositary Share will, in effect, entitle the holders
                                    thereof to one-fortieth of one vote with respect to
                                    matters on which the Series A Preferred Shares are
                                    entitled to vote. See "Description of Series A Preferred

                                    Any Plan fiduciary that proposes to cause a Plan to
                                    invest in Depositary Shares should consult with its
                                    counsel with respect to the potential applicability of
                                    ERISA and the Code to such investment and whether any
                                    exemption or exemptions would be applicable and
                                    determine on its own whether all conditions of such
                                    exemption or exemptions have been satisfied. Any such
                                    Plan fiduciary should also determine whether the
                                    investment in Depositary Shares is permitted under the
                                    governing Plan instruments and is appropriate for the
                                    Plan in view of the overall investment policy and the
                                    composition and diversification of its portfolio.

                                  RISK FACTORS
 
    Prospective investors should carefully consider the following information in
conjunction with the other information contained in this Prospectus before
purchasing Depositary Shares. This Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ significantly from the results discussed in the forward-looking
statements. Factors that might cause such differences include those discussed
below.
 
INTEREST RATE RISK AND MATURITY OF INITIAL MORTGAGE LOANS
 
    The Company's income currently consists of interest payments from the
Initial Mortgage Assets issued by NB Finance. Interest and principal amounts
generated by the Initial Mortgage Loans currently enable full payment with
respect to the Initial Mortgage Assets. The Initial Mortgage Assets and the
Initial Mortgage Loans mature between January 2000 and July 2001. Consequently,
(i) if there is a significant decline in interest rates at a time when the
Company must reinvest payments of interest and principal, the Company may find
it difficult to purchase additional Mortgage Assets or Mortgage Loans that
generate sufficient income to support the payment of dividends on the Series A
Preferred Shares and, accordingly, the Depositary Shares, and (ii) there can be
no assurance that a significant decline in interest rates would not adversely
affect the Company's ability to pay dividends on the Series A Preferred Shares
and, accordingly, the Depositary Shares.
 
CURRENCY EXCHANGE RATE RISK
 
    The Company's income consists principally of interest payments from the
Initial Mortgage Assets issued by NB Finance and obligations that are comparable
to the Initial Mortgage Assets issued by NB Finance. While the Initial Mortgage
Assets are, and the Company's future Mortgage Assets likely will be, denominated
in United States dollars, Mortgage Loans are denominated and payable in Canadian
dollars. Consequently, if there is a significant decrease in the value of the
Canadian dollar, the value in U.S. dollars of the cash flow from Mortgage Loans
assigned to the Company by NB Finance (including principal payments) may
decrease, which may adversely affect the cash flow to the Company and the
Company's ability to pay the dividends on the Series A Preferred Shares and,
accordingly, the Depositary Shares. From the beginning of 1994 to and including
June 30, 1997, the exchange rate of the Canadian dollar to the United States
dollar has ranged from C$1.3111 to US$1.00 on January 21, 1994 to C$1.4234 to
US$1.00 on January 20, 1995; with an average for such period of C$1.3686 to
US$1.00.
 
REAL ESTATE MARKET CONDITIONS
 
    The results of the Company's operations will be affected by various factors,
many of which are beyond the control of the Company, such as: (i) local and
other economic and political conditions affecting real estate values,
particularly in Quebec, (ii) the level of interest income generated by the
Company's Mortgage Assets, (iii) the market value of the Company's Mortgage
Assets and (iv) the supply of and demand for the Company's Mortgage Assets.
Further, there can be no assurance that the value of the Initial Mortgage Assets
issued by NB Finance, or the value of the real property securing the Initial
Mortgage Assets, will remain at the levels existing on the dates of origination
of the Initial Mortgage Assets issued by NB Finance. Consequently, there can be
no assurance that prevailing real estate market conditions will not adversely
affect the Company's operations and its ability to pay dividends on the Series A
Preferred Shares and, accordingly, the Depositary Shares. These foregoing
factors may also have an effect on the business and financial condition of the
Bank. Consequently, such factors may increase the likelihood of an Exchange
Event.
 
GEOGRAPHIC CONCENTRATION OF THE REAL PROPERTY SECURING THE INITIAL MORTGAGE
  ASSETS
 
    All of the real property securing the Initial Mortgage Assets is
geographically concentrated in Canada, primarily located in Quebec, Ontario and
New Brunswick, and the real property securing additional Mortgage Assets
acquired by the Company is also expected to be geographically concentrated in
Canada.
 
                                       16
<PAGE>
Consequently, any actions taken by or on behalf of the Company with respect to
such real property will be dependent upon the laws of the jurisdictions in which
such real property is located.
 
    In addition, from time to time Canada may experience weaker economic
conditions and housing markets than the United States that may adversely affect
the value of real property and mortgages thereon. Consequently, the Initial
Mortgage Assets issued by NB Finance may be subject to a greater risk of
default, individually and in the aggregate, than comparable obligations secured
by U.S. real property or comparable obligations secured by real property that is
less geographically concentrated.
 
LIMITED RECOURSE NATURE OF CERTAIN MORTGAGE ASSETS; LIMITATIONS ON CMHC
  INSURANCE
 
    The Initial Mortgage Assets issued by NB Finance are recourse only to the
Initial Mortgage Loans, which have been assigned to the Company by NB Finance
and are secured by residential real property underlying the Initial Mortgage
Assets issued by NB Finance. Consequently, in the event of nonpayment of
interest or other default on the Initial Mortgage Assets issued by NB Finance,
the Company's only recourse will be to exercise its rights under the Initial
Mortgage Loans (principally through foreclosure on the real property securing
the Initial Mortgage Assets issued by NB Finance), either directly or through
the Bank.
 
    It is anticipated that additional Mortgage Assets acquired by the Company
will consist of similar limited recourse obligations. The CMHC insurance with
respect to the Initial Mortgage Loans is not a guarantee of timely payment of
principal and interest on such Mortgage Loans. Typically, CMHC will only make
payments pursuant to its insurance after the approved lender has taken certain
actions that may be time consuming and can cause delays in the receipt of such
payments. In addition, the CMHC insurance will cease to be in force if any such
Initial Mortgage Loan is sold to a person other than a lender approved by CMHC
unless such Initial Mortgage Loan continues to be administered by CMHC or a
lender approved by CMHC. The regulations of the CMHC stipulate that the terms of
repayment of Mortgage Loans shall not be altered and that no derogation from the
rights of the mortgagee against the mortgaged property by way of postponement,
partial discharge or otherwise shall be granted without first obtaining the
approval of the CMHC. Consequently, even though the Mortgage Loans are CMHC
insured payments of principal and interest in respect of any Mortgage Loan in
default may not, be available from CMHC or, if available, receipt thereof may be
delayed.
 
TAX RISKS
 
    ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT.
 
   
    The Company intends to operate so as to qualify as a REIT under the Code.
Although the Company believes that it will be owned and organized and will
operate in such a manner, and Shearman & Sterling has rendered an opinion,
described under "United States Federal Income Tax Considerations" below, that,
commencing with the Company's taxable year ending December 31, 1997, the Company
will be organized in conformity with the requirements for qualification as a
REIT, and its proposed method of operation will enable it to meet the
requirements for qualification and taxation as a REIT under the Code, no
transaction closely comparable to that contemplated herein has been the subject
of any administrative pronouncement or judicial decision and no assurance can be
given that the Company will be able to operate in such a manner so as to qualify
as a REIT or to remain so qualified. Qualification as a REIT involves the
application of highly technical and complex Code provisions for which there are
only limited judicial and administrative interpretations. The determination of
various factual matters and circumstances not entirely within the Company's
control, and not addressed by the opinion of Shearman & Sterling, may affect the
Company's ability to qualify as a REIT. Although the Company is not aware of any
proposal in Congress to amend the tax laws in a manner that would materially and
adversely affect the Company's ability to operate as a REIT, no assurance can be
given that new legislation or new regulations, or future administrative
interpretations or court decisions, will not significantly change the tax laws
with respect to qualification as a REIT or the United States federal income tax
consequences of such qualification.
    
 
                                       17
<PAGE>
    The Company is relying on the opinion of Shearman & Sterling, counsel to the
Company, regarding various issues affecting the Company's ability to qualify,
and retain qualification, as a REIT. Such legal opinion is not binding on the
Internal Revenue Service (the "IRS") or the courts and no assurance can be given
that such opinion will not be challenged by the IRS.
 
   
    Consequently, if the Company fails to qualify as a REIT in any taxable year,
(i) the Company would not be allowed a deduction for distributions to
stockholders in computing its taxable income and would be subject to United
States federal income tax on its taxable income in the same manner as a regular,
domestic corporation, (ii) the amount available for distribution to the
Company's stockholders, including the holders of the Series A Preferred Shares
and, accordingly, holders of Depositary Shares, would be reduced for the year or
years involved and (iii) unless entitled to relief under certain statutory
provisions, the Company would be disqualified from treatment as a REIT for the
four taxable years following the year during which REIT qualification was lost.
The failure of the Company to qualify as a REIT would not necessarily give the
Company the right to redeem the Series A Preferred Shares, nor would it give the
holders of the Series A Preferred Shares the right to have their shares
redeemed. See "Description of Series A Preferred Shares--Redemption."
    
 
    Notwithstanding the fact that the Company currently operates in a manner
designed to enable it to qualify as a REIT, future economic, market, legal, tax
and other considerations may cause the Board of Directors to determine that it
is in the best interests of the Company and the holders of the Common Stock and
the Series A Preferred Shares to revoke the Company's REIT election. As long as
any of the Series A Preferred Shares are outstanding, any such determination by
the Company may not be made without the approval of a majority of the
Independent Directors. United States federal income tax law prohibits the
Company from electing to be taxable as a REIT for the four taxable years
following the year of such revocation. See "United States Federal Income Tax
Considerations."
 
    REIT REQUIREMENTS WITH RESPECT TO STOCKHOLDER DISTRIBUTIONS.
 
    To qualify as a REIT under the Code, the Company is generally required each
year to distribute as dividends to its stockholders at least 95% of its "REIT
taxable income" (excluding capital gains). Failure to comply with this
requirement would result in the Company failing to qualify as a REIT.
Consequently, the Company would become subject to tax at normal corporate rates.
In addition, the Company would be subject to a 4% nondeductible excise tax on
the amount, if any, by which certain distributions considered as paid by it with
respect to any calendar year are less than the sum of 85% of its ordinary income
for the calendar year, 95% of its capital gains net income for the calendar year
and any undistributed taxable income from prior periods. Under certain
circumstances, the Superintendent may restrict the ability of the Company, as a
subsidiary of the Bank, to make distributions to its stockholders. Consequently,
such a restriction could result in the Company's failing to satisfy the REIT
requirements with respect to stockholder distributions. See "--Dividend and
Other Regulatory Restrictions on Operations of the Company."
 
    REDEMPTION UPON OCCURRENCE OF A TAX EVENT.
 
   
    At any time following the occurrence of a Tax Event on or after September 3,
2002, even if such Tax Event occurs prior to September 3, 2007, the Company will
have the right to redeem the Series A Preferred Shares and, accordingly, the
Depositary Shares in whole but not in part, subject to the prior written
approval of the Superintendent. The occurrence of a Tax Event will not, however,
give the holders of the Series A Preferred Shares or holders of the Depositary
Shares any right to have such shares redeemed. See "Description of Series A
Preferred Shares--Redemption."
    
 
    AUTOMATIC EXCHANGE UPON OCCURRENCE OF AN EXCHANGE EVENT.
 
   
    Upon the occurrence of an Exchange Event, the outstanding Series A Preferred
Shares will be exchanged automatically on a one-for-one basis for Bank Preferred
Shares. Accordingly, immediately upon the occurrence of an Exchange Event, each
Depositary Share will represent a one-fortieth interest in a
    
 
                                       18
<PAGE>
   
Bank Preferred Share and will no longer represent a fractional interest in a
Series A Preferred Share. See "Description of Series A Preferred
Shares--Automatic Exchange" and "Description of Depositary Shares--Automatic
Exchange." The Automatic Exchange will be a taxable event. Consequently, each
holder of the Series A Preferred Shares will have a gain or loss, as the case
may be, equal to the difference between the basis of such holder in the Series A
Preferred Shares and the fair market value of the Bank Preferred Shares received
in the Automatic Exchange and each holder of the Depositary Shares will have a
gain or loss, as the case may be, equal to the difference between the basis of
such holder in the Depositary Shares and the proportionate fair market value of
Bank Preferred Shares represented by the Depositary Shares at the time of the
Automatic Exchange. See "United States Federal Income Tax Considerations-- Tax
Treatment of Automatic Exchange."
    
 
    CHANGES IN TAX LAW.
 
   
    Under current tax law, payments on the Initial Mortgage Loans and the
Initial Mortgage Assets issued by NB Finance are not subject to any imposition
of withholding tax. There can be no assurance, however, that as a result of any
change in any applicable law, treaty, rule or regulation or any interpretation
thereof, the payments on the Initial Mortgage Loans or the Initial Mortgage
Assets issued by NB Finance might not in the future become subject to
withholding tax. In the event that any withholding tax is imposed on payments of
interest on the Initial Mortgage Loans, neither NB Finance nor the Company will
be entitled to receive additional amounts to compensate for such withholding tax
and, accordingly, such tax would reduce the amount available to make payments on
the Initial Mortgage Assets issued by NB Finance. Consequently, there can be no
assurance that the remaining payments on the Initial Mortgage Assets issued by
NB Finance would be sufficient to make timely payments of dividends on the
Series A Preferred Shares and, accordingly, the Depositary Shares.
    
 
    OWNERSHIP OF THE SERIES A PREFERRED SHARES.
 
    If the possibility of the occurrence of the Automatic Exchange caused the
Bank to be viewed from the date of issuance of the Series A Preferred Shares as
the holder for U.S. federal income tax purposes of the Series A Preferred
Shares, distributions on the Series A Preferred Shares would be subject to
withholding of United States federal income tax at a 30% rate. Consequently, the
Company, as withholding agent, would be liable for the payment of such tax,
which would reduce the amount available to pay dividends on the Series A
Preferred Shares and, accordingly, the Depositary Shares.
 
DIVIDENDS NOT CUMULATIVE
 
    Dividends on the Series A Preferred Shares and, accordingly, the Depositary
Shares, are not cumulative. The Board of Directors may determine, in its
business judgment, that it would be in the best interests of the Company to pay
less than the full amount of the stated dividend on the Series A Preferred
Shares and, accordingly, the Depositary Shares, or no dividend for any quarterly
dividend period, notwithstanding that funds are available to pay such dividend.
Factors that may be considered by the Board of Directors in making this
determination are the Company's financial condition and capital needs, legal or
regulatory requirements, economic conditions and such other factors as the Board
may deem relevant. Consequently, if the Board of Directors does not authorize
and declare a dividend on the Series A Preferred Shares for a quarterly dividend
period, the holders of the Series A Preferred Shares and, accordingly, the
Depositary Shares, would not be entitled to recover such dividend, even if funds
are, or subsequently become, available for payment thereof. Notwithstanding the
foregoing, to remain qualified as a REIT, the Company must distribute annually
at least 95% of its "REIT taxable income" (not including capital gains) to
stockholders. See "--Tax Risks" below and "United States Federal Income Tax
Considerations--Taxation of the Company."
 
DIVIDEND AND OTHER REGULATORY RESTRICTIONS ON OPERATIONS OF THE COMPANY
 
    Because the Company and NB Finance are subsidiaries of the Bank, the
Superintendent has the right to examine the Company and NB Finance and their
respective activities. Under certain circumstances,
 
                                       19
<PAGE>
including any determination that the Bank's relationship with the Company or NB
Finance results in an unsafe and unsound banking practice, the Superintendent
has the authority to restrict the ability of the Company or NB Finance to
transfer assets, to engage in transactions with the Bank, to make distributions
to their stockholders (including dividends to the holders of the Series A
Preferred Shares and, accordingly, the Depositary Shares, as described below) or
to redeem shares of Preferred Stock. The Superintendent could also require the
Bank to sever its relationship with or divest its ownership of the Company.
Consequently, such actions could potentially result in the Company's failure to
pay dividends in respect of the Series A Preferred Shares and, accordingly, the
Depositary Shares or failure to qualify as a REIT, and therefore, result in the
Company being (i) subject to United States income tax in the same manner as a
regular, domestic corporation and (ii) unless entitled to relief, disqualified
from treatment as a REIT for four taxable years following the year during which
such qualification was lost. Failure to qualify as a REIT would not necessarily
give the Company the right to redeem the Series A Preferred Shares or give the
holders thereof the right to have the Series A Preferred Shares redeemed. See
"--Tax Risks." In addition, as subsidiaries of the Bank, the Company and NB
Finance are subject to supervision by U.S. bank regulators.
 
RISK OF FUTURE REVISIONS IN POLICIES AND STRATEGIES BY BOARD OF DIRECTORS
 
    The Board of Directors has established the investment policies and operating
policies and strategies of the Company, certain of which are described in this
Prospectus. These policies may be amended or revised from time to time at the
discretion of the Board of Directors (in certain circumstances subject to the
approval of a majority of the Independent Directors) without a vote of the
Company's stockholders, including holders of the Series A Preferred Shares and,
accordingly, the Depositary Shares. Consequently, holders of the Series A
Preferred Shares and, accordingly, the Depositary Shares cannot preclude the
Board of Directors from revising such policies and strategies and the ultimate
effect of such revision in the policies and strategies of the Company on a
holder of the Series A Preferred Shares and, accordingly, the Depositary Shares
may be negative. See "Business and Strategy--Management Policies and Programs."
 
BALLOON PAYMENTS
 
    The Initial Mortgage Loans do not provide for the complete amortization of
the principal balance thereof over their term to maturity. Accordingly, a
principal payment equal to the original balance of such Initial Mortgage Loan
less any principal payment thereon will be due on each Initial Mortgage Loan at
its maturity date. The ability of the borrower to make a balloon payment
typically will depend upon its ability either to refinance the loan or to sell
the related mortgaged property. In attempting to do so, the borrower will be
affected by a number of factors, including the level of available mortgage rates
at the time of attempted sale or refinancing, the mortgagor's equity in the
mortgaged property, and prevailing economic conditions and the availability of
credit for residential real estate generally. Consequently, Mortgage Loans
requiring balloon payments may involve a greater degree of risk than fully
amortizing loans.
 
NO THIRD PARTY VALUATION OF THE MORTGAGE ASSETS; NO ARM'S-LENGTH NEGOTIATIONS
  WITH AFFILIATES
 
    The Company and the Bank believe that the fair market value of the Initial
Mortgage Assets issued by NB Finance at acquisition was at least equal to the
amount that the Company paid for the Initial Mortgage Assets issued by NB
Finance (approximately US$477 million). However, no third party valuations were
obtained for purposes of the Offering. Consequently, there can be no assurance
that the fair market value of the Initial Mortgage Assets issued by NB Finance
did not differ from the amount that the Company paid for the Initial Mortgage
Assets issued by NB Finance.
 
    In addition, it is not anticipated that any third party valuations will be
obtained in connection with future acquisitions and dispositions of Mortgage
Assets even in circumstances in which an affiliate of the Company is selling
such Mortgage Assets to, or purchasing such Mortgage Assets from, the Company.
Consequently, although the Company and the Bank intend that future acquisitions
or dispositions of Mortgage Assets will be on a fair market value basis, there
can be no assurance that the consideration to be paid (or received) by the
Company to (or from) the Bank or any of its affiliates in connection with
 
                                       20
<PAGE>
future acquisitions or dispositions of Mortgage Assets will not differ from the
fair market value of such Mortgage Assets.
 
RELATIONSHIP WITH THE BANK AND ITS AFFILIATES; CONFLICTS OF INTEREST
 
    The Bank and its affiliates are involved in virtually every aspect of the
Company's existence. The Bank is the sole holder of the Common Stock and
administers the day-to-day activities of the Company under the Advisory
Agreement. The Bank also services Mortgage Loans on behalf of the Company under
the Servicing Agreement. In addition, other than the Independent Directors, all
of the officers and directors of the Company are also officers and/or directors
of the Bank and/or affiliates of the Bank. As the holder of all of the
outstanding voting stock of the Company, the Bank will have the right to elect
all directors of the Company, including the Independent Directors.
 
    The Bank and its affiliates may have interests which are not identical to
those of the Company. Consequently, conflicts of interest may arise with respect
to transactions, including, without limitation, the issuance of the Initial
Mortgage Assets; future acquisitions of Mortgage Assets from the Bank and/or
affiliates of the Bank; servicing of Mortgage Loans (including the Initial
Mortgage Loans); future dispositions of Mortgage Assets to the Bank or
affiliates of the Bank; and the renewal, termination or modification of the
Advisory Agreement or the Servicing Agreement. It is the intention of the
Company and the Bank that any agreements and transactions between the Company,
on the one hand, and the Bank and/or its affiliates, on the other hand, be fair
to all parties and consistent with market terms, including the prices paid and
received for Mortgage Assets or in connection with the servicing of Mortgage
Loans. The requirement in the Company's Charter that certain actions of the
Company be approved by a majority of the Independent Directors is also intended
to ensure fair dealings between the Company and the Bank and its affiliates.
However, there can be no assurance that such agreements or transactions will be
on terms as favorable to the Company as those that could have been obtained from
unaffiliated third parties. See "Business and Strategy--Management Policies and
Programs--Conflict of Interest Policies."
 
DEPENDENCE UPON THE BANK
 
    Pursuant to the Advisory Agreement, the Bank administers the day-to-day
operations of the Company. Pursuant to the Servicing Agreement, the Bank
services the Initial Mortgage Loans on behalf of, and as agent for, the Company.
Consequently, (i) the Company is dependent for the selection, structuring and
monitoring of its Mortgage Assets on the diligence and skill of the officers and
employees of the Bank and (ii) the Company is dependent upon the expertise of
the Bank for the servicing of Mortgage Loans. The Bank may subcontract all or a
portion of its obligations under the Advisory Agreement, and the Bank may
subcontract all or a portion of its obligations under the Servicing Agreement,
to one or more affiliates, and under certain conditions to non-affiliates,
involved in the business of managing Mortgage Assets. Consequently, in the event
the Bank subcontracts its obligations in such a manner, the Company will be
dependent upon the subcontractor to provide services. See "Management--The Bank"
and "Business and Strategy--Servicing."
 
UNREGISTERED SALE AND ASSIGNMENT OF INITIAL MORTGAGE LOANS
 
   
    In order to avoid significant transaction costs, the Company has not and
does not currently intend to register its interest in the Initial Mortgage Loans
in the registry offices where the properties securing the Initial Mortgage Loans
are located. Under Quebec law, such registration formalities are required in
order for the mortgagors under the Initial Mortgage Loans and third parties to
recognize the Company's interest in the Initial Mortgage Loans. Accordingly, if
the Bank were to sell the Initial Mortgage Loans to a bona fide third party
purchaser, in breach of its fiduciary obligations to the Company, such
purchaser's interest in the Initial Mortgage Loans could take priority over that
of the Company. Such purchaser would, however, have to register its interest in
the Initial Mortgage Loans prior to the Company registering its interest
therein. Currently, the Bank continues to be the registered owner of the Initial
Mortgage Loans. The Company can complete the necessary registration formalities
at any time.
    
 
                                       21
<PAGE>
ABSENCE OF PUBLIC MARKET
 
   
    The Company intends to list the Depositary Shares on the NYSE. The Company
is under no obligation, and currently has no intention, to list the Series A
Preferred Shares on a national exchange. There is no existing market for the
Series A Preferred Shares or the Depositary Shares and there can be no assurance
as to the liquidity of any markets that may develop for the Series A Preferred
Shares or the Depositary Shares, the ability of the holders to sell their Series
A Preferred Shares or their Depositary Shares or at what price holders of the
Series A Preferred Shares or the Depositary Shares will be able to sell their
Series A Preferred Shares or their Depositary Shares, respectively. Future
liquidity and trading prices of the Series A Preferred Shares and the Depositary
Shares will depend on many factors including, among other things, prevailing
interest rates, the Company's operating results, the market for similar
securities and, with respect to the Series A Preferred Shares, whether the
Series A Preferred Shares are listed on a national exchange. The Initial
Purchaser has informed the Company that the Initial Purchaser may make a market
in the Series A Preferred Shares. However, the Initial Purchaser is not
obligated to do so and any such market making activity may be terminated at any
time without notice to the holders of the Series A Preferred Shares. In
addition, such market making activity will be subject to the limits of the
Securities Act and may be limited in duration. Consequently, holders of Series A
Preferred Shares and holders of Depositary Shares may find it difficult to sell
their Series A Preferred Shares or their Depositary Shares, respectively, or to
sell their Series A Preferred Shares or their Depositary Shares, respectively,
at a price equivalent to the purchase price thereof.
    
 
RISKS ASSOCIATED WITH THE BANK
 
    AUTOMATIC EXCHANGE.
 
   
    The purchase of Series A Preferred Shares and, accordingly, the Depositary
Shares involves risks to the holder of such shares with respect to the
performance and capital levels of the Bank. An imminent failure to pay dividends
on preferred shares of the Bank when due, a decline in the capital levels of the
Bank or an act of the Superintendent could result in the Series A Preferred
Shares being exchanged automatically for the Bank Preferred Shares. Immediately
upon the occurrence of an Exchange Event, each Depositary Shares will represent
a one-fortieth interest in a Bank Preferred Share and will no longer represent a
fractional interest in a Series A Preferred Share. Consequently, (i) the Bank
Preferred Shares would be an investment in the Bank and not in the Company and
(ii) as a result of an Exchange Event, holders of the Series A Preferred Shares
would be required to exchange their Series A Preferred Shares for Bank Preferred
Shares and become preferred shareholders of the Bank and Depositary Shares will
represent an interest in preferred shares of the Bank at a time when the Bank is
experiencing financial difficulties or its financial condition is deteriorating
or when the Bank has been taken over by the Superintendent or proceedings for
the winding-up of the Bank have been commenced. An Exchange Event includes the
Superintendent electing to cause the Automatic Exchange.
    
 
    INVESTMENT IN THE BANK.
 
    An investment in the Bank is also subject to risks that are distinct from
the risks associated with an investment in the Company, including the general
risks inherent in equity investments in depository institutions. In the event of
a winding-up of the Bank, the claims of depositors and secured, senior, general
and subordinated creditors of the Bank would be entitled to a priority of
payment over the claims of holders of equity interests, such as the Bank
Preferred Shares. Consequently, if the Bank were to be wound up, the holders of
the Series A Preferred Shares likely and, accordingly, Depositary Shares would
receive, if anything, substantially less than they would have received had the
Series A Preferred Shares not been exchanged for and, accordingly, the
Depositary Shares did not represent the Bank Preferred Shares.
 
    DIVIDEND RESTRICTIONS ON BANK PREFERRED SHARES.
 
    If an Exchange Event occurs, the Bank would likely be prohibited from paying
dividends on the Bank Preferred Shares. The Bank's ability to pay dividends on
the Bank Preferred Shares would also be subject
 
                                       22
<PAGE>
to various restrictions under applicable regulations and certain contractual
provisions. In addition, dividends on the Bank Preferred Shares and,
accordingly, Depositary Shares representing Bank Preferred Shares owned by U.S.
investors will generally be subject to Canadian nonresident withholding tax.
Immediately upon the occurrence of an Exchange Event, each Depositary Share will
represent a one-fortieth interest in a Bank Preferred Share and will no longer
represent a fractional interest in a Series A Preferred Share. Consequently, in
the event of an Exchange Event, holders of Series A Preferred Shares
automatically exchanged for Bank Preferred Shares and Depositary Shares
representing Bank Preferred Shares would likely receive no dividends or, in the
alternative, if dividends were paid on the Bank Preferred Shares, holders of
Series A Preferred Shares automatically exchanged for Bank Preferred Shares and
Depositary Shares representing Bank Preferred Shares would become subject to
Canadian nonresident withholding tax. The Bank currently has outstanding three
series of cumulative First Preferred Shares and three series of non-cumulative
First Preferred Shares. The Bank may not, without the approval of the holders of
all such series and any future series, create or issue any shares ranking in
priority to or equally therewith if any cumulative dividends have not been
declared and paid or set aside for payment or any declared and unpaid
non-cumulative dividends have not been paid or set aside for payment.
Immediately prior to any failure by the Bank to declare and pay or set aside for
payment, the Series A Preferred Shares will be automatically exchanged for Bank
Preferred Shares. See "Canadian Federal Income Tax Considerations." Potential
holders of the Series A Preferred Shares should carefully consider the
foregoing.
 
CANADIAN LEGAL CONSIDERATIONS
 
    A mortgagee (referred to in the Province of Quebec as a "hypothecary
creditor") holding a mortgage (referred to in the Province of Quebec as a
"hypothec") on a residential property located in the Province of Quebec may,
when the mortgagor is in default and the mortgagee's claim is due and payable,
take possession of such residential property in payment of its claim or have the
property sold by judicial authority. Such mortgagee must notify the mortgagor at
least 60 days prior to taking any action and register such notice at the
appropriate registry office for the residential property before it may seek any
remedies. If at the time the mortgagee's prior notice is registered the
mortgagor has discharged at least one-half of the obligations secured by the
mortgage, the mortgagee must obtain court authorization prior to exercising its
remedy of taking the property in payment. Subsequent mortgagees or the mortgagor
may, within the 60-day period following the registration of the mortgagee's
notice, require the mortgagee to abandon its remedy of taking the property in
payment and, instead, have the property sold by judicial authority. In order to
exercise this right, a subsequent mortgagee must furnish a bond guaranteeing
that the price at which the property will be sold at a judicial sale will
satisfy in full the prior mortgagee's claim.
 
    Under Quebec law, until a mortgagor is notified of the transfer of the
mortgagee's interest in the mortgage, the mortgagor or any third party,
including a trustee in bankruptcy, may not be bound by such transfer.
Furthermore, until such transfer is registered at the registry office where the
mortgaged property is located, and a certified statement of registration is
furnished to the mortgagor, the transferee's rights may be subject to the
rights, title and interest of a subsequent assignee of the mortgage that has
properly registered its interest therein and notified the mortgagor thereof.
 
    For residential properties outside the Province of Quebec, remedial
proceedings in the nature of foreclosure or sale by power of sale may be taken
to enforce the rights of a mortgagee when a mortgagor is in default, provided
that there has been compliance with the laws of the local jurisdiction.
 
    Most provinces in Canada, including Quebec, have laws, public policy and
general principles of equity relating to the protection of mortgagors.
Consequently, depending on the provisions of the applicable law and the specific
facts and circumstances involved, violations of these laws, policies and
principles may limit the ability of the Company to collect all or part of the
principal of or interest on the Initial Mortgage Loans, may entitle mortgagors
to a refund of amounts previously paid and, in addition, could subject the
Company to damages and administrative sanctions.

                      THE BANK, THE COMPANY AND NB FINANCE
 
THE BANK
 
    The Bank was formed through a series of amalgamations and its roots date
back to 1859 with the founding of the Banque Nationale in Quebec City. The Bank,
which ranks sixth among Canadian banks in terms of total assets, is present in
each of Canada's provinces. It delivers an extensive range of financial services
to individuals, commercial enterprises, financial institutions and governments
both in Canada and abroad. The Bank Preferred Shares, if issued, will be a
series of First Preferred Shares. Additional information regarding the Bank is
included in the Bank's short-form prospectus related to the Bank Preferred
Shares affixed to this Prospectus as Annex A.
 
THE COMPANY
 
    On August 20, 1997, the Company was incorporated under the laws of the State
of Maryland for the purpose of providing U.S. investors with the opportunity to
invest in Canadian residential mortgages and other real estate assets. The
Company began operations on September 3, 1997. The Company's principal business
objective is to acquire, hold, finance and manage Mortgage Assets that will
generate net income for distribution to stockholders. Mortgage Assets are
obligations secured by real property as well as certain other qualifying REIT
assets. The Company's Mortgage Assets currently consist of (i) sixteen
hypothecation loans (the "Initial Mortgage Assets") issued to the Company by NB
Finance that are recourse only to sixteen pools of, at December 31, 1997, 11,692
Mortgage Loans (the "Initial Mortgage Loans") and (ii) cash. Mortgage Loans
consist of CMHC-insured residential first mortgages that are secured by real
property located in Canada. See "Business and Strategy--Description of Initial
Mortgage Assets" and "-- Description of Initial Mortgage Loans." At least 90% of
the Company's Mortgage Assets consist of obligations that are recourse only to
Mortgage Loans and that are secured by real property.
 
    Generally, the Company acquired its Mortgage Assets from the Bank and
affiliates of the Bank. The Company may also from time to time, however, acquire
Mortgage Assets from unrelated third parties. The Bank administers the
day-to-day operations of the Company under the Advisory Agreement. All of the
Common Stock is owned by the Bank. The Company will elect to be taxable as a
REIT under the Code and will generally not be liable for United States federal
income tax to the extent that it distributes its income to its stockholders and
maintains its qualification as a REIT. For a further description of the
operations of the Company, see "Business and Strategy," "Management," "Risk
Factors" and "United States Federal Income Tax Considerations."
 
    The Series A Preferred Shares will be exchanged automatically on a
one-for-one basis for the Bank Preferred Shares upon the occurrence of the
Exchange Event. Immediately upon the occurrence of an Exchange Event, each
Depositary Share will represent a one-fortieth interest in a Bank Preferred
Share and no longer represent a fractional interest in a Series A Preferred
Share. CONSEQUENTLY, HOLDERS OF THE SERIES A PREFERRED SHARES COULD BE REQUIRED
TO EXCHANGE THEIR SERIES A PREFERRED SHARES FOR BANK PREFERRED SHARES AND
HOLDERS OF DEPOSITARY SHARES COULD HOLD A FRACTIONAL INTEREST IN BANK PREFERRED
SHARES, WITHOUT ANY ACTION BY THE HOLDER THEREOF, AT A TIME WHEN THE BANK IS
EXPERIENCING FINANCIAL DIFFICULTIES OR ITS FINANCIAL CONDITION IS DETERIORATING
OR WHEN THE SUPERINTENDENT HAS TAKEN CONTROL OF THE BANK OR PROCEEDINGS FOR THE
WINDING-UP OF THE BANK HAVE BEEN COMMENCED. See "Description of Series A
Preferred Shares--Automatic Exchange."
 
NB FINANCE
 
    On September 3, 1997, NB Finance was incorporated under the laws of Bermuda.
NB Finance was organized solely for the purpose of acquiring Mortgage Loans and
issuing Initial Mortgage Assets, and other similar obligations, to the Company.
Pursuant to the OSFI Order, NB Finance is not permitted to
 
                                       24

activities other than the ownership of Mortgage Loans and activities incidental
thereto.
    
