                                  THE COMPANY
 
  MBIA Inc. (the "Company") insures municipal bonds, asset-backed securities
and other non-municipal bonds through its wholly-owned subsidiary, MBIA
Insurance Corporation ("MBIA Corp."). MBIA Corp.'s primary business is
enhancing the efficiency of public finance by guaranteeing the timely payment
of principal and interest on municipal bonds sold in the new issue market,
traded in the secondary market and held in unit investment trusts and mutual
funds. MBIA Corp. is the market leader with over 40% market share of the
insured new issue municipal business. MBIA Corp. also provides financial
guarantees for structured finance transactions (principally mortgage-backed
and asset-backed securities), investor-owned utility debt and obligations of
high-quality financial institutions. For the nine months ended September 30,
1995, MBIA Corp. insured $23.4 billion par value of new issue and secondary
market municipal bonds and $6.8 billion par value of domestic structured
finance business. As of September 30, 1995, the total net par amount of
outstanding bonds insured by MBIA Corp. was $181.5 billion and the aggregate
net insurance in force was $332.7 billion.
 
  Financial guarantee insurance provides an unconditional and irrevocable
guarantee of the payment of the principal of and interest on insured
obligations when due. MBIA Corp. primarily insures obligations sold in the new
issue and secondary markets, including those held in unit investment trusts
and by mutual funds. It also provides surety bonds for debt service reserve
funds. The principal economic value of financial guarantee insurance to the
entity offering the obligations is the saving in interest costs resulting from
the difference in the market yield between an insured obligation and the same
obligation on an uninsured basis. In addition, for complex financings and for
obligations of issuers that are not well known by investors, insured
obligations receive greater market acceptance than uninsured obligations. All
obligations insured by MBIA Corp. are rated AAA by both Standard & Poor's
Ratings Group, a division of The McGraw-Hill Companies, Inc. and Fitch
Investors Service, L.P. and Aaa by Moody's Investors Service, Inc., the
highest ratings assigned by these rating agencies.
 
  The Company's insurance subsidiaries derive their income from insurance
premiums earned over the life of the insured obligations and from investment
income earned on assets representing capital, retained earnings, and deferred
premium revenues. As of September 30, 1995, the Company's deferred premium
revenues were $1,599 million, its shareholders' equity was $2,090 million, and
its total investments were $5,946 million and $6,138 million at book value and
market value, respectively. As of September 30, 1995, MBIA Corp.'s investment
portfolio was $3,520 million and $3,668 million at book value and market
value, respectively, and was primarily comprised of high quality fixed income
securities with intermediate maturities.
 
  In 1990, the Company formed a French company, MBIA Assurance S.A. ("MBIA
Assurance"), to assist in writing financial guarantee insurance in the
countries of the European Community. MBIA Assurance, which is a subsidiary of
MBIA Corp., writes policies insuring public infrastructure financings, asset-
backed transactions and certain obligations of financial institutions. As of
September 30, 1995, MBIA Corp. and MBIA Assurance had collectively insured 50
international transactions. In September 1995, MBIA Corp. entered into a joint
venture agreement with AMBAC Indemnity Corporation for the purpose of jointly
marketing financial guarantee insurance within the European Community.
 
  Over the last three years, the Company has undertaken the development of
investment management services which capitalize on its capabilities,
reputation and marketplace relationships. The Company is delivering these
services through a group of subsidiary companies. For the nine months ended
September 30, 1995, in the aggregate, these investment management ventures
contributed $10 million to revenues.
 
  The financial guarantee industry is subject to the direct and indirect
effects of governmental regulation, including changes in tax laws affecting
the municipal and asset-backed debt markets. No assurance can be given that
future legislative or regulatory changes might not adversely affect the
results of operations and financial condition of the Company.
 
  The principal executive offices of the Company are located at 113 King
Street, Armonk, New York 10504. The telephone number is (914) 273-4545.

(1) The GAAP loss ratio is the provision for losses and loss adjustment
    expenses divided by net premiums earned, and the GAAP expense ratio is
    underwriting expenses (adjusted for deferred policy acquisition costs) and
    operating expenses (excluding interest expense) divided by net premiums
    earned, in each case calculated in accordance with generally accepted
    accounting principles. The combined ratio is the total of the loss and
    expense ratios (see Note 2 to the Consolidated Financial Statements of
    MBIA Inc. and Subsidiaries).
(2) The SAP loss ratio is the provision for losses and loss adjustment
    expenses divided by net premiums earned, and the SAP expense ratio is
    underwriting expenses divided by net premiums written, in each case

  The proceeds to the Company from the sale of the Shares, net of underwriting
discounts and expenses, are estimated to be approximately $  million. Proceeds
from the sale of the Shares being offered by the Company will be used to
provide additional capital for the future needs of the Company and MBIA Corp.
and for general corporate purposes. The Company will not receive any proceeds
from the sale of the Shares being offered by the Selling Shareholder.

