                  DESCRIPTION OF DEBT SECURITIES WE MAY OFFER

   The following description of the terms of the debt securities includes
certain general terms and provisions of the debt securities to which any
prospectus supplement may relate. The particular terms of any debt securities
and the extent to which these general provisions will apply to those debt
securities will be described in the prospectus supplement relating to those
debt securities.

   We may issue debt securities from time to time in series under an indenture
between us and Bank One Trust Company, N.A., as Trustee. The following
summaries of certain provisions of the indenture do not purport to be complete
and are qualified in their entirety by references to the provisions of the
indenture. Since this is only a summary, it does not contain all of the
information which may be important to you. A copy of the entire indenture is an
exhibit to the registration statement of which this prospectus is a part.
Wherever we use defined terms that are not defined below, those terms shall
have the meanings assigned to them in the indenture. We are incorporating those
defined terms herein by reference. If we issue subordinated debt, it may be
issued either under the same indenture as for senior debt or another indenture
in substantially the same form.

General

   The indenture does not limit the amount of debt securities that we may
issue. The indenture provides that debt securities may be issued up to the
principal amount which we authorize from time to time. We may reopen a
previously issued series of debt securities and issue additional debt
securities of that series without the consent of the holders of debt securities
of that particular series.

   The indenture allows us to issue debt securities in one or more separate
series. The prospectus supplement relating to any particular series of debt
securities that we offer will describe the specific amounts, prices and terms
of those debt securities. These terms may include:

  . the designation, issue date, currency or currency unit of payment, if
    other than United States dollars, and authorized denominations of the
    debt securities, if other than US$1,000 and integral multiples;

  . the aggregate principal amount offered and any limit on any future issues
    of additional debt of the same series;

  . the date or dates on which the series of debt securities will mature,
    which may be fixed or extendible;

  . any interest rate or rates, or the method of determining those rates;

  . the dates on which any interest will be payable;

  . if the debt securities are to be subordinated in right of payment to any
    other securities, the terms of subordination;

  . the terms of any mandatory or optional redemption, including any sinking,
    purchase or analogous fund, and any purchase at the option of Holders,
    including whether any such purchase may be paid in cash, common stock or
    other securities or property;

  . the terms of any mandatory or optional conversion or exchange provisions;

  . whether debt securities of the series are to be issued in the form of
    global securities and, if so, the identity of the depositary with respect
    to such global securities; and

  . any other specific terms.

   Unless we set forth or specify otherwise in the prospectus supplement:

  . interest on outstanding debt securities will be paid to Holders of record
    on the date which is 15 days prior to the date such interest is to be
    paid;


                                       6


  . the principal amount of the debt securities will be payable at the
    corporate trust office of the Trustee in Chicago, Illinois;

  . the debt securities may be presented for transfer or exchange at the
    corporate trust office of the Trustee, subject to the limitations
    provided in the indenture, without any service charge, but we may require
    payment of a sum sufficient to cover any tax or other governmental
    charges payable in connection with transfer or exchange.

   Debt securities may be issued under the indenture as Original Issue Discount
Securities to be offered and sold at a substantial discount below their stated
principal amount and which may bear no interest or interest at a rate which is
below the market rate. Federal income tax consequences and other special
considerations applicable to any Original Issue Discount Securities will be
described in the prospectus supplement relating to those securities. "Original
Issue Discount Securities" means debt securities that provide for an amount
less than their principal amount to be due and payable upon a declaration of
acceleration of their maturity upon the occurrence of an event of default and
its continuation.

Ranking

   We may issue debt securities that are either senior or subordinated in right
of payment to other securities. If we issue subordinated debt securities, the
terms of subordination will be set forth in the related prospectus supplement.

   We are a holding company and our principal source of cash is dividends from
our subsidiaries. Applicable state insurance laws restrict the amount of cash
dividends and other distributions certain of our subsidiaries may pay. We
describe these restrictions in general terms in the notes to our financial
statements included in our Report on Form 10-K incorporated by reference in
this prospectus. See "Where You Can Find More Information". Also, because we
are a holding company, our rights and the rights of our creditors, including
the holders of our debt securities, and our shareholders to participate in any
distribution of assets of any subsidiary upon the subsidiary's liquidation or
reorganization or otherwise is subject to the prior claims of the subsidiary's
creditors, except to the extent that we may be a creditor with recognized
claims against the subsidiary. As of March 31, 2001, our subsidiaries had
approximately $86.9 billion of total indebtedness and other liabilities, while
we had $40.0 million of total indebtedness. The indenture does not limit our
ability or the ability of any of our subsidiaries to incur additional
indebtedness, including secured indebtedness.