 
                                USE OF PROCEEDS
 
    There will be no proceeds to the Company from the Offering. The Initial
Purchaser will receive the net proceeds from the resale of the Depositary
Shares.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                       OF LIQUIDITY AND CAPITAL RESOURCES
 
THE COMPANY
 
    GENERAL.
 
    The Company was incorporated on August 20, 1997 and is a Maryland
corporation. The Company's principal business objective is to acquire, hold,
finance and manage assets consisting of obligations secured by real property as
well as other qualifying REIT assets. On September 3, 1997, the Company issued
US$300 million of Preferred Stock and, simultaneously, received a capital
contribution from the Bank of US$183 million. The Company used the aggregate net
proceeds of US$477 million to acquire the Initial Mortgage Assets issued by NB
Finance. The Company is under no obligation, and currently has no intention, to
list the Series A Preferred Shares on a national exchange. The Company intends
to list the Depositary Shares on the NYSE. In connection with its organization,
the Company has incurred significant legal and other advisory fees which will
not be recurring.
 
    LIQUIDITY AND CAPITAL RESOURCES.
 
    The Company's principal short-term and long-term liquidity needs are to pay
quarterly dividends on the Series A Preferred Shares and, accordingly, the
Depositary Shares, to pay fees and expenses of the Bank pursuant to the
Servicing Agreement and the Advisory Agreement, and to pay franchise fees and
expenses of advisors, if any, to the Company. The Company does not have any
indebtedness (current or long-term), other material capital expenditures,
balloon payments or other payments due on other long-term obligations. No
negative covenants have been imposed on the Company.
 
    The Company's revenues are derived from its Mortgage Assets. As of December
31, 1997, the US$457 million of Initial Mortgage Assets issued by NB Finance are
over-collateralized by the C$793 million (US$554 million) of Initial Mortgage
Loans. The Company believes that the amounts generated from the payment of
interest and principal on such Initial Mortgage Loans will provide more than
sufficient funds to make full payments with respect to the Initial Mortgage
Assets issued by NB Finance and that such payments will provide the Company with
sufficient funds to meet its operating expenses and to pay quarterly dividends
on the Series A Preferred Shares and, accordingly, the Depositary Shares. To the
extent that the cash flow from its Mortgage Assets exceeds those amounts, the
Company will use the excess to fund the acquisition of additional Mortgage
Assets and make distributions on the Common Stock.
 
    SIGNIFICANT ACCOUNTING POLICY.
 
    The Company's financial statements are prepared in accordance with
accounting principles generally accepted in the United States of America. The
Company has been organized and will elect to be taxable as a REIT under the Code
and, as such, expects to pay an aggregate amount of dividends with respect to
its outstanding shares of stock equal to not less than 100% of its REIT taxable
income, subject to certain adjustments. In order to remain qualified as a REIT,
the Company must distribute annually at least 95% of its REIT taxable income,
subject to certain adjustments. As a REIT, the Company will not generally be
liable for United States federal income tax to the extent it complies with the
foregoing criteria.
 
NB FINANCE
 
    GENERAL.
 
   
    NB Finance was organized on September 3, 1997 under the laws of Bermuda. NB
Finance was organized solely for the purpose of acquiring Mortgage Loans and
issuing the Initial Mortgage Assets, and other similar obligations, to the
Company. Pursuant to the OSFI Order, NB Finance is not permitted to incur any
indebtedness (other than to the Company) or engage in any business activities
other than ownership of Mortgage Loans and activities incidental thereto.
Pursuant to the Loan Agreement, dated
    
 
                                       27
<PAGE>
September 3, 1997, between NB Finance and the Company, NB Finance issued to the
Company the Initial Mortgage Assets for US$477 million. The proceeds from the
issuance of the Initial Mortgage Assets, in addition to a deemed capital
contribution from the Bank, were used to acquire the Initial Mortgage Loans from
the Bank for C$828 million (US$596 million).
 
    LIQUIDITY AND CAPITAL RESOURCES.
 
    NB Finance's principal short-term and long-term liquidity needs are to, with
respect to the Initial Mortgage Assets, pay principal when due (maturity dates
range between January 2000 to January 2011) and monthly interest payments.
Pursuant to the terms of the Mortgage Loan Assignment Agreement, dated September
3, 1997, between the Company, NB Finance and the Bank (the "Mortgage Loan
Assignment Agreement"), NB Finance has assigned its entire right, title and
interest in, to and under the Initial Mortgage Loans to the Company and permits
the Company to administer, perform and enforce the Initial Mortgage Loans.
Pursuant to the Servicing Agreement, the Initial Mortgage Loans are serviced by
the Bank. Accordingly, no interest or principal payments with respect to the
Initial Mortgage Assets are made directly by NB Finance.
 
   
    NB Finance's revenues are derived from its Mortgage Loans. As of December
31, 1997, the US$457 million of Initial Mortgage Assets are over-collateralized
by C$793 million (US$554 million) of the Initial Mortgage Loans. Pursuant to the
Mortgage Loan Assignment Agreement, all payments made in respect of the Initial
Mortgage Loans are made to the Company (through the Bank as servicer under the
Servicing Agreement). Any such amount, if any, in excess of the amount due and
payable on the Initial Mortgage Assets is remitted to NB Finance. Pursuant to
the OSFI Order, NB Finance is not permitted to incur indebtedness (other than to
the Company), nor does it have any other material capital expenditures, balloon
payments or other payments due on long-term obligations. No negative covenants
have been imposed on NB Finance.
    
 
    SIGNIFICANT ACCOUNTING POLICIES.
 
   
    NB Finance's financial statements are prepared in accordance with generally
accepted accounting principles in Canada and are expressed in U.S. dollars. The
preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Although these estimates are based on management's best knowledge of current
events and actions that NB Finance may undertake in the future, actual results
could differ from the estimates. NB Finance is not subject to income tax in
Bermuda.
    
 
   
    The Mortgage Loans are recorded at their principal amounts less allowances
for credit losses. The premium paid on mortgage loans is amortized on a
straight-line basis over a three-year period.
    
 
    Monetary assets and liabilities denominated in foreign currencies are
translated into U.S. dollars at year-end rates of exchange. Revenue and expense
items are translated at rates prevailing at the transaction dates. Gains and
losses resulting from translation are reflected in the statement of income. NB
Finance uses cross currency swaps to manage the currency risk exposure of the
mortgage loans. The gains and losses resulting from the valuation of these
instruments are deferred and amortized to income over the life of the hedged
assets.

                             BUSINESS AND STRATEGY
 
GENERAL
 
    The Company's principal business objective is to acquire, hold, finance and
manage Mortgage Assets that will generate net income for distribution to
stockholders. Mortgage Assets are obligations secured by real property, as well
as certain other qualifying REIT assets. Currently, the Company's Mortgage
Assets consist of (i) sixteen hypothecation loans issued to the Company by NB
Finance (the "Initial Mortgage Assets") that are recourse only to the sixteen
pools of, at December 31, 1997, 11,692 CMHC-insured residential first mortgages
secured by real property located in Canada (the "Initial Mortgage Loans") and
(ii) cash. The Company acquired the Initial Mortgage Assets issued by NB Finance
for an aggregate purchase price of approximately US$477 million. See
"--Description of Initial Mortgage Assets" and "-- Description of Initial
Mortgage Loans."
 
    In order to preserve its status as a REIT under the Code, substantially all
of the assets of the Company consist of the Initial Mortgage Assets issued by NB
Finance and other real estate assets that are of the type set forth in Section
856(c)(6)(B) of the Code. See "United States Federal Income Tax Considerations."
 
    NB Finance was organized solely for the purpose of acquiring Mortgage Loans
and issuing the Initial Mortgage Assets, and other similar obligations, to the
Company. Pursuant to the OSFI Order, NB Finance is not permitted to engage in
any business activity other than ownership of Mortgage Loans and activities
incidental thereto.
 
DESCRIPTION OF THE COMPANY'S DIVIDEND POLICY
 
    Dividends on the Series A Preferred Shares are payable at the rate of 8.35%
per annum of the liquidation preference (an amount equal to US$83.50 per annum
per Series A Preferred Share, calculated by multiplying the annual dividend rate
of 8.35% by the liquidation preference of US$1,000 per share, assuming
authorization and declaration by the Board of Directors of four quarterly
dividends), if, when and as authorized and declared by the Board of Directors.
As of December 31, 1997, the US$457 million of Initial Mortgage Assets issued by
NB Finance are over-collateralized by C$793 million (US$554 million) of Initial
Mortgage Loans. The Company believes that the amounts generated from the payment
of interest and principal on such Initial Mortgage Loans will more than provide
sufficient funds to make full payments with respect to Initial Mortgage Assets
and that such payments will provide the Company with sufficient funds to meet
its operating expenses and to pay quarterly dividends on the Series A Preferred
Shares and, accordingly, the Depositary Shares. In order to remain qualified as
a REIT, the Company must distribute to stockholders annually at least 95% of its
REIT taxable income. The Company expects to pay an aggregate amount of dividends
with respect to its outstanding shares of stock equal to not less than 100% of
the Company's REIT taxable income. The Company anticipates that none of the
dividends on the Series A Preferred Shares and, accordingly, the Depositary
Shares and none or no material portion of the dividends on the Common Stock will
constitute non-taxable returns of capital.
 
    Dividends will be authorized and declared at the discretion of the Board of
Directors after considering the Company's distributable funds and financial
requirements, tax considerations and other factors. There are, however, several
limitations on the Company's ability to pay dividends on the Common Stock (none
of which should adversely affect the legal right of the Company to pay dividends
on the Series A Preferred Shares and, accordingly, the Depositary Shares).
First, under the Company's current dividend policy, the Company may not make any
distribution in respect of the Common Stock to the extent that, after taking
into account such proposed distribution, total cash or property distributions on
the Company's outstanding shares of Preferred Stock and Common Stock in any year
would exceed 105% of the Company's REIT taxable income for that year, plus net
capital gains of the Company for that year. This policy regarding the limitation
on payment of dividends on the Common Stock may not be modified without the
approval of a majority of the Independent Directors. Second, if the Company
fails to authorize and declare and pay the
 
                                       29
<PAGE>
stated dividend on the Series A Preferred Shares in any dividend period, the
Company may not pay any dividends with respect to the Common Stock until such
time as dividends on all outstanding Series A Preferred Shares have been (i)
authorized and declared and paid for three consecutive dividend periods and (ii)
authorized and declared and paid or authorized and declared and a sum sufficient
for the payment thereof set apart for the fourth consecutive dividend period.
See "Description of Series A Preferred Shares--Dividends." Third, the Maryland
General Corporation Law ("MGCL") provides that dividends may be paid on the
stock of a corporation only if, after payment of the distribution, (i) the
corporation would be able to pay its indebtedness as such indebtedness becomes
due in the usual course of business and (ii) the corporation's total assets
would not be less than the sum of its total liabilities plus, unless the
corporation's Charter provides otherwise (which the Charter does), the amount
that would be needed, if the corporation were to be dissolved at the time of the
distribution, to satisfy the preferential rights on dissolution of stockholders
whose rights on dissolution are superior to those receiving the distribution. It
is possible that these limitations on the Company's ability to pay dividends on
the Common Stock could affect the ability of the Company to qualify as a REIT
under the Code. See "United States Federal Income Tax Considerations--Taxation
of the Company."
 
    The Depositary will distribute all cash dividends, other cash distributions
and, in the event of a distribution other than in cash, property (unless the
Depositary determines that it is not feasible to distribute such property, in
which case it may, with the approval of the Company, sell such property and
distribute the net proceeds from such sale) received in respect of the Series A
Preferred Shares to the record holders of Depositary Shares representing such
Series A Preferred Shares in proportion to the number of Depositary Shares owned
by such holder on the relevant record date. See "Description of Depositary
Shares--Dividends."
 
DESCRIPTION OF NB FINANCE'S DIVIDEND POLICY
 
    There are no corporate restrictions on the ability of NB Finance to declare
and pay a dividend to its stockholder in accordance with Bermuda law.
 
DESCRIPTION OF THE COMPANY'S INVESTMENT POLICY
 
    GENERAL.
 
    The Company has formulated the following investment policy. The Company's
current intention is to follow the investment policy as described below.
However, this policy may be amended or revised from time to time at the
discretion of the Board of Directors (in certain circumstances subject to the
approval of a majority of the Independent Directors) without a vote of the
Company's stockholders, including holders of Series A Preferred Shares and,
accordingly, the Depositary Shares. See "Risk Factors--Risk of Future Revision
in Policies and Strategies by the Board of Directors." Accordingly, the
following description of the Company's investment policy includes descriptions
of assets in which the Company does not currently, but may in the future, have
investments. There is no specific policy with respect to the amount or
percentage of assets which will be invested in any specific property. All
investments will be made primarily for income.
 
    The general policy of the Bank with respect to uninsured loans is to lend no
more than 75% of the appraised value of the asset securing such loan.
 
    INITIAL MORTGAGE ASSETS.
 
    Percentage of current portfolio: 95%. The Company's investments currently
consist principally of the Initial Mortgage Assets (i.e., sixteen hypothecation
loans, in the aggregate amount of US$457 million, issued by NB Finance to the
Company) that are recourse only to the Initial Mortgage Loans (i.e., sixteen
pools of CMHC-insured residential first mortgages, in the aggregate amount at
December 31, 1997 of C$793 million (US$554 million) originated by the Bank or
acquired by the Bank from other lenders
 
                                       30
<PAGE>
approved by the National Housing Act (an "NHA-Approved Lender"). The Initial
Mortgage Assets are secured by residential real property located primarily in
Quebec, Ontario and New Brunswick underlying the Initial Mortgage Loans. See
"--Description of the Initial Mortgage Assets."
 
   
    In order to perfect its security interest in the Initial Mortgage Loans, the
Company would need to register the transfer and assignment of each one of the
Initial Mortgage Loans in each land registry or land titles office in Canada
where the real properties securing the Initial Mortgage Loans are located. The
Company would also be required to properly notify each one of the hypothecary
debtors and mortgagors under the Initial Mortgage Loans of the existence of such
transfer and assignment. These procedures could be fulfilled for any specific
mortgage loan comprising the Initial Mortgage Loans or for all of them. The
Company can comply with these procedures at any time and, therefore, has decided
not to currently incur the registration and other fees related to such
procedures.
    
 
    The Servicing Agreement entered into between the Bank and the Company
provides that the Bank, on behalf of the Company, would foreclose on the
properties in accordance with the National Housing Act and normal mortgage
servicing practices of prudent mortgage lending institutions.
 
    The Company's current investment policy is to invest at least 90% of its
portfolio in the Initial Mortgage Assets issued by NB Finance and obligations
that are comparable to the Initial Mortgage Assets. The maturities of the
Initial Mortgage Assets issued by NB Finance range from January 2000 to July
2001. Accordingly, after July 2001, the Company's portfolio will not include any
Initial Mortgage Assets issued by NB Finance.
 
    MORTGAGE LOANS.
 
   
    Percentage of current portfolio: 0%. While no Mortgage Loans are included in
the Initial Mortgage Assets issued by NB Finance, and while the Company has no
current intention to acquire Mortgage Loans, the Company may from time to time
acquire individual residential Mortgage Loans or pools of residential Mortgage
Loans from the Bank or other NHA-Approved Lenders. All Mortgage Loans will
consist of CMHC-insured residential first mortgages and, accordingly, the credit
risk associated therewith should be considerably mitigated. The properties
underlying such Mortgage Loans are expected to be located in Canada. See
"--Description of the Initial Mortgage Loans." Potentially, up to 10% of the
Company's portfolio could be comprised of Mortgage Loans.
    
 
    When a CMHC-insured residential first mortgage is in arrears for more than
90 days or when information has been obtained by the Bank indicating that the
global financial soundness of the borrower has declined, such mortgage may be
transferred to the Bank's collection department. Once transferred, the Bank can
foreclose on the property, legally sell the property or initiate a personal
lawsuit against the borrower. In the event of a foreclosure proceeding, the
property securing such mortgage is offered for sale for 90 days. If during the
90 day period the property is not sold, the CMHC will purchase the property for
the amount of the Company's claims against such property. If the property is
sold during the 90 day period at an amount less than the Company's claim against
such property, a claim is made to CMHC for the amount of the deficiency. The
Company's claim against any such property and, therefore, the amount recoverable
from CMHC, includes interest for a period of twelve months at the loan rate and
for six additional months at the loan rate minus two percent which should offset
any claim processing delays in collection from CMHC. The Company may make a
supplementary claim for expenses and interest thereon within 90 days of the
original claim.
 
    RESIDENTIAL MORTGAGE LOANS.
 
   
    Percentage of current portfolio: 0%. While no residential mortgages are
included in the Initial Mortgage Assets issued by NB Finance, and while the
Company has no current intention to acquire residential mortgages, the Company
may from time to time acquire individual residential mortgages other than
Mortgage Loans ("Residential Mortgage Loans"). These Residential Mortgage Loans
are expected to
    
 
                                       31
<PAGE>
meet the requirements for sale to governmental or private mortgage conduit
programs or other investors in the secondary mortgage market (i.e., such
Residential Mortgages must be rated "A" (or better) by at least one major rating
agency (a Canadian rating agency for Canadian-based mortgages or a U.S. rating
agency for U.S.-based mortgages) or include some form of credit enhancement
(such as over-collateralization, letter of credit or accumulated cash)).
 
    While Mortgage Loans benefit from CMHC insurance, there can be no assurance
that any Residential Mortgage Loans acquired by the Company will be similarly
protected. Some Residential Mortgage Loans are, however, insured by Mortgage
Insurance Company of Canada (now part of GE Capital), therefore considerably
mitigating any credit risk relating to those mortgages. Moreover, large (i.e.,
more than four housing units) residential uninsured mortgage loans sold to the
Company must have, as of the time of a sale, a "credit score" of the Bank of
five or better. The Bank has an internal credit scoring system whereby the risk
of large residential loans is ranked from one (the least risk) to ten (the most
risk) according to different factors such as the cash flow derived from the
mortgaged property. Potentially, up to 10% of the Company's portfolio could be
comprised of Residential Mortgage Loans.
 
    Mortgage Insurance Company of Canada is a private insurer owned by GE
Capital Canada. The insurance premium is paid by the borrower and may be added
to the principal of the mortgage loan. The premium rates vary in accordance with
the principal amount of the loan. Generally, the greater the loan to value
ratio, the greater the premium rate.
 
    MORTGAGE-BACKED SECURITIES.
 
   
    Percentage of current portfolio: 0%. While no Mortgage-Backed Securities are
included in the Initial Mortgage Assets issued by NB Finance, and while the
Company has no current intention to acquire Mortgage-Backed Securities, the
Company may from time to time acquire fixed-rate or variable-rate
Mortgage-Backed Securities representing interests in pools of mortgage loans
such as an NHA Mortgage-Backed Security ("NHA MBS") that evidences an undivided
interest in a pool of first mortgages originated by certain approved financial
institutions in Canada and insured by CMHC. There are four different types of
NHA MBS pools. The "exclusive homeowner" pools are classified as prepayable
because the borrowers within this type of pool have the option to prepay their
mortgage (often at a penalty) in accordance with the specific terms of the
mortgage. Depending upon the specific exclusive homeowner pool, the appropriate
penalty may or may not be passed through to the investors. The "mixed" pools are
comprised of a combination of homeowner, multiple family or social housing
mortgages. The "multi-family" pools are comprised exclusively of multiple family
loans and are generally not prepayable. Also, there is a special category of NHA
MBS pool created to allow exclusive pools of "social housing mortgages"
(mortgages issued to finance low-cost housing for senior citizens, the disabled
and economically disadvantaged). The key feature of social housing pools is the
absence of prepayment at the option of the borrower on the underlying mortgages;
this makes them more attractive to investors who seek predictable cash flow. A
portion of any NHA MBS that the Company purchases may have been originated by
the Bank by exchanging pools of Mortgage Loans for the Mortgage-Backed
Securities. The Company does not intend to acquire any interest-only,
principal-only or similar speculative Mortgage-Backed Securities. Potentially,
up to 10% of the Company's portfolio could be comprised of Mortgage-Backed
Securities. Additionally, the Company could potentially acquire all of the
Mortgage-Backed Securities of any one issuer; provided that such acquisition
does not exceed 10% of the Company portfolio.
    
 
    Timely payment of both principal and interest on NHA MBSs is unconditionally
guaranteed by CMHC. In the event the Company were to buy non-NHA MBSs, the
investment policies of the Company would require such MBSs to be rated "A" (or
better) by at least one major rating agency (a Canadian rating agency for
Canadian-based mortgages or a U.S. rating agency for U.S.-based mortgages), and
the underlying mortgages would be required to be first lien mortgages.
 
                                       32
<PAGE>
    In general, the risk associated with investments in Mortgage-Backed
Securities are credit risk and prepayment risk. Credit risk refers to the risk
of not receiving either principal or interest payments. In the case of an NHA
MBS, credit risk is not an issue since CMHC unconditionally guarantees timely
payment of both principal and interest. For a non-NHA MBS, credit risk is
strongly mitigated by the fact that the Company can, pursuant to its current
investment policy, only buy "A" (or better) rated instruments. In general, a
non-NHA MBS rated "A" or better are credit enhanced by over-collateralization, a
letter of credit, an initial deposit into a cash collateral account or the
presence of one or more subordinated classes. Prepayment risk is the risk of
receiving unscheduled principal payments while the Mortgage-Backed Security is
worth more than par. For example, a sale will usually trigger a prepayment. More
importantly for investors, prepayments are motivated by a decline in interest
rates. In Canada, however, prepayment risk is mitigated by two factors: (a)
lenders usually charge prepayment penalties, thereby reducing the incentive to
prepay and (b) almost all mortgages are relatively short-term (typically, 6
month to 5 years) balloon mortgages, also reducing the impact of prepayments.
 
    COMMERCIAL MORTGAGE LOANS.
 
   
    Percentage of current portfolio: 0%. While no Commercial Mortgage Loans are
included in the Initial Mortgage Assets issued by NB Finance, and while the
Company has no current intention to acquire any Commercial Mortgage Loans, the
Company may from time to time acquire Commercial Mortgage Loans secured by
industrial and warehouse properties, recreational facilities, office buildings,
retail space and shopping malls, hotels and motels, nursing homes or senior
living centers. The Company's current policy is not to acquire any interest in a
Commercial Mortgage Loan if Commercial Mortgage Loans would constitute more than
5% of the total book value of the Company's Mortgage Assets immediately
following such acquisition. Also, Commercial Mortgage Loans sold to the Company
must have a Bank (as of the time of the sale) credit score of five or better.
See "--Residential Mortgage Loans." Unlike Mortgage Loans and Residential
Mortgage Loans, Commercial Mortgage Loans generally lack standardized terms.
Commercial Mortgage Loans may also not be fully amortizing, meaning that they
may have a significant principal balance or "balloon" payment due on maturity.
Moreover, commercial properties, particularly industrial and warehouse
properties, are generally subject to relatively greater environmental risks than
non-commercial properties, generally giving rise to increased costs of
compliance with environmental laws and regulations. There is no requirement
regarding the percentage of any commercial real estate property that must be
leased at the time the Company acquires a Commercial Mortgage Loan secured by
such commercial real estate property, and there is no requirement that
Commercial Mortgage Loans have third party guarantees.
    
 
    Commercial Mortgage Loans will not be CMHC insured and the credit quality of
a Commercial Mortgage Loan may depend on, among other factors, the existence and
structure of underlying leases, the physical condition of the property
(including whether any maintenance has been deferred), the creditworthiness of
tenants, the historical and anticipated level of vacancies and rents on the
property and on other comparable properties located in the same region,
potential or existing environmental risks, the availability of credit to
refinance Commercial Mortgage Loans at or prior to maturity and the local and
regional economic climate in general. Foreclosures of defaulted Commercial
Mortgage Loans are generally subject to a number of complicating factors,
including environmental considerations, which are generally not present in
foreclosures of Residential Mortgage Loans. Potentially, up to 5% of the
Company's portfolio could be comprised of Commercial Mortgage Loans.
 
    PARTNERSHIP INTERESTS.
 
   
    Percentage of current portfolio: 0%. While no partnership interests are
included in the Initial Mortgage Assets issued by NB Finance, and while the
Company has no current intention to acquire any partnership interests, the
Company may from time to time acquire limited partnership interests in
partnerships the only activities of which are the purchase and ownership of
Mortgage Loans ("Partnership
    
 
                                       33
<PAGE>
Interests") that are comparable to the Initial Mortgage Loans (i.e., government
insured residential first mortgages). The ability to invest in Partnership
Interests allows the Company to acquire Partnership Interests that in effect
function as conduits for Mortgage Loans, as an alternative to acquiring a direct
interest in such Mortgage Loans. Any Partnership Interests would be economically
comparable to an investment in Mortgage Loans. The limitations imposed by the
REIT rules on the ownership of Partnership Interests are the same as those
imposed on the ownership of Mortgage Loans. Potentially, up to 10% of the
Company's portfolio could be comprised of Partnership Interests.
 
    OTHER ASSETS.
 
   
    Percentage of current portfolio: 5%. The Company may invest up to 10% of the
total value of its portfolio in assets eligible to be held by REITs other than
those described above. Assets eligible to be held by REITs include, and
therefore the Company's portfolio could include, cash, cash equivalents,
government securities and shares or interests in other REITs. The Company's
investments currently include cash generated from operations and not yet
distributed to stockholders. Cash, cash equivalents and government securities
would be expected to be relatively low risk investments. However, the return on
investment related thereto would also be expected to be relatively low. The
Company expects that any investment in shares or interests in other REITs would
be made in REITs holding assets similar to the Initial Mortgage Loans.
Accordingly, the expected risks and return related to such an investment would
be similar to the risks and returns related to the Initial Mortgage Assets and
Initial Mortgage Loans.
    
 
DESCRIPTION OF NB FINANCE'S INVESTMENT POLICY
 
    Pursuant to the OSFI Order, NB Finance is not permitted to engage in any
activity other than ownership of Mortgage Loans and activities incidental
thereto. NB Finance does not have a formal investment policy.
 
DESCRIPTION OF THE COMPANY'S MANAGEMENT POLICIES
 
    GENERAL.
 
    In administering the Company's Mortgage Assets, the Bank, as advisor
pursuant to the Advisory Agreement, has a high degree of autonomy. The Board of
Directors has, however, adopted certain policies to guide the Company and the
Bank with respect to the acquisition and disposition of assets, use of capital
and leverage, credit risk management and certain other activities. These
policies, which are discussed below, may be amended or revised from time to time
at the discretion of the Board of Directors (in certain circumstances subject to
the approval of a majority of the Independent Directors) without a vote of the
Company's stockholders, including holders of the Series A Preferred Shares and,
accordingly, the Depositary Shares. See also "--Dividend Policy"; "Risk
Factors--Risk of Future Revisions in Policies and Strategies by Board of
Directors."
 
    ASSET ACQUISITION AND DISPOSITION POLICIES.
 
    The Company may, from time to time, use payments of interest and principal
in respect of its Mortgage Assets to purchase additional Mortgage Assets (which
are essentially loans to other persons secured by real property) and may also
purchase additional Mortgage Assets out of the proceeds from the issuance, and
not by direct issuance, of additional shares of Preferred Stock or the
contribution of additional capital by the Bank; provided, however, that (i) to
the extent that the investment of such payments or proceeds occurs prior to the
consummation of the Exchange Offer, such payments or proceeds will be invested
in Canadian or U.S. government guaranteed, mortgage-backed certificates and
other Canadian or U.S. government obligations which will be purchased on the
open market or from entities unaffiliated with the Bank or the Company or banks
that are not affiliated with the Bank and (ii) in the event that the Series A
Preferred Shares are not treated as "publicly-offered securities" as of the date
 
                                       34
<PAGE>
on which the Offering and the Exchange Offer are consummated, then during the
period commencing on such date and ending on the date on which the Series A
Preferred Shares become "publicly-offered securities," any investment by the
Company in any Mortgage Assets in a transaction with the Bank and/or affiliates
of the Bank will be made only upon the decision of the Independent Fiduciary.
The Company has acquired all or substantially all of such Mortgage Assets from
the Bank and/or affiliates of the Bank, on terms that are comparable to those
that could be obtained by the Company if such Mortgage Assets were purchased
from unrelated third parties. The Company may also from time to time, however,
acquire Mortgage Assets from unrelated third parties. As of the date of this
Prospectus, the Company has not entered into any agreements with any third
parties with respect to the purchase of Mortgage Assets. Other than with respect
to the temporary investment of payments of interest and principal on its
Mortgage Assets, the Company anticipates that it would purchase Mortgage Assets
from unrelated third parties only if neither the Bank nor any affiliate of the
Bank had an amount or type of Mortgage Assets sufficient to meet the
requirements of the Company.
 
    At least 90% of the Company's portfolio will consist of the Initial Mortgage
Assets issued by NB Finance and obligations which are comparable to the Initial
Mortgage Assets. The Company may, however, invest in other assets eligible to be
held by REITs. See "--Description of the Company's Investment Policy." The
Company's current policy prohibits the acquisition of an interest in any
Mortgage Loan (other than an interest resulting from the acquisition of
Mortgage-Backed Securities or a Partnership Interest) which is delinquent in the
payment of principal or interest at the time of the proposed acquisition.
 
    CAPITAL AND LEVERAGE POLICIES.
 
    To the extent that the Board of Directors determines that additional funding
is required, the Company may raise such funds through additional equity
offerings, or retention of cash flow (after consideration of the provisions of
the Code requiring the distribution by a REIT of a certain percentage of its
income annually and taking into account taxes that would be imposed on the
Company's undistributed taxable income), or a combination of these methods. The
Company will have no debt outstanding following consummation of the Offering and
has no intention of incurring any indebtedness in the future.
 
    In order to qualify as a REIT, the capital stock of the Company must be held
by at least 100 holders during approximately 90% or more of the taxable year
beginning in the Company's second taxable year and each subsequent taxable year.
See "United States Federal Income Tax Considerations--Stock Ownership Tests."
The Company has issued Senior Preferred Shares with an aggregate liquidation
preference of up to US$450,000 and limited transferability to ensure that it
meets, and will continue to meet, the 100 person ownership requirement for REIT
status without having to constantly monitor the number of holders of Preferred
Shares. Except for such Senior Preferred Shares, the Company may not, pursuant
to its Charter, issue additional shares of Preferred Stock senior to the Series
A Preferred Shares either in the payment of dividends or in the distribution of
assets in liquidation, without the consent of holders of at least two-thirds of
the outstanding shares of Preferred Stock at that time, including the Series A
Preferred Shares and Depositary Shares representing Series A Preferred Shares,
and the Company may not issue additional shares of Preferred Stock on a parity
with the Series A Preferred Shares either in the payment of dividends or in the
distribution of assets in liquidation without the approval of a majority of the
Independent Directors. The Company does not currently intend to issue any
additional series of Preferred Stock unless it simultaneously receives
additional capital contributions from the Bank equal to the sum of 59% of the
aggregate offering price of such additional Preferred Stock and the Company's
expenses in connection with the issuance of such additional shares of Preferred
Stock. Prior to its issuance of additional shares of Preferred Stock, the
Company will take into consideration the Bank's regulatory capital requirements
and the cost of raising and maintaining that capital at the time.
 
                                       35
<PAGE>
    CREDIT RISK MANAGEMENT POLICIES.
 
    The Company intends that each Mortgage Loan, if any, acquired from the Bank
an affiliate of the Bank or an unrelated third party in the future will
represent a first lien position, will be covered by valid CMHC insurance and
will be originated in the ordinary course of the originator's real estate
lending activities based on the underwriting standards generally applied (at the
time of origination) for the originator's own account. The Company also expects
that all Mortgage Loans held by the Company directly or indirectly will be
serviced pursuant to the Servicing Agreement, or a similar agreement which
requires servicing in conformity with accepted secondary market standards, with
any servicing guidelines promulgated by the Company and with relevant government
agency guidelines and procedures.
 
    CONFLICT OF INTEREST POLICIES.
 
    Because of the nature of the Company's relationship with the Bank and its
affiliates, it is likely that conflicts of interest will arise with respect to
certain transactions, including, without limitation, the Company's acquisition
of Mortgage Assets from, or disposition of Mortgage Assets to, the Bank or its
affiliates and the renewal, termination or modification of the Advisory
Agreement or the Servicing Agreement. It is the Company's policy that the terms
of any dealings with the Bank and its affiliates will be consistent with those
available from third parties. In addition, neither the Advisory Agreement nor
the Servicing Agreement may be renewed, terminated or modified by the Company
without the approval of a majority of the Independent Directors.
 
    Conflicts of interest between the Company and the Bank and its affiliates
may also arise in connection with making decisions that bear upon the credit
arrangements that the Bank or one of its affiliates may have with a borrower.
Conflicts could also arise in connection with actions taken by the Bank as a
controlling stockholder in the Company. It is the intention of the Company and
the Bank that any agreements and transactions between the Company, on the one
hand, and the Bank or its affiliates, on the other hand, including, without
limitation, the Servicing Agreement, be fair to all parties and consistent with
market terms for such types of transactions. The Servicing Agreement provides
that foreclosures and dispositions in connection with Mortgage Loans will be
performed with a view toward maximizing the recovery by the Company of amounts
due on its Mortgage Assets and the Bank will be required to service Mortgage
Loans solely with a view toward the interests of the Company, and without regard
to the interests of the Bank or any of its other affiliates. The requirement in
the terms of the Series A Preferred Shares that certain actions of the Company
be approved by a majority of the Independent Directors is also intended to
ensure fair dealings between the Company and the Bank and its affiliates.
However, there can be no assurance that any such dealings will be on terms as
favorable to the Company as would have been obtained from unaffiliated third
parties.
 
    There are no provisions in the Charter limiting any officer, director,
security holder or affiliate of the Company from having any direct or indirect
pecuniary interest in any Mortgage Asset to be acquired or disposed of by the
Company or in any transaction in which the Company has an interest or from
engaging in acquiring, holding and managing Mortgage Assets. As described
herein, the Bank and its affiliates have direct interests in transactions with
the Company (including, without limitation, the issuance of Mortgage Assets to
the Company); however, none of the officers or directors of the Company will
have any interests in such Mortgage Assets.
 
    OTHER POLICIES.
 
    The Company operates in a manner that will not subject it to regulation
under the Investment Company Act of 1940, as amended, including by investing
primarily in mortgages and other interests in and liens on real estate.
 
    The Company intends to distribute to stockholders and, accordingly, holders
of Depositary Shares annual reports containing financial statements prepared in
accordance with generally accepted accounting
 
                                       36
<PAGE>
principles and certified by the Company's independent public accountants. The
Charter provides that following the consummation of the Offering and the
Exchange Offer the Company shall maintain its status as a reporting company
under the Exchange Act, for as long as any of the Series A Preferred Shares are
outstanding.
 