  In May 1987, following the Company's commencement of operations, the Board
of Directors of the Company established the policy of declaring quarterly
dividends on the Common Stock and the Company has paid consecutive quarterly
dividends since then. The amount of dividends payable on Common Stock is
reviewed periodically by the Board of Directors in light of the Company's
earnings, financial condition and capital requirements. It is the policy of
the Board of Directors that the Company retain a portion of its earnings to
support the reasonable growth of the business.
 
  The Company's ability to pay dividends depends on the ability of MBIA Corp.
to declare and distribute dividends to the Company. MBIA Corp.'s ability to
declare dividends is subject to restrictions contained in the New York
Insurance Law. See "Business--Regulation" in the Company's Annual Report on
Form 10-K for the year ended December 31, 1994 (the "1994 Form 10-K"). The
Company expects that such restrictions will not affect the ability of MBIA
Corp. to declare dividends sufficient to support the Company's dividend
policy.

  Of the 3,530,000 shares of Common Stock being offered hereby, 2,860,000
Shares are being sold by the Selling Shareholder. The Selling Shareholder will
receive all of the net proceeds from the sale of these Shares. The following
table sets forth, as of the date of this Prospectus, certain information with
respect to the ownership of shares of Common Stock by the Selling Shareholder.
Daniel P. Kearney, the executive vice president, investments/financial
services of the Selling Shareholder, currently serves on the Company's Board
of Directors. In addition, the Selling Shareholder or its affiliates have
engaged in a variety of material transactions with the Company, including (i)
entering into reinsurance transactions, (ii) providing investment advisory
services to the Company and (iii) providing insurance coverage for the
Company's directors, officers and employees. For further information, see
"Certain Relationships and Related Transactions" in the Company's 1994 Form
10-K. Beginning in January 1996, the Selling Shareholder and its affiliates no
longer provide investment advisory services to the Company.

(1) If the U.S. Underwriters' over-allotment options are exercised in full,
    the Selling Shareholder will sell an additional 260,000 shares of Common
    Stock. As a result, the number of shares of Common Stock beneficially
    owned by the Selling Shareholder after the offering would be 693,009, or

                         DESCRIPTION OF CAPITAL STOCK
 
  The following is a summary of the terms of the Company's Amended and
Restated Certificate of Incorporation.
 
  The Company's authorized capital stock consists of 200,000,000 shares of
Common Stock and 10,000,000 shares of Preferred Stock, par value $1.00 per
share. No shares of Preferred Stock are presently outstanding. The Company
does not presently have outstanding, and the Amended and Restated Certificate
of Incorporation does not authorize, any other classes of capital stock. The
issued and outstanding shares of Common Stock are duly authorized, validly
issued, fully paid and nonassessable.
 
  Holders of shares of Common Stock have no preemptive, redemption or
conversion rights. The holders of Common Stock are entitled to receive
dividends when and as declared by the Board of Directors out of funds legally
available therefor. See "Price Range of Common Stock and Dividends." Upon
liquidation, dissolution or winding up of the Company, the holders of Common
Stock may share ratably in the net assets of the Company after payment in full
to all creditors of the Company and liquidating distributions to holders of
Preferred Stock, if any. Each holder of Common Stock is entitled to one vote
per share on all matters submitted to a vote of shareholders.
 
  The Company's Amended and Restated Certificate of Incorporation requires the
approval of at least 80% of the outstanding shares of Common Stock for the
amendment of certain provisions which describe the factors the Board may
consider in evaluating proposed mergers, sales and other corporate
transactions. Further, as an insurance holding company, the Company is subject
to certain state insurance regulations that require prior approval of a change
of control. See "Business--Regulation" in the Company's 1994 Form 10-K. These
provisions and regulations may discourage attempts to obtain control of the
Company.
 
                                       8
<PAGE>
 
  In the Amended and Restated Certificate of Incorporation the Company elects
not to be subject to the provisions of Sections 33-374a through 33-374c of the
Connecticut Stock Corporation Act. If the Company had not made such elections
these provisions would require the approval of the holders of at least 80% of
the voting power of the outstanding voting stock of the Company, and at least
66 2/3% of the voting power of the outstanding voting stock of the Company
other than voting stock held by certain holders of 10% or more of such voting
power or by certain affiliates of the Company, as a condition for mergers,
liquidations and other business transactions involving the Company and the
holders of 10% or more of such voting power or certain affiliates of the
Company unless certain minimum price and procedural requirements are met.
 