Mergers and Similar Transactions

   We are generally permitted to merge or consolidate with another corporation
or other entity. We are also permitted to sell our assets substantially as an
entirety to another corporation or other entity. With regard to any series of
debt securities, however, the indenture prohibits us from taking any of these
actions unless all the following conditions are met:

  . if we consolidate with or merge into another corporation or convey or
    transfer our properties and assets substantially as an entirety to any
    person, the successor assumes our obligations under the debt securities;

  . immediately after the transaction, no event of default occurs and
    continues; and

  . we meet other conditions specified in the indenture.

   If the conditions described above are satisfied with respect to the debt
securities, we will not need to obtain the approval of the holders of those
debt securities in order to merge or consolidate or to sell our assets. Also,
these conditions will apply only if we wish to merge or consolidate with
another entity or sell our assets substantially as an entirety to another
entity. We will not need to satisfy these conditions if we enter into other
types of transactions, including any transaction in which we acquire the stock
or assets of another entity, any transaction that involves a change of control
of our company but in which we do not merge or consolidate and

                                       7


any transaction in which we sell less than substantially all our assets. Also,
if we merge, consolidate or sell our assets substantially as an entirety and
the successor is a non-U.S. entity, neither we nor any successor would have any
obligation to compensate you for any resulting adverse tax consequences
relating to your debt securities.

   Upon any consolidation or merger, or any conveyance or transfer of the
properties and assets of our company, substantially as an entirety as set forth
above, the successor Person formed by such consolidation or into which our
company is merged or to which such conveyance or transfer is made shall succeed
to, and be substituted for, and may exercise every right and power of our
company under the indenture with the same effect as if the successor had been
named as our company in the indenture. In the event of any conveyance or
transfer, we, as the predecessor, shall be discharged from all obligations and
covenants under the indenture and the debt securities and may be dissolved,
wound up or liquidated.

   Other than the restrictions in the indenture relating to mergers and similar
transactions described above, the indenture and the debt securities do not
contain any covenants or other provisions designed to afford Holders of debt
securities protection in the event of a recapitalization or highly leveraged
transaction involving our company. Any additional covenants of our company
pertaining to a series of debt securities will be set forth in a prospectus
supplement relating to that series of debt securities.

Certain Definitions

   The following are some of the terms defined in the indenture:

   "Consolidated Subsidiary" means as at any date, or for any period, any
subsidiary the accounts of which are consolidated with those of Berkshire
Hathaway in accordance with generally accepted accounting principles in our
consolidated financial statements as of such date or for such period.

   "Holder" means a Person in whose name a security is registered in the
Security Register.

   "Person" means any individual, corporation, partnership, limited liability
company, joint venture, association, joint-stock company, trust, unincorporated
organization or government or any agency or political subdivision thereof.

   "Security Register" means the register or registers we shall keep or cause
to be kept, in which we shall provide for the registration of securities, or of
securities of a particular series, and of transfers of securities or of
securities of such series.

   "Subsidiary" means, with respect to any Person, any corporation more than
50% of the voting stock of which is owned directly or indirectly by such
Person.

   "U.S. Government Obligation" means:

     (1) any security which is either:

      . a direct obligation of the United States of America for the payment
        of which the full faith and credit of the United States of America
        is pledged or

      . an obligation of a Person controlled or supervised by and acting as
        an agency or instrumentality of the United States of America the
        payment of which is unconditionally guaranteed as a full faith and
        credit obligation of the United States of America and

     which, in either case, is not callable or redeemable at the option of
  the issuer thereof, and

     (2) any depositary receipt issued by a bank, as defined in Section
  3(a)(2) of the Securities Act of 1933, as amended, as custodian with
  respect to any U.S. Government Obligation specified in clause (1) above and
  held by such bank for the account of the holder of such depositary receipt,
  or with

                                       8


  respect to any specific payment of principal of or interest on any U.S.
  Government Obligation which is specified in clause (1) above and so held by
  such bank, provided, that (except as required by law) such custodian is not
  authorized to make any deduction from the amount received by the custodian
  in respect of the U.S. Government Obligation or the specific payment of
  principal or interest evidenced by such depositary receipt.

Defeasance and Covenant Defeasance

   Unless we say otherwise in the applicable prospectus supplement, the
provisions for full defeasance and covenant defeasance described below apply to
each series of debt security that we issue.