    The Company currently has no intention to (a) invest in securities of other
issuers for the purpose of exercising control or (b) underwrite securities of
other issuers. The Company intends, and has the ability, to hold the Mortgage
Assets and the underlying Mortgage Loans until maturity. Although the Company
has no current intention to do so, the Company may, pursuant to the terms of its
Charter, redeem the Preferred Shares. See "Description of the Series A Preferred
Shares--Redemption."
 
    In the event of a redemption of the Series A Preferred Shares underlying the
Depositary Shares, the Depositary Shares will be redeemed from the proceeds
received by the Depositary as a result of such redemption of the Series A
Preferred Shares. If less than all Depositary Shares are to be redeemed, the
Depositary Shares to be redeemed will be selected by lot or pro rata. See
"Description of Depositary Shares--Redemption of Depositary Shares."
 
   
    The Company intends to make investments and operate its business at all
times in such a manner as to comply with the requirements of the Code to qualify
as a REIT. However, future economic, market, legal, tax or other considerations
may cause the Board of Directors, subject to approval by a majority of the
Independent Directors, to determine that it is in the best interests of the
Company and its stockholders to revoke the Company's REIT status.
    
 
    The Bylaws of the Company provide that any director or officer, employee or
agent of the Company, in its personal capacity or in a capacity as an affiliate,
employee, or agent of any other person, or otherwise, may have business
interests and engage in business activities similar to or in addition to or in
competition with those of or relating to the Company. The Company does not
currently have a formal policy with respect to any officer, director, security
holder or affiliate of the Company having any direct or indirect pecuniary
interest in any investment to be acquired or disposed of by the Company or any
of its subsidiaries or in any transaction to which the Company or any of its
subsidiaries is a party or has an interest.
 
DESCRIPTION OF NB FINANCE'S MANAGEMENT POLICIES
 
    GENERAL.
 
   
    NB Finance was organized solely for the purpose of acquiring Mortgage Loans
and issuing the Initial Mortgage Assets, and other similar obligations, to the
Company. Pursuant to the OSFI Order, NB Finance is not permitted to incur any
indebtedness (other than to the Company) or engage in any business activities
other than the ownership of Mortgage Loans and activities incidental thereto.
    
 
    ASSET ACQUISITION AND DISPOSITION POLICIES.
 
   
    NB Finance may, from time to time, use amounts remitted to NB Finance by the
Company, or contributions of additional capital by the Bank, to purchase
additional Mortgage Loans. NB Finance has acquired, and in the future expects to
acquire, all or substantially all of such Mortgage Loans from the Bank and/or
affiliates of the Bank on terms comparable to those that could be obtained by NB
Finance if such Mortgage Loans were purchased from unrelated third parties. As

DESCRIPTION OF THE INITIAL MORTGAGE ASSETS
 
    The Initial Mortgage Assets issued by NB Finance are comprised of sixteen
hypothecation loans issued by NB Finance to the Company. As of December 31,
1997, the principal amount of the Initial Mortgage Assets issued by NB Finance
was approximately US$457 million. Each of the sixteen hypothecation loans
comprising the Initial Mortgage Assets issued by NB Finance is secured by a pool
of Mortgage Loans. As of December 31, 1997, the Initial Mortgage Loans were
comprised of, in the aggregate, 11,692 Mortgage Loans in an aggregate amount of
approximately C$793 million (US$554 million). The value of each pool of Mortgage
Loans comprising the Initial Mortgage Loans exceeds the principal amount of the
hypothecation loan that it secures. Accordingly, the Initial Mortgage Assets
issued by NB Finance are over-collateralized by the Initial Mortgage Loans. The
aggregate amount of the over-collateralization is, as of December 31, 1997,
US$97 million. The Company acquired the Initial Mortgage Assets issued by NB
Finance pursuant to the terms of a loan agreement with NB Finance.
 
   
    Each Initial Mortgage Asset issued by NB Finance is recourse only to the
Initial Mortgage Loans securing such Initial Mortgage Asset. Each pool of
Initial Mortgage Loans is comprised of between 130 and 2,493 CMHC-insured
residential first mortgages. See "Description of the Initial Mortgage Loans."
Each Initial Mortgage Asset issued by NB Finance is further secured by the
residential real properties underlying such CMHC-insured first mortgages. Such
residential real properties are located primarily in Quebec, Ontario and New
Brunswick. The Initial Mortgage Loans are insured. Accordingly, there is
unlikely to be any loss of principal or interest. However, CMHC insurance does
not guarantee timely payment of interest and principal. See "Risk
Factors--Limited Recourse Nature of Certain Mortgage Assets; Limitation on CMHC
Insurance." The Initial Mortgage Assets have maturities ranging from January
2000 to July 2001. The Initial Mortgage Assets pay interest at rates ranging
from 6.90% to 9.77%, with an average rate of approximately 8.40% per annum.

    Payments of interest are made monthly out of payments on the Initial
Mortgage Loans. Pursuant to an agreement between the Company and NB Finance (the
"Mortgage Loan Assignment Agreement"), dated September 3, 1997, the Company
receives all scheduled payments made on the Initial Mortgage Loans, retains a
portion of any such payments equal to the amount due and payable on the Initial
Mortgage Assets issued by NB Finance and remits the balance, if any, to NB
Finance. The Company also retains a portion of any prepayments of principal in
respect of the Initial Mortgage Loans equal to the proportion of such
prepayments that the outstanding principal amount of the Initial Mortgage Loans
bears to the outstanding principal amount of the Initial Mortgage Assets issued
by NB Finance, which amount would be applied to reduce the outstanding principal
amount of the Initial Mortgage Assets issued by NB Finance. Repayment of the
Initial Mortgage Assets issued by NB Finance is secured by an assignment of the
Initial Mortgage Loans to the Company pursuant to the Mortgage Loan Assignment
Agreement, which is governed by the laws of Bermuda. The assignment of the
Initial Mortgage Loans by NB Finance to the Company is without recourse. The
Company has a security interest in the real property securing the Initial
Mortgage Loans and, subject to fulfilling certain procedural requirements under
applicable Canadian law, is entitled to enforce payment on the Initial Mortgage
Loans in its own name if a mortgagor should default thereon. In the event of
such a default, the Company has the same rights as NB Finance to force a sale of
the mortgaged property and satisfy the obligations of NB Finance out of the
proceeds. In the event of a default in respect of an Initial Mortgage Loan, the
amount of the Initial Mortgage Assets issued by NB Finance will be reduced by an
amount equal to the portion thereof allocable to defaulting mortgage. The
Initial Mortgage Loans are administered by the Bank, as servicer pursuant to the
Servicing Agreement, and the Company has the right to perfect its security
interest in the Initial Mortgage Loans by notice and registration. Following
repayment of the Initial Mortgage Assets issued by NB Finance, the Company will
reassign any outstanding Initial Mortgage Loans (without recourse) and deliver
them to, or as directed by,
 
                                       39
<PAGE>
NB Finance. All payments in respect of the Initial Mortgage Loans are made in
Canadian dollars. The amounts due on the Initial Mortgage Assets issued by NB
Finance are retained by the Company free and clear of and without withholding or
deduction for or on account of any present or future taxes imposed by or on
behalf of Bermuda or any political subdivision thereof or therein.
 
    With respect to its underwriting policies, the Bank will not make any
residential mortgage loans that exceed a loan to value ratio of 75% unless such
loan is insured. If the residential mortgage loan is CMHC-insured (i) a cash
down payment of between 5% and 24.9% is required, (ii) the monthly payment for
capital, interest, taxes and heating must not exceed 32% of the gross monthly
revenue of the borrower and (iii) the monthly payment for capital, interest,
taxes, heating and all other monthly payments (including, without limitation,
personal loans, lease payments and credit card debt service) must not exceed 40%
of the net monthly revenue of the borrower. Additionally, for all mortgage
loans, an external credit check must be positive. When a loan is insured, an
additional amount may be added to the principal amount of the mortgage loan
representing the premium related thereto. The premium rates vary in accordance
with the principal amount of the loan. Generally, the greater the loan to value
ratio, the greater the premium rate.
 
    From 1992 through 1997, the Bank's annual loss experience for residential
mortgage loans ranged from a low of approximately C$208,000 on a loan volume of
approximately C$2.325 billion, or 0.0089%, in 1992 to a high of approximately
C$1.425 million on a loan volume of approximately C$6.415 billion, or 0.0222%,
in 1995, with an average annual loss during that period of approximately
C$689,000 on an average annual loan volume of approximately C$5.171 billion, or
0.0133%.
 
    On the last day of the Bank's fiscal year in each of 1993 through 1997, the
Bank's delinquency experience for CMHC-insured residential mortgage loans ranged
from, in the 30 to 59 day category, 727 (0.97%) to 1,641 (1.72%) loans with a
principal and interest delinquent amount of approximately C$46.3 million (1.01%)
to approximately C$126.4 million (1.95%), respectively, in the 60 to 89 day
category, 283 (0.38%) to 607 (0.65%) loans with a principal and interest
delinquent amount of approximately C$19.5 million (0.43%) to approximately
C$43.7 million (0.72%), respectively, in the 90 day or more category, 736
(0.98%) to 1,594 (1.71%) loans with a principal and interest delinquent amount
of approximately C$59.7 million (1.31%) to approximately C$125.8 million
(2.08%), respectively. Percentages are based upon total CMHC-insured residential
mortgage loans originated by the Bank and total principal and interest due
thereon.
 
DESCRIPTION OF THE INITIAL MORTGAGE LOANS
 
    Information with respect to the Initial Mortgage Loans is presented as of
December 31, 1997.
 
    The detailed information set forth in this Prospectus with respect to the
Initial Mortgage Loans applies only to the mortgages purchased by NB Finance.
 
    The Initial Mortgage Loans consist of sixteen pools of residential first
mortgages originated by the Bank or acquired by the Bank from other CMHC
approved lenders. Each pool consists of between 130 and 2,493 CMHC-insured
residential first mortgages and is secured by the underlying residential real
properties located in Canada. Approximately 95% of such properties are located
in the provinces of Quebec, Ontario and New Brunswick. The remaining 5% of such
property is located throughout the remaining Canadian provinces. See "Risk
Factors--All of the Real Property Securing the Initial Mortgage Assets is
Located Outside of the United States." As of December 31, 1997, 11,692
CMHC-insured residential first mortgages comprise the sixteen pools. Generally,
the CMHC-insured residential first mortgages comprising any individual pool are
less than C$100,000. Accordingly, no individual CMHC-insured residential first
mortgage is material to the Company, its operation or its business.
 
    Payments on the Initial Mortgage Loans are due monthly in arrears on the 1st
day of each month through July 2001 or such earlier date on which payment in
full of the Initial Mortgage Loans is made (the
 
                                       40
<PAGE>
"Final Payment Date") or, if the 1st day of a month is not a business day, on
the first business day following the 1st day of such month (a "Monthly Payment
Date"). Payments of interest and principal on the Initial Mortgage Loans are
made in Canadian dollars.
 
    The Initial Mortgage Loans mature monthly beginning in 1999 and bear
interest at rates ranging from approximately 6.0% to 8.99% with an average
interest rate of 7.53% per annum. The Final Payment Date may occur at an earlier
date if final payment on the Initial Mortgage Loans occurs earlier than such
date, because of unscheduled prepayments.
 
    The following table summarizes the Initial Mortgage Loans as of December 31,
1997:

    All of the Initial Mortgage Loans were originated in accordance with
underwriting policies customarily employed by the Bank, or with underwriting
policies acceptable to the Bank. As is generally the case in the Canadian
residential mortgage business, the Bank's underwriting policies are derived from
CMHC approved underwriting criteria, and they focus on the borrower's ability to
repay the mortgage loan and the adequacy of the proposed security.
 
    As a CMHC approved lender, the Bank has access to the National Housing Act
(NHA) mortgage insurance program. All of the Initial Mortgage Loans are insured
by CMHC pursuant to that program. The bulk of those loans were insured at
origination. Whether a loan is insured at origination or through the CMHC
portfolio insurance program, the insurance is valid until the expiration of the
loan.
 
    All of the Initial Mortgage Loans are balloon mortgages. Accordingly, the
Initial Mortgage Loans do not provide for the amortization of the principal
balance thereof over their term to maturity and a principal payment equal to the
original balance less any principal amount previously paid will be due on each
Initial Mortgage Loan at maturity. Mortgage Loans that require a balloon payment
typically involve a greater degree of risk than fully amortizing loans. See
"Risk Factors--Balloon Payments." Balloon mortgages are the most prevalent type
of mortgage offered by Canadian mortgage lenders. At the expiration of the term,
the mortgage is generally renewed, based on then current market conditions, for
a new term. Although the Bank offers terms varying from 3 months to 10 years,
terms exceeding 5 years are relatively rare. Moreover, although the Bank offers
monthly, semi-monthly and weekly pay mortgages, all of the Initial Mortgage
Loans are monthly pay mortgages. In general, loans are amortized over a period
not exceeding 25 years.
 
    The Initial Mortgage Loans provide for limited prepayment rights. For
example, typically up to 10% of the original principal amount of an Initial
Mortgage Loan may be prepaid once annually without penalty. Moreover, an Initial
Mortgage Loan may also be prepaid without penalty if the mortgaged property is
sold and the mortgagor enters into a new mortgage with the same terms and
conditions as the Initial Mortgage Loan. In most other circumstances,
prepayments or renegotiations of either the interest rate or the term of an
Initial Mortgage Loan will be subjected to prepayment penalties. During the
first three years following the most recent interest adjustment date, such
penalties are tantamount to a yield maintenance clause. After three years, such
penalties will be limited to three months of interest.
 
   
    On the date of purchase, the Initial Mortgage Loans had an aggregate
principal amount of approximately C$828 million (US$596 million) and a fair
market value of approximately C$848 million (US$610 million). The Initial
Mortgage Loans mature monthly beginning in 1999, with an average maturity of
approximately September 2000.
    
 
    The Company intends and has the ability to hold the Mortgage Loans to
maturity unless there is a prepayment by the customer or a Mortgage Loan is
impaired. Therefore the Mortgage Loans will be recorded as a long-term
investment in the balance sheet of the Company.
 
EFFECT OF INTEREST RATE FLUCTUATION ON ASSETS AND EARNINGS
 
    It is anticipated that the Company's income will consist principally of
interest payments from the Initial Mortgage Assets issued by NB Finance and
obligations that are comparable to the Initial Mortgage Assets issued by NB
Finance. Interest and principal amounts generated by the Initial Mortgage Loans
and other assets acquired pursuant to the Company's investment policy enable
full payment with respect to the Initial Mortgage Assets issued by NB Finance.
The Initial Mortgage Assets issued by NB Finance and the Initial Mortgage Loans
mature between January 2000 and July 2001.
 
    If there is a significant decline in interest rates at a time when the
Company must reinvest payments of interest and principal in respect of its
Mortgage Assets or Mortgage Loans, the Company may find it difficult to purchase
additional Mortgage Assets or Mortgage Loans which generate sufficient income to
support the payment of dividends on the Series A Preferred Shares and,
accordingly, the Depositary
 
                                       45
<PAGE>
Shares. Because the rate at which dividends on the Series A Preferred Shares,
if, when and as authorized and declared, are payable is fixed, there can be no
assurance that an interest rate environment in which there is a significant
decline in interest rates would not adversely affect the Company's ability to
pay dividends on the Series A Preferred Shares and, accordingly, the Depositary
Shares. Further, it is possible that a significant decline in interest rates
could effect a prepayment of Mortgage Loans. Assuming all Mortgage Loans provide
similar limitations on prepayments as the Initial Mortgage Loans, the effect on
earnings will be, to a certain extent, mitigated. However, such prepayments
could adversely affect the Company's assets.
 
    A significant increase in interest rates would not be expected to adversely
affect the assets or the earnings of the Company.
 
SERVICING
 
    The Initial Mortgage Loans, and certain other Mortgage Loans, are serviced
by the Bank pursuant to the terms of the Servicing Agreement. The Bank receives
a fee equal to 0.25% per annum on the principal balances of the loans serviced.
Payment of such fees is subordinated to payments of dividends on the Series A
Preferred Shares and, accordingly, the Depositary Shares.
 
    The Servicing Agreement requires the Bank to service Mortgage Loans in a
manner generally consistent with normal mortgage servicing practices of prudent
mortgage lending institutions which service mortgage loans of the same type as
the Mortgage Loans, with any servicing guidelines promulgated by the Company and
with relevant government agency guidelines and procedures. The Servicing
Agreement requires the Bank to service Mortgage Loans solely with a view toward
the interests of the Company and without regard to the interests of the Bank or
any of its other affiliates (including NB Finance). The Bank collects and remits
principal and interest payments, administers mortgage escrow accounts, submits
and pursues mortgage insurance claims and supervises foreclosure proceedings on
any Mortgage Loans it services. The Bank also provides accounting and reporting
services with respect to such Mortgage Loans. The Servicing Agreement requires
the Bank to follow such collection procedures as are customary in normal
mortgage servicing practices of prudent mortgage lending institutions which
service mortgage loans of the same type as the Mortgage Loans. The Bank has
substantial experience in the practices followed on behalf of the Company
pursuant to the Servicing Agreement, having employed similar or identical
practices for its own mortgage financing activities. Additional information
regarding the Bank is included in the Bank's short-form prospectus related to
the Bank Preferred Shares affixed to this Prospectus as Annex A. The Bank may
from time to time subcontract all or a portion of its servicing obligations
under the Servicing Agreement to a third party subject to the prior written
approval of the Company. The Bank will not, in connection with subcontracting
any of its obligations under the Servicing Agreement, be discharged or relieved
in any respect from its obligation to the Company to perform its obligations
under the Servicing Agreement. As of the date of this Prospectus, the Bank has
not subcontracted any of its obligations under the Servicing Agreement.
 
    The Bank is required to pay all expenses related to the performance of its
duties under the Servicing Agreement. The Bank is required to make advances of
taxes and required insurance premiums that are not collected from mortgagors
with respect to any Mortgage Loan serviced by it, unless it determines that such
advances are nonrecoverable from the mortgagor, insurance proceeds or other
sources with respect to such Mortgage Loan. If such advances are made, the Bank
generally will be reimbursed prior to the Company being reimbursed out of the
payments with respect to such Mortgage Loan. The Bank also is entitled to
reimbursement for expenses incurred by it in connection with the liquidation of
defaulted Mortgage Loans serviced by it and in connection with the restoration
of mortgaged property. The Bank is responsible to the Company for any loss
suffered as a result of the Bank's failure to make and pursue timely claims or
as a result of actions taken or omissions made by the Bank which cause the
policies to be cancelled by the insurer. Subject to approval by the Company, the
Bank may institute foreclosure proceedings, exercise any power of sale contained
in any Mortgage Loan or deed of trust, obtain a deed in lieu of foreclosure or
 
                                       46
<PAGE>
otherwise acquire title to a mortgaged property underlying a Mortgage Loan by
operation of law or otherwise in accordance with the terms of the Servicing
Agreement. The Bank does not, however, have the authority to conclude contracts
in the name of the Company.
 
    The Company may terminate the Servicing Agreement upon the occurrence of one
or more events specified in the Servicing Agreement. Such events relate
generally to the Bank's proper and timely performance of its duties and
obligations under the Servicing Agreement. In addition, the Company may also
terminate the Servicing Agreement without cause upon 60 days' notice and payment
of a termination fee equal to the product of 0.0002% of the then current
aggregate unpaid principal balance of the Mortgage Loans and the number of
months remaining until the first anniversary of the Servicing Agreement. The
termination fee will be based on the aggregate outstanding principal amount of
the Mortgage Loans then serviced under the Servicing Agreement. As long as any
of the Series A Preferred Shares remain outstanding, the Company may not renew,
terminate, or modify the Servicing Agreement without the approval of a majority
of the Independent Directors.
 
    As is customary in the mortgage loan servicing industry, the Bank is
entitled to retain any late payment charges, penalties and assumption fees
collected in connection with the Mortgage Loans serviced by it. The Bank will
receive any benefit derived from interest earned on collected principal and
interest payments between the date of collection and the date of remittance to
the Company and, to the extent permitted by law, from interest earned on tax and
insurance impound funds with respect to Mortgage Loans serviced by it.
 
    When any mortgaged property underlying a Mortgage Loan is conveyed by a
mortgagor, the Bank generally will enforce any "due-on-sale" clause contained in
the Mortgage Loan, to the extent permitted under applicable law and governmental
regulations. The terms of a particular Mortgage Loan or applicable law, however,
may provide that the Bank is prohibited from exercising the "due-on-sale" clause
under certain circumstances related to the security underlying the Mortgage Loan
and the buyer's ability to fulfill the obligations thereunder. Upon any
assumption of a Mortgage Loan by a transferee, a nominal fee is typically
required, which sum will be retained by the Bank as additional servicing
compensation.
 
EMPLOYEES
 
    The Company and NB Finance have six and no employees, respectively.
Information regarding the executive officers of the Company and NB Finance is
provided below under "Management--Directors and Executive Officers--The Company"
and "--NB Finance." Neither the Company nor NB Finance anticipates that it will
require any additional employees because (i) the Company retains the Bank to
perform certain functions pursuant to the Advisory Agreement as described below
under "Management--The Bank" and (ii) pursuant to the OSFI Order, NB Finance is
not permitted to engage in any business activities other than the ownership of
Mortgage Loans and activities incidental thereto. Each employee of the Company
and NB Finance is currently also an officer and/or director of the Bank and/or
affiliates of the Bank. The Company and NB Finance maintain corporate records
and audited financial statements that are separate from those of the Bank and of
any of the Bank's affiliates.
 
COMPETITION
 
    The Company does not engage in the business of originating Mortgage Assets.
While the Company will purchase additional Mortgage Assets, it anticipates that
such Mortgage Assets will be purchased from the Bank and/or affiliates of the
Bank. Accordingly, the Company does not compete with mortgage conduit programs,
investment banking firms, savings and loan associations, banks, thrift and loan
associations, finance companies, mortgage bankers or insurance companies in
acquiring its Mortgage Assets.
 
    NB Finance does not engage in the business of originating Mortgage Loans.
While NB Finance may purchase additional Mortgage Loans, it anticipates that
such Mortgage Loans will be purchased from the Bank and/or affiliates of the
Bank. Accordingly, NB Finance does not compete with savings and loan
 
                                       47
<PAGE>
associations, banks, thrift and loan associations, finance companies, mortgage
bankers or insurance companies in acquiring Mortgage Loans.
 
    As of October 31, 1997, the Bank held more than C$13 billion of residential
mortgage assets. Slightly more than 70% of such mortgages were located in
Quebec, the Bank's principal place of business. The major competitor of the Bank
in Quebec is the Caisses Populaires Desjardins (a credit union). The market
share of the Bank for such mortgages in Quebec is approximately 18% compared
with a significantly greater market share for Caisses Populaires Desjardins.
 
LEGAL PROCEEDINGS
 
    Neither the Company nor NB Finance is the subject of any material
litigation. None of the Company, NB Finance or any other affiliate of the Bank
is currently involved in nor, to the Company's knowledge, currently threatened
with any material litigation with respect to the Initial Mortgage Assets issued
by NB Finance or the Initial Mortgage Loans, other than routine litigation
arising in the ordinary course of business, most of which is expected to be
covered by liability insurance.

    The above table illustrates the estimated annual retirement benefit payable
on a straight line annuity basis to participating employees at normal retirement
age (generally age 60), in the earnings and years of service classifications
indicated, under the defined benefit pension plan sponsored by the Bank (the
"Bank Pension Plan") and an excess benefit plan which covers certain employees
of the Bank and its subsidiaries. For each year of service credited to a
participant in the Bank Pension Plan, a participant will be entitled to 2% of
his or her annual eligible earnings, less the amount earned under the Canada or
Quebec pension plans while participating in the Bank Pension Plan. Annual
eligible earnings is defined as a participant's average earnings for such
participant's 60 highest-paid consecutive months, based on salary and 25% of
bonus. Mr. Smock had accrued 16.4 years of credited service under the Bank
Pension Plan as of his resignation. Mr. Ouellet had accrued 17.5 years of
credited service under the Bank Pension Plan as of December 31, 1997.
 
    In addition to the Bank Pension Plan, certain employees of the Bank and its
subsidiaries, including those of the Company, may also participate in an excess
benefit plan for participants in the Bank Pension Plan whose benefits are
reduced pursuant to limitations on pensions imposed by the Income Tax Act
(Canada). Employees covered by the excess benefit plan receive a benefit equal
to the amount of benefit disallowed under the Pension Plan due to such
limitations.

INDEPENDENT DIRECTORS
 
    The terms of the Series A Preferred Shares require that, as long as any
Series A Preferred Shares are outstanding, certain actions by the Company must
be approved by a majority of the Independent Directors. See "Description of
Series A Preferred Shares--Independent Director Approval." Mr. Hanley and Mr.
Michel are Independent Directors. As long as there are only two Independent
Directors, any action that requires the approval of a majority of Independent
Directors must be approved by both the Independent Directors.
 
    If at any time the Company fails to declare and pay a quarterly dividend on
the Series A Preferred Shares, the number of directors then constituting the
Board of Directors will be increased by at least two at the Company's next
annual meeting and the holders of the Series A Preferred Shares, voting together
as a single class with the holders of Depositary Shares representing Series A
Preferred Shares and the holders of any other outstanding series of Preferred
Stock entitled to vote on the matter, including the Senior Preferred Shares,
will be entitled to elect two additional directors to serve on the Board of
Directors. Any member of the Board of Directors elected by holders of Preferred
Stock and holders of Depositary Shares representing Series A Preferred Shares
will be deemed to be an Independent Director for purposes of the actions
requiring the approval of a majority of the Independent Directors. The Company
expects that the Bank will elect a majority of the Board of Directors. See
"Description of Series A Preferred Shares-- Voting Rights."
 
AUDIT COMMITTEE
 
    The Board of Directors of the Company will establish an audit committee that
will review the engagement of independent accountants and their independence.
The audit committee will also review the adequacy of the Company's internal
accounting controls. The audit committee will be comprised of Mr. Hanley and Mr.
Michel.
 
    The Bye-laws of NB Finance provide the Board of Directors with the authority
to establish committees. As of the date of this Prospectus, no such committees
have been established by the Board of Directors.
 
COMPENSATION OF INDEPENDENT DIRECTORS
 
    The Company pays its Independent Directors fees for their services as
directors. Each Independent Director receives annual compensation of $10,000
plus a fee of $750 for attendance (in person or by telephone) at each meeting of
the Board of Directors.
 
    NB Finance does not directly pay its Independent Directors any fees for
their services as directors. Codan Services Limited has been engaged by NB
Finance to provide administrative services to NB Finance, including the services
of NB Finance's Independent Directors. Codan Services Limited receives an annual
fee of US$4,500 for such services.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The MGCL permits a Maryland corporation to include in its charter a
provision limiting the liability of the corporation's directors and officers to
the corporation and its stockholders for money damages except for liability
resulting from (a) actual receipt of an improper benefit or profit in money,
property or services or (b) active and deliberate dishonesty established by a
final judgment as being material to the cause of action. The Charter contains
such a provision which eliminates such liability to the maximum extent permitted
by the MGCL.
 
    The Charter authorizes the Company, to the maximum extent permitted by
Maryland law, to obligate itself to indemnify and to pay or reimburse reasonable
expenses in advance of final disposition of a proceeding to (a) any present or
former director or officer or (b) any individual who, while a director of
 
                                       53
<PAGE>
the Company and at the request of the Company, serves or has served another
corporation, partnership, joint venture, trust, employee benefit plan or any
other enterprise as a director, officer, partner or trustee of such corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
from and against any claim or liability to which such person may become subject
or which such person may incur by reason of his or her status as a present or
former director or officer of the Company. The Bylaws of the Company obligate
it, to the maximum extent permitted by Maryland law, to indemnify and to pay or
reimburse reasonable expenses in advance of final disposition of a proceeding to
(a) any present or former director or officer who is made a party to the
proceeding by reason of his service in that capacity or (b) any individual who,
while a director of the Company and at the request of the Company, serves or has
served another corporation, partnership, joint venture, trust, employee benefit
plan or any other enterprise as a director, officer, partner or trustee of such
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise and who is made a party to the proceeding by reason of his service in
that capacity. The Charter and Bylaws also permit the Company to indemnify and
advance expenses to any person who served a predecessor of the Company in any of
the capacities described above and to any employee or agent of the Company or a
predecessor of the Company.
 
    The MGCL requires a corporation (unless its charter provides otherwise,
which the Charter does not) to indemnify a director or officer who has been
successful, on the merits or otherwise, in the defense of any proceeding to
which he is made a party by reason of his service in that capacity. The MGCL
permits a corporation to indemnify its present and former directors and
officers, among others, against judgments, penalties, fines, settlements and
reasonable expenses actually incurred by them in connection with any proceeding
to which they may be made a party by reason of their service in those or other
capacities unless it is established that (a) the act or omission of the director
or officer was material to the matter giving rise to the proceeding and (i) was
committed in bad faith or (ii) was the result of active and deliberate
dishonesty, (b) the director or officer actually received an improper personal
benefit in money, property or services or (c) in the case of any criminal
proceeding, the director or officer had reasonable cause to believe that the act
or omission was unlawful. However, under the MGCL, a Maryland corporation may
not indemnify for an adverse judgment in a suit by or in the right of the
corporation or for a judgment of liability on the basis that personal benefit
was improperly received, unless in either case a court orders indemnification
and then only for expenses. In addition, the MGCL requires the Company, as a
condition to advancing expenses, to obtain (a) a written affirmation by the
director or officer of his good faith belief that he has met the standard of
conduct necessary for indemnification by the Company and (b) a written statement
by or on his behalf to repay the amount paid or reimbursed by the Company if it
shall ultimately be determined that the standard of conduct was not met.
 
    The Bye-laws of NB Finance provide that the directors, secretary and other
officers (such term to include, for the purposes of indemnification, any person
appointed to a committee by the Board of Directors), for the time each was
acting on behalf of NB Finance, shall be indemnified from and against all
actions, costs, charges, losses, damages and expenses which they or any of them,
their heirs, executors or administrators, shall incur as a result of any actions
or omissions in the execution of their duties. The foregoing indemnity does not
apply to acts of fraud or dishonesty. Pursuant to a letter dated February 27,
1998, the Bank has undertaken to indemnify the Independent Directors of NB
Finance for any liability incurred in connection with the good faith performance
of their duties as directors, which liability arises as a result of a material
misstatement or omission in the registration statements filed with the
Commission in connection with the Offering and the Exchange Offer.
 
THE BANK AS ADVISOR
 
    The Company entered into the Advisory Agreement with the Bank to administer
the day-to-day operations of the Company. The Bank is responsible for (i)
monitoring the credit quality of Mortgage Assets held by the Company, (ii)
advising the Company with respect to the reinvestment of income from and
payments on, and with respect to the acquisition, management, financing and
disposition of, Mortgage
 
                                       54
<PAGE>
Assets held by the Company, (iii) holding documents relating to the Company's
Mortgage Assets as custodian, (iv) monitoring the Company's compliance with the
requirements necessary to qualify as a REIT and (v) maintaining its status as a
NHA Approved Lender. The Bank may, with the approval of a majority of the Board
of Directors as well as a majority of the Independent Directors, subcontract all
or a portion of its obligations under the Advisory Agreement to one or more
related or unrelated third parties. The Bank will not, in connection with the
subcontracting of any of its obligations under the Advisory Agreement, be
discharged or relieved in any respect from its obligations under the Advisory
Agreement. As of the date of this Prospectus, the Bank has not subcontracted any
of its obligations under the Advisory Agreement.
 
    The Bank and its affiliates have substantial experience in mortgage finance
and in the administration of Mortgage Assets. Additional information regarding
the Bank is included in the Bank's short-form prospectus related to the Bank
Preferred Shares affixed to this Prospectus as Annex A.
 
    The Advisory Agreement has an initial term of one year, and may be renewed
for additional one-year periods. The Advisory Agreement may be terminated by the
Company at any time upon 60 days' prior written notice. As long as any of the
Series A Preferred Shares remain outstanding, any decision by the Company to
renew, terminate or modify the Advisory Agreement must be approved by a majority
of the Board of Directors, as well as by a majority of the Independent
Directors. The Bank is entitled to receive an advisory fee equal to US$25,000
payable in equal quarterly installments with respect to the advisory and
management services provided by it to the Company. Payment of such fees is
subordinated to payments of dividends on the Series A Preferred Shares and,
accordingly, the Depositary Shares.
 
    As a result of the relationship between the Bank and the Company, certain
conflicts of interest may arise. See "Risk Factors--Relationship with the Bank
and its Affiliates; Conflicts of Interest." In addition, under certain
circumstances, The Independent Fiduciary will exercise the discretionary
authority reserved to the Company with respect to transactions involving both
the Company and the Bank or any Bank affiliate. See "ERISA Considerations."

                        DESCRIPTION OF DEPOSITARY SHARES
 
    Set forth below are the material provisions of the Deposit Agreement, the
Depositary Shares and Depositary Receipts. See the form of Deposit Agreement and
form of Depositary Receipt which are filed as an exhibit to the Registration
Statement of which this Prospectus is a part.
 
GENERAL
 
    Each Depositary Share represents a one-fortieth interest in a Series A
Preferred Share. The Series A Preferred Shares underlying the Depositary Shares
will be deposited with The Bank of Nova Scotia Trust Company of New York, as
Depositary (the "Depositary"), under a Deposit Agreement (the "Deposit
Agreement"), among the Company, the Bank, the Depositary and all holders, from
time to time, of depositary receipts issued by the Depositary thereunder (the
"Depositary Receipts"). The Company intends to list the Depositary Shares, and
expects that the Depositary Shares will be approved for listing, on the NYSE.
The Company does not plan to list the Series A Preferred Shares on any national
exchange. Accordingly, the Company does not expect that there will be any public
trading market for the Series A Preferred Shares except as represented by the
Depositary Shares. The Depositary Shares will be evidenced by Depositary
Receipts.
 
    Subject to the terms of the Deposit Agreement, each owner of a Depositary
Share will be entitled through the Depositary, in proportion to the one-fortieth
interest in a Series A Preferred Share underlying such Depositary Share, to all
the rights, preferences and privileges of a Series A Preferred Share (including
dividend, voting, redemption and liquidation rights), and will be subject to all
of the limitations of the fractional share of Series A Preferred Shares
represented thereby. See "Description of Series A Preferred Shares." Since each
Series A Preferred Share entitles the holder thereof to one vote on matters on
which the Series A Preferred Shares are entitled to vote, each Depositary Share
will, in effect, entitle the holder thereof to one-fortieth of a vote thereon,
rather than one full vote. See "Description of Series A Preferred Shares--Voting
Rights."
 
    The Depositary will act as transfer agent and registrar and paying agent
with respect to the Depositary Shares.
 