  The Board of Directors has the power, without further vote of shareholders,
to authorize the issue of up to 10,000,000 shares of Preferred Stock and to
fix and determine the terms, limitations and relative rights and preferences
of any shares of Preferred Stock that it causes to be issued. This power
includes the authority to establish voting, dividend, redemption, conversion,
liquidation and other rights of any such shares. No shares of Preferred Stock
have been issued, and the Company has no current plan to issue any such
shares, except as contemplated by the shareholder rights plan described below.
 
  On December 12, 1991, the Company's Board of Directors declared a dividend
distribution of one Preferred Share Purchase Right (a "Right") for each share
of Common Stock. Each Right entitles the registered holder to purchase from
the Company one one-hundredth of a Junior Participating Cumulative Preferred
Share (the "Junior Preferred Stock") of the Company at a price of $160,
subject to certain adjustments to prevent dilution through stock dividends,
splits and combinations and distributions of warrants or other securities or
assets. The Junior Preferred Stock will rank senior to Common Stock, but could
rank junior to other classes of Preferred Stock that might be issued, as to
dividends and liquidating distributions, and will have 100 votes per share,
voting together with Common Stock. Initially, the Rights are attached to
shares of Common Stock and are not represented by separate certificates or
exercisable until the earlier to occur of (a) ten business days following the
public announcement by the Company (the "Shares Acquisition Date") that a
person or group of persons acquired (or obtained the right to acquire)
beneficial ownership of 10% or more of the outstanding Common Stock and (b)
ten business days (or, if determined by the Board of Directors, a later date)
following the announcement or commencement of a tender offer or exchange offer
which, if successful, would result in the bidder owning 10% or more of the
outstanding Common Stock. However, no person shall be deemed to have acquired
or obtained the right to acquire the beneficial ownership of 10% or more of
the outstanding shares of the Company's Common Stock, if the Board of
Directors determines that such acquisition is inadvertent, and such person
promptly divests itself of a sufficient number of shares to be below the 10%
ownership threshold. On such earlier date, Rights certificates would be issued
and mailed to holders of Common Stock. The Rights will expire on December 12,
2001, unless earlier redeemed or exchanged.
 
  If an acquiring person or group acquires beneficial ownership of 10% or more
of the Common Stock (except pursuant to a tender or exchange offer for all of
the outstanding Common Stock determined by a majority of the Company's
independent directors to be fair and in the best interests of the Company and
its shareholders), then each Right (other than those held by the acquiror,
which will become void) will entitle its holder to purchase for $160 (or the
purchase price as then adjusted) that number of shares of Common Stock (or, in
certain circumstances, cash, a reduction in the purchase price, Common Stock,
other securities of the Company, other property or a combination thereof)
having a market value of $320 (or 200% of the adjusted purchase price). If,
after an acquiring person or group so acquires 10% or more of the Common Stock
in a merger or other business combination and (a) the Company shall not be the
surviving or continuing corporation, (b) the Company shall be the surviving or
continuing corporation and all or part of the Shares of Common Stock shall be
changed or exchanged, or (c) 50% or more of the Company's assets, cash flow or
earning power is sold, then proper provision shall be made so that each Right
(other than those held by the acquiror) will entitle its holder to purchase
that number of shares of common stock of the acquiring company which at the
time of such transaction would have a market value of 200% of the then-
effective purchase price.
 
  The Company's Board of Directors may redeem all but not less than all of the
Rights at $0.01 per Right at any time prior to ten business days following the
Shares Acquisition Date. Additionally, at any time after a
 
                                       9
<PAGE>
 
person or group acquires 10% or more but less than 50% of the outstanding
Common Stock, the Company's Board of Directors may exchange the Rights (other
than those held by the acquiror, which will become void), in whole or in part,
at an exchange ratio of one share of Common Stock per Right (subject to
adjustment). The Board of Directors may also amend the Rights at any time
prior to the Shares Acquisition Date. The Company's Rights Plan is designed to
make it more likely that all of the Company's shareholders receive fair and
equal treatment in the event of any unsolicited attempt to acquire the Company
and to guard against the use of coercive tactics to gain control of the
Company. However, the existence of the Company's Rights Plan might discourage
unsolicited merger proposals and unfriendly tender offers and may therefore
deprive shareholders of an opportunity to sell their shares at a premium over
prevailing market prices.
 
  The Company furnishes its shareholders with annual reports containing
financial statements certified by independent public accounants and quarterly
reports containing unaudited quarterly financial statements.
 