   Full Defeasance. If we establish a trust and deliver to the Trustee a legal
opinion of our counsel, as described below, the indenture allows us to legally
release ourselves from all payment and other obligations on any debt
securities. This is called full defeasance. For us to do so, each of the
following must occur:

  . We must deposit in trust for the benefit of the Holders of those debt
    securities a combination of cash and/or U.S. Government Obligations that
    will generate enough cash to make interest, principal and any other
    payments on those debt securities on their various due dates; and

  . We must deliver to the Trustee a legal opinion of our counsel that there
    has been a change in current U.S. federal tax law or an Internal Revenue
    Service ruling that lets us make the above deposit without causing the
    Holders to be taxed on those debt securities any differently than if we
    did not make the deposit and repaid those debt securities as originally
    scheduled. Under current federal tax law, the deposit and our legal
    release from your debt security would be treated as though we took back
    your debt security and gave you your share of the cash and notes or bonds
    deposited in trust. In that event, you could recognize gain or loss on
    your debt security.

   If we ever fully defeased your debt security, you would have to rely solely
on the trust deposit for payments on your debt security. You would not be able
to look to us for payment in the event of any shortfall.

   Covenant Defeasance. The indenture allows us to make the same type of
deposit described above and be released from all restrictive covenants relating
to any debt securities. This is called covenant defeasance. In that event, you
would lose the protection of those restrictive covenants. In order to achieve
covenant defeasance for any debt securities, we must do both of the following:

  . We must deposit in trust for the benefit of the Holders of those debt
    securities a combination of cash and/or U.S. Government Obligations that
    will generate enough cash to make interest, principal and any other
    payments on those debt securities on their various due dates; and

  . We must deliver to the Trustee a legal opinion of our counsel confirming
    that under current U.S. federal income tax law we may make the above
    deposit without causing the Holders to be taxed on those debt securities
    any differently than if we did not make the deposit and repaid those debt
    securities as originally scheduled.

   If we accomplish covenant defeasance with regard to your debt security, the
following provisions of the indenture and your debt security would no longer
apply:

  . our covenant described in "Mergers and Similar Transactions" above;

  . any additional covenants that a prospectus supplement may state are
    applicable to your debt security; and

  . the events of default resulting from a breach of covenants, described
    below under "Events of Default, Notice and Waiver."

   If we accomplish covenant defeasance with regard to your debt security, you
can still look to us for repayment of your debt security in the event of any
shortfall in the trust deposit. You should note, however, that

                                       9


if one of the remaining events of default occurred, such as our bankruptcy, and
your debt security became immediately due and payable, there may be a
shortfall. Depending on the event causing the default, you may not be able to
obtain payment of the shortfall.

Events of Default, Notice and Waiver

   The indenture provides that, if an Event of Default with respect to any
series of debt securities has happened and is continuing, either the Trustee or
the Holders of 25% in aggregate principal amount of the outstanding debt
securities of the series (or 25% in aggregate principal amount of all
outstanding debt securities under the indenture, in the case of certain Events
of Default affecting all series of debt securities under the indenture), may
declare the principal of all the debt securities of the series to be due and
payable immediately.

   The indenture defines "Events of Default" in respect of any series of debt
securities as any:

  . default for thirty (30) days in payment of any interest installment or
    the deposit of any sinking fund payment with respect to the series;

  . default in payment of principal of, or premium, if any, on debt
    securities of the series when due at their stated maturity;

  . default for sixty (60) days after notice to us by the Trustee or by
    Holders of 10% in aggregate principal amount of the outstanding debt
    securities of the series in the performance of any covenant pertaining to
    debt securities of the series;

  . failure to pay when due at maturity or a default that results in the
    acceleration of maturity of any other indebtedness of ours or any of our
    Consolidated Subsidiaries (excluding non-recourse debt) having an
    aggregate principal amount outstanding of at least $50,000,000, unless
    the indebtedness is discharged or the acceleration is rescinded or
    annulled, in each case within 15 days after written notice of default is
    given to us by the Trustee or the Holders of at least 25% in principal
    amount of the outstanding debt securities of the series; and

  . certain events of bankruptcy, insolvency and reorganization with respect
    to us.

   Any additions, deletions or other changes to the Events of Default which
will be applicable to a series of debt securities will be described in the
prospectus supplement relating to that series of debt securities.