    After the date fixed for redemption (which will be the same date as any
redemption date for the Series A Preferred Shares), the Depositary Shares so
called for redemption will no longer be deemed to be outstanding and all rights
of the holders of the Depositary Shares will cease, except the right to receive
the moneys payable upon such redemption and any money or other property to which
the holders of such Depositary Shares were entitled upon such redemption upon
surrender to the Depositary of the Depositary Receipts evidencing such
Depositary Shares.
 
VOTING RIGHTS
 
    Upon receipt of notice of any meeting at which the holders of the Series A
Preferred Shares are entitled to vote, the Depositary will mail the information
contained in such notice of meeting to the record holders of the Depositary
Shares representing the Series A Preferred Shares. Each record holder of such
Depositary Shares on the record date (which will be the same date as the record
date for the Series A Preferred Shares) will be entitled to instruct the
Depositary as to the exercise of the voting rights pertaining to the number of
whole Series A Preferred Shares underlying such holder's Depositary Shares. The
Depositary will endeavor, insofar as practicable, to vote the number of whole
Series A Preferred Shares underlying such Depositary Shares in accordance with
such instructions, and the Company and the Bank will agree to take all action
that may be deemed necessary by the Depositary in order to enable the Depositary
to do so. The Depositary will abstain from voting the Series A Preferred Shares
to the extent the Depositary does not receive specific instructions from the
holders of Depositary Shares relating to such shares.
 
                                       56
<PAGE>
AMENDMENT OF THE DEPOSIT AGREEMENT
 
    The form of Depositary Receipt evidencing the Depositary Shares and any
provision of the Deposit Agreement may at any time be amended by agreement
between the Company, the Bank and the Depositary. However, any amendment which
imposes or increases any fees, taxes or other charges upon holders of Depositary
Receipts (other than taxes and other governmental charges, fees, and other
expenses payable by such holders as stated under "Charges of Depositary"), or
which otherwise materially and adversely alters the rights of holders of
Depositary Shares will not take effect unless such amendment has been approved
by the holders of at least a majority of the Depositary Shares then outstanding.
 
CHARGES OF DEPOSITARY
 
   
    Holders of Depositary Shares will not pay any transfer or other taxes or
governmental charges that arise solely from the existence of the depositary
arrangements. The Initial Purchaser will pay the charges of the Depositary in
connection with the initial deposit of the Series A Preferred Shares, any
redemption of the Series A Preferred Shares and all other charges, fees and
expenses provided for in the Deposit Agreement. Holders of Depositary Shares
will pay all other transfer and other taxes and governmental charges, and, in
addition, such other charges, if any, as are expressly provided in the Deposit
Agreement to be for their accounts.
    
 
MISCELLANEOUS
 
    The Depositary will forward to the holders of Depositary Shares all reports
and communications from the Company which the Company is required to furnish to
the holders of the Series A Preferred Shares.
 
    The Depositary, the Company and the Bank will not be liable if it is
prevented or delayed by law or any circumstances beyond its control in
performing its obligations under the Deposit Agreement. Except as a result of
negligence or willful misconduct in performance of their respective duties under
the Deposit Agreement, the obligations of the Company, the Bank and the
Depositary under the Deposit Agreement will be limited to performance in their
best judgment and in good faith of their duties thereunder and they will not be
obligated to prosecute or defend any legal proceedings in respect of any
Depositary Shares or Series A Preferred Shares unless satisfactory indemnity is
furnished. The Company, the Bank and the Depositary may rely upon written advice
of counsel or accountants, or information provided by persons presenting Series
A Preferred Shares for deposit, holders of Depositary Shares or other persons
believed to be competent and on documents believed to be genuine.
 
RESIGNATION AND REMOVAL OF DEPOSITARY; TERMINATION OF THE DEPOSIT AGREEMENT
 
    The Depositary may resign at any time by delivering to the Company notice of
its election to do so, and the Company may at any time remove the Depositary,
any such resignation or removal to take effect upon the appointment of a
successor Depositary and its acceptance of such appointment. Such successor
Depositary will be appointed by the Company within 60 days after delivery of the
notice of resignation or removal.
 
    The Deposit Agreement may be terminated at the direction of the Company or
the Bank or by the Depositary if a period of 60 days shall have expired after
the Depositary has delivered to the Company written notice of its election to
resign and a successor Depositary shall have not been appointed. Upon
termination of the Deposit Agreement, the Depositary will discontinue the
transfer of Depositary Receipts, will suspend the distribution of dividends to
the holders thereof, and will not give any further notices (other than notice of
such termination) or perform any further acts under the Deposit Agreement except
that the Depositary will continue to collect dividends pertaining to the Series
A Preferred Shares and deliver, upon surrender of Depositary Receipts held by
such holder, certificates representing Series A Preferred Shares together with
any dividends or other distributions received with respect thereto and the
proceeds of the sale of any rights or property. At any time after the expiration
of one year from the date of termination, the Depositary may sell the Series A
Preferred Shares and hold the proceeds of such sale, without interest, for the
benefit of the holders of Receipts who have not then surrendered their
Depositary
 
                                       57
<PAGE>
Receipts. After making such sale, the Depositary will be discharged from all
obligations under the Deposit Agreement except to account for such proceeds.
 
    The Deposit Agreement will automatically terminate if there has been a final
distribution in respect of Series A Preferred Shares in connection with any
liquidation, dissolution or winding-up of the Company and such distribution has
been distributed to holders of Depositary Receipts.
 
ISSUANCE OF DEPOSITARY RECEIPTS AND WITHDRAWAL OF SERIES A PREFERRED SHARES FROM
  DEPOSIT
 
    The Initial Purchaser and any other holder of Series A Preferred Shares who
exchanges Series A Preferred Shares pursuant to the Exchange Offer may deposit
Series A Preferred Shares with the Depositary, which will then issue and deliver
the Depositary Receipts to the purchasers of the Series A Preferred Shares.
Holders of Series A Preferred Shares other than the Initial Purchaser who do not
tender their Series A Preferred Shares into the Exchange Offer will be precluded
from depositing their Series A Preferred Shares with the Depositary until such
time as the applicable holding period with respect to such Series A Preferred
Shares has expired and such Series A Preferred Shares have become freely
transferable. Depositary Receipts will be issued evidencing only whole
Depositary Shares.
 
    Upon surrender of Depositary Receipts at the corporate office of the
Depositary (or other such office as the Depositary may designate), the owner of
the Depositary Shares evidenced thereby is entitled at such office to
certificates evidencing the number of Series A Preferred Shares (but only in
whole Series A Preferred Shares) represented by such Depositary Receipts. If the
Depositary Receipts delivered by the holder evidence a number of Depositary
Shares in excess of the number of whole Series A Preferred Shares to be
withdrawn, the Depositary will deliver to such holder at the same time a new
Depositary Receipt evidencing such excess number of Depositary Shares.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
    The Depositary will distribute all cash dividends or other cash
distributions received in respect of the Series A Preferred Shares to the record
holders of Depositary Shares representing such Series A Preferred Shares in
proportion to the numbers of such Depositary Shares owned by such holders on the
relevant record date. In the event of a distribution other than in cash, the
Depositary will distribute property received by it to the record holders of
Depositary Shares entitled thereto, unless the Depositary determines that it is
not feasible to make such distribution, in which case the Depositary may, with
the approval of the Company, sell such property and distribute the net proceeds
from such sale to such holders.
 
REDEMPTION OF DEPOSITARY SHARES
 
    If the Series A Preferred Shares underlying the Depositary Shares are
subject to redemption, the Depositary Shares will be redeemed from the proceeds
received by the Depositary resulting from the redemption, in whole or in part,
of such Series A Preferred Shares held by the Depositary. The redemption price
per Depositary Share will be equal to the applicable fraction of the redemption
price per share payable with respect to such Series A Preferred Shares. If less
than all Depositary Shares are to be redeemed, the Depositary Shares to be
redeemed will be selected by lot or pro rata.
 
AUTOMATIC EXCHANGE
 
    Immediately upon the occurrence of an Exchange Event, each Depositary Share
will represent a one-fortieth interest in a Bank Preferred Share and will no
longer represent a fractional interest in a Series A Preferred Share.
 
TAXATION
 
   
    Owners of the Depositary Shares will be treated for United States federal
income tax purposes as if they were owners of the Series A Preferred Shares
represented by the Depositary Shares and, accordingly, must take into account
for United States federal income tax purposes any dividends on the Series A
Preferred Shares represented by the Depositary Shares and any gain or loss on
the sale or exchange of the Series A Preferred Shares represented by Depositary
Shares.

                  DESCRIPTION OF THE SERIES A PREFERRED SHARES
 
    The following summary of the material terms and provisions of the Series A
Preferred Shares does not purport to be complete and is qualified in its
entirety by reference to Maryland law and to the terms and provisions of the
Charter establishing the Series A Preferred Shares and the other provisions of
the Charter, a copy of which is available from the Company upon request. See
"Description of Capital Stock."
 
GENERAL
 
    The Series A Preferred Shares form a series of Preferred Stock, which
Preferred Stock may be issued from time to time in one or more series with such
designations, preferences, conversion or other rights, voting powers,
restrictions, limitations as to dividends or other distributions, qualifications
and terms and conditions of redemption as are determined by the Board of
Directors. The Board of Directors has authorized the Company to issue the Series
A Preferred Shares.
 
    The Series A Preferred Shares are validly issued, fully paid and
nonassessable. The holders of the Series A Preferred Shares have no preemptive
rights with respect to any shares of the stock of the Company or any other
securities of the Company convertible into or carrying rights or options to
purchase any such shares. The Series A Preferred Shares are perpetual and will
not be convertible into shares of Common Stock or any other class or series of
stock of the Company and will not be subject to any sinking fund or other
obligation of the Company for their repurchase or retirement. The Series A
Preferred Shares will be exchanged automatically on a one-for-one basis for the
Bank Preferred Shares upon the occurrence of an Exchange Event.
 
    The transfer agent, registrar and dividend disbursement agent for the Series
A Preferred Shares will be The Bank of Nova Scotia Trust Company of New York.
The registrar for shares of Series A Preferred Shares will send notices to
shareholders of any meetings at which holders of the Series A Preferred Shares
have the right to elect directors of the Company or to vote on any other matter.
 
DIVIDENDS
 
    Holders of the Series A Preferred Shares shall be entitled to receive, if,
when and as authorized and declared by the Board of Directors out of assets of
the Company legally available therefor, noncumulative cash dividends at the rate
of 8.35% per annum of the liquidation preference (equivalent to US$83.50 per
share per annum, calculated by multiplying the annual dividend rate of 8.35% by
the liquidation preference of US$1,000 per share, assuming authorization and
declaration by the Board of Directors of four quarterly dividends). If
authorized and declared, dividends on the Series A Preferred Shares shall be
payable quarterly in arrears on the 30th day of March, June, September and
December (or, if any such day is not a business day, on the next business day)
of each year, at such annual rate, commencing December 30, 1997. Dividends in
each quarterly dividend period will accrue from the first day of such period,
whether or not authorized, declared or paid for the prior quarterly period. Each
authorized and declared dividend shall be payable to holders of record as they
appear at the close of business on the stock register of the Company on such
record dates, not exceeding 45 calendar days nor less than 10 calendar days
preceding the payment dates thereof, as shall be fixed by the Board of
Directors. Dividends payable on the Series A Preferred Shares for any dividend
period greater or less than a full dividend period shall be computed on the
basis of twelve 30-day months, a 360-day year and the actual number of days
elapsed in the period; provided, however, that in the event of the Automatic
Exchange, any accrued and unpaid dividends on the Series A Preferred Shares as
of the Time of Exchange (as defined) shall be deemed to be accrued and unpaid
dividends on the Bank Preferred Shares.
 
    The right of holders of the Series A Preferred Shares to receive dividends
is noncumulative. Accordingly, if the Board of Directors fails to authorize or
declare a dividend on the Series A Preferred
 
                                       59
<PAGE>
Shares for a quarterly dividend period, then holders of the Series A Preferred
Shares will have no right to receive a dividend for that period, and the Company
will have no obligation to pay a dividend for that period, whether or not
dividends are authorized and declared and paid for any future period with
respect to either the Preferred Stock or the Common Stock authorized. If the
Company fails to pay or authorize and set aside for payment a quarterly dividend
on the Series A Preferred Shares, holders of Preferred Stock, including the
Series A Preferred Shares and the Senior Preferred Shares, will be entitled to
elect two directors. See "--Voting Rights."
 
    If full dividends on the Series A Preferred Shares for any dividend period
shall not have been authorized, declared and paid, or authorized, declared and a
sum sufficient for the payment thereof set apart for such payments, no dividends
shall be authorized, declared or paid or set aside for payment with respect to
the Common Stock or any other stock of the Company ranking junior to or on a
parity with the Series A Preferred Shares as to dividends or amounts upon
liquidation, nor shall any Common Stock or any other capital stock of the
Company ranking junior to or on a parity with the Series A Preferred Shares as
to dividends or amounts upon liquidation be redeemed, purchased or otherwise
acquired for any consideration (or any monies to be paid to or made available
for a sinking fund for the redemption of any such stock) by the Company (except
by conversion into or exchange for other stock of the Company ranking junior to
the Series A Preferred Shares as to dividends and amounts upon liquidation),
until such time as dividends on all outstanding Series A Preferred Shares have
been (i) authorized, declared and paid for three consecutive dividend periods
and (ii) authorized, declared and paid or authorized, declared and a sum
sufficient for the payment thereof has been set apart for payment for the fourth
consecutive dividend period.
 
    When dividends are not paid in full (or a sum sufficient for such full
payment is not set apart) upon the Series A Preferred Shares and the shares of
any other series of stock ranking on a parity as to dividends with the Series A
Preferred Shares, all dividends authorized and declared upon the Series A
Preferred Shares and any other series of stock ranking on a parity as to
dividends with the Series A Preferred Shares shall be authorized and declared
proportionately so that the amount of dividends authorized and declared per
Series A Preferred Share and such other series of stock shall in all cases bear
to each other the same ratio that full dividends, for the then-current dividend
period, per Series A Preferred Share (which shall not include any accumulation
in respect of unpaid dividends for prior dividend periods) and full dividends,
including required or permitted accumulations, if any, on such other series of
stock bear to each other.
 
    For a discussion of the tax treatment of distributions to stockholders, see
"United States Federal Income Tax Considerations--Taxation of United States
Stockholders" and "--Taxation of Foreign Stockholders," and for a discussion of
certain potential regulatory limitations on the Company's ability to pay
dividends, see "Risk Factors--Dividend and Other Regulatory Restrictions on
Operations of the Company."
 
AUTOMATIC EXCHANGE
 
    Each Series A Preferred Share will be exchanged automatically for one newly
issued Bank Preferred Share (i) immediately prior to such time, if any, at which
the Bank fails to declare and pay or set aside for payment when due any dividend
on any issue of its cumulative First Preferred Shares or the Bank fails to pay
or set aside for payment when due any declared dividend on any of its
non-cumulative First Preferred Shares, (ii) in the event that the Bank has a
Tier 1 risk-based capital ratio of less than 4.0% or a total risk-based capital
ratio of less than 8.0%, (iii) in the event that the Superintendent takes
control of the Bank pursuant to the Bank Act or proceedings are commenced for
the winding-up of the Bank pursuant to the Winding-up and Restructuring Act
(Canada), or (iv) in the event that the Superintendent, by order, directs the
Bank to act pursuant to subsection 485(3) of the Bank Act and the Bank elects to
cause the exchange. Upon an Exchange Event, each holder of the Series A
Preferred Shares shall be unconditionally obligated to surrender to the Bank the
certificates representing each Series A Preferred Share held by such holder,
 
                                       60
<PAGE>
and the Bank shall be unconditionally obligated to issue to such holder in
exchange for each such Series A Preferred Share a certificate representing one
Bank Preferred Share. Any Series A Preferred Shares purchased or redeemed by the
Company prior to the Time of Exchange (as defined below) shall be deemed not to
be outstanding and shall not be subject to the Automatic Exchange.
 
    The Automatic Exchange shall occur as of 8:00 a.m. Eastern Time on the date
for such exchange set forth in the requirements of the Superintendent or, if
such date is not set forth in such requirements as of 8:00 a.m. on the earliest
possible date such exchange could occur consistent with such requirements (the
"Time of Exchange"), as evidenced by the issuance by the Bank of a press release
prior to such time. As of the Time of Exchange, all of the Series A Preferred
Shares will be deemed cancelled without any further action by the Company, all
rights of the holders of the Series A Preferred Shares as stockholders of the
Company will cease, and such persons shall thereupon and thereafter be deemed to
be and shall be for all purposes holders of Bank Preferred Shares. The Company
will mail notice of the occurrence of an Exchange Event to each holder of the
Series A Preferred Shares within 30 days of such event, and the Bank will
deliver to each such holder certificates for the Bank Preferred Shares upon
surrender of such holder's certificates for the Series A Preferred Shares. The
Charter provides that, immediately after the delivery of such notice, the
existence of the Company shall terminate and the Company will be liquidated and
its affairs wound up in accordance with the procedures of the MGCL relating to
forfeiture of the charter of a corporation and expiration of corporate
existence. Until such replacement stock certificates are delivered (or in the
event such replacement certificates are not delivered), certificates previously
representing the Series A Preferred Shares shall be deemed for all purposes to
represent the Bank Preferred Shares. All corporate action necessary for the Bank
to issue the Bank Preferred Shares has been taken by the Bank. Accordingly, once
an Exchange Event occurs, no action will be required to be taken by holders of
the Series A Preferred Shares, by the Bank or by the Company in order to effect
the Automatic Exchange as of the Time of Exchange.
 
    Holders of the Series A Preferred Shares, by purchasing such Series A
Preferred Shares, will be deemed to have agreed to be bound by the unconditional
obligation to exchange such Series A Preferred Shares for the Bank Preferred
Shares upon the occurrence of an Exchange Event. The obligation of the holders
of the Series A Preferred Shares to surrender such shares and the obligation of
the Bank to issue the Bank Preferred Shares in exchange for the Series A
Preferred Shares shall be enforceable by the Bank and such holders,
respectively, against the other.
 
    Absent the occurrence of an Exchange Event, no Bank Preferred Shares will be
issued. Upon the occurrence of an Exchange Event, the Bank Preferred Shares to
be issued as part of the Automatic Exchange would constitute a newly issued
series of First Preferred Shares of the Bank ranking senior to all shares of
common stock of the Bank then issued and outstanding and equally with all other
series of First Preferred Shares of the Bank then issued and outstanding. As of
October 31, 1997, 170,461,483 shares of common stock of the Bank were issued and
outstanding. The Bank Preferred Shares would constitute 100% of the issued and
outstanding Bank Preferred Shares. The Bank Preferred Shares would have a
liquidation preference of US$1,000 and be subject to redemption on the same
terms as the Series A Preferred Shares (except that there would be no redemption
for a Tax Event). Any accrued and unpaid dividends on the Series A Preferred
Shares as of the Time of Exchange would be accounted for as accrued and unpaid
dividends on the Bank Preferred Shares. The Bank Preferred Shares would rank
equally, in terms of dividend payments and liquidation preference, with, or
senior to, any outstanding First Preferred Shares of the Bank. The Bank
Preferred Shares would not entitle the holders to vote except in certain
circumstances. Dividends on the Bank Preferred Shares would be non-cumulative
and payable at the rate of 8.45% per annum of the liquidation preference, if,
when and as declared by the Board of Directors of the Bank. The Bank does not
intend to apply for listing of the Bank Preferred Shares on any national
securities exchange or for quotation of the Bank Preferred Shares through the
National Association of Securities Dealers Automated Quotation System. Absent
the occurrence of an Exchange Event, however, the Bank will not issue any Bank
Preferred Shares, although the Bank will be able to issue First Preferred
 
                                       61
<PAGE>
Shares in series other than that of the Bank Preferred Shares. There can be no
assurance as to the liquidity of the trading markets for the Bank Preferred
Shares, if issued, or that an active public market for the Bank Preferred Shares
would develop or be maintained.
 
    Holders of the Series A Preferred Shares cannot exchange the Series A
Preferred Shares for the Bank Preferred Shares voluntarily. In addition, absent
the occurrence of the Automatic Exchange, holders of the Series A Preferred
Shares will have no dividend, voting, liquidation preference or other rights
with respect to the Bank or any security of the Bank.
 
RANKING
 
    The Series A Preferred Shares will rank prior to the Common Stock and to all
other classes and series of equity securities of the Company now or hereafter
issued, other than the Senior Preferred Shares or any other series of equity
securities of the Company expressly designated as being on a parity with
("Parity Stock") or senior to the Series A Preferred Shares as to dividend
rights and rights upon liquidation, winding up or dissolution. The Company has
the power to create and issue additional Preferred Stock or other classes of
stock ranking on a parity with the Series A Preferred Shares, or ranking junior
to the Series A Preferred Shares, without any approval or consent of the holders
of Series A Preferred Shares. So long as any Series A Preferred Shares remain
outstanding, additional shares of Senior Stock may not be issued without the
approval of the holders of at least two-thirds of the Series A Preferred Shares.
See "--Voting Rights." So long as any Series A Preferred Shares remain
outstanding, additional shares of Parity Stock may not be issued without the
approval of a majority of the Board of Directors and a majority of the
Independent Directors. See "--Independent Director Approval."
 
VOTING RIGHTS
 
    Except as indicated below, the holders of the Series A Preferred Shares will
not be entitled to vote. In the event the holders of the Series A Preferred
Shares are entitled to vote as indicated below, each Series A Preferred Share
will be entitled to one vote on matters on which holders of the Series A
Preferred Shares are entitled to vote.
 
    If, at the time of any annual meeting of the Company's stockholders for the
election of directors, the Company has failed to pay or failed to authorize and
declare and set aside for payment a quarterly dividend on any series of
Preferred Stock of the Company, including the Series A Preferred Shares, the
number of directors then constituting the Board of Directors will be increased
by at least two (if not already increased by two due to a default in preference
dividends), and the holders of the Series A Preferred Shares and the holders of
Senior Preferred Shares, voting together with the holders of all other series of
Preferred Stock as a single class, will be entitled to elect such two additional
directors to serve on the Board of Directors at each such annual meeting. Each
director elected by the holders of shares of the Preferred Stock shall continue
to serve as a director until the later of (i) the full term for which he or she
shall have been elected or (ii) the payment of one quarterly dividend on the
Preferred Stock, including the Series A Preferred Shares. Any such director may
be removed by, and shall not be removed except by, the vote of the holders of
record of the outstanding the Series A Preferred Shares and Parity Stock
entitled to vote, voting together as a single class with the holders of all
other series of Preferred Stock entitled to vote on the matter, at a meeting of
the Company's stockholders, or of the holders of the Series A Preferred Shares
and Parity Stock so entitled to vote thereon, called for that purpose. As long
as dividends on the Series A Preferred Shares shall not have been paid for the
preceding quarterly dividend period, (i) any vacancy in the office of any such
director may be filled (except as provided in the following clause (ii)) by a
person designated in an instrument in writing signed by any such remaining
director and filed with the Company, and (ii) in the case of the removal of any
such director, the vacancy may be filled by the vote of the holders of the
outstanding Series A Preferred Shares and Parity Stock entitled to vote, voting
together
 
                                       62
<PAGE>
as a single class with the holders of all other series of Preferred Stock
entitled to vote on the matter, at the same meeting at which such removal shall
be voted.
 
    The affirmative vote or consent of the holders of at least two-thirds of the
outstanding shares of each series of Preferred Stock, including the Series A
Preferred Shares, will be required (a) to create any class or series of stock
(other than the Senior Preferred Stock) which shall, as to dividends or
distribution of assets, rank prior to or on a parity with any outstanding series
of Preferred Stock other than a series which shall not have any right to object
to such creation or (b) to alter or change the provisions of the Charter
(including the terms of the Series A Preferred Shares) so as to adversely affect
the voting powers, preferences or special rights of the holders of a series of
Preferred Stock to any material extent; provided that if such amendment shall
not adversely affect all series of Preferred Stock, such amendment need only be
approved by at least two-thirds of the holders of shares of all series of
Preferred Stock adversely affected thereby.
 
REDEMPTION
 
    The Series A Preferred Shares are not redeemable prior to September 3, 2007
(except upon the occurrence of a Tax Event on or after September 3, 2002). On or
after such date, the Series A Preferred Shares may be redeemed at the option of
the Company, or its successor or any acquiring or resulting entity with respect
to the Company (including by any parent or subsidiary of the Company, any such
successor, or any such acquiring or resulting entity), as applicable, in whole
or in part, at any time or from time to time on not less than 30 nor more than
60 days' notice by mail, at the following redemption prices (expressed as a
percentage of the US$1,000 per share liquidation preference), if redeemed during
the 12-month period beginning September 3 of the years indicated below, plus the
quarterly accrued and unpaid dividend to the date of redemption, if any,
thereon:

</TABLE>
 
and thereafter at a redemption price of US$1,000 per share, plus the quarterly
accrued and unpaid dividend to the date of redemption, if any, thereon.
 
    In the event that fewer than all the outstanding Series A Preferred Shares
are to be redeemed, the number of Series A Preferred Shares to be redeemed shall
be determined by the Board of Directors, and the shares to be redeemed shall be
determined by lot or proportionately as may be determined by the Board of
Directors or by any other method as may be determined by the Board of Directors
in its sole discretion to be equitable, provided that such method satisfies any
applicable requirements of any securities exchange on which the Series A
Preferred Shares are then listed.
 
    Any such redemption must comply with applicable capital distribution
regulations of the Superintendent, which may prohibit a redemption and will
require the Superintendent's prior written approval. Unless full dividends on
the Series A Preferred Shares have been, or contemporaneously are, authorized,
 
                                       63
<PAGE>
declared and paid or authorized and declared and a sum sufficient for the
payment thereof set apart for payment for the then-current dividend period, no
Series A Preferred Shares shall be redeemed unless all outstanding Series A
Preferred Shares are redeemed and the Company shall not purchase or otherwise
acquire any Series A Preferred Shares; provided, however, that the Company may
purchase or acquire Series A Preferred Shares pursuant to a purchase or exchange
offer made on the same terms to holders of all outstanding Series A Preferred
Shares.
 
    Furthermore, the Company may, at its option, on or after September 3, 2002
and prior to September 3, 2007, redeem the Series A Preferred Shares, in whole
but not in part, at any time upon a Tax Event, at a redemption price per share
equal to the sum of (i) the quarterly accrued and unpaid dividend to the date of
redemption plus (ii) the Make-Whole Amount (as defined herein).
 
    "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue (as defined herein), assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price (as defined herein) for such prepayment
date plus 0.50%.
 
    "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the
Make-Whole Term that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of corporate
debt securities of comparable maturity to the Make-Whole Term.
 
    "Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release published by the Federal Reserve Bank of New York and
designated "Composite 3:30 p.m. Quotation for U.S. Government Securities" (or
any successor release) or (ii) if such release is not published or does not
contain such prices on such business day, (a) the average of the Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest such Reference Treasury Dealer Quotations, or (b) if the Company
obtains fewer than three such Reference Treasury Dealer Quotations, the average
of all such Quotations.
 
    "Make-Whole Amount" means, with respect to a Series A Preferred Share, the
greater of (i) 100% of the Maturity Amount of such Series A Preferred Share and
(ii) the sum of the present values of the remaining scheduled payments of
dividends on such Series A Preferred Share to September 3, 2007, plus the
present value of the Maturity Amount at September 3, 2007, discounted to the
date fixed for redemption of such Series A Preferred Share (the "redemption
date") on a quarterly basis (assuming a 360-day year consisting of 30-day
months), computed using a discount rate equal to the Adjusted Treasury Rate.
 
    "Make-Whole Term" means the period from the redemption date to September 3,
2007.
 
    "Maturity Amount" means the liquidation preference of the Series A Preferred
Shares.
 
    "Quotation Agent" means the Reference Treasury Dealer (as defined herein)
appointed by the Company.
 
    "Reference Treasury Dealer" means (i) Merrill Lynch Government Securities,
Inc. and their respective successors; provided, however, that if the foregoing
shall cease to be a primary U.S. Government securities dealer in New York City
(a "Primary Treasury Dealer"), the Company shall substitute therefor another
Primary Treasury Dealer and (ii) any other Primary Treasury Dealer selected by
the Company.
 
                                       64
<PAGE>
    "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
Company, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Company by such Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third business day preceding such redemption date.
 
    "Tax Event" means the receipt by the Company of an opinion of a nationally
recognized law firm experienced in such matters to the effect that, as a result
of (i) any amendment to, clarification of or change (including any announced
prospective change) in the laws or treaties (or any regulations thereunder) of
the United States or Canada, or any political subdivision or taxing authority
thereof or therein, affecting taxation, (ii) any judicial decision, official
administrative pronouncement, published or private ruling, regulatory procedure,
notice or announcement (including any notice or announcement of intent to adopt
such procedures or regulations) ("Administrative Action") or (iii) any amendment
to, clarification of or change in the official position or the interpretation of
such Administrative Action or any interpretation or pronouncement that provides
for a position with respect to such Administrative Action that differs from the
theretofore generally accepted position, in each case, by any legislative body,
court, governmental authority or regulatory body, irrespective of the manner in
which such amendment, clarification or change is made known, which amendment,
clarification or change is effective or such pronouncement or decision is
announced on or after the date of this Prospectus, there is more than an
insubstantial risk that (a) dividends paid or to be paid by the Company with
respect to the stock of the Company are not, or will not be, fully deductible by
the Company for United States federal income tax purposes or (b) the Company is,
or will be, subject to more than a de minimis amount of other taxes, duties or
other governmental charges and shall include an assessment by the Internal
Revenue Service that (a) dividends paid or to be paid by the Company with
respect to the stock of the Company are not, or will not be, fully deductible by
the Company for United States federal income tax purposes or (b) the Company is,
or will be, subject to more than a de minimis amount of other taxes, duties or
other governmental charges.
 
RIGHTS UPON LIQUIDATION
 
    In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Company, the holders of the Series A Preferred Shares at the
time outstanding will be entitled to receive out of assets of the Company
legally available for distribution to stockholders under applicable law, before
any distribution of assets is made to holders of Common Stock or any other class
of stock ranking junior to the Series A Preferred Shares upon liquidation, and
subject to the rights of the holders of any class or series of equity securities
having preference with respect to distribution upon liquidation and the rights
of the Company's general creditors, liquidating distributions in the amount of
US$1,000 per share, plus the quarterly accrued and unpaid dividend thereon, if
any, to the date of liquidation, without interest.
 
    After payment of the full amount of the liquidation distributions to which
they are entitled, the holders of the Series A Preferred Shares will have no
right or claim to any of the remaining assets of the Company. In the event that,
upon any such voluntary or involuntary liquidation, dissolution or winding up,
the available assets of the Company are insufficient to pay the amount of the
liquidation distributions on all the outstanding Series A Preferred Shares and
the corresponding amounts payable on all shares of other classes or series of
stock of the Company ranking on a parity with the Series A Preferred Shares in
the distribution of assets upon any liquidation, dissolution or winding up of
the affairs of the Company, then the holders of the Series A Preferred Shares
and such other classes or series of stock shall share ratably in any such
distribution of assets in proportion to the full liquidation distributions to
which they would otherwise be respectively entitled.
 
    For such purposes, the consolidation or merger of the Company with or into
any other entity, or the sale, lease or conveyance of all or substantially all
of the property or business of the Company, shall not be deemed to constitute
liquidation, dissolution or winding up of the Company.
 
                                       65
<PAGE>
INDEPENDENT DIRECTOR APPROVAL
 
    The terms of the Series A Preferred Shares require that, as long as any
Series A Preferred Shares are outstanding, certain actions by the Company be
approved by a majority of the Independent Directors. Mr. Hanley and Mr. Michel
are the Independent Directors. See "Management--Independent Directors." As long
as there are only two Independent Directors, any action that requires the
approval of a majority of the Independent Directors must be approved by both
Independent Directors. In order to be considered "independent," a director must
not be a current officer or employee of the Company or a current director,
officer or employee of the Bank or any other affiliate of the Bank. In addition,
any members of the Board of Directors elected by holders of Preferred Stock,
including the Series A Preferred Shares, will be deemed to be Independent
Directors for purposes of approving actions requiring the approval of a majority
of the Independent Directors. The actions which require approval of a majority
of the Independent Directors include (i) the issuance of additional Preferred
Stock ranking on a parity with the Series A Preferred Shares, (ii) the
modification of the Company's general distribution policy or the authorization
of any distribution in respect of the Common Stock for any year if, after taking
into account any such proposed distribution, total distributions on the Series A
Preferred Shares and the Common Stock would exceed an amount equal to the sum of
105% of the Company's "REIT taxable income" (excluding capital gains) for such
year plus net capital gains of the Company for that year, (iii) the acquisition
of Mortgage Assets other than obligations which are comparable to the Initial
Mortgage Assets issued by NB Finance, Mortgage Loans, interests in Mortgage
Loans and Partnership Interests, (iv) the redemption of any shares of Common
Stock, (v) the renewal, termination or modification of the Advisory Agreement or
the Servicing Agreement or the subcontracting of any duties thereunder to third
parties unaffiliated with the Bank, and (vi) the determination to revoke the
Company's REIT status. The Charter requires that, in determining whether any
proposed action requiring their approval is in the best interests of the
Company, the Independent Directors will consider the interests of holders of
both the Common Stock and the Preferred Stock, including, without limitation,
holders of the Series A Preferred Shares.

                          DESCRIPTION OF CAPITAL STOCK
 
    The following summaries of the material terms of the stock of the Company
and NB Finance do not purport to be complete and are qualified in their entirety
by reference to (i) Maryland law and to the Charter and Bylaws of the Company
and (ii) Bermuda law and to the Memorandum of Association ("Memorandum") and
Bye-laws of NB Finance, copies of which are available upon request to the
Company and NB Finance, respectively.
 
THE COMPANY COMMON STOCK
 
    GENERAL.  The Company is authorized by the Charter to issue up to 1,000
shares of Common Stock. The Company has outstanding 100 shares of Common Stock,
all of which are held by the Bank. In addition, the Bank currently intends that,
so long as any Series A Preferred Shares are outstanding, it will maintain
direct or indirect ownership of all of the outstanding shares of the Common
Stock.
 
    DIVIDENDS.  Holders of the Common Stock are entitled to receive dividends
if, when, and as authorized and declared by the Board of Directors out of assets
legally available therefor, provided that, if the Company fails to authorize,
declare and pay full dividends on the Series A Preferred Shares or the Senior
Preferred Shares in any dividend period, the Company may not make any dividend
payments with respect to the Common Stock until such time as dividends on all
outstanding Senior Preferred Shares and Series A Preferred Shares have been (i)
authorized, declared and paid for three consecutive dividend periods or (ii)
authorized, declared and a sum sufficient for the payment thereof set apart for
payment for the fourth consecutive dividend period.
 