                    CERTAIN UNITED STATES TAX CONSEQUENCES
                 TO NON-UNITED STATES HOLDERS OF COMMON STOCK
 
GENERAL
 
  The following is a general discussion of certain United States Federal
income and estate tax consequences of the ownership and disposition of Common
Stock by a person other than (i) a citizen or resident of the United States,
(ii) a corporation, partnership or other entity created or organized in the
United States or under the laws of the United States or of any State or (iii)
an estate or trust whose income is includable in gross income for United
States Federal income tax purposes regardless of its source (referred to
hereafter as a "non-U.S. holder").
 
  The discussion is based on provisions of the Internal Revenue Code of 1986,
as amended (the "Code") and administrative and judicial interpretations as of
the date hereof, all of which are subject to change, possibly with retroactive
effect. Furthermore, this discussion does not consider specific facts and
circumstances that may be relevant to a particular holder's tax position.
Prospective purchasers are urged to consult a tax adviser with respect to the
United States Federal income and estate tax consequences of owning and
disposing of Common Stock, as well as any tax consequences under the laws of
any other taxing jurisdiction.
 
INCOME TAX
 
  DIVIDENDS. Generally, dividends paid to a non-U.S. holder of Common Stock
will be subject to U.S. Federal income tax. Except in the case of dividends
that are effectively connected with the holder's conduct of a trade or
business within the United States, this tax is imposed and withheld at the
rate of 30% of the amount of the dividend, unless reduced by an applicable
income tax treaty. Currently, dividends paid to an address in a foreign
country are presumed to be paid to a resident of such country in determining
the applicability of a treaty for such purposes. However, the Internal Revenue
Service has issued proposed regulations which, if adopted, would require a
non-U.S. holder to provide certain certifications under penalties of perjury
in order to obtain treaty benefits.
 
  Except as may be otherwise provided in an applicable income tax treaty,
dividends which are effectively connected with the non-U.S. holder's conduct
of a trade or business within the United States are subject to tax at ordinary
Federal income tax rates, which tax is not collected by withholding (except as
described below under "Backup Withholding and Information Reporting"). All or
part of any effectively connected dividends received by a foreign corporation
may also, under certain circumstances, be subject to an additional "branch
profits" tax at a 30% rate or such lower rate as may be specified by an
applicable income tax treaty. Non-U.S. holders of Common Stock must comply
with certain certification and disclosure requirements to claim an exception
from withholding under the rules described in this paragraph.
 
  A non-U.S. holder that is eligible for a reduced rate of U.S. withholding
tax pursuant to a tax treaty may obtain a refund of any excess amounts
withheld by filing an appropriate claim for refund with the United States
Internal Revenue Service.
 
                                      10

  DISPOSITION OF COMMON STOCK. Generally, non-U.S. holders will not be subject
to United States Federal income tax (or withholding thereof) in respect of
gain recognized on a disposition of Common Stock unless (i) the gain is
effectively connected with the non-U.S. holder's conduct of a trade or
business within the United States (in which case the "branch profits" tax
described above may also apply if the holder is a foreign corporation), (ii)
in the case of a non-U.S. holder who is a non-resident alien individual and
holds the Common Stock as a capital asset, such holder is present in the
United States for 183 or more days in the taxable year of the sale and certain
other conditions are met; or (iii) the Company is or has been a "United States
real property holding corporation" for Federal income tax purposes (which the
Company does not believe it has been or is currently) and the non-U.S. holder
has held directly or constructively more than 5% of the outstanding Common
Stock within the five-year period ending on the date of the disposition. The
Company currently is not and does not anticipate becoming a "U.S. real
property holding corporation."
 
ESTATE TAX
 
  If an individual non-U.S. holder owns, or is treated as owning, Common Stock
at the time of his or her death, such stock would be subject to U.S. Federal
estate tax imposed on the estates of nonresident aliens, in the absence of a
contrary provision contained in any applicable tax treaty.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  DIVIDENDS. The Company must report annually to the Internal Revenue Service
and to each non-U.S. holder the amount of dividends and other payments
distributed to such non-U.S. holder and any tax withheld with respect to such
holder, regardless of whether withholding is required. Generally, dividends
paid on Common Stock to a non-U.S. holder at an address outside the United
States will be exempt from backup withholding tax and information reporting
requirements related thereto.
 