    VOTING RIGHTS.  Subject to the rights, if any, of the holders of any class
or series of Preferred Stock, including Senior Preferred Stock and Series A
Preferred Shares, all voting rights are vested in the Common Stock. The holders
of the Common Stock are entitled to one vote per share. All of the issued and
outstanding shares of the Common Stock are currently held by the Bank.
 
    As the holder of all of the outstanding shares of the Common Stock, the Bank
will be able, subject to the terms of the Series A Preferred Shares and of any
other class or series of stock subsequently issued by the Company, to elect and
remove directors, amend the Charter and approve other actions requiring
stockholder approval under the MGCL or otherwise.
 
    RIGHTS UPON LIQUIDATION.  In the event of the liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, after there have
been paid or set aside for the holders of all series of Preferred Stock the full
preferential amounts to which such holders are entitled, the holders of the
Common Stock will be entitled to share equally and ratably in any assets
remaining after the payment of all debts and liabilities.
 
THE COMPANY PREFERRED STOCK
 
    GENERAL.  The Company is authorized by the Charter to issue up to 10,000,000
shares of Preferred Stock. Currently, 300,000 Series A Preferred Shares are
issued and outstanding. Subject to limitations prescribed by Maryland law and
the Charter, the Board of Directors or, if then constituted, a duly authorized
committee thereof, is authorized to issue, from the authorized but unissued
shares of stock of the Company, Preferred Stock in such classes or series as the
Board of Directors may determine and to establish, from time to time, the number
of shares of Preferred Stock to be included in any such class or series and to
fix the designation and any preferences, conversion or other rights, voting
powers, restrictions, limitations as to dividends or other distributions,
qualifications and terms and conditions of redemption of the shares of any such
class or series, and such other subjects or matters as may be fixed by
resolution of the Board of Directors.
 
                                       67
<PAGE>
    Shares of Preferred Stock, upon issuance against full payment of the
purchase price therefor and in the manner authorized by the Board of Directors,
will be fully paid and nonassessable. The specific terms of a particular class
or series of Preferred Stock are described in the Charter.
 
    The terms of the Charter relating to each class or series of Preferred Stock
set forth the preferences and other terms of such class or series, including,
without limitation, the following, as applicable: (1) the designation of such
class or series; (2) the number of shares of such class or series offered and
the liquidation preference per share of such class or series; (3) the dividend
rate(s), period(s), and/or payment date(s) or method(s) of calculation thereof
for such class or series; (4) whether dividends on such class or series of
Preferred Stock are cumulative or not and, if cumulative, the date from which
dividends on such class or series shall accumulate; (5) the provision for a
sinking fund, if any, for such class or series; (6) the terms and conditions of
redemption, if applicable, of such class or series; (7) any limitations on
direct or beneficial ownership and restrictions on transfer, in each case as may
be appropriate to preserve the status of the Company as a REIT or as otherwise
deemed appropriate by the Board of Directors; (8) the relative ranking and
preferences of such class or series as to dividend rights and rights upon
liquidation, dissolution or winding up of the affairs of the Company; (9) any
limitations on issuance of any class or series of Preferred Stock ranking senior
to or on a parity with such class or series of Preferred Stock as to dividend
rights and rights upon liquidation, dissolution or winding up of the affairs of
the Company; (10) any other specific terms, preferences, rights, limitations or
restrictions of such class or series; and (11) any voting powers of such class
or series.
 
    SENIOR PREFERRED STOCK.  The shares of the Senior Preferred Stock are
validly issued, fully paid and nonassessable and will entitle the holders
thereof to cumulative, quarterly dividends. The shares of the Senior Preferred
Stock are redeemable, at any time in whole, but not in part, at the option of
the Company at a price equal to the liquidation preference thereof plus accrued
and unpaid dividends thereon through the redemption date. On the December 30th
following each ten year anniversary of the issuance of the Senior Preferred
Stock, each holder of Senior Preferred Stock may require the Company to purchase
such holder's Senior Preferred Stock at the liquidation preference thereof plus
accrued and unpaid dividends thereon through the date of redemption. The Senior
Preferred Stock ranks senior to the Common Stock and the Series A Preferred
Shares as to dividend rights and rights upon liquidation, winding up or
dissolution. Except as provided below, holders of the Senior Preferred Stock
have no voting rights. If at any time the Company shall have failed to pay all
accrued and unpaid dividends on the Senior Preferred Stock when due, the Company
may not pay dividends on, or make certain other payments with respect to, the
Series A Preferred Shares or the Common Stock or any other series of stock
ranking junior to the Senior Preferred Stock. If, at the time of any annual
meeting of the Company's stockholders for the election of directors, the Company
has failed to pay or failed to authorize and declare and set aside for payment a
quarterly dividend on any series of Preferred Stock, including the Senior
Preferred Shares, the number of directors then constituting the Board of
Directors will be increased by at least two (if not already increased by two due
to a default in preference dividends), and the holders of the Senior Preferred
Shares, voting together with the holders of all other series of Preferred Stock
as a single class, will be entitled to elect such two additional directors to
serve on the Board of Directors at each such annual meeting.
 
POWER TO ISSUE ADDITIONAL SHARES OF COMMON STOCK AND PREFERRED STOCK
 
    The Company believes that the power of the Board of Directors to issue
additional authorized but unissued shares of Common Stock or Preferred Stock and
to classify or reclassify unissued shares of Common Stock or Preferred Stock and
thereafter to cause the Company to use such classified or reclassified shares of
stock will provide the Company with increased flexibility in structuring
possible future financings and acquisitions and in meeting other needs which
might arise. Except as set forth under "Description of New Preferred
Shares--Voting Rights," the additional shares of stock will be available for
issuance without further action by the Company's stockholders, unless such
action is required by applicable law or the rules of any stock exchange or
automated quotation system on which the Company's securities may be listed or
traded.
 
                                       68
<PAGE>
RESTRICTIONS ON OWNERSHIP AND TRANSFER
 
    The Charter contains certain restrictions on the number of shares of
Preferred Stock that individual stockholders may directly or beneficially own.
These restrictions also apply to investors owning Series A Preferred Shares
through Depositary Shares. For the Company to qualify, and to continue to
qualify, as a REIT under the Code, no more than 50% of the value of its
outstanding shares of capital stock may be owned, directly or indirectly, by
five or fewer individuals (defined by the Code to include certain entities)
during the last half of a taxable year (other than the first year) or during a
proportionate part of a shorter taxable year (the "Five or Fewer Test"). The
Five or Fewer Test is applied using certain consecutive ownership rules. The
stock of the Company must also be beneficially owned by 100 or more persons
during at least 335 days of a taxable year (other than the first year) or during
a proportionate part of a shorter taxable year (the "One Hundred Persons Test").
Absent the restrictions on the number of shares of Preferred Stock that
individual stockholders may acquire and own (directly or indirectly), there
would be a possibility that the Company might fail the Five or Fewer Test. The
Company issued the Senior Preferred Stock in order to ensure continued
compliance with the One Hundred Persons Test without constant monitoring. The
provisions of the Senior Preferred Stock include a restriction that if any
transfer of shares of such stock would cause the shares of such series to be
owned by fewer than 100 persons, such transfer shall be null and void and the
intended transferee will acquire no rights to the stock.
 
    Subject to certain exceptions specified in the Charter, no natural person or
entity which is considered to be an individual under Section 542(a)(2) of the
Code is permitted to own (including shares deemed to be owned by virtue of the
relevant attribution provisions of the Code), more than 5% (the "Ownership
Limit") of any issued and outstanding class or series of Preferred Stock,
including shares owned through Depositary Shares. The Board of Directors may
(but in no event will be required to), upon receipt of a ruling from the IRS or
an opinion of counsel satisfactory to it, raise or waive the Ownership Limit
with respect to a holder if such holder's ownership will not then or in the
future jeopardize the Company's status as a REIT.
 
    The Charter provides that shares of any class or series of Preferred Stock
owned, or deemed to be owned, by, or transferred to, a stockholder in violation
of the Ownership Limit, or which would otherwise cause the Company to fail to
qualify as a REIT (the "Excess Shares"), will automatically be transferred, by
operation of law, to a trustee in trust for the exclusive benefit of a charity
to be named by the Company as of the day prior to the day the prohibited
transfer took place. Any distributions paid with respect to such Excess Shares
prior to the discovery of the prohibited transfer or ownership are to be repaid
by the original transferee to the Company and by the Company to the trustee;
subject to applicable law, any vote of the Excess Shares while the Excess Shares
were held by the original transferee prior to the Company's discovery of the
prohibited transfer shall be void and the original transferee shall be deemed to
have given its proxy to the trustee. In liquidation, the original transferee's
ratable share of the Company's assets would be limited to the price paid by the
original transferee for the Excess Shares or, if no value was given, the price
per share equal to the closing market price on the date of the purported
transfer. The trustee of the trust shall promptly sell the Excess Shares to any
person whose ownership thereof is not prohibited, whereupon the interest of the
trust shall terminate. Proceeds of such sale shall be paid to the original
transferee up to its purchase price (or, if the original transferee did not
purchase the shares, the value on the date of the purported transfer) and any
remaining proceeds shall be paid to the beneficiary of the trust.
 
    The constructive ownership rules of the Code are complex and may cause
Preferred Stock owned, directly or indirectly, by a group of related individuals
and/or entities to be deemed to be constructively owned by a particular
individual or entity. As a result, the acquisition or ownership of less than 5%
of a class or series of issued and outstanding Preferred Stock (or the
acquisition or ownership of an interest in an entity that owns shares of such
series of Preferred Stock) by an individual or entity could cause that
individual or entity (or another individual or entity) to own constructively in
excess of 5% of such class or series of Preferred Stock, and thus subject such
stock to the applicable Ownership Limit. Direct or
 
                                       69
<PAGE>
constructive ownership in excess of the Ownership Limit would cause ownership of
the shares in excess of the limit to be transferred to the trustee.
 
    The Ownership Limit will not be automatically removed even if the REIT
Provisions (as defined herein) are changed so as to eliminate any ownership
concentration limitation or if the ownership concentration limitation is
increased. The foregoing restrictions on transferability and ownership will not
apply, however, if the Board of Directors determines that it is no longer in the
best interests of the Company to attempt to qualify, or to continue to qualify,
as a REIT.
 
    The Charter requires that any person who beneficially owns 0.5% (or such
lower percentage as may be required by the Code or the Treasury Regulations) of
the outstanding shares of any class or series of Preferred Stock, including
shares owned through Depositary Shares, must provide certain information to the
Company within 30 days of June 30 and December 31 of each year. In addition,
each such stockholder shall upon demand be required to disclose to the Company
in writing such information as the Company may request in order to determine the
effect, if any, of such stockholder's actual and constructive ownership on the
Company's status as a REIT and to ensure compliance with the Ownership Limit.
 
SUPERMAJORITY DIRECTOR APPROVAL
 
    The Charter requires approval by two-thirds of the Board of Directors in
order for the Company to file a voluntary petition of bankruptcy.
 
BUSINESS COMBINATIONS
 
    Under MGCL, certain "business combinations" (including a merger,
consolidation, share exchange, or, in certain circumstances, an asset transfer
or issuance or reclassification of equity securities) between a Maryland
corporation and any person who beneficially owns, directly or indirectly, 10% or
more of the voting power of the corporation's shares or an affiliate of the
corporation who, at any time within the two-year period prior to the date in
question, was the beneficial owner of 10% or more of the voting power of the
then outstanding voting stock of the corporation (an "Interested Stockholder")
or an affiliate of such an Interested Stockholder are prohibited for five years
after the most recent date on which the Interested Stockholder becomes an
Interested Stockholder. Thereafter, any such business combination must be (i)
approved by the board of directors of such corporation and (ii) approved by the
affirmative vote of at least (a) 80% of the votes entitled to be cast by holders
of outstanding voting shares of the corporation and (b) two-thirds of the votes
entitled to be cast by holders of voting shares other than voting shares held by
the Interested Stockholder with whom (or with whose affiliate) the business
combination is to be effected, unless, among other conditions, the corporation's
common stockholders receive a minimum price (as defined in the statute) for
their shares and the consideration is received in cash or in the same form as
previously paid by the Interested Stockholder for its shares. These provisions
of the MGCL do not apply, however, to business combinations that are approved or
exempted by the board of directors of the corporation prior to the time that the
Interested Stockholder becomes an Interested Stockholder. The Bank beneficially
owns more than 10% of the Company's voting shares and would, therefore, together
with its affiliates, be subject to the business combination provision of the
MGCL. However, pursuant to the statute, the Company has exempted any business
combinations involving the Bank and any present or future affiliate thereof and,
consequently, the five-year prohibition and the super-majority vote requirements
will not apply to business combinations between any of them and the Company. As
a result, the Bank and any present or future affiliate thereof may be able to
enter into business combinations with the Company that may not be in the best
interest of its stockholders without compliance by the Company with the
super-majority vote requirements and the other provisions of the statute.
 
CONTROL SHARE ACQUISITIONS
 
    The MGCL provides that "control shares" of a Maryland corporation acquired
in a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled
 
                                       70
<PAGE>
to be cast by stockholders, excluding shares owned by the acquiror and officers
and directors who are employees of the corporation. "Control shares" are shares
which, if aggregated with all other shares previously acquired which the person
is entitled to vote, would entitle the acquiror to vote (i) 20% or more but less
than one-third; (ii) one-third or more but less than a majority; or (iii) a
majority of the outstanding shares. Control shares do not include shares that
the acquiring person is entitled to vote on the basis of prior stockholder
approval. A "control share acquisition" means the acquisition of control shares
subject to certain exemptions.
 
    A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain conditions (including an undertaking to pay expenses),
may compel the board of directors of the corporation to call a special meeting
of stockholders to be held within 50 days of demand to consider the voting
rights of the shares. If no request for a meeting is made, the corporation may
itself present the question at any stockholders meeting.
 
    If voting rights are not approved at the meeting or if the acquiring person
does not deliver an acquiring person statement as required by the statute, then,
subject to certain conditions and limitations, the corporation may redeem any or
all of the control shares (except those for which voting rights have previously
been approved) for fair value determined, without regard to the absence of
voting rights for the control shares, as of the date of the last control share
acquisition by the acquiror or of any meeting of stockholders at which the
voting rights of such shares are considered and not approved. If voting rights
for control shares are approved at a stockholders meeting and the acquiror
becomes entitled to vote a majority of the shares entitled to vote, all other
stockholders may exercise appraisal rights. The fair value of the shares as
determined for purposes of such appraisal rights may not be less than the
highest price per share paid by the acquiror in the control share acquisition.
 
    The control share acquisition statute does not apply to shares acquired in a
merger, consolidation or share exchange if the corporation is a party to the
transaction or to acquisitions approved or excepted by the charter or bylaws of
the corporation prior to a control share acquisition.
 
    The Bylaws of the Company contain a provision exempting from the control
share statute any shares of stock owned by the Bank or any affiliate of the
Bank.
 
NB FINANCE COMMON STOCK
 
    GENERAL.  NB Finance is authorized by the Memorandum to issue up to 12,000
shares of common stock, par value US$1.00 per share. NB Finance has outstanding
12,000 shares of common stock, all of which are held by the Bank.
 
    DIVIDENDS.  Holders of common stock of NB Finance are entitled to receive
dividends if, when, and as authorized and declared by the Board of Directors of
NB Finance in proportion to the number of shares held by them.
 
    VOTING RIGHTS.  Holders of common stock of NB Finance are entitled to one
vote per share.
 
    RIGHTS UPON WINDING-UP OR DISSOLUTION.  In the event of a winding-up or
dissolution of NB Finance, whether voluntary or involuntary or for purposes of
reorganization or otherwise or upon any distribution of capital, the holders of
common stock of NB Finance are entitled to the surplus assets of NB Finance.
 
FORM, DENOMINATION, BOOK-ENTRY PROCEDURES AND TRANSFER
 
    The Series A Preferred Shares will be issued only as fully registered
securities registered in the name of Cede & Co. (as nominee for The Depositary
Trust Company ("DTC")). One or more fully registered global Series A Preferred
Share certificates representing the Series A Preferred Shares (the "Series A
Preferred Global Certificate") will be deposited with DTC for credit to an
account of a direct or indirect participant in DTC as described below.
Beneficial interests in the Series A Preferred Share Global Certificate may not
be exchanged for the Series A Preferred Shares in certificated form.
 
                                       71
<PAGE>
    The Depositary Shares may be issued as fully registered securities
registered in the name of Cede & Co. (as nominee of DTC) or in registered,
certificated (i.e., non-global) form. One or more global Depositary Share
certificates representing the Depositary Shares (the "Depositary Share Global
Certificate" and, together with the Series A Preferred Share Global Certificate,
the "Global Certificates") may be deposited with DTC for credit to an account of
a direct or indirect participant of DTC as described below. Beneficial interests
in the Series A Preferred Share Global Certificate may be exchanged through DTC
for a beneficial interest in the Depositary Share Global Certificate. Beneficial
interests in the Depositary Share Global Certificate may be exchanged for
Depositary Shares in certificated form.
 
    Except as set forth below, the Global Certificates may be transferred, in
whole and not in part, only to another nominee of DTC or to a successor of DTC
or its nominee, and such transfer shall be effective only when reflected in the
securities register maintained by or on behalf of the Company.
 
DTC PROCEDURES
 
    DTC has advised the Company that DTC is a limited-purpose trust company
created to hold securities for its participating organizations (collectively,
the "Participants") and to facilitate the clearance and settlement of
transactions in those securities between Participants through electronic
book-entry changes in accounts of its Participants. The Participants include
securities brokers and dealers (including the Initial Purchaser), banks, trust
companies, clearing corporations and certain other organizations. Access to
DTC's system is also available to other entities such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly (collectively, the "Indirect
Participants"). Persons who are not Participants may beneficially own securities
held by or on behalf of DTC only through the Participants or the Indirect
Participants. The ownership interest and transfer of ownership interest of each
actual purchaser of each security held by or on behalf of DTC are recorded on
the records of the Participants and Indirect Participants.
 
    DTC has also advised the Company that, pursuant to procedures established by
it, (i) upon deposit of the Global Certificates, DTC will credit the accounts of
Participants designated by the transfer agent or the Depositary with portions of
the liquidation preference of the Global Certificates and (ii) ownership of such
interests in the Global Certificates will be shown on, and the transfer of
ownership thereof will be effected only through, records maintained by DTC (with
respect to the Participants) or by the Participants and the Indirect
Participants (with respect to other owners of beneficial interests in the Global
Certificates).
 
    Investors in the Global Certificates may hold their interests therein
directly through DTC if they are participants in such system, or indirectly
through organizations which are participants in such system. All interests in
the Global Certificates may be subject to the procedures and requirements of
DTC. The laws of some states require that certain persons take physical delivery
in certificated form of securities that they own. Consequently, the ability to
transfer beneficial interests in the Series A Preferred Share Global
Certificates to such persons will be limited to that extent. Because DTC can act
only on behalf of Participants, which in turn act on behalf of Indirect
Participants and certain banks, the ability of a person having beneficial
interests in the Series A Preferred Share Global Certificates to pledge such
interests to persons or entities that do not participate in the DTC system, or
otherwise take actions in respect of such interests, may be affected by the lack
of a physical certificate evidencing such interests. For certain other
restrictions on the transferability of the Series A Preferred Shares, see
"Certificated New Preferred Shares."
 
    Except as described below, owners of interests in the Global Certificates
will not have Series A Preferred Shares or Depositary Shares, as the case may
be, registered in their name, will not receive physical delivery of Series A
Preferred Shares or Depositary Shares, as the case may be, in certificated form
and will not be considered the registered owners or holders thereof for any
purpose.
 
    Payments in respect of the Global Certificates registered in the name of DTC
or its nominee will be payable to DTC in its capacity as the registered holder.
The transfer agent or Depositary will treat the persons in whose names the
Series A Preferred Shares or Depositary Shares, respectively, including the
 
                                       72
<PAGE>
Global Certificates, are registered as the owners thereof for the purpose of
receiving such payments and for any and all other purposes whatsoever.
Consequently, neither the transfer agent nor the Depositary nor any agent
thereof has or will have any responsibility or liability for (i) any aspect of
DTC's records or any Participant's or Indirect Participant's records relating to
or payments made on account of beneficial ownership interests in the Global
Certificates, or for maintaining, supervising or reviewing any of DTC's records
or any Participant's or Indirect Participant's records relating to the
beneficial ownership interests in the Global Certificates or (ii) any other
matter relating to the actions and practices of DTC or any of its Participants
or Indirect Participants. DTC has advised the Company that its current practice,
upon receipt of any payment in respect of securities such as the Series A
Preferred Shares or the Depositary Shares, is to credit the accounts of the
relevant Participants with the payment on the payment date, in amounts
proportionate to their respective holdings in liquidation preference of
beneficial interests in the relevant security as shown on the records of DTC
unless DTC has reason to believe it will not receive payment on such payment
date. Payments by the Participants and the Indirect Participants to the
beneficial owners of Series A Preferred Shares or the Depositary Shares will be
governed by standing instructions and customary practices and will be the
responsibility of the Participants or the Indirect Participants and will not be
the responsibility of DTC, the transfer agent, the Depositary or the Company.
Neither the Company nor the transfer agent nor the Depositary will be liable for
any delay by DTC or any of its Participants in identifying the beneficial owners
of the Series A Preferred Shares or the Depositary Shares, as the case may be,
and the Company and the transfer agent or the Depositary may conclusively rely
on and will be protected in relying on instructions from DTC or its nominee for
all purposes.
 
    Secondary market trading activity in interests in the Global Certificates
will settle in immediately available funds, subject in all cases to the rules
and procedures of DTC and its participants. Transfers between Participants in
DTC will be effected in accordance with DTC's procedures, and will be settled in
same-day funds.
 
    DTC has advised the Company that it will take any action permitted to be
taken by a holder of Series A Preferred Shares or Depositary Shares, as the case
may be, only at the direction of one or more Participants to whose account with
DTC interests in the Global Certificates are credited and only in respect of
such portion of the liquidation preference of the Series A Preferred Shares or
the Depositary Shares as to which such Participant or Participants has or have
given such direction.
 
    The information in this section concerning DTC and its book-entry systems
has been obtained from sources that the Company believes to be reliable, but the
Company does not take responsibility for the accuracy thereof.
 
    Although DTC has agreed to the foregoing procedures to facilitate transfers
of interest in the Global Certificates among participants in DTC, they are under
no obligation to perform or to continue to perform such procedures, and such
procedures may be discontinued at any time. Neither the Company nor the transfer
agent will have any responsibility for the performance by DTC or its
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations.
 
CERTIFICATED SERIES A PREFERRED SHARES AND CERTIFICATED DEPOSITARY SHARES
 
    The Global Certificates are exchangeable for Series A Preferred Shares or
Depositary Shares, as the case may be, in registered certificated form if (i)
DTC (x) notifies the Company that it is unwilling or unable to continue as
Depositary for the Global Certificates and the Company thereupon fails to
appoint a successor Depositary within 90 days or (y) has ceased to be a clearing
agency registered under the Exchange Act or (ii) the Company in its sole
discretion elects to cause the issuance of the Series A Preferred Shares or
Depositary Shares, as the case may be, in certificated form. In all cases,
certificated Series A Preferred Shares or Depositary Shares, as the case may be,
delivered in exchange for the Global Certificates or beneficial interests
therein will be registered in the names, and issued in any approved
denominations, requested by or on behalf of DTC (in accordance with its
customary procedures). Further, the Depositary Share Global Certificate will be
exchangeable for Depositary Shares in registered certificated form at any time.

                UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
    The following summary of the material United States federal income tax
considerations with respect to the Offering is for general information only and
is not tax advice. The discussion set forth below, to the extent that it
constitutes a summary of legal matters or legal conclusions, has been reviewed
by Shearman & Sterling, and it is such firm's opinion that such discussion is
accurate in all material respects. In rendering such opinion, Shearman &
Sterling has relied on Desjardins Ducharme Stein Monast, with respect to certain
matters of Quebec law, Osler Hoskin & Harcourt, with respect to certain matters
of Ontario law, and Conyers Dill & Pearman, with respect to certain matters of
Bermuda law. The discussion below is based on the Code, existing and proposed
Treasury Regulations issued thereunder, and administrative and judicial
interpretations thereof, all as of the date hereof and all of which are subject
to change, possibly with retroactive effect. The discussion below does not
address all aspects of taxation that may be relevant in the particular
circumstances of each stockholder or to certain types of stockholders (including
insurance companies, tax-exempt entities, financial institutions or
broker-dealers persons that hold stock in the Company other than as a capital
asset, foreign corporations and persons who are not citizens or residents of the
United States, except to the extent discussed) subject to special treatment
under the United States federal income tax laws.
 
   
    THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH BELOW IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION. HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH
RESPECT TO THE SPECIFIC TAX CONSEQUENCES TO THEM, INCLUDING THE TAX CONSEQUENCES
UNDER STATE, LOCAL, FOREIGN AND OTHER NON-FEDERAL TAX LAWS AND THE POSSIBLE
EFFECTS OF CHANGES IN FEDERAL AND NON-FEDERAL TAX LAWS.
    
 
QUALIFICATION OF THE COMPANY AS A REIT
 
    GENERAL.
 
    The Company will elect to be taxable as a REIT under Sections 856 through
860 of the Code and the applicable Treasury Regulations (the "REIT Requirements"
or the "REIT Provisions"), commencing with its taxable year ended December 31,
1997. The Company believes that, commencing with its taxable year ended December
31, 1997, it will be owned and organized and will operate in such a manner as to
qualify for taxation as a REIT. While the Company intends to continue to operate
in such a manner, no assurance can be given that it will operate in a manner so
as to qualify or remain qualified as a REIT.
 
    The REIT Requirements are technical and complex. The following discussion
sets forth only the material aspects of those requirements. This summary is
qualified in its entirety by the applicable Code provisions, rules and
regulations promulgated thereunder, and administrative and judicial
interpretations thereof.
 
   
    In the opinion of Shearman & Sterling, commencing with the Company's taxable
year ended December 31, 1997, the Company will be organized in conformity with
the requirements for qualification as a REIT, and its proposed method of
operation will enable it to meet the requirements for qualification and taxation
as a REIT under the Code. However, no transaction closely comparable to that
contemplated herein has been the subject of any administrative pronouncement or
judicial decision and this opinion is based on certain factual assumptions
relating to the organization and operation of the Company and is conditioned
upon certain representations made by the Company as to factual matters, such as
the organization and expected manner of operation of the Company. In addition,
this opinion is based upon the factual representations of the Company concerning
its business and Mortgage Assets set forth in this Prospectus and certain legal
opinions provided by Canadian and Bermudian counsel to the Bank. Such
qualification and taxation as a REIT, moreover, depends upon the Company's
ability to satisfy, through actual annual operating results, the distribution
levels, the diversity of stock ownership and the REIT
    
 
                                       74
<PAGE>
Requirements discussed below, the satisfaction of which will not be reviewed by
Shearman & Sterling on a continuing basis. No assurance can be given that the
actual results of the Company's operation for any one taxable year will satisfy
such requirements. See "Tax Risks--Adverse Consequences of Failure to Qualify as
a REIT."
 
   
    There can be no assurance that the Company will continue to qualify as a
REIT in any particular taxable year, given the highly complex nature of the
rules governing REITs, the ongoing importance of factual determinations, and the
possibility of future changes in the circumstances of the Company. If the
Company were not to qualify as a REIT in any particular year, it would be
subject to United States federal income tax as a regular, domestic corporation
and its stockholders (including holders of Depositary Shares) would be subject
to tax in the same manner as stockholders of such a corporation. In this event,
the Company would likely be subject to a substantial United States federal
income tax liability in respect of each taxable year that it fails to qualify as
a REIT and the income available for distribution to the holders of the Series A
Preferred Shares and, accordingly, the Depositary Shares could be significantly
reduced or eliminated.
    
 
    The following is a brief summary of certain of the technical requirements
that the Company must meet on an ongoing basis in order to qualify, and remain
qualified, as a REIT under the Code:
 
    STOCK OWNERSHIP TESTS.
 
   
    The capital stock of the Company must be held by at least 100 persons during
approximately 90% or more of the taxable year and, at all times during the last
half of the taxable year, no more than 50% of the value of such capital stock
may be owned, directly or indirectly, by five or fewer individuals. Under the
Code, certain tax-exempt entities, such as private foundations and certain
unemployment compensation trusts, are treated as individuals for purposes of the
latter test. These stock ownership requirements must be satisfied in the
Company's second taxable year and in each subsequent taxable year. The Charter
provides restrictions regarding the transfer of the Company's shares in order to
aid in meeting the stock ownership requirements. See "Description of Capital
Stock Restrictions on Ownership and Transfer." The Company has also issued
shares of Senior Preferred Stock to ensure compliance with the 100 person
ownership requirement for REIT status without constant monitoring. For the
foregoing purposes, the holders of Depositary Shares and not the Depositary are
considered holders of the Series A Preferred Shares.
    
 
    ASSET TESTS.
 
    The Company must generally meet the following asset tests (the "REIT Asset
Tests") at the close of each quarter of each taxable year:
 
        (a) at least 75% of the value of the Company's total assets must consist
    of Qualified REIT Real Estate Assets, Government securities, cash, and cash
    items (the "75% Asset Test"); and
 
        (b) not more than 25% of the Company's total assets may consist of
    securities other than those taken into account for purposes of the 75% Asset
    Test and, of those securities, (i) the value of the securities of any one
    issuer (other than another REIT) may not exceed 5% of the value of the
    Company's total assets, and (ii) the Company may not own more than 10% of
    the outstanding voting securities of any such issuer.
 
   
    The Company believes that the Initial Mortgage Assets issued by NB Finance
constitute Qualified REIT Real Estate Assets. In addition, the Company does not
expect that the value of any security (other than a Qualified REIT Real Estate
Asset) of any one entity would ever exceed 5% of the Company's total assets, and
the Company does not expect to own more than 10% of any one issuer's voting
securities.
    
 
                                       75
<PAGE>
    GROSS INCOME TESTS.
 
   
    The Company must generally meet the following gross income tests (the "REIT
Gross Income Tests") for each taxable year:
    
 
        (a) at least 75% of the Company's gross income must be derived from
    certain specified sources including interest on obligations secured by
    mortgages on real property, gain from the disposition of Qualified REIT Real
    Estate Assets or "qualified temporary investment income" (i.e., income
    derived from "new capital" within one year of the receipt of such capital)
    (the "75% Gross Income Test"); and
 
        (b) at least 95% of the Company's gross income must consist of income
    qualifying for the 75% Gross Income Test, dividends, interest, and gains
    from the sale of stock or other securities (including certain interest rate
    swap and cap agreements entered into to hedge variable rate debt incurred to
    acquire Qualified REIT Real Estate Assets) not held for sale in the ordinary
    course of business (the "95% Gross Income Test").
 
    The Company intends to maintain its REIT status by carefully monitoring its
income, including income from sales of Mortgage Assets, to comply with the REIT
Gross Income Tests. Under certain circumstances, such as an unanticipated
decrease in the qualifying income of the Company, which may result in the
Company's non-qualifying income exceeding 5% of its gross income, the Company
may be unable to comply with certain of the REIT Gross Income Tests. See
"Taxation of the Company" for a discussion of the tax consequences of a failure
to comply with the REIT Gross Income Tests.
 
    DISTRIBUTION REQUIREMENT.
 
   
    The Company must generally distribute dividends (other than capital gain
dividends) to its stockholders in an amount at least equal to (A) the sum of (i)
95% of the Company's REIT taxable income (which is defined generally as the
taxable income of the Company computed without regard to the dividends paid
deduction and the Company's net capital gain) plus (ii) 95% of the Company's net
income (after tax), if any, from foreclosure property, minus (B) the sum of
certain items of noncash income. Such distributions must be paid in the taxable
year to which they relate or in the following taxable year if declared before
the Company timely files its tax return for such year and if paid on or before
the first regular dividend payment after such declaration.
    
 
    The Company intends to monitor on an ongoing basis its compliance with the
REIT requirements described above. In order to maintain its REIT status, the
Company will be required to limit the types of assets that it might otherwise
acquire, or hold certain assets at times when it might otherwise have determined
that the sale or other disposition of such assets would be desirable.
 
    TAXATION OF THE COMPANY.
 
    In any year in which the Company qualifies as a REIT, the Company will
generally not be subject to United States federal income tax on that portion of
its REIT taxable income or capital gain which is distributed to its
stockholders. The Company will, however, be subject to United States federal
income tax at normal corporate income tax rates upon any undistributed REIT
taxable income or capital gain.
 
    Notwithstanding its qualification as a REIT, the Company may be subject to
tax in certain circumstances. If the Company fails to satisfy either the 75%
Gross Income Test or the 95% Gross Income Test, but nonetheless maintains its
qualification as a REIT because certain other requirements are met, it will
generally be subject to a 100% tax on the greater of the amount by which the
Company fails either the 75% Gross Income Test or the 95% Gross Income Test
(multiplied by a fraction intended to reflect the Company's profitability). The
Company will also be subject to a tax of 100% on net income derived from any
"prohibited transaction" and, if the Company has (i) net income from the sale or
other disposition of "foreclosure property" which is held primarily for sale to
customers in the ordinary course of business or (ii) other non-qualifying net
income from foreclosure property, it will be subject to United States federal
 
                                       76
<PAGE>
income tax on such income at the highest corporate income tax rate. In addition,
if the Company fails to distribute during each calendar year at least the sum of
(i) 85% of its REIT ordinary income for such year, (ii) 95% of its REIT capital
gain net income for such year, and (iii) any undistributed taxable income from
prior periods, the Company would be subject to a 4% United States federal excise
tax on the excess of such required distribution over the amounts actually
distributed during the year. The Company may also be subject to the corporate
alternative minimum tax, as well as other taxes in certain situations not
presently contemplated.
 
    If the Company fails to qualify as a REIT in any taxable year and certain
relieving provisions of the Code do not apply, the Company would be subject to
United States federal income tax (including any applicable alternative minimum
tax) in the same manner as a regular, domestic corporation. Distributions to
stockholders in any year in which the Company fails to qualify as a REIT would
not be deductible by the Company and would generally not be required to be made
under the Code. Further, unless entitled to relief under certain provisions of
the Code, the Company would be disqualified from reelecting REIT status for the
four taxable years following the year during which it became disqualified.
 
TAX TREATMENT OF AUTOMATIC EXCHANGE
 
   
    Upon the occurrence of an Exchange Event, the outstanding Series A Preferred
Shares will be automatically exchanged on a one-for-one basis for the Bank
Preferred Shares. Immediately upon the occurrence of an Exchange Event, each
Depositary Share will represent a one-fortieth interest in a Bank Preferred
Share and will no longer represent a fractional interest in a Series A Preferred
Share. See "Description of Series A Preferred Shares--Automatic Exchange" and
"Description of Depositary Shares--Automatic Exchange." The Automatic Exchange
will be a taxable exchange with respect to which each holder of the Series A
Preferred Shares or the Depositary Shares will recognize a gain or loss, as the
case may be, measured by, in the case of Series A Preferred Shares, the
difference between the adjusted basis of such holder in its Series A Preferred
Shares and the fair market value of the Bank Preferred Shares received by such
holder in the Automatic Exchange and, in the case of the Depositary Shares, the
difference between the adjusted basis of such holder in the Depositary Shares
and the fair market value of the Bank Preferred Shares represented by the
Depositary Shares at the time of the Automatic Exchange. Assuming that such
holder's Series A Preferred Shares or Depositary Shares, as the case may be,
were held as capital assets prior to the Automatic Exchange, any such gain or
loss will be capital gain or loss. The basis of a holder in the Bank Preferred
Shares received in the Automatic Exchange or in the Depositary Shares
immediately after the Automatic Exchange will be the fair market value of the
Bank Preferred Shares at the time of the Automatic Exchange or the fair market
value of the Bank Preferred Shares represented by the Depositary Shares at the
time of the Automatic Exchange, respectively.
    
 
TAXATION OF SERIES A PREFERRED SHARES AND DEPOSITARY SHARES
 
   
    Distributions (including constructive distributions) on the Series A
Preferred Shares and, accordingly, the Depositary Shares made to holders other
than tax-exempt entities, will generally be subject to United States federal
income tax as ordinary income to the extent of the Company's current and
accumulated earnings and profits as determined for United States federal income
tax purposes. If the amount distributed in respect of the Series A Preferred
Shares and, accordingly, the Depositary Shares to a holder thereof exceeds the
holder's allocable share of such earnings and profits, the excess will be
treated first as a nontaxable return of capital to the extent of such holder's
adjusted basis in the Series A Preferred Shares or the Depositary Shares, as the
case may be, and, thereafter, as a gain from the sale or exchange of a capital
asset.
    
 
    Distributions designated by the Company as capital gain dividends will
generally be subject to tax as long-term capital gain to the extent that the
distribution does not exceed the Company's actual net capital gain for the
taxable year (although corporations may be required to treat up to 20% of
certain capital gain dividends as ordinary income). Distributions by the
Company, whether characterized as ordinary income
 
                                       77
<PAGE>
   
or as capital gain, are not eligible for the corporate dividends received
deduction. In the event that the Company realizes a loss for a taxable year,
holders of the Series A Preferred Shares or the Depositary Shares will not be
permitted to deduct any share of that loss. Future Treasury Regulations may
require that holders of the Series A Preferred Shares or the Depositary Shares
take into account, for purposes of computing their individual alternative
minimum tax liability, certain tax preference items of the Company.
    
 
   
    Dividends declared during the last quarter of a calendar year and actually
paid during January of the following year will generally be treated as having
been received by the holders of the Series A Preferred Shares and, accordingly,
the Depositary Shares on December 31 of the year in which the dividends were
declared and not on the date actually received. In addition, the Company may
elect to treat certain other dividends distributed after the close of a taxable
year as having been paid during such taxable year, but holders of the Series A
Preferred Shares and, accordingly, the Depositary Shares will be treated as
having received such dividends in the taxable year in which the distribution is
made.
    
 
   
    Upon a sale or other disposition of the Series A Preferred Shares or the
Depositary Shares a holder of the Series A Preferred Shares or the Depositary
Shares, as the case may be, will generally recognize a capital gain or loss in
an amount equal to the difference between the amount realized and such holder's
adjusted basis in such stock, which gain or loss will be long term if the stock
has been held for more than the applicable holding period. Any loss on the sale
or exchange of the Series A Preferred Shares or the Depositary Shares held by
the holder thereof for six months or less will generally be treated as a
long-term capital loss to the extent of any long-term capital gain dividends
received by such holder.
    
 
   
    In any year in which the Company does not qualify as a REIT, distributions
made to its stockholders would be taxable in the same manner discussed above,
except that (i) no distributions could be designated as capital gain dividends,
(ii) distributions would be eligible for the corporate dividends received
deduction, (iii) the excess inclusion income rules would not apply, and (iv)
stockholders would not receive any share of the Company's tax preference items.
In such event, however, the Company would likely be subject to a substantial
United States federal income tax liability, and the amount of income available
for distribution to its stockholders (including holders of the Series A
Preferred Shares and, accordingly, the Depositary Shares) would be significantly
reduced or eliminated.
    
 
   
    The Company is required under Treasury Regulations to demand annual written
statements from the record holders of designated percentages of its stock
(including the Depositary Shares) disclosing the actual and constructive
ownership of such stock and to maintain permanent records showing the
information it has received as to the actual and constructive ownership of such
stock and a list of those persons failing or refusing to comply with such
demand.
    
 
TAXATION OF TAX-EXEMPT ENTITIES
 
   
    Subject to the discussion below regarding a "pension-held REIT," a
tax-exempt holder of the Series A Preferred Shares or the Depositary Shares will
generally not be subject to tax on distributions from the Company or gain
realized on the sale of the Series A Preferred Shares or the Depositary Shares,
as the case may be, provided that such holder has not incurred indebtedness to
purchase or hold its Series A Preferred Shares or Depositary Shares, that such
shares are not otherwise used in an unrelated trade or business of such holder,
and that the Company, consistent with its present intent, does not hold a
residual interest in a REMIC that gives rise to "excess inclusion" income as
defined under Section 860E of the Code.
    
 
    If a qualified pension trust (i.e., any pension or other retirement trust
that qualifies under Section 401(a) of the Code) holds more than 10% by value of
the interests in a "pension-held REIT" at any time during a taxable year, a
substantial portion of the dividends paid to the qualified pension trust by such
REIT may constitute UBTI. For these purposes, a "pension-held REIT" is any REIT
(i) that would not have qualified as a REIT but for the provisions of the Code
which look through qualified pension trust stockholders in determining ownership
of stock of the REIT and (ii) in which at least one qualified pension
 
                                       78
<PAGE>
trust holds more than 25% by value of the interests in the REIT or one or more
qualified pension trusts (each owning more than a 10% interest by value in the
REIT) hold in the aggregate more than 50% by value of the interests in the REIT.
Assuming compliance with the Ownership Limit described in "Description of
Capital Stock Restrictions on Ownership and Transfer," it is unlikely that
pension plans will accumulate sufficient stock to cause the Company to be
treated as a pension-held REIT.
 
    Distributions to certain types of stockholders exempt from United States
federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of
the Code may also constitute UBTI, and such prospective investors should consult
their tax advisors concerning the applicable "set aside" and reserve
requirements.
 
STATE AND LOCAL TAXES
 
   
    The Company and its stockholders (including holders of Depositary Shares)
may be subject to state or local taxation in various jurisdictions, including
those in which it or they transact business or reside. The state and local tax
treatment of the Company and its stockholders may not conform to the United
States federal income tax consequences discussed above. Consequently,
prospective holders of the Series A Preferred Shares or the Depositary Shares
should consult their tax advisors regarding the effect of state and local tax
laws on an investment in the Series A Preferred Shares or the Depositary Shares.
    
 
   
TAXATION OF BANK PREFERRED SHARES AND DEPOSITARY SHARES
    
 
   
    Dividends on the Bank Preferred Shares (including any Canadian nonresident
withholding tax with respect thereto) generally will be includible in the gross
income of a holder of the Bank Preferred Shares as ordinary income at the time
such dividends are received. Dividends on the Bank Preferred Shares and,
accordingly, the Depositary Shares will be foreign source income and, subject to
certain limitations and conditions, a holder of the Bank Preferred Shares or the
Depositary Shares will be eligible to claim a foreign tax credit (or,
alternatively, a deduction) in respect of any Canadian nonresident withholding
tax imposed thereon. Dividends on the Bank Preferred Shares and, accordingly the
Depositary Shares will not be eligible for a corporate dividends received
deduction.
    
 
   
    Holders of the Bank Preferred Shares or the Depositary Shares will generally
recognize gain or loss upon the sale or exchange of the Bank Preferred Shares or
the Depositary Shares equal to the difference between the amount realized on the
sale or exchange and the holders' adjusted basis in the Bank Preferred Shares or
the Depositary Shares, respectively. Any gain realized on the sale or exchange
of the Bank Preferred Shares or the Depositary Shares will generally be U.S.
source.
    
 
   
    The Bank does not believe that it is currently, for United States federal
income tax purposes, a passive foreign investment company (a "PFIC"), and does
not expect to become a PFIC in the future. If, however, the Bank does become a
PFIC, holders of the Bank Preferred Shares and, accordingly, the Depositary
Shares could be subject to additional United States federal income tax with
respect to certain distributions on, or gains from the disposition of, the Bank
Preferred Shares or the Depositary Shares.
    
 
CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS APPLICABLE TO FOREIGN
  HOLDERS
 
   
    The following discussion summarizes certain United States federal income tax
consequences of the acquisition, ownership and disposition of the Series A
Preferred Shares or the Depositary Shares by a prospective investor in Series A
Preferred Shares or Depositary Shares that, for United States federal income tax
purposes, is not a "United States person" (a "Non-United States Holder"). For
purposes of this discussion, a "United States person" means: a citizen or
individual resident of the United States; a corporation, partnership, or other
entity created or organized in or under the laws of the United States or of any
political subdivision thereof; an estate the income of which is includible in
gross income for United States federal income tax purposes regardless of its
source; or a trust if both: (i) a United States court is able to exercise
primary supervision over the administration of the trust, and (ii) one or more
United
    
 
                                       79
<PAGE>
   
States persons have the authority to control all substantial decisions of the
trust. This discussion is necessarily of a general nature and does not consider
any specific facts or circumstances that may apply to a particular Non-United
States Holder. Prospective investors are urged to consult their tax advisors
regarding the United States federal tax consequences of acquiring, holding and
disposing of the Series A Preferred Shares or the Depositary Shares as well as
any tax consequences that may arise under the laws of any foreign, state, local
or other taxing jurisdiction.
    
 
   
    DIVIDENDS.  Dividends paid by the Company out of current and accumulated
earnings and profits, as determined for United States federal income tax
purposes, to a Non-United States Holder will generally be subject to withholding
of United States federal income tax at the rate of 30%, unless reduced or
eliminated by an applicable tax treaty or unless such dividends are treated as
effectively connected with a United States trade or business of the Non-United
States Holder. Distributions paid by the Company in excess of its current and
accumulated earnings and profits will be treated first as a nontaxable return of
capital to the extent of the holder's adjusted basis in his Series A Preferred
Shares or Depositary Shares and, thereafter, as gain from the sale or exchange
of a capital asset as described in "Gain on Disposition." If it cannot be
determined at the time a distribution is made whether such distribution will
exceed the current and accumulated earnings and profits of the Company, the
distribution will be subject to withholding at the same rate as dividends.
Amounts so withheld, however, will be refundable or creditable against the Non-
United States Holder's United States federal income tax liability if it is
subsequently determined that such distribution was, in fact, in excess of the
current and accumulated earnings and profits of the Company. If the receipt of a
dividend is treated as being effectively connected with the conduct of a United
States trade or business by a Non-United States Holder, the dividend received by
such holder will be subject to United States federal income tax in the same
manner as United States persons generally (and, in the case of a corporate
holder, possibly the branch profits tax).
    
 
   
    GAIN ON DISPOSITION.  A Non-United States Holder will generally not be
subject to United States federal income tax on gain recognized on a sale or
other disposition of the Series A Preferred Shares or the Depositary Shares
unless (i) the gain is effectively connected with the conduct of a United States
trade or business by the Non-United States Holder, (ii) in the case of a
Non-United States Holder who is a nonresident alien individual and holds the
Series A Preferred Shares or the Depositary Shares, as the case may be, as a
capital asset, such holder is present in the United States for 183 or more days
in the taxable year and certain other requirements are met, or (iii) the Series
A Preferred Shares or the Depositary Shares, as the case may be, constitute
"United States real property interests" ("USRPIs"). The Company does not believe
that the Series A Preferred Shares or the Depositary Shares are, or are likely
to become, USRPIs. Gain that is effectively connected with the conduct of a
United States trade or business by a Non-United States Holder will be subject to
United States federal income tax in the same manner as United States persons
generally (and, in the case of a corporate holder, possibly the branch profits
tax) but will not be subject to withholding. Non-United States Holders should
consult applicable treaties, which may provide for different rules.
    
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
   
    A holder of the Series A Preferred Shares or the Depositary Shares may be
subject to information reporting and to backup withholding at a rate of 31% in
respect of dividends on, or proceeds from the sale or disposition of, the Series
A Preferred Shares or the Depositary Shares. Certain holders of the Series A
Preferred Shares or the Depositary Shares (such as corporations and tax-exempt
entities) are not subject to backup withholding.
    
 
    Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to a holder of the Series A Preferred
Shares or the Depositary Shares will generally be allowed as a refund or a
credit against such holder's United States federal income tax liability,
provided that the required information is furnished to the Internal Revenue
Service.

                   CANADIAN FEDERAL INCOME TAX CONSIDERATIONS
 
    In the opinion of Desjardins Ducharme Stein Monast, the following summary
describes, as of the date hereof, the material Canadian federal income tax
consequences that would generally be applicable to a holder of the Depositary
Shares in the event that the Series A Preferred Shares of the Company are
exchanged for the Bank Preferred Shares pursuant to the Automatic Exchange and,
accordingly, the Depositary Shares represent a one-fortieth interest in a Bank
Preferred Share. See "Description of Series A Preferred Shares--Automatic
Exchange" and "Description of Depositary Shares--Automatic Exchange." The
discussion is based on the assumption that the holder of the Depositary Shares,
for the purpose of the Income Tax Act (Canada) (the "Income Tax Act") and at all
relevant times, is not a resident of Canada, deals at arm's length with the
Bank, does not use or hold and is not deemed to use or hold the Depositary
Shares in carrying on a business in Canada and is not an insurer that carries on
an insurance business in Canada.
 
    This summary is based on the current provisions of the Income Tax Act and
the regulations thereunder, our understanding of the current administrative
practices of Revenue Canada and all specific proposals to amend the Income Tax
Act and the regulations thereunder announced by the Minister of Finance prior to
the date hereof. This summary does not otherwise take into account any changes
in governing law, nor does it take into account tax legislation or
considerations of any province or territory of Canada or any jurisdiction other
than Canada.
 
    This summary is of general nature only and is not intended to be, and should
not be interpreted as, legal or tax advice to any particular holder of the Bank
Preferred Shares. Holders of the Depositary Shares are advised to consult their
own tax advisors with respect to their particular tax position.
 
AUTOMATIC EXCHANGE
 
    In the event of the Automatic Exchange, the exchange will not give rise to
any immediate Canadian income tax consequences to a holder of the Depositary
Shares. The Bank Preferred Shares received or represented by Depositary Shares
pursuant to the Automatic Exchange will have a cost, for Canadian tax purposes,
equal to their fair market value at the time of the Automatic Exchange,
expressed in Canadian dollars.
 
TAXATION OF DIVIDENDS
 
    Dividends paid on the Bank Preferred Shares and, accordingly, the Depositary
Shares to a non-resident of Canada will be subject to Canadian withholding tax
at the general rate of 25% or such lesser rate as may be provided by an
applicable income tax treaty. Pursuant to the Canada-United States Income Tax
Convention (1980) (the "Treaty"), dividends paid by the Bank to a holder of the
Bank Preferred Shares and, accordingly, the Depositary Shares that is resident
in the United States for purposes of the Treaty would generally be subject to
withholding tax at the rate of 15%. Dividends paid to an "Exempt Organization,"
as defined in the Treaty, would generally be exempt from Canadian withholding
tax.
 
DISPOSITION OF BANK PREFERRED SHARES
 
    A disposition or deemed disposition of the Depositary Shares by a resident
of the United States for purposes of the Treaty will generally not result in any
Canadian income or capital gains taxes being payable by the holder.
 
REDEMPTION OF BANK PREFERRED SHARES
 
    A redemption of the Bank Preferred Shares could result in a deemed dividend
to the holder of Depositary Shares, equal to the such holder's proportional
amount based upon the number of Depositary Shares held of the excess of the
amount paid for the Bank Preferred Shares over their paid-up capital. The
 
                                       81
<PAGE>
"paid-up capital" would generally be considered to be the fair market value of
the Series A Preferred Shares received by the Bank at the time of the Automatic
Exchange. A deemed dividend would be subject to Canadian withholding tax, as
described above under "Taxation of Dividends."
 
                              ERISA CONSIDERATIONS
 
    ERISA and the Code impose certain restrictions on (a) employee benefit plans
(as defined in Section 3(3) of ERISA) subject to Title I of ERISA, (b) plans
described in Section 4975(e)(1) of the Code, including individual retirement
accounts or Keogh plans, (c) any entities whose underlying assets include "plan
assets" under the Plan Asset Regulation (as defined below) (each a "Plan") and
(d) persons and entities who have certain specified relationships to such Plans
("Parties-in-Interest" under ERISA and "Disqualified Persons" under the Code).
Moreover, based on the reasoning of the United States Supreme Court in John
Hancock Mutual Life Insurance Co. v. Harris Trust & Savings Bank, 114 S. Ct. 517
(1993), an insurance company's general account may be deemed to include assets
of the Plans investing in the general account (e.g., through the purchase of an
annuity contract), and the insurance company might be treated as a
Party-in-Interest or Disqualified Person with respect to a Plan by virtue of
such investment. ERISA also imposes certain duties on persons who are
fiduciaries of Plans subject to ERISA, and ERISA and the Code prohibit certain
transactions between a Plan and Parties-in-Interest or Disqualified Persons with
respect to such Plan.
 
STATUS UNDER PLAN ASSET REGULATIONS
 
    The Department of Labor has issued a regulation (29 C.F.R. Section
2510.3-101) concerning the definition of what constitutes the assets of a Plan
(the "Plan Asset Regulation"). The Plan Asset Regulation provides that, as a
general rule, the underlying assets and properties of corporations,
partnerships, trusts and certain other entities in which a Plan purchases an
equity interest will be deemed for purposes of ERISA and Section 4975 of the
Code to be assets of the investing Plan unless certain exceptions apply. Under
one such exception, the assets of such an entity are not considered to be Plan
assets where a Plan makes an investment in an equity interest that is a
"publicly-offered security." As described in more detail below, the Company
anticipates that the Series A Preferred Shares and, accordingly, the Depositary
Shares will, following the consummation of the Offering and the Exchange Offer,
be "publicly-offered securities" for purposes of the Plan Asset Regulation.
Prior to the consummation of the Offering and the Exchange Offer, however, it is
anticipated that the Series A Preferred Shares and, accordingly, the Depositary
Shares will not be "publicly-offered securities" and, accordingly, the assets of
the Company may be treated as assets of a Plan that purchases the Series A
Preferred Shares or the Depositary Shares.
 
    Under the terms of the Plan Asset Regulation, if the Company were deemed to
hold plan assets by reason of a Plan's investment in the Series A Preferred
Shares or the Depositary Shares, such plan assets would include an undivided
interest in the assets held by the Company including the Mortgage Assets. In
such event, the persons providing services, or exercising any discretionary
authority or control, with respect to the assets of the Company may become
Parties-in-Interest or Disqualified Persons with respect to such an investing
Plan and may be subject to the fiduciary responsibility provisions of Title I of
ERISA (including the general prohibition against maintaining the indicia of
ownership of Plan assets outside the jurisdiction of the U.S. district courts)
and the prohibited transaction provisions of ERISA and Section 4975 of the Code
with respect to transactions involving such assets. In this regard, if the
person or persons with discretionary responsibilities with respect to the
Mortgage Assets were affiliated with the Company, any such discretionary actions
taken with respect to such Mortgage Assets could be deemed to constitute a
prohibited transaction under ERISA or the Code (e.g., the use of such fiduciary
authority or responsibility in circumstances under which such persons have
interests that may conflict with the interests of the Plans for which they act
and affect the exercise of their best judgment as fiduciaries). In order to
avoid such prohibited transactions or other breaches of fiduciary duty, and to
delineate fiduciary responsibility
 
                                       82
<PAGE>
appropriately, each investing Plan, by purchasing the Series A Preferred Shares
or the Depositary Shares, will be deemed to have (i) approved the Company's
investment in the Initial Mortgage Assets issued by NB Finance (as well as the
other assets held by the Company and identified at the time of purchase) and
(ii) in the event that the Series A Preferred Shares and, accordingly, the
Depositary Shares are not treated as "publicly-offered securities" as of the
dates on which the Offering and the Exchange Offer are consummated, then during
the period commencing on such date and ending on the date on which the Series A
Preferred Shares and, accordingly, the Depositary Shares become
"publicly-offered securities," appointed the Independent Fiduciary (an entity
unaffiliated with and independent of the Bank and the Company) as a fiduciary of
such Plan to exercise any discretionary authority reserved to the Company, to
the extent that the duties of such entity involve discretionary authority or
control respecting transactions with the Bank or the Bank's affiliates. The
Independent Fiduciary will be identified by the Company prior to any such
transaction and will be subject to removal and replacement by a majority of the
holders of the Series A Preferred Shares.
 
    The Company may from time to time invest the proceeds received in connection
with the repayment or disposition of the Initial Mortgage Assets issued by NB
Finance, the issuance of additional shares of Preferred Stock or additional
capital contributions with respect to the Common Stock. To the extent that the
investment of such proceeds occurs prior to the consummation of the Offering and
the Exchange Offer, such proceeds will be invested in Canadian or U.S.
government guaranteed, mortgage-backed certificates and other Canadian or U.S.
government obligations, which will be purchased on the open market or from
entities unaffiliated with the Bank or the Company. In addition, in the event
that the Series A Preferred Shares and, accordingly, the Depositary Shares are
not treated as "publicly-offered securities" as of the date on which the
Offering and the Exchange Offer are consummated, then during the period
commencing on such date and ending on the date on which the Series A Preferred
Shares and, accordingly, the Depositary Shares become "publicly-offered
securities," such proceeds may be invested in additional Mortgage Assets,
provided that, to the extent any such proceeds are invested in Mortgage Assets
in a transaction with the Bank or any Bank affiliate, any discretionary
authority reserved to the Company in respect of such transaction will be
exercised by the Independent Fiduciary.
 
PUBLICLY-OFFERED SECURITY EXCEPTION
 
    For purposes of the Plan Asset Regulation, a "publicly-offered security" is
a security that is (a) "freely transferable," (b) part of a class of securities
that is "widely held," and (c) sold to the Plan as part of an offering of
securities to the public pursuant to an effective registration statement under
the Securities Act and part of a class of securities that is registered under
the Exchange Act within 120 days (or such later time as may be allowed by the
Commission) after the end of the fiscal year of the issuer during which the
offering of such securities to the public occurred. It is anticipated that, in
connection with the Offering and the Exchange Offer, the Series A Preferred
Shares and the Depositary Shares will be registered under the Securities Act and
the Exchange Act within the time periods specified in the Plan Asset Regulation.
 
    The Plan Asset Regulation provides that a security is "widely held" only if
it is a part of the class of securities that is owned by 100 or more investors
independent of the issuer and of one another. A security will not fail to be
"widely held" because the number of independent investors falls below 100
subsequent to the initial offering as a result of events beyond the control of
the issuer. The Company anticipates that the Series A Preferred Shares and the
Depositary Shares will be "widely held" upon the consummation of the Offering
and the Exchange Offer.
 
    The Plan Asset Regulation provides that whether a security is "freely
transferable" is a factual question to be determined on the basis of all the
relevant facts and circumstances. The Plan Asset Regulation further provides
that when a security is part of an offering in which the minimum investment is
US$10,000 or less, as is expected to be the case with respect to the Offering
and the Exchange Offer, certain restrictions ordinarily will not, alone or in
combination, affect the finding that such securities are "freely transferable."
The Company believes that any restrictions imposed on the transfer of the Series
A
 
                                       83
<PAGE>
Preferred Shares and the Depositary Shares following the consummation of the
Offering and the Exchange Offer will be limited to the restrictions on transfer
generally permitted under the Plan Asset Regulation and are not likely to result
in the failure of the Series A Preferred Shares and the Depositary Shares to be
"freely transferable."
 
EXEMPTIONS FROM PROHIBITED TRANSACTIONS
 
    Any purchaser that is an insurance company using the assets of an insurance
company general account should note that the Small Business Job Protection Act
of 1996 added new Section 401(c) of ERISA relating to the status of the assets
of insurance company general accounts under ERISA and Section 4975 of the Code.
Pursuant to Section 401(c), the Department of Labor is required to issue final
regulations (the "General Account Regulations") with respect to insurance
policies issued on or before December 31, 1998 that are supported by an
insurer's general account. The General Account Regulations, which were issued in
proposed form on December 22, 1997, are to provide guidance on which assets held
by the insurer constitute "Plan Assets" for purposes of the fiduciary
responsibility provisions of ERISA and Section 4975 of the Code. Section 401(c)
also provides that, except in the case of avoidance of the General Account
Regulations and actions brought by the Secretary of Labor relating to certain
breaches of fiduciary duties that also constitute breaches of state or federal
criminal law, until the effective dates of the General Account Regulations, no
liability under the fiduciary responsibility and prohibited transaction
provisions of ERISA and Section 4975 of the Code may result on the basis of a
claim that the assets of the general account of an insurance company constitute
Plan Assets. The Plan Asset status of insurance company separate accounts is
unaffected by new Section 401(c) of ERISA, and separate account assets continue
to be treated as the assets of any Plan invested in a separate account except to
the extent provided in the Plan Asset Regulation.
 
    In addition, if the Bank or the Depositary, or in certain circumstances an
obligor with respect to a Mortgage Asset or other debt instrument held by the
Company, is a Party-in-Interest or Disqualified Person with respect to an
investing Plan, such Plan's investment could be deemed to constitute a
transaction prohibited under Title I of ERISA or Section 4975 of the Code (e.g.,
the extension of credit or sale of property between a Plan and a
Party-in-Interest or Disqualified Person). Such transactions may, however, be
subject to a statutory or administrative exemption such as Prohibited
Transaction Class Exemption ("PTCE") 90-1, which exempts certain transactions
involving insurance company pooled separate accounts; PTCE 95-60, which exempts
certain transactions involving insurance company general accounts; PTCE 91-38,
which exempts certain transactions involving bank collective investment funds;
PTCE 84-14, which exempts certain transactions effected on behalf of a Plan by a
"qualified professional asset manager"; and PTCE 96-23, which exempts certain
transactions effected on behalf of a Plan by an "in-house asset manager"; or
pursuant to any other available exemption. Such exemptions may not, however,
apply to all of the transactions that could be deemed prohibited transactions in
connection with such Plan's investment.
 
    Each investor in Series A Preferred Shares or Depositary Shares will be
deemed to have represented and agreed that either (i) no part of the assets to
be used by it to acquire and hold such Series A Preferred Shares or Depositary
Shares constitutes the assets of any Plan or (ii) one or more prohibited
transaction statutory or class exemptions applies such that the use of such
assets to acquire and hold the Series A Preferred Shares or Depositary Shares
will not constitute a non-exempt prohibited transaction under ERISA or the Code.
Any Plan fiduciary that proposes to cause a Plan to acquire Series A Preferred
Shares or the Depositary Shares should consult with its counsel with respect to
the potential applicability of ERISA and the Code to such investment and whether
any exemption would be applicable and determine on its own whether all
conditions of such exemption or exemptions have been satisfied such that the
acquisition and holding of Series A Preferred Shares or the Depositary Shares by
the purchaser Plan are entitled to the full exemptive relief thereunder. Any
such Plan fiduciary should also determine whether the investment in Series A
Preferred Shares or the Depositary Shares is permitted under the governing Plan
 
                                       84
<PAGE>
instruments and is appropriate for the Plan in view of the overall investment
policy and the composition and diversification of its portfolio.
 
UNRELATED BUSINESS TAXABLE INCOME
 
    Plan fiduciaries should also consider the consequences of holding more than
10% of the Series A Preferred Shares if the Company is "predominantly held" by
qualified trusts. See "United States Federal Income Tax Considerations Treatment
of Tax-Exempt Entities."
 
                                    RATINGS
 
    The Series A Preferred Shares are rated "a2" by Moody's Investors Service,
Inc. and "BBB+" by Standard & Poor's Ratings Services. A security rating is not
a recommendation to buy, sell or hold securities and may be subject to revision
or withdrawal at any time by the assigning rating organization. No person is
obligated to maintain any rating on the Series A Preferred Shares, and,
accordingly, there can be no assurance that the ratings assigned to the Series A
Preferred Shares will not be lowered or withdrawn by the assigning rating
organization at any time thereafter.
 
                               INITIAL PURCHASER
 
   
    The Series A Preferred Shares were originally purchased by the Initial
Purchaser in a transaction exempt from the registration requirements of the
Securities Act, to persons reasonably believed by such Initial Purchaser to be
"qualified institutional buyers" (as defined in Rule 144A under the Securities
Act), to certain qualified institutional buyers acting on behalf of
institutional "accredited investors" (as defined in Rule 501(a) (1), (2), (3) or
(7) under the Securities Act), or outside the United States to non-U.S. persons
in offshore transactions in reliance on Regulation S under the Securities Act.
The Series A Preferred Shares were registered under the Securities Act pursuant
to (i) a Registration Statement on Form S-11/F-9 and (ii) a Registration
Statement on Form S-4/F-9, each declared effective by the Commission on March 2,
1998.
    
 
   
    As of April 22, 1998, the Initial Purchaser held of record 61,600 Series A
Preferred Shares or approximately 20.5% of the outstanding Series A Preferred
Shares. If the Initial Purchaser were to exchange all of such shares for
Depositary Shares, it would receive 2,464,000 Depositary Shares. The number of
Depositary Shares to be offered by the Initial Purchaser is subject to change at
any time since the Initial Purchaser may buy and sell Series A Preferred Shares
in the open market. This Prospectus may be used by the Initial Purchaser to sell
Depositary Shares and Series A Preferred Shares.
    
 
    The Initial Purchaser does not, and has never had, any position, office or
other material relationship with the Company or any of its affiliates. Because
the Initial Purchaser may, pursuant to this Prospectus, offer all or some
portion of the Depositary Shares, no estimate can be given as to the amount of
the Depositary Shares that will be held by the Initial Purchaser upon
termination of any such sales.
 
                              PLAN OF DISTRIBUTION
 
   
    The Series A Preferred Shares and the Depositary Shares held by the Initial
Purchaser may be sold from time to time to purchasers directly by the Initial
Purchaser. Alternatively, the Initial Purchaser may from time to time offer the
Series A Preferred Shares and the Depositary Shares to or through underwriters,
brokers/dealers or agents, who may receive compensation in the form of
underwriting discounts, concessions or commissions from the Initial Purchaser or
the purchasers of such securities for whom they may act as agents. The Initial
Purchaser and any underwriters, broker/dealers or agents that participate in the
distribution of Series A Preferred Shares and the Depositary Shares may be
deemed to be "underwriters" within the meaning of the Securities Act and any
profit on the sale of such securities and any discounts, commissions,
concessions or other compensation received by any such underwriter, broker/
dealer or agent may be deemed to be underwriting discounts and commissions under
the Securities Act.
    
 
                                       85
<PAGE>
   
    The Series A Preferred Shares and the Depositary Shares may be sold from
time to time in one or more transactions at fixed prices, at prevailing market
prices at the time of sale, at varying prices determined at the time of sale or
at negotiated prices. The sale of the Series A Preferred Shares and the
Depositary Shares may be effected in transactions (which may involve crosses or
block transactions) (i) on any national securities exchange or quotation service
on which the Series A Preferred Shares and the Depositary Shares may be listed
or quoted at the time of sale, (ii) in the over-the-counter market, (iii) in
transactions otherwise than on such exchanges or in the over-the-counter market
or (iv) through the writing of options. At the time a particular offering of the
Series A Preferred Shares and the Depositary Shares is made, a supplement to
this Prospectus, if required, will be distributed which will set forth the
aggregate amount being offered and the terms of the offering, including the name
or names of any underwriters, broker/dealers or agents, any discounts,
commissions and other terms constituting compensation from the Initial Purchaser
and any discounts, commissions or concessions allowed or re-allowed or paid to
broker/dealers.
    
 
   
    The Initial Purchaser will be subject to applicable provisions of the
Exchange Act and the rules and regulations thereunder, which provisions may
limit the timing of purchases and sales of any of the Series A Preferred Shares
and the Depositary Shares by the Initial Purchaser. The foregoing may affect the
marketability of such securities.
    
 
   
    Pursuant to the Deposit Agreement, the expenses of the registration of the
Depositary Shares will not be paid by the holders thereof, including, without
limitation, Commission filing fees and expenses of compliance with state
securities or "blue sky" laws; provided, however, that the Initial Purchaser
will pay all underwriting discounts and selling commissions, if any. The
Depositary will be indemnified against certain civil liabilities, including
certain liabilities under the Securities Act, or will be entitled to
contribution in connection therewith. The Company will be indemnified against
certain civil liabilities, including certain liabilities under the Securities
Act, or will be entitled to contribution in connection therewith.
    
 
   
    This Prospectus, as it may be amended or supplemented from time to time, may
be used by a broker-dealer in connection with resales of Series A Preferred
Shares received pursuant to the Exchange Offer in exchange for Series A
Preferred Shares then outstanding ("Old Preferred Shares") where such Old
Preferred Shares were acquired as a result of market-making activities or other
trading activities as well as Depositary Shares representing such Series A
Preferred Shares. To the extent any such broker-dealer participated in the
Exchange Offer, the Company has agreed that, for a period of up to six months
after the date of this Prospectus, it will make this Prospectus, as amended or
supplemented, available to such broker-dealer for use in connection with any
such resale of Series A Preferred Shares and, accordingly, Depositary Shares
representing such Series A Preferred Shares, will update this Prospectus, as
required, during such six-month period and will promptly send additional copies
of this Prospectus and any amendment or supplement to this Prospectus to any
broker-dealer that requests such documents.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of NB Capital Corporation
 
    We have audited the accompanying balance sheet of NB Capital Corporation as
of December 31, 1997 and the related statements of income, stockholders' equity
and cash flows for the period August 20, 1997 (date of incorporation) to
December 31, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
    We conducted our audit in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.
 
    In our opinion, these financial statements present fairly, in all material
respects, the financial position of the Company as of December 31, 1997 and the
results of its operations and its cash flows for the period August 20, 1997
(date of incorporation) to December 31, 1997, in conformity with accounting
principles generally accepted in the United States of America.