  BROKER SALES. Payments of proceeds from the sale of Common Stock by a non-
U.S. holder made to or through a foreign office of a broker generally will not
be subject to information reporting or backup withholding. However, sales
through certain foreign offices, including the foreign offices of a U.S.
broker, are subject to information reporting unless the holder certifies its
non-U.S. status under penalties of perjury or otherwise establishes its
entitlement to an exemption. Payments of proceeds from the sale of Common
Stock by a non-U.S. holder to or through a U.S. office of a broker are
currently subject to both information reporting and backup withholding at a
rate of 31% unless the holder certifies its status as a non-U.S. holder under
penalties of perjury or otherwise establishes an exemption.
 
  A non-U.S. holder may obtain a refund of any excess amounts withheld under
the backup withholding rules by filing the appropriate claim for refund with
the IRS.
 
                                 UNDERWRITING

  The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Common Stock
offered hereby are subject to approval of certain legal matters by counsel and
to certain other conditions. If any shares of Common Stock are purchased by
the Underwriters pursuant to the Underwriting Agreement, all such shares
(other than shares covered by the over-allotment option described below) must
be purchased.
 
  The Underwriters have advised the Company and the Selling Shareholder that
they propose to offer the shares of Common Stock directly to the public at the
public offering price set forth on the cover page hereof and to certain
dealers (who may include the Underwriters) at a price which represents a
concession not in excess of $    a share under the public offering price. The
Underwriters may allow, and such dealers may reallow, a concession not in
excess of $    a share to other Underwriters or to certain other dealers.
 
  The Company and the Selling Shareholder have granted the U.S. Underwriters
an option exercisable for 30 days after the date of this Prospectus to
purchase, at the price to the public less the underwriting discounts, as set
forth on the cover page of this Prospectus, up to 100,000 and 260,000
additional shares of Common Stock, respectively, to cover over-allotments, if
any. If the U.S. Underwriters exercise these over-allotment options, the U.S.
Underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof that the number of shares to be
purchased by each of them, as shown in the foregoing table, bears to the
2,830,000 shares of Common Stock offered by the U.S. Underwriters hereby. The
U.S. Underwriters may exercise such options only to cover over-allotments in
connection with this offering.
 
  The Company, the Selling Shareholder and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
  Subject to certain exceptions, each of the Company and the Selling
Shareholder have agreed with the Underwriters not to offer, sell, contract to
sell, grant any option to purchase, or otherwise dispose of any Common Stock
or any securities convertible into or exercisable or exchangeable for Common
Stock (other than the Shares offered hereby) for 90 days from the date of this
Prospectus, without the prior written consent of the U.S. Representatives of
the Underwriters.
 
  Under an Amended and Restated Shareholders' Agreement among the Company, the
Selling Shareholder and certain other founding shareholders and Credit Local

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
  Section 33-320a of the Stock Corporation Act of the State of Connecticut
provides that a corporation shall indemnify a director or officer against
judgments, fines, penalties, amounts paid in settlement and reasonable
expenses actually incurred by him, including attorneys' fees, for actions
brought or threatened to be brought against him in his capacity as a director
or officer, other than actions brought by or in the right of the corporation,
when it is determined by certain disinterested parties that he acted in a
manner reasonably believed to be in the corporation's best interest. In any
criminal action or proceeding, it also must be determined that the director or
officer had no reason to believe that his conduct was unlawful. The director
or officer must also be indemnified when he is successful on the merits in the
defense of a proceeding or in circumstances where a court determines that he
is fairly and reasonably entitled to be indemnified, and the court approves
the amount. In connection with shareholder derivative suits, the director or
officer may not be indemnified unless he is finally adjudged not to have
breached his duty to the corporation or a court has determined that he is
fairly and reasonably entitled to be indemnified, and then for such amount as
the court shall determine. The statute provides that the indemnification
provided thereby is exclusive and cannot be reduced or expanded by charter,
by-law or agreement, although a corporation may procure insurance providing
greater indemnification.
 
  The Company has purchased insurance providing officers and directors of the
Company (and their heirs and other legal representatives) coverage against
certain liabilities arising from any negligent act, error, omission or breach
of duty claimed against them solely by reason of their being such officers and
directors, and providing coverage for the Company against its obligation to
provide indemnification as required by the above-described statute. The
insurance policy has a $50 million aggregate policy limit for any loss or
losses during the policy year.
 
  The Underwriting Agreement filed as Exhibit 1.01 hereto provides for
indemnification of the Company's officers and directors by the Underwriters
under certain circumstances.
 
  The Amended and Restated Shareholders' Agreement among the Company and its
Founding Shareholders provides for indemnification of the shareholders that
are parties thereto under certain circumstances (filed as Exhibit 10.30 to the
Company's Registration Statement on Form S-1 (Registration No. 33-14474)).

ITEM 17. UNDERTAKINGS.
 
  (A) The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  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.
 
  (B) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement 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.
 
  (C) 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 said
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.