Notes to the financial statements
For the period August 20, 1997 (date of incorporation) to December 31, 1997
(in U.S. dollars)
 
- --------------------------------------------------------------------------------
 
1.  INCORPORATION AND NATURE OF OPERATIONS
 
    NB Capital Corporation (the "Company") was incorporated in the state of
Maryland on August 20, 1997. The Company's principal business is to acquire,
hold, finance and manage mortgage assets. The Company issued, through an
Offering Circular dated August 22, 1997, $300 million of preferred stock and
simultaneously, National Bank of Canada, the parent company, made a capital
contribution in the amount of $183 million. The Company used the aggregate net
proceeds of $477 million to acquire promissory notes of NB Finance, Ltd., a
wholly-owned subsidiary of National Bank of Canada.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
    FINANCIAL STATEMENTS
 
    The financial statements are prepared in accordance with accounting
principles generally accepted in the United States of America and are expressed
in U.S. dollars.
 
    INCOME TAXES
 
    The Company upon filing its initial tax return will elect to be taxable as a
Real Estate Investment Trust ("REIT") under the Internal Revenue Code of 1986,
as amended, and accordingly generally will not be liable for United States
federal income tax to the extent that it distributes at least 95% of its taxable
income to its stockholders, maintains its qualification as a REIT and complies
with certain other requirements (see Note 6).
 
    PER SHARE DATA
 
    Basic earnings per share with respect to the Company for the four-month
period ended December 31, 1997 are computed based upon the weighted average
number of common shares outstanding during the period. In February 1997, the
Financial Accounting Standards Board issued Statement of Financial Accounting
Standard No. 128 "Earnings Per Share". This pronouncement specifies the
computation, presentation and disclosure requirements for earnings per share.
The Company has no outstanding securities which are dilutive under this
pronouncement.
 
    ESTIMATES
 
    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
3.  PROMISSORY NOTES
 
    On September 3, 1997, the Company entered into loan agreements evidenced by
promissory notes of NB Finance, Ltd., an affiliated company. The promissory
notes are collateralized only by mortgage loans which are secured by residential
first mortgages and insured by the Canada Mortgage and Housing Corporation.

(IN U.S. DOLLARS)
 
- --------------------------------------------------------------------------------
 
3.  PROMISSORY NOTES (CONTINUED)
    The promissory notes consist of 16 notes with maturities ranging from
January 2000 to July 2001, at rates ranging from 6.90% to 9.77%, with an average
rate of approximately 8.40% per annum.
 
    These rates approximate market interest rates for loans of similar credit
and maturity provisions and, accordingly, management believes that the carrying
value of the promissory notes receivable approximates their fair value.

(IN U.S. DOLLARS)
 
- --------------------------------------------------------------------------------
 
1. INCORPORATION AND NATURE OF OPERATIONS
 
    NB Finance, Ltd. (the "Company") is a wholly-owned subsidiary of National
Bank of Canada and was incorporated in Bermuda on September 3, 1997. The
Company's principal activity is holding mortgage loans.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    FINANCIAL STATEMENTS
 
    The financial statements are prepared in accordance with generally accepted
accounting principles in Canada and are expressed in U.S. dollars.
 
    MORTGAGE LOANS
 
    Mortgage loans are recorded at their principal amounts less allowances for
credit losses.
 
    ESTIMATES
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Although these estimates are based on management's best
knowledge of current events and actions that the Company may undertake in the
future, actual results could differ from the estimates.
 
    TRANSLATION OF FOREIGN CURRENCIES
 
    Monetary assets and liabilities denominated in foreign currencies are
translated into U.S. dollars at year-end rates of exchange. Revenue and expense
items are translated at rates prevailing at the transaction dates. Gains and
losses resulting from translation are reflected in the statement of income.
 
    DERIVATIVE FINANCIAL INSTRUMENTS
 
    The Company used cross currency swaps to manage the currency risk exposure
of the mortgage loans. The gains and losses resulting from the valuation of
these instruments are deferred and amortized to income over the life of the
hedged assets.
 
    INCOME TAXES
 
    The Company does not pay any income taxes on the Bermuda income.
 
    PREMIUM PAID ON MORTGAGE LOANS
 
    The premium paid on mortgage loans is amortized on a straight-line basis
over a three-year period.

dollars from National Bank of Canada. The mortgage loans are secured by
residential first mortgages and insured by the Canada Mortgage and Housing

8.99% with an average rate of 7.53% per annum.

exposure of the mortgage loans to U.S. dollars. The maturity dates of the cross
currency swaps agree with the maturity dates of the mortgage loans.

              8.45% NONCUMULATIVE FIRST PREFERRED SHARES, SERIES Z
 
    The 8.45% Noncumulative First Preferred Shares, Series Z (the "Series Z
Preferred Shares") of National Bank of Canada ("National Bank" or the "Bank"),
will be issued only upon the automatic exchange (see "Automatic Exchange") of
the 8.35% Noncumulative Exchangeable Preferred Stock, Series A (the "Old
Preferred Shares") of NB Capital Corporation, a U.S. subsidiary of the Bank,
and/or of the 8.35% Noncumulative Exchangeable Preferred Stock, Series A (the
"New Preferred Shares") of NB Capital Corporation into which the Old Preferred
Shares are exchangeable (see "Exchange Offer") upon the occurrence of certain
events.
 
    Dividends on the Series Z Preferred Shares will be payable at a rate of
8.45% per annum if, when and as declared by the Board of Directors of the Bank.
For a description of the terms of the Series Z Preferred Shares, see
"Description of the Series Z Preferred Shares" herein.
 
    The Bank currently has outstanding, and may in the future issue, various
other series of first preferred shares (the "Other Series of First Preferred
Shares"). See "Capitalization." The Series Z Preferred Shares will constitute a
new series of first preferred shares of the Bank and will rank PARI PASSU in
terms of cash dividend payment and liquidation preference with the Other Series
of First Preferred Shares (the Series Z Preferred Shares and the Other Series of
First Preferred Shares collectively, the "Preferred Shares"). The Preferred
Shares rank, in priority of payment of dividends and rights upon the voluntary
or involuntary dissolution, liquidation or winding-up of the Bank, junior to all
claims of the Bank's creditors, including the claims of the Bank's depositors
and holders of the Bank's outstanding subordinated debentures. The Preferred
Shares rank superior and prior to the issued and outstanding Common Shares of
the Bank with respect to dividend rights and rights upon voluntary or
involuntary dissolution, liquidation or winding up of the Bank, and to all other
classes and series of shares of the Bank hereafter issued, other than any class
or series expressly designated as being on parity with or senior to the
Preferred Shares. The Common Shares of the Bank constitute the only class of
shares currently outstanding other than the Preferred Shares.
 
    In the event the Old Preferred Shares and/or New Preferred Shares are
exchanged into Series Z Preferred Shares, the Bank does not intend to apply for
the listing of the Series Z Preferred Shares on any national securities exchange
in Canada or the United States or for quotation through the National Association
of Securities Dealers Automated Quotation System.
 
- --------------------------------------------------------------------------------
 
    The Old Preferred Shares and/or New Preferred Shares are exchangeable, if
ever, at the rate of one Series Z Preferred Share for each Old Preferred Share
or New Preferred Share tendered.

    The Bank is a Canadian issuer that is permitted, under a multijurisdictional
disclosure system adopted by the United States, to prepare this short form
prospectus in accordance with the disclosure requirements of its home country.
Prospective investors should be aware that such requirements are different from
those of the United States. The consolidated financial statements included or
incorporated by reference herein have been prepared in accordance with Canadian
generally accepted accounting principles, and thus may not be comparable to
financial statements of United States companies, and are subject to Canadian
auditing and auditor independence standards which differ from standards in the
United States.
 
    Prospective investors should be aware that the acquisition of the securities
described herein may have tax consequences both in the United States and in
Canada. Such consequences for investors who are residents in, or citizens of,
the United States may not be described fully herein.
 
    The enforcement by investors of civil liabilities under the federal
securities laws of the United States may be affected adversely by the fact that
the Bank is incorporated or organized under the laws of Canada, that some or all
of its officers and directors may be residents of Canada, that some or all of
the experts named in the registration statement may be residents of Canada and
that all or a significant portion of the assets of the Bank and said persons may
be located outside the United States.

               ENFORCEMENT OF LIABILITIES AND SERVICE OF PROCESS
 
    National Bank of Canada is a Canadian bank; all of the directors and
executive officers of the Bank and certain of the Bank's advisers named in this
short form prospectus are residents of countries other than the United States of
America ("U.S."); and all or a substantial portion of the assets of such
non-U.S. residents are located outside the U.S. As a result, it may not be
possible for investors to effect service of process within the U.S. upon such
persons or to enforce against them in the U.S. judgments of U.S. Courts
predicated upon the civil liability provisions of the federal securities laws of
the U.S. The Bank will expressly accept the jurisdiction of the Supreme Court of
the State of New York or the U.S. District Court for the Southern District of
New York, in either case in the Borough of Manhattan, The City of New York, for
the purpose of any suit, action or proceeding arising out of the Series Z
Preferred Shares offered hereby, and has appointed NB Capital Corporation, a
subsidiary of the Bank, as its agent in The City of New York to accept service
of process in any such action. The Bank has been advised by Desjardins Ducharme
Stein Monast, Canadian counsel to the Bank, that there is doubt as to the
enforceability in the Province of Quebec, in original actions or in actions for
enforcement of judgments of U.S. Courts, of liabilities predicated solely upon
the federal securities laws of the U.S.

    Through its network of 637 branches at October 31, 1997, Retail Banking
provides services to individuals and serves as support to the commercial banking
centres and the Corporate Banking, International Commercial Operations and
Treasury divisions.
 
    In addition to personal and mortgage loans, the Bank offers a broad range of
transaction accounts and investment vehicles, such as term deposits and
investment certificates, mutual funds (managed by the Bank or by third parties)
and registered retirement savings plans and income funds, as well as credit card
and travelers cheque services. In response to clients' growing demand for
financial advisory services, the Bank embarked on a new phase in 1996 when it
integrated more than 50 accredited financial planners into its branches.

through the Interac Direct Payment network, debit card holders can pay for their
purchases without using cash at any of the Bank's 28,337 point-of-sale
terminals.
 
    The Bank continues to assume a leadership role in customer service by
offering its customers non-traditional services such as TelNat for banking by
phone and Personal CompuTeller for banking by computer. The first service of its
kind in Canada, Personal CompuTeller gives customers direct access to their
transaction accounts via their personal computer.

services, the Bank developed another delivery concept in the form of specially
designed service units in supermarkets, open seven days a week.

services a small number of business clients, and by experts in special financing
methods. In addition to the specialized services offered by Treasury and

variable-rate term loans, as well as computerized payroll processing, bank

services for establishing foreign trade or an international strategy.
 
    The International division has also made its presence felt abroad through
its representative offices in New York, the Caribbean, Mexico, Santiago, London,
Paris, Hong Kong, Seoul, Singapore, Taiwan and Shanghai; cooperation agreements
with seven European financial institutions and a Mexican bank; and via a vast
network of some 2,800 banking correspondents spanning 120 countries.
 
    Through this presence abroad, the International division can serve its
clientele which includes Canadian clients, foreign companies, international
banks which obtain traditional services such as correspondent banking, and
immigrant investors to whom the Bank provides private banking services as well
as other products designed specifically to meet their needs.
 
    The Bank has also developed partnerships with private enterprise and all
three levels of public administration. Partnerships created in 1996 include the
Action Asia Group, Montreal International, the Canada-Poland Development Fund
and a France-Quebec network for independent businesses, as well as the agreement
to accommodate Quebec trade delegates in the Bank's offices in Boston, Los
Angeles, Chicago and Atlanta.

                  DESCRIPTION OF THE SERIES Z PREFERRED SHARES
 
    The following is a summary of the rights, privileges, restrictions and
conditions of the First Preferred Shares as a class and of the Series Z
Preferred Shares as a series.
 
CERTAIN PROVISIONS OF THE FIRST PREFERRED SHARES AS A CLASS
 
    The authorized first preferred share capital of the Bank consists of an
unlimited number of First Preferred Shares, without par value, which may be
issued for a maximum aggregate consideration of $1,000,000,000 or the equivalent
thereof in foreign currencies. The Board of Directors of the Bank may by
resolution divide any unissued First Preferred Shares into series and fix the
number of shares in each series and determine the designation, rights,
privileges, restrictions and conditions thereof.
 
PRIORITY
 
    The First Preferred Shares of each series will rank on a parity with First
Preferred Shares of every other series and are entitled to preference over the
Common Shares, and any other shares of the Bank ranking junior to the First
Preferred Shares with respect to the payment of dividends and upon any
distribution of assets in the event of liquidation, dissolution or winding-up of
the Bank.
 
RESTRICTION
 
    The Bank will not, without the approval of the holders of the First
Preferred Shares, create or issue any shares ranking in priority to or PARI
PASSU with the First Preferred Shares, nor create or issue any additional series
of First Preferred Shares, unless all cumulative dividends have been declared
and paid or set aside for payment and all declared and unpaid non-cumulative
dividends have been paid or set aside for payment.
 
VOTING RIGHTS
 
    The Board of Directors is empowered to set voting rights for each series.
The holders of the First Preferred Shares are not entitled to any voting rights
as a class except as provided above or by law or with respect to the right to
vote on certain matters as specified under "Approval of the Holders of the First
Preferred Shares."
 
APPROVAL OF THE HOLDERS OF THE FIRST PREFERRED SHARES
 
    The provisions with respect to First Preferred Shares will not be deleted or
modified except with a resolution carried by the affirmative vote of not less
than 66 2/3% of the votes cast at a meeting of holders of First Preferred Shares
at which a majority of the outstanding First Preferred Shares is represented or,
if no quorum is present at such meeting, at any adjourned meeting at which no
quorum requirements would apply.
 
CERTAIN PROVISIONS OF THE SERIES Z PREFERRED SHARES AS A SERIES
 
    ISSUE PRICE
 
    The Series Z Preferred Shares will have an issue price of U.S.$1,000 per
share.
 
DIVIDENDS
 
    Holders of Series Z Preferred Shares shall be entitled to receive, if, when
and as declared by the Board of Directors of the Bank out of assets of the Bank
legally available therefor, non-cumulative preferential cash dividends at the
rate of 8.45% per annum of the liquidation preference (equivalent to U.S.$1,000
per share). If declared, dividends on the Series Z Preferred Shares shall be
payable quarterly in
 
                                      A-9
<PAGE>
arrears on the 30th day of March, June, September and December of each year, or,
if such day is not a business day, on the next business day. Each declared
dividend shall be payable to holders of record as they appear at the close of
business on the share register of the Bank on such record dates, not exceeding
45 days preceding the payment dates thereof, as shall be fixed by the Board of
Directors of the Bank.
 
    If, within 21 days after the expiration of any financial year of the Bank,
the Board of Directors has not declared any dividend or part thereof on the
Series Z Preferred Shares for such year, then the right of the holders of the
Series Z Preferred Shares to such dividend or part thereof for such year shall
be extinguished.
 
RESTRICTIONS ON DIVIDENDS AND RETIREMENT OF SHARES
 
    As long as any of the Series Z Preferred Shares are outstanding, the Bank
shall not, without the prior approval of the holders of such Series Z Preferred
Shares given as specified below:
 
        (a) declare or pay or set aside for payment any dividends on any shares
    of any class of shares of the Bank ranking junior to the Series Z Preferred
    Shares (other than stock dividends ranking junior to the Series Z Preferred
    Shares);
 
        (b) call for redemption or redeem, call for purchase or purchase, or
    otherwise retire or reduce or make any return of capital in respect of
    shares of any class of shares of the Bank ranking junior to the Series Z
    Preferred Shares;
 
        (c) call for redemption or redeem, call for purchase or purchase, or
    otherwise retire or reduce or make any return of capital in respect of part
    only of the Series Z Preferred Shares; or
 
        (d) call for redemption or redeem, call for purchase or purchase, or
    otherwise retire or reduce or make any return of capital in respect of any
    shares of any class of shares of the Bank ranking PARI PASSU with the Series
    Z Preferred Shares, except in satisfaction of an obligation to purchase or
    obligation in respect of a sinking fund, of a right of retraction or of any
    other mandatory redemption provision of any given series of any preferred
    shares;
 
unless all dividends up to and including the dividend payment date for the last
completed period for which dividends shall be payable shall have been declared
and paid or set apart for payment in respect of each series of cumulative first
preferred shares then issued and outstanding and on all other cumulative shares
ranking on a parity with the First Preferred Shares and there shall have been
paid or set apart for payment all declared dividends in respect of each series
of non-cumulative First Preferred Shares (including the Series Z Preferred
Shares) then issued and outstanding and on all other non-cumulative shares
ranking on a parity with the First Preferred Shares.
 
REDEMPTION
 
    The Series Z Preferred Shares will not be redeemable prior to September 3,
2007. On or after such date, but subject to the provisions of the Bank Act,
including the requirements of the prior consent of the Superintendent, the
Series Z Preferred Shares will be redeemable at the option of the Bank, in whole
or in part, at any time or from time to time on not less than 30 nor more than
60 days' notice by mail, at the following redemption prices (expressed as a
percentage of the $1,000 per share liquidation preference), if
 
                                      A-10

redeemed during the 12-month period beginning September 3 of the years indicated

any, thereon:

and thereafter at a redemption price of $1,000 per share, plus the quarterly
accrued and unpaid dividend to the redemption date, if any, thereon.
 
    If there are any accrued and unpaid dividends on any Series Z Preferred
Shares, no Series Z Preferred Shares shall be redeemed unless all outstanding
Series Z Preferred Shares are redeemed and the Bank shall not purchase or
otherwise acquire any Series Z Preferred Shares; provided, however, that the
Bank may purchase or acquire Series Z Preferred Shares pursuant to a purchase or
exchange offer made on the same terms to holders of all outstanding Series Z
Preferred Shares.
 
    In the event that fewer than all the outstanding Series Z Preferred Shares
are to be redeemed, the number of Series Z Preferred Shares to be redeemed shall
be determined by the Board of Directors, and the shares to be redeemed shall be
determined by lot or proportionately as may be determined by the Board of
Directors or by any other method as may be determined by the Board of Directors
in its sole discretion to be equitable.
 
VOTING RIGHTS
 
    The holders of the Series Z Preferred Shares as such will not be entitled to
receive notice of or to attend or to vote at any meeting of the shareholders of
the Bank unless and until the first time at which the rights of such holders to
any undeclared dividends have become extinguished as described under
"Dividends."
 
    In that event, the holders of the Series Z Preferred Shares will be entitled
to receive notice of, and to attend, meetings of shareholders at which directors
are elected and will be entitled to one vote for each share held. The voting
rights of the holders of the Series Z Preferred Shares shall forthwith cease
upon payment by the Bank of the first quarterly dividend on the Series Z
Preferred Shares to which the holders are entitled subsequent to the time such
voting rights first arose. At such time as the rights of such holders to any
undeclared dividends on the Series Z Preferred Shares have again become
extinguished, such voting rights shall become effective again and so on from
time to time.
 
RIGHTS UPON LIQUIDATION
 
    In the event of any voluntary or involuntary liquidation, dissolution or
winding-up of the Bank, the holders of the Series Z Preferred Shares at the time
outstanding will be entitled to receive out of assets of the Bank legally
available for distribution to shareholders, under applicable law, before any
distribution of assets is made to holders of Common Shares or any other class of
shares ranking junior to the Series Z Preferred Shares upon liquidation, and
subject to the rights of the holders of any class or series of equity securities
having preference with respect to distribution upon liquidation and the rights
of the Bank's
 
                                      A-11
<PAGE>
general creditors, an amount of $1,000 per share, plus the quarterly accrued and
unpaid dividend thereon, if any, to, but excluding, the date of liquidation.
 
    After payment of the full amount of said amount to which they are entitled,
the holders of Series Z Preferred Shares will have no right or claim to any of
the remaining assets of the Bank. In the event that, upon any such voluntary or
involuntary liquidation, dissolution or winding-up, the available assets of the
Bank are insufficient to pay the amount of the liquidation distributions on all
outstanding Series Z Preferred Shares and the corresponding amounts payable on
all shares of other classes or series of share capital of the Bank ranking on a
parity with the Series Z Preferred Shares in the distribution of assets upon any
liquidation, dissolution or winding-up of the affairs of the Bank, then the
holders of the Series Z Preferred Shares and such other classes or series of
share capital shall share ratably in any such distribution of assets in
proportion to the full liquidation distributions to which they would otherwise
be respectively entitled.
 
    For such purposes, the consolidation or merger of the Bank with or into any
other entity, or the sale, lease or conveyance of all or substantially all of
the property or business of the Bank, shall not be deemed to constitute
liquidation, dissolution or winding-up of the Bank.
 
TAXATION
 
    To the extent that dividends on the Series Z Preferred Shares are subject to
Canadian non-resident withholding tax, the Bank will pay such additional amounts
as may be necessary in order that the net amounts received by U.S. holders of
the Series Z Preferred Shares shall equal the amounts which would have been
received thereon in the absence of such tax.
 
                                 COMMON SHARES
 
    The authorized Common Share capital of the Bank consists of an unlimited
number of Common Shares without par value, issuable for a maximum aggregate
consideration of $3 billion, of which 170,461,483 Common Shares were outstanding
as at October 31, 1997.
 
    The holders of Common Shares are entitled to receive dividends as and when
declared by the Board of Directors of the Bank, subject to the preference of
holders of First Preferred Shares. Subject to the restrictions set forth in
"Restraints on Bank Shares under the Bank Act," a holder of Common Shares is
entitled to one vote for each share at all meetings of shareholders except
meetings at which only holders of a specified class or series are entitled to
vote. In the event of the liquidation, dissolution or winding-up of the Bank,
after payment of all outstanding debts and subject to the preference of the
holders of First Preferred Shares, the remaining assets of the Bank would be
distributed proportionately to the holders of Common Shares.
 
                                USE OF PROCEEDS
 
    The Series Z Preferred Shares are to be issued only, if ever, in connection
with the automatic exchange of the Old Preferred Shares and/or New Preferred
Shares into which the Old Preferred Shares are exchangeable pursuant to the
Exchange Offer. The proceeds from the sale of the Old Preferred Shares were used
by NB Capital Corporation to acquire a portfolio of mortgage related assets. The
automatic exchange of Old Preferred Shares and/or New Preferred Shares into
Series Z Preferred Shares will produce no proceeds to the Bank.
 
                               THE EXCHANGE OFFER
 
    Simultaneously with the filing of this short form prospectus by the Bank, NB
Capital Corporation, a 100% controlled subsidiary of the Bank, is offering to
exchange (the "Exchange Offer") up to 300,000 shares of its 8.35% Noncumulative
Exchangeable Preferred Stock, Series A (the "New Preferred Shares")
 
                                      A-12
<PAGE>
for up to all of its outstanding 8.35% Noncumulative Exchangeable Preferred
Stock, Series A (the "Old Preferred Shares") at the rate of one New Preferred
Share for each Old Preferred Share tendered. The issuance of the New Preferred
Shares is intended to satisfy certain obligations of NB Capital Corporation
contained in the Registration Rights Agreement.
 
                         REGISTRATION RIGHTS AGREEMENT
 
    The Old Preferred Shares were sold by NB Capital Corporation on September 3,
1997 to Merrill Lynch, Pierce, Fenner & Smith Incorporated as initial purchaser
(the "Initial Purchaser") pursuant to the purchase agreement among NB Capital
Corporation, the Bank and the Initial Purchaser (the "Purchase Agreement").
Pursuant to the Purchase Agreement, NB Capital Corporation and the Initial
Purchaser entered into the Registration Rights Agreement on September 3, 1997.
Pursuant to the Registration Rights Agreement, the Bank and NB Capital
Corporation agreed to each file a registration statement within a certain time
period and to use their best efforts to cause such registration statements to
become effective within an additional time period with respect to the Exchange
Offer. If certain events do not permit NB Capital Corporation to effect the
Exchange Offer on the terms set forth therein, the Bank and NB Capital
Corporation will use their best efforts to cause to become effective shelf
registration statements with respect to the resale of the Old Preferred Shares
and of the Series Z Preferred Shares and to keep the shelf registration
statements effective until two (2) years after the issue date of the Old
Preferred Shares or such shorter period ending when all of the Old Preferred
Shares have been sold thereunder.
 
                               AUTOMATIC EXCHANGE
 
    The Series Z Preferred Shares are to be issued, if ever, in connection with
an automatic exchange of the Old Preferred Shares and/or New Preferred Shares
into which the Old Preferred Shares are exchangeable pursuant to the Exchange
Offer. The Old Preferred Shares and/or New Preferred Shares are subject to an
automatic exchange in whole and not in part, on a share-for-share basis, into
Series Z Preferred Shares (i) immediately prior to such time, if any, at which
the Bank fails to declare and pay or set aside for payment when due any dividend
on any issue of cumulative First Preferred Shares or the Bank fails to pay or
set aside for payment when due any declared dividend on any non-cumulative First
Preferred Shares, (ii) in the event that the Bank has a Tier 1 risk-based
capital ratio of less than 4.0% or a total risk-based capital ratio of less than
8.0%, (iii) in the event that the Superintendent takes control of the Bank
pursuant to the Bank Act, or proceedings are commenced for the winding-up of the
Bank pursuant to the Winding-up and Restructuring Act (Canada), or (iv) in the
event that the Superintendent, by order, directs the Bank to act pursuant to
subsection 485(3) of the Bank Act and the Bank elects to cause the exchange.
 
                      BANK ACT RESTRICTIONS AND APPROVALS
 
    Under the Bank Act, the Bank cannot redeem or purchase any of its shares,
including the Series Z Preferred Shares, unless the consent of the
Superintendent has been obtained. In addition, the Bank Act prohibits the
payment to purchase or redeem any shares or the payment of a dividend if there
are reasonable grounds for believing that the Bank is, or the payment would
cause the Bank to be, in contravention of the Bank Act requirement to maintain,
in relation to its operations, adequate capital and appropriate forms of
liquidity and to comply with any regulations or directions of the Superintendent
in relation thereto. Currently these limitations do not restrict the payment of
dividends on or the redemption or purchase of the Series Z Preferred Shares.

                  RESTRAINTS ON BANK SHARES UNDER THE BANK ACT
 
    The Bank Act contains restrictions on the issue, transfer, acquisition,
beneficial ownership and voting of all shares of a bank. By way of summary, no
person is permitted to have a significant interest in any class of shares of a
Schedule I bank, including the Bank. For purposes of the Bank Act, a person has
a significant interest in a class of shares of a bank where the aggregate of any
shares of that class beneficially owned by that person, by entities controlled
by that person and by any person associated or acting jointly or in concert with
that person (as contemplated by the Bank Act) exceeds 10% of all of the
outstanding shares of that class of shares of the Bank.
 
    In addition, these restrictions do not permit Schedule I banks, including
the Bank, to issue or transfer shares of any class to Her Majesty in right of
Canada or of a province, an agent of Her Majesty or a foreign government or any
agent of a foreign government.
 
    Purchasers of the Series Z Preferred Shares may be required to furnish
declarations relative to certain of the foregoing matters in a form prescribed
by the Bank.

    THE BANK ACT
 
    The Bank is a Schedule 1 bank under the Bank Act, and the Bank Act is its

the Bank may engage in and carry on such business generally as appertains to the
business of banking. The Bank Act grants banks broad powers of investment in the
securities of other corporations and entities, but imposes limits upon banks'
substantial investments. A bank has a substantial investment in a body corporate
when (i) the voting shares beneficially owned by the Bank and by entities
controlled by the Bank exceed 10% of the outstanding voting shares of the body
corporate or (ii) the total of the shares of any class of the body corporate
that are beneficially owned by the Bank and entities controlled by the Bank
exceed 25% of the total shareholders' equity of the body corporate. A bank is
entitled to have a substantial investment in a body corporate that is one of the
following, provided that the Bank controls the body corporate and, in certain
cases, the Bank obtains the prior approval of the Minister of Finance of Canada:
a financial institution; a factoring corporation; a financial leasing
corporation; a specialized financing corporation; and a financial holding
corporation, provided that the financial holding corporation does not have a
substantial investment that the Bank may not have. In addition, a bank may have
a substantial investment which can, but need not be, a controlling interest in
the following types of corporations or in any corporation that engages in any
combination of the following: an information services corporation; an investment
counseling and portfolio management corporation; a mutual fund corporation; a
mutual fund distribution corporation; a real property brokerage corporation; a
real property corporation; a service corporation; and a body corporate whose
activities are ancillary to the business of the Bank or of a financial
institution that is a subsidiary of the Bank. Unlike under the former banking
legislation, the investments of Schedule 1 banks in foreign bodies corporate are
now generally subject to the same rules applicable to investments in Canadian
bodies corporate. A bank may not, without the prior approval of the
Superintendent, create a security interest in any of its property to secure an
obligation of the Bank.
 
INSPECTION
 
    The Bank Act also contemplated the appointment of the Superintendent who
administers the Bank Act under the authority granted to him by the Minister of
Finance of Canada. Among other things, the Superintendent is required under the
Bank Act, at least once in each calendar year, to examine and inquire into the
business and affairs of each bank to the extent necessary or expedient to
determine that the
 
                                      A-14
<PAGE>
provisions of the Bank Act are being observed and that each bank is in a sound
financial condition. Reports of these examinations and inquiries are submitted
to the Minister of Finance of Canada. Outside of Canada, a bank's branches,
agencies, subsidiaries and associates are also subject to local regulatory
requirements applicable in the countries in which it conducts business.
 
AUDITORS
 
    Under the Bank Act, the financial statements of the Bank may be audited by
either one or two firms of chartered accountants. During the five fiscal years
ended October 31, 1997, the firm of Raymond, Chabot, Martin, Pare, a general
partnership, served in 1995 and 1996, the firm of Price Waterhouse served in
1993, 1996 and 1997, the firm of Samson Belair/Deloitte & Touche, a general
partnership, served in 1993, 1994 and 1997 and the firm of Mallette Maheu, a
general partnership, served in 1994 and 1995. The auditors are independent of
the Bank as required by all applicable securities legislation of all the
provinces of Canada and the Bank Act. These rules differ from those in the
United States. The firms that served as auditors for the fiscal year ended
October 31, 1997 have informed the Bank that they were independent under U.S.
rules.
 
UNITED STATES
 
    The Bank's only United States branch is located in New York (the "Branch")
and is licensed by the New York Superintendent under the Banking laws of the
State of New York (the "NYBL"). The Branch is examined by the New York State
Banking Department and is subject to banking laws and regulations applicable to
a foreign bank that operates a New York branch. Under the NYBL, the Bank must
maintain with approved banks or trust companies in the State of New York
specified types of interest-bearing governmental obligations, U.S. dollar
deposits, investment grade commercial paper, obligations of certain
international financial institutions and other specified obligations in an
aggregate amount to be determined by the New York Superintendent as security for
the benefit of depositors and other creditors of the Branch. This amount is
currently set at the greater of (i) 5% of the liabilities of the Branch
(excluding liabilities to other offices and certain affiliates of the Bank and
liabilities of the Branch that are booked at its international banking
facility), (ii) 1% of the liabilities of the Branch (excluding liabilities to
other offices and certain affiliates of the Bank) and (iii) $1 million. Under
the NYBL, the New York Superintendent is also empowered to require foreign banks
operating a New York branch to maintain in New York specified assets equal to
such percentage of the branch's liabilities payable at or through the branch as
the New York Superintendent may designate. At present, the New York
Superintendent has set this percentage at 0% for such branches (including the
Branch), although specific asset maintenance requirements may be imposed by the
New York Superintendent on a case-by-case basis.
 
    The banking laws of the State of New York authorize the New York
Superintendent to take possession of the business and property of a New York
branch of a foreign bank under circumstances similar to those which would permit
the New York Superintendent to take possession of the business and property of a
New York state-chartered bank. These circumstances include the violation of any
law, unsafe business procedures, capital impairments, the suspension of payment
of obligations and the initiation of liquidation proceedings against the foreign
bank at its domicile or elsewhere or the existence of reason to doubt the
ability or willingness of such bank to pay in full the claims of holders of
accepted claims specified in the Banking laws of the State of New York. Pursuant
to Section 606.4 of the NYBL, in liquidating or dealing with the branch's
business after taking possession of the branch, only the claims of creditors
which arose out of transactions with the branch are to be accepted by the New
York Superintendent for payment out of the business and property of the foreign
bank in the State of New York.
 
    Under the NYBL, the Branch is generally subject to the same lending limits
to a single borrower, expressed as a ratio of capital, that apply to a New York
state-chartered bank, except that for the Branch such limits are based on the
capital of the Bank.

    Under Section 4(j) of the International Banking Act of 1978 (the "IBA"), if
the Bank were to open a federally licensed branch or agency in the United States
and such federally licensed branch or agency were subsequently to be closed by
the U.S. Comptroller of the Currency, the Comptroller of the Currency could
appoint a receiver for all the property and assets of the Bank in the United
States, including the property and assets of the Branch. In that case, the
liquidation of the Branch's business would be administered by a federal receiver
applying United States federal law, which provides that claims arising out of
transactions with any branch or agency of the Bank located in any State in the
United States shall be paid out of all the properties and assets of the Bank in
the United States.
 
    In addition to being subject to New York State laws and regulations, the
Bank and the Branch are also subject to federal regulation under the IBA and the
Bank is subject to federal regulation under the Bank Holding Company Act of 1956
(the "BHCA"). Under the IBA, United States branches of foreign banks, such as
the Branch, are subject to reserve requirements on deposits held by such
branches and to restrictions on the payment of interest on demand deposits
pursuant to regulations of the Board of Governors of the Federal Reserve System
(the "Board"). Because the Branch engages in a wholesale banking business, its
deposits are not insured by the Federal Deposit Insurance Corporation.
 
    Under the IBA and BHCA, the Bank is subject to certain restrictions with
respect to opening new U.S. domestic deposit-taking branches in states outside
its "home state," which is New York. Recently enacted U.S. Federal law has
generally removed restrictions on acquisitions of banks outside the home state
of the acquiring bank or holding company. These laws and related regulations
also contain certain restrictions on the Bank's ability to engage, directly or
through subsidiaries, in non-banking activities in the United States.
 
    The BHCA also generally prohibits the Bank from, directly or indirectly,
acquiring more than 5% of the voting shares of any company engaged in
non-banking activities in the United States unless the Board has determined, by
order or regulation, that such proposed activities are so closely related to
banking or managing or controlling banks as to be a proper incident thereto. In
addition, the BHCA requires the Bank to obtain the prior approval of the Board
before acquiring, directly or indirectly, the ownership or control of more than
5% of the voting shares of any United States bank or bank holding company.
Federal law also imposes limitations on the ability of the Bank and its
subsidiaries to engage in certain aspects of the securities business in the
United States.
 
    The Foreign Bank Supervision Enhancement Act of 1991 (the "FBSEA"), enacted
December 19, 1991, increased the degree of United States Federal bank regulation
of and supervision over United States branches of foreign banks. The FBSEA
provides, among other things, that the Board may examine such a branch and
provides that each branch of a foreign bank shall be examined at least once
during each 12-month period in an on-site examination. The FBSEA also provides
that the Board may order a foreign bank that operates a state branch to
terminate the activities of such branch if the Board finds that the foreign bank
is not subject to comprehensive supervision or regulation on a consolidated
basis by the appropriate authorities in its home country, or that there is
reasonable cause to believe that such foreign bank, or any affiliate of such
foreign bank, has committed a violation of law or engaged in an unsafe or
unsound banking practice in the United States, and, as a result of such
violation or practice, the continued operation of the branch would not be
consistent with the public interest or with the IBA, the BHCA or the Federal
Deposit Insurance Act. A foreign bank so required to terminate activities
conducted at a branch in the United States must comply with the requirements of
applicable United States Federal and state law with respect to procedures for
the closure or dissolution thereof. The FBSEA also provides that a state branch
of a foreign bank may not engage in any type of activity that is not permissible
for a United States Federal branch of a foreign bank unless the Board has
determined that such activity is consistent with sound banking practice.

                         THE CANADIAN BANKING INDUSTRY
 
    Canadian banks are a vital force in Canada's economy, facilitating the flow
of a large part of the nation's savings into various productive uses. As at
September 30, 1997, there were 53 banks in Canada, of which eleven were domestic
banks and 42 were Canadian subsidiaries of foreign-owned banks. The Banks as a
group are the largest financial intermediaries in Canada. As at September 30,
1997, Canadian banks had total assets of some $1,205 billion, of which the
largest six banks, including the Bank, accounted for over 91%. Other important
financial institutions include investment dealers, property and casualty
insurance companies, life insurance companies, trust companies, pension funds
and credit unions.
 
                                 ASSET COVERAGE
 
    As at October 31, 1997, after giving effect to the automatic exchange and
taking into account the items mentioned below, the adjusted net tangible assets
of the Bank available to cover all the outstanding First Preferred Shares and
debentures were as follows:

</TABLE>
 
    The adjusted net tangible assets available for the outstanding First
Preferred Shares of the Bank amounted to approximately 3.1 times the aggregate
issue price for the outstanding First Preferred Shares (including the proceeds
of the automatic exchange in the case of the Series Z Preferred Shares). The
adjusted net tangible assets (before deduction of debentures) amounted to 1.9
times the sum of the principal amount of such debentures and the aggregate issue
price of the First Preferred Shares.
 
                         DIVIDEND AND INTEREST COVERAGE
 
    Based on an annual dividend rate on the Series Z Preferred Shares of 8.45%
and assuming an average prime rate of 5.75%, the annual dividend requirement of
the Series Z Preferred Shares, of the First Preferred Shares Series 5 (286,610
shares), Series 7 (422,633 shares), Series 8 (789,638 shares), Series 10
(3,680,000 shares), Series 11 (4,000,000 shares) and Series 12 (5,000,000
shares) outstanding of the Bank (collectively, the "First Preferred Shares"),
would amount to $62.3 million. The Bank's net income, after income taxes and
non-controlling interest, for the twelve months ended October 31, 1997 was $342
million. This amount is 5.5 times such annual dividend requirement.
 
    The annual interest requirement on all debentures of the Bank outstanding as
at October 31, 1997 amounts to $76.5 million, assuming a six month London
interbank offered rate (LIBOR, of 5.8125% on floating rate debentures and
assuming the following exchange rates: Cdn. $1.4084 per US$1.00; Cdn. $0.0117
per (Y) 1; Cdn. $2.3570 per (pound) 1.00; and Cdn. $1.0134 per AUD$1.00, being
the closing rates of the Bank of Canada at October 31, 1997.
 
                                      A-17
<PAGE>
    The Bank's net income, before income taxes and non-controlling interest and
before deduction of interest on outstanding debentures for the twelve months
ended October 31, 1997, amounted to $680 million. This amount is 8.9 times the
total amount of $76.5 million required for total payment of interest on
outstanding debentures.
 
    Taking into account the items described above, the annual dividend
requirement for the First Preferred Shares would amount to $103.8 million
grossed up on a pre-tax equivalent basis assuming an effective marginal tax rate
of 40%. The Bank's net income before income taxes and non-controlling interest
and before deduction of interest on the outstanding debentures, for the twelve
months ended October 31, 1997 of $680 million, is equal to 3.8 times the
aggregate interest on the outstanding debentures and grossed-up dividend
requirements totalling $180.3 million.
 
                       CHANGES IN SHARE AND LOAN CAPITAL
 
    Since October 31, 1997, the only material changes in the share and loan
capital of the Bank have been the issue of 78,513 Common Shares for a
consideration of $1,562,515 under the Bank's Dividend Reinvestment and Share
Purchase Plan.
 
                                     RATING
 
    The outstanding non-cumulative First Preferred Shares of the Bank are rated
P-3 (high) by Canadian Bond Rating Service Inc. ("CBRS"), the third highest of
the five categories used by CBRS.
 
    The outstanding non-cumulative First Preferred Shares of the Bank are rated
Pfd-2 (low) by Dominion Bond Rating Service Limited ("DBRS"), the second highest
of five categories of rating used by DBRS for preferred shares. In certain
cases, preferred shares may have a "low" characterization to reflect an issuer's
relative strength within a rating category.
 
    Neither of the foregoing ratings should be construed as a recommendation to
buy, sell or hold securities, including the Series Z Preferred Shares. The
foregoing ratings are effective as of the date of this short form prospectus.
Either of the foregoing ratings may be revised or withdrawn at any time by the
respective rating organization and, as a consequence, may not be the same if and
when an automatic exchange for the Series Z Preferred Shares takes place, as
contemplated under "Automatic Exchange" in this short form prospectus.
 
                                 LEGAL MATTERS
 
    The legality of the securities offered by this short form prospectus has
been passed upon for the Bank by Desjardins Ducharme Stein Monast, a general

       (LIQUIDATION PREFERENCE EQUIVALENT TO US$25 PER DEPOSITARY SHARE)
            EACH REPRESENTING A ONE-FORTIETH INTEREST IN A SHARE OF
   8.35% NONCUMULATIVE EXCHANGEABLE PREFERRED STOCK, SERIES A, OF NB CAPITAL
                                  CORPORATION
                  (LIQUIDATION PREFERENCE US$1,000 PER SHARE)
         EXCHANGEABLE INTO PREFERRED SHARES OF NATIONAL BANK OF CANADA
    
                            ------------------------
 
   
    This Prospectus relates to the offer (the "Offering") of Depositary Shares,
each representing a one-fortieth interest in a share of 8.35% Noncumulative
Exchangeable Preferred Stock, Series A, par value US$.01 per share (the "Series
A Preferred Shares"), of NB Capital Corporation (the "Company"), a wholly owned
subsidiary of National Bank of Canada (the "Bank") or, as discussed below, upon
the occurrence of an event that results in an automatic exchange (an "Exchange
Event") of Series A Preferred Shares for the Bank's 8.45% Noncumulative First
Preferred Shares, Series Z (the "Bank Preferred Shares"), a one-fortieth
interest in a Bank Preferred Share.
    
 
    The Company's principal business objective is to acquire, hold, finance and
manage assets consisting of obligations secured by real property, as well as
certain other qualifying real estate investment trust ("REIT") assets ("Mortgage
Assets"). The Mortgage Assets currently consist of (i) sixteen "hypothecation
loans" (the "Initial Mortgage Assets") issued to the Company by NB Finance,
Ltd., a wholly owned subsidiary of the Bank ("NB Finance"), that are recourse
only to the "Initial Mortgage Loans" and (ii) cash. Hypothecation loans are
loans secured by the pledge of mortgages as security therefor. The Initial
Mortgage Loans consist of sixteen pools of, at December 31, 1997, 11,692
"Mortgage Loans." Mortgage Loans consist of residential first mortgages insured
by Canada Mortgage and Housing Corporation, an agency of the Government of
Canada ("CMHC"), that are secured by real property located in Canada.
 
    SEE "RISK FACTORS" COMMENCING ON PAGE 16 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY POTENTIAL HOLDERS OF DEPOSITARY SHARES, INCLUDING
THE FOLLOWING:
 
   
    - The Company's income consists principally of payments of interest and,
      therefore, is heavily dependent upon prevailing interest rates.
      Additionally, the Company's income is dependent upon Canadian dollar
      denominated assets. Consequently, a significant decline in interest rates
      or in the value of the Canadian dollar may have an adverse effect on the
      Company, its assets and its ability to make dividend payments with respect
      to the Series A Preferred Shares and, accordingly, the Depositary Shares.
    
 
    - The Company's operations may be affected by prevailing real estate market
      conditions. Consequently, there can be no assurance that prevailing real
      estate market conditions will not adversely affect the Company's ability
      to pay dividends.
 
   
    - All of the residential real properties securing the Initial Mortgage
      Assets issued by NB Finance are, and in the future any real properties
      securing the Mortgage Assets are expected to be, located outside the
      United States, primarily Quebec, Ontario and New Brunswick. Consequently,
      the Company will be subject to the laws of a foreign jurisdiction with
      respect to any actions taken in respect of such real properties and its
      assets may be subject to a greater risk of default than investments in
      comparable U.S. real property.
    
 
   
    - The Initial Mortgage Assets issued by NB Finance are recourse only to the
      Initial Mortgage Loans. Consequently, in the event of default on the
      Initial Mortgage Assets issued by NB Finance, the Company's principal
      recourse will be foreclosure on the real property securing the Initial
      Mortgage Assets issued by NB Finance and, in certain circumstances, CMHC
      insurance may not be available or receipt of payment thereof may be
      delayed.
    
 
    - Dividends on the Series A Preferred Shares are not cumulative.
      Consequently, if the Board of Directors of the Company (the "Board of
      Directors") does not authorize and declare a dividend on the Series A
      Preferred Shares for any particular quarterly dividend period, the holders
      of the Series A Preferred Shares and, accordingly, the Depositary Shares
      would not be entitled to recover such dividend even if funds are, or
      subsequently become, available for payment thereof.
 
   
    - As a subsidiary of the Bank, Canadian banking authorities could, under
      certain circumstances, impose certain restrictions on the operations of
      the Company. Consequently, such restrictions could cause the Company to
      fail to qualify as a REIT as well as affect its ability to pay dividends.
    
 
   
    - The Company may not qualify as a REIT for United States federal income tax
      purposes. Consequently, the Company could be subject to United States
      federal income tax at normal corporate tax rates.
    
 
    - The Board of Directors may amend or revise the Company's policies and
      strategies in the future without a vote of stockholders, including holders
      of the Series A Preferred Shares and holders of Depositary Shares.
      Consequently, the holders of Series A Preferred Shares or Depositary
      Shares cannot preclude the Board of Directors from making such amendments
      or revisions even though the ultimate effect on the holders of Series A
      Preferred Shares and holders of Depositary Shares may be negative.

THE SECURITIES DESCRIBED HEREIN HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
    SECURITIES AND EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON
       THE ACCURACY OR DETERMINED THE ADEQUACY OF THIS PROSPECTUS. ANY
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
                           --------------------------
 
   
                 The date of this Prospectus is April   , 1998.

                                [ALTERNATE PAGE]
(COVER CONTINUED)
 
   
    - The assets of the Company consist of obligations that do not provide for
      complete amortization of principal over their term to maturity and,
      therefore, require a balloon payment. Consequently, holders of Series A
      Preferred Shares and, accordingly, holders of Depositary Shares may be
      accepting a greater degree of risk relative to an investment with
      underlying assets that are comprised of fully amortizing obligations.
    
 
    - The Company has not obtained a third party valuation of its assets for the
      purposes of the Offering. Consequently, there can be no assurance that the
      fair market value of such assets does not differ from the purchase price
      thereof.
 
   
    - Under certain circumstances, including when the Bank is experiencing
      financial difficulties or its financial condition is deteriorating, the
      Series A Preferred Shares could be exchanged automatically for the Bank
      Preferred Shares (i.e., an Exchange Event). Immediately upon the
      occurrence of an Exchange Event, each Depositary Share will represent a
      one-fortieth interest in a Bank Preferred Share and will no longer
      represent a fractional interest in a Series A Preferred Share.
      Consequently, the Depositary Shares could represent an investment in the
      Bank and not in the Company at a time when the Bank is experiencing such
      financial difficulties or such deterioration of financial condition.
    
 
    - The Company is dependent upon the Bank and its affiliates in virtually
      every phase of its operations. However, the interests of the Company and
      the Bank may not be identical. Consequently, because of the relationship
      between the Company and the Bank and its affiliates, conflicts of interest
      may arise between the Company and the Bank.
 
    - The assignment of the Initial Mortgage Loans to the Company has not been
      registered. Consequently, a bona fide purchaser who completes all
      necessary registration formalities prior to the Company would be
      recognized as the owner of the Initial Mortgage Loans.
 
    - The Company intends to list the Depositary Shares on the New York Stock
      Exchange (the "NYSE"). The Company is under no obligation, and currently
      has no intention, to list the Series A Preferred Shares on a national
      exchange. Additionally, there is no existing market for the Series A
      Preferred Shares and there can be no assurance as to the liquidity of any
      markets that may develop, the ability of holders to sell their Series A
      Preferred Shares or the sale price thereof. Consequently, holders of
      Series A Preferred Shares may find it difficult to sell their Series A
      Preferred Shares or to sell their Series A Preferred Shares at a price
      equivalent to the purchase price thereof.
 
    The Company has indicated that it will update the information included in
this Prospectus for a period of six-months from the date hereof. Accordingly,
there can be no guarantee that the Depositary will accept surrenders of Series A
Preferred Shares at anytime thereafter. The Series A Preferred Shares and,
accordingly, the Depositary Shares represent an obligation of the Company and do
not represent an obligation of NB Finance, or prior to an Exchange Event, the
Bank.
 
 CERTAIN PERSONS PARTICIPATING IN THE OFFERING MAY ENGAGE IN TRANSACTIONS THAT
 STABILIZE, MAINTAIN, OR OTHERWISE AFFECT THE PRICE OF THE PREFERRED SHARES OR
     THE DEPOSITARY SHARES. SUCH TRANSACTIONS MAY INCLUDE STABILIZING, THE
      PURCHASE OF THE PREFERRED SHARES OR THE DEPOSITARY SHARES TO COVER
         SYNDICATE SHORT POSITIONS AND THE IMPOSITION OF PENALTY BIDS.

                                  THE COMPANY
 
    GENERAL
 
    The Company is a Maryland corporation incorporated on August 20, 1997. The
Bank was the organizer of the Company. All of the common stock, par value $.01
per share, of the Company (the "Common Stock") is owned by National Bank of
Canada (the "Bank"). The Company's principal business objective is to acquire,
hold, finance and manage assets consisting of obligations secured by real
property, as well as certain other qualifying REIT assets ("Mortgage Assets").
The Company will elect to be taxable as a REIT under the Internal Revenue Code
of 1986, as amended (the "Code"), and generally will not be liable for United
States federal income tax to the extent that it distributes its income to its
stockholders and maintains its qualification as a REIT. See "United States
Federal Income Tax Considerations-- Qualification of the Company as a REIT." The
Bank has indicated to the Company that, for as long as any of the Series A
Preferred Shares are outstanding, the Bank intends to continue to own all of the
outstanding shares of the Common Stock. The Company was formed to provide
investors with the opportunity to invest in Canadian residential mortgages and
other real estate assets and to provide the Bank with a cost-effective means of
raising capital. The Company began operations on September 3, 1997.
 
    The Company's charter (the "Charter") and bylaws (the "Bylaws") both become
operational on August 20, 1997. Pursuant to the Charter, the duration of the
Company is perpetual, except that effective as of the close of business on the
date the Company delivers a notice of an Exchange Event, without the need for
any approval by the Board of Directors or the stockholders of the Company, the
existence of the Company will terminate and the Company will be liquidated and
its affairs wound up in accordance with Maryland law.
 
MORTGAGE ASSETS
 
   
    The Company's Mortgage Assets currently consist of (i) sixteen hypothecation
loans (the "Initial Mortgage Assets"), in an aggregate amount at December 31,
1997 of US$457 million, issued to the Company by NB Finance that are recourse
only to the "Initial Mortgage Loans" and (ii) cash. The Initial Mortgage Loans
consist of sixteen pools of, at December 31, 1997, 11,692 "Mortgage Loans" in an
aggregate amount at December 31, 1997 of C$793 million (US$554 million).
Accordingly, the Initial Mortgage Assets issued by NB Finance are
over-collateralized by US$97 million. Mortgage Loans consist of CMHC-insured
residential first mortgages that are secured by real property located in Canada.
The Initial Mortgage Assets issued by NB Finance will mature semiannually
beginning in 2000 and the proceeds thereof (net of distributions and expenses)
are expected to be reinvested in additional Mortgage Assets as described under
"Business and Strategy--Description of Mortgage Assets; Investment Policy."
    
 
    The Company acquired the Initial Mortgage Assets (which are U.S. dollar
denominated) backed by the Initial Mortgage Loans (which are Canadian dollar
denominated), rather than purchasing the Initial
 
                                       1
<PAGE>
Mortgage Loans directly, in order to eliminate potential foreign exchange gain
or loss and to provide a U.S. dollar denominated income stream that matched its
obligations on the Preferred Stock.
 
SERIES A PREFERRED SHARES
 
   
    On September 3, 1997 (the "Issue Date"), 300,000 Series A Preferred Shares
were issued and sold to Merrill Lynch, Pierce, Fenner & Smith Incorporated (the
"Initial Purchaser") in a transaction not registered under the Securities Act of
1933, as amended (the "Securities Act") in reliance upon an exemption from the
registration requirements thereof. The Initial Purchaser simultaneously sold
238,400 Series A Preferred Shares in transactions exempt from the registration
requirements of the Securities Act in the United States to persons reasonably
believed by the Initial Purchaser to be "qualified institutional buyers" (as
defined in Rule 144A under the Securities Act), to institutional "accredited
investors" (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities
Act) and outside the United States to non-United States persons in offshore
transactions in reliance on Regulation S under the Securities Act. As of April
22, 1998, the holders of Series A Preferred Shares other than the Initial
Purchaser held of record 238,400 Series A Preferred Shares, or approximately
79.5% of the outstanding Series A Preferred Shares, that may be deposited with
The Bank of Nova Scotia Trust Company of New York (the "Depositary") against
receipt of Depositary Receipts evidencing up to 9,536,000 Depositary Shares.
    
 
    The principal executive offices of the Company are located at 125 West 55th
Street, New York, New York 10019. The telephone number of the Company is (212)
632-8500.
 
                                    THE BANK
 
    GENERAL
 
    The Bank was formed through a series of amalgamations and its roots date
back to 1859 with the founding of the Banque Nationale in Quebec City. Its head
office and principal place of business is located at the National Bank Tower,
600 de La Gauchetiere West, Montreal, Quebec, H3B 4L2, and its telephone number
is (514) 394-5000.
 
    The Bank is a Schedule I bank under the Consolidated Bank Act (Canada), as
amended (the "Bank Act"). The Bank Act is the charter governing all banks in
Canada (both domestic banks and branches of foreign banks operating in Canada).
"Schedule I" of the Bank Act lists all Canadian domestic banks. "Schedule II" of
the Bank Act lists all subsidiaries of foreign banks with branches in Canada.
The specific provisions of the Bank Act that govern a particular bank depend
upon the schedule on which such bank is listed. As a Canadian domestic bank, the
Bank is a "Schedule I Bank."
 
    The Bank, which ranks sixth among Canadian banks in terms of total assets,
is present in each of Canada's provinces. It delivers an extensive range of
financial services to individuals, commercial enterprises, financial
institutions and governments both in Canada and abroad.
 
    Additional information regarding the Bank is included in the Bank's
short-form prospectus related to the Bank Preferred Shares affixed to this
Prospectus as Annex A.
 
PREFERRED SHARES OF THE BANK
 
    The authorized preferred capital of the Bank consists of an unlimited number
of First Preferred Shares ("First Preferred Shares") and up to 15 million Second
Preferred Shares which may be issued for a maximum aggregate consideration of
C$1 billion and C$300 million, respectively, or the equivalent thereof in other
currencies. The Board of Directors of the Bank may by resolution establish the
terms of series of preferred shares. The Bank currently has six series of First
Preferred Shares outstanding with an aggregate liquidation preference as of
October 31, 1997 of C$376 million.

                                    preference (an amount equal to US$83.50 per annum per
                                    share calculated by multiplying the annual dividend rate
                                    of 8.35% by the liquidation preference of US$1,000 per
                                    share, assuming authorization and declaration by the
                                    Board of Directors of four quarterly dividends), if,
                                    when and as authorized and declared by the Board of

                                    June, September and December in each year, commencing
                                    December 30, 1997. Dividends accrue in each quarterly
                                    period from the first day of such period, whether or not
                                    dividends were paid with respect to the preceding
                                    period. Dividends on the Series A Preferred Shares are
                                    not cumulative and, accordingly, if no dividend is
                                    authorized and declared on the Series A Preferred Shares

GENERAL
 
    Each Depositary Share represents a one-fortieth interest in a Series A
Preferred Share. The Series A Preferred Shares underlying the Depositary Shares
will be deposited with The Bank of Nova Scotia Trust Company of New York, as
Depositary (the "Depositary"), under a Deposit Agreement (the "Deposit
Agreement"), among the Company, the Bank, the Depositary and all holders, from
time to time, of depositary receipts issued by the Depositary thereunder (the
"Depositary Receipts"). The Company intends to list the Depositary Shares, and
expects that the Depositary Shares will be approved for listing, on the NYSE.
The Company does not plan to list the Series A Preferred Shares on any national
exchange. Accordingly, the Company does not expect that there will be any public
trading market for the Series A Preferred Shares except as represented by the
Depositary Shares. The Depositary Shares will be evidenced by Depositary
Receipts.
 
    The Company has indicated that it will update the information included in
this Prospectus for a period of six months from the date hereof. Accordingly,
there is no guarantee that the Depositary will accept surrenders of Series A
Preferred Shares at any time thereafter.
 
    Subject to the terms of the Deposit Agreement, each owner of a Depositary
Share will be entitled through the Depositary, in proportion to the one-fortieth
interest in a Series A Preferred Share underlying such Depositary Share, to all
the rights, preferences and privileges of a Series A Preferred Share (including
dividend, voting, redemption and liquidation rights), and will be subject to all
of the limitations of the fractional share of Series A Preferred Shares
represented thereby. See "Description of Series A Preferred Shares." Since each
Series A Preferred Share entitles the holder thereof to one vote on matters on
which the Series A Preferred Shares are entitled to vote, each Depositary Share
will, in effect, entitle the holder thereof to one-fortieth of a vote thereon,
rather than one full vote. See "Description of Series A Preferred Shares--Voting
Rights."
 
    The Depositary will act as transfer agent and registrar and paying agent
with respect to the Depositary Shares.
 
    After the date fixed for redemption (which will be the same date as any
redemption date for the Series A Preferred Shares), the Depositary Shares so
called for redemption will no longer be deemed to be outstanding and all rights
of the holders of the Depositary Shares will cease, except the right to receive
the moneys payable upon such redemption and any money or other property to which
the holders of such Depositary Shares were entitled upon such redemption upon
surrender to the Depositary of the Depositary Receipts evidencing such
Depositary Shares.
 
VOTING RIGHTS
 
    Upon receipt of notice of any meeting at which the holders of the Series A
Preferred Shares are entitled to vote, the Depositary will mail the information
contained in such notice of meeting to the record holders of the Depositary
Shares representing the Series A Preferred Shares. Each record holder of such
Depositary Shares on the record date (which will be the same date as the record
date for the Series A Preferred Shares) will be entitled to instruct the
Depositary as to the exercise of the voting rights pertaining to the number of
whole Series A Preferred Shares underlying such holder's Depositary Shares. The
Depositary will endeavor, insofar as practicable, to vote the number of whole
Series A Preferred Shares underlying such Depositary Shares in accordance with
such instructions, and the Company and the Bank will agree to take all action
that may be deemed necessary by the Depositary in order to enable the Depositary
to do so. The Depositary will abstain from voting the Series A Preferred Shares
to the extent the Depositary does not receive specific instructions from the
holders of Depositary Shares relating to such shares.

UNRELATED BUSINESS TAXABLE INCOME
 
   
    Plan fiduciaries should also consider the consequences of holding more than
10% of the Series A Preferred Shares or Depositary Shares representing more than
10% of the Series A Preferred Shares if the Company is "predominantly held" by
qualified trusts. See "United States Federal Income Tax Considerations Treatment
of Tax-Exempt Entities."
    
 
                                    RATINGS
 
    The Series A Preferred Shares are rated "a2" by Moody's Investors Service,
Inc. and "BBB+" by Standard & Poor's Ratings Services. A security rating is not
a recommendation to buy, sell or hold securities and may be subject to revision
or withdrawal at any time by the assigning rating organization. No person is
obligated to maintain any rating on the Series A Preferred Shares, and,
accordingly, there can be no assurance that the ratings assigned to the Series A
Preferred Shares will not be lowered or withdrawn by the assigning rating
organization at any time thereafter.
 
                              PLAN OF DISTRIBUTION
 
   
    Depositary Receipts evidencing Depositary Shares will be issued by the
Depositary upon surrender thereto of Series A Preferred Shares by the holders of
Series A Preferred Shares other than the Initial Purchaser. The Company has
indicated that it will update the information included in this Prospectus for a
period of six-months from the date hereof. Accordingly, there is no guarantee
that the Depositary will accept surrenders of Series A Preferred Shares at any
time thereafter. The Depositary Shares may be sold from time to time to
purchasers directly by the holders thereof.
    
 
   
    Depositary Shares are to be offered on the basis of forty Depositary Shares
for each Series A Preferred Share deposited with the Depositary. The Depositary
will be paid customary fees and will be reimbursed for out-of-pocket expenses.
Pursuant to the Deposit Agreement, holders of Series A Preferred Shares who
deposit their Series A Preferred Shares against receipt of Depositary Shares
will not bear the fees and expenses of the Depositary in connection with such
deposit of Series A Preferred Shares and receipt of Depositary Shares. Other
than any liability or expense arising out of negligence or bad faith (a) the
Depositary will be indemnified against any liability or expense arising out of
acts performed or omitted under the Deposit Agreement and (b) the Company and
the Bank will be indemnified against any liability or expense arising out of
acts performed or omitted by the Depositary, or any agent thereof, under the
Deposit Agreement.
    
 
   
    This Prospectus, as it may be amended or supplemented from time to time, may
be used by a broker-dealer in connection with resales of Series A Preferred
Shares received pursuant to the Exchange Offer in exchange for Series A
Preferred Shares then outstanding ("Old Preferred Shares") where such Old
Preferred Shares were acquired as a result of market-making activities or other
trading activities as well as Depositary Shares representing such Series A
Preferred Shares. To the extent any such broker-dealer participated in the
Exchange Offer, the Company has agreed that, for a period of up to six months
after the date of this Prospectus, it will make this Prospectus, as amended or
supplemented, available to such broker-dealer for use in connection with any
such resale of Series A Preferred Shares and, accordingly, Depositary Shares
representing such Series A Preferred Shares, will update this Prospectus, as
required, during such six-month period and will promptly send additional copies
of this Prospectus and any amendment or supplement to this Prospectus to any
broker-dealer that requests such documents.
    
 
    The Company intends to list the Depositary Shares on the NYSE.

ITEM 33. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    INDEMNIFICATION UNDER MARYLAND LAW AND UNDER THE COMPANY'S CHARTER AND
     BYLAWS
 
    The Maryland General Corporation Law ("MGCL") permits a Maryland corporation
to include in its charter a provision limiting the liability of the
corporation's directors and officers to the corporation and its stockholders for
money damages except for liability resulting from (a) actual receipt of an
improper benefit or profit in money, property or services or (b) active and
deliberate dishonesty established by a final judgment as being material to the
cause of action. The Charter contains such a provision which eliminates such
liability to the maximum extent permitted by the MGCL.
 
    The Charter authorizes the Company, to the maximum extent permitted by
Maryland law, to obligate itself to indemnify and to pay or reimburse reasonable
expenses in advance of final disposition of a proceeding to (a) any present or
former director or officer or (b) any individual who, while a director of the
Company and at the request of the Company, serves or has served another
corporation, partnership, joint venture, trust, employee benefit plan or any
other enterprise as a director, officer, partner or trustee of such corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
from and against any claim or liability to which such person may become subject
or which such person may incur by reason of his or her status as a present or
former director or officer of the Company. The Bylaws of the Company (the
"Bylaws") obligate it, to the maximum extent permitted by Maryland law, to
indemnify and to pay or reimburse reasonable expenses in advance of final
disposition of a proceeding to (a) any present or former director or officer who
is made a party to the proceeding by reason of his service in that capacity or
(b) any individual who, while a director of the Company and at the request of
the Company, serves or has served another corporation, partnership, joint
venture, trust, employee benefit plan or any other enterprise as a director,
officer, partner or trustee of such corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise and who is made a party to the
proceeding by reason of his service in that capacity. The Charter and Bylaws
also permit the Company to indemnify and advance expenses to any person who
served a predecessor of the Company in any of the capacities described above and
to any employee or agent of the Company or a predecessor of the Company.
 
    The MGCL requires a corporation (unless its charter provides otherwise,
which the Charter does not) to indemnify a director or officer who has been
successful, on the merits or otherwise, in the defense of any proceeding to
which he is made a party by reason of his service in that capacity. The MGCL
permits a corporation to indemnify its present and former directors and
officers, among others, against judgments, penalties, fines, settlements and
reasonable expenses actually incurred by them in connection with any
 
                                      II-1
<PAGE>
proceeding to which they may be made a party by reason of their service in those
or other capacities unless it is established that (a) the act or omission of the
director or officer was material to the matter giving rise to the proceeding and
(i) was committed in bad faith or (ii) was the result of active and deliberate
dishonesty, (b) the director or officer actually received an improper personal
benefit in money, property or services or (c) in the case of any criminal
proceeding, the director or officer had reasonable cause to believe that the act
or omission was unlawful. However, under the MGCL, a Maryland corporation may
not indemnify for an adverse judgment in a suit by or in the right of the
corporation or for a judgment of liability on the basis that personal benefit
was improperly received, unless in either case a court orders indemnification
and then only for expenses. In addition, the MGCL requires the Company, as a
condition to advancing expenses, to obtain (a) a written affirmation by the
director or officer of his good faith belief that he has met the standard of
conduct necessary for indemnification by the Company and (b) a written statement
by or on his behalf to repay the amount paid or reimbursed by the Company if it
shall ultimately be determined that the standard of conduct was not met.

ITEM 36. UNDERTAKINGS
 
    The undersigned hereby undertakes:
 
    (a) The undersigned registrant hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:
 
            (i) To include any prospectus required by section 10(a)(3) of the
       Securities Act of 1933;
 
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. Notwithstanding the foregoing, any increase
       or decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the low or high end of the estimated maximum offering
       range may be reflected in the form of prospectus filed with the
       Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
       volume and price represent no more than a 20% change in the maximum
       aggregate offering price set forth in the "Calculation of Registration
       Fee" table in the effective registration statement.
 
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.
 
    PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section
do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3,
and the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to section 13 or section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.
 
                                      II-3
<PAGE>
        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
        (4) If the registrant is a foreign private issuer, to file a
    post-effective amendment to the registration statement to include any
    financial statements required by Section 210.3-19 of this chapter at the
    start of any delayed offering or throughout a continuous offering. Financial
    statements and information otherwise required by Section 10(a)(3) of the Act
    need not be furnished, provided that the registrant includes in the
    prospectus, by means of a post-effective amendment, financial statements
    required pursuant to this paragraph (a)(4) and other information necessary
    to ensure that all other information in the prospectus is at least as
    current as the date of those financial statements. Notwithstanding the
    foregoing, with respect to registration statements on Form F-3, a
    post-effective amendment need not be filed to include financial statements
    and information required by Section 10(a)(3) of the Act or Section 210.3-19
    of this chapter if such financial statements and information are contained
    in periodic reports filed with or furnished to the Commission by the
    registrant pursuant to section 13 or section 15(d) of the Securities
    Exchange Act of 1934 that are incorporated by reference in the Form F-3.
 
    (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
    (c) The undersigned registrant hereby undertakes to provide to the
underwriter at the closing specified in the underwriting agreements certificates
in such denominations and registered in such names as required by the
underwriter to permit prompt delivery to each purchaser.
 
    (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
    (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

NB Capital Corporation
125 West 55th Street
New York, NY  10019



                          Issuance by NB Capital Corporation
                      of up to Twelve Million Depositary Shares
                      -----------------------------------------


Ladies and Gentlemen:

     We have acted as counsel for NB Capital Corporation, a Maryland 
corporation (the "Company"), in connection with the Registration Statement on 
Form S-11 (the "Registration Statement") filed by the Company with the 
Securities and Exchange Commission on April 1, 1998, and amended on the date 
hereof, under the Securities Act of 1933, as amended (the "Act"), with 
respect to up to twelve million depositary shares (the "Depositary Shares"), 
each representing a one-fortieth interest in a share of 8.35% Noncumulative 
Exchangeable Preferred Stock, Series A (the "Series A Preferred Shares"), of 
the Company.  The Depositary Shares are described in the prospectus (the 
"Prospectus") included in the Registration Statement to which this opinion is 
an exhibit.

     In that connection, we have examined the Registration Statement and
originals, or copies certified or otherwise identified to our satisfaction, of
such other documents, corporate records, certificates and other instruments as
we have deemed necessary or appropriate for purposes of this opinion.  In such
examination, we have assumed the genuineness of all signatures, the authenticity
of all documents, certificates, and instruments submitted to us as originals and
the conformity with the originals of all documents submitted to us as copies.

     Based upon the foregoing, we are of the opinion that when (a) the
registration requirements of the Act and such state blue sky or securities laws
as may be applicable have been complied with, (b) the Depositary Shares have
been duly issued and sold in the 

<PAGE>

                                          2



manner contemplated by the Registration Statement and (c) The Bank of Nova 
Scotia Trust Company of New York (the "Depositary") has duly executed the 
receipts evidencing the Depositary Shares in accordance with the terms of the 
Deposit Agreement between the Company, National Bank of Canada, the direct 
parent of the Company, and the Depositary (the holders of the Series A 
Preferred Shares having deposited the Series A Preferred Shares with the 
Depositary pursuant to the Deposit Agreement), such Depositary Shares will 
represent legal and valid interests in the Series A Preferred Shares.

     Our opinion expressed herein is limited to the law of the Sate of New York
and the Federal law of the United States, and we do not express any opinion
herein concerning any other law.

     We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and the reference to us under the heading "Legal 
Matters" contained in the Prospectus.

                                        Very truly yours,

                                        /s/ Sherman & Sterling