   The indenture provides that the Trustee will, within 90 days after the
occurrence of a default with respect to any series of debt securities, provide
notice to the Holders of those debt securities of all defaults known to it;
provided, however, the Trustee will be protected in withholding notices of
defaults other than payment defaults if the Trustee in good faith determines
that the withholding of notice is in the interests of the Holders of that
series of debt securities. The term "default" for the purpose of this provision
means the happening of any of the Events of Default specified above, except
that any grace period or notice requirement is eliminated.

   The indenture contains provisions entitling the Trustee to be indemnified by
the Holders of the debt securities before proceeding to exercise any right or
power under the indenture at the request of Holders of the debt securities.

   The indenture provides that the Holders of a majority in aggregate principal
amount of the outstanding debt securities of any series may direct the time,
method and place of conducting proceedings for remedies available to the
Trustee or exercising any trust or power conferred on the Trustee in respect of
such series, subject to certain conditions.

   In certain cases, the Holders of not less than a majority in principal
amount of the outstanding debt securities of any series may waive, on behalf of
the Holders of all debt securities of such series, any past default or Event of
Default with respect to the debt securities of that series except, among other
things, an otherwise uncured payment default relating to any of the debt
securities of that series.

                                       10


   The indenture includes a covenant that we will file annually with the
Trustee a certificate of no default or specifying any default that exists.

Modification of the Indenture

   We and the Trustee may, without the consent of the Holders of the debt
securities, enter into indentures supplemental to the indenture for one or
more of the following purposes, among others:

     (1) to evidence the succession of another Person to us, and the
  assumption by that successor of our company's obligations under the
  indenture and the debt securities of any series;

     (2) to add to the covenants of our company, or to surrender any rights
  or powers of our company, for the benefit of the Holders of debt securities
  of any or all series;

     (3) to cure any ambiguity, or correct any inconsistency in the indenture
  or to make any other provisions with respect to matters or questions
  arising under this indenture;

     (4) to establish the form or terms of any series of debt securities;

     (5) to evidence and provide for the acceptance of any successor Trustee
  with respect to one or more series of debt securities or to facilitate the
  administration of the trusts under the indenture by one or more trustees in
  accordance with the indenture;

     (6) to provide any additional Events of Default; and

     (7) to provide for the issuance of debt securities in bearer, coupon or
  fully registered form.

   The indenture contains provisions permitting us and the Trustee, with the
consent of the Holders of not less than 51% in principal amount of the
outstanding debt securities of all series to be affected voting as a single
class, to execute supplemental indentures by adding any provisions to or
changing or eliminating any of the provisions of the indenture or modifying
the rights of the Holders of the debt securities of such series to be
affected, except that no such supplemental indenture may, without the consent
of the Holders of affected debt securities, among other things:

  . change the fixed maturity of any debt securities;

  . reduce the principal amount of any debt securities; or

  . reduce the rate or extend the time of payment of interest on any debt
    securities.

The Trustee

   Bank One Trust Company, N.A. is the Trustee under the indenture. The
Trustee's affiliate, Bank One, N.A., is a depository for funds and performs
other services for, and transacts other banking business with, us or our
subsidiaries in the normal course of business.

Governing Law

   The indenture will be governed by, and construed in accordance with, the
laws of the State of New York.

Global Securities

   We may issue debt securities in the form of global securities. A global
security is a security, typically held by a depositary (e.g., DTC, Euroclear
or Clearstream, Luxembourg), that represents the beneficial interests of a
number of purchasers of the security. The specific terms of the depositary
arrangement with respect to a series of debt securities will be described in
the applicable prospectus supplement. We anticipate that the following
provisions will apply to all depositary arrangements for global securities.

                                      11


   We will deposit global securities with the depositary identified in the
prospectus supplement. After we issue a global security, the depositary will
credit on its book-entry registration and transfer system the respective
principal amounts of the debt securities represented by the global security to
the accounts of persons that have accounts with the depositary. These account
Holders are known as "participants." The underwriters or agents participating
in the distribution of the debt securities will designate the accounts to be
credited; we will designate the accounts if the debt securities are offered and
sold directly by us. Only a participant or a person that holds an interest
through a participant may be the beneficial owner of a global security.
Ownership of beneficial interests in the global security will be shown on, and
the transfer of that ownership will be effected only through, records
maintained by the depositary and its participants.

   We and the Trustee will treat the depositary or its nominee as the sole
owner or Holder of the debt securities represented by a global security. Except
as set forth below and in the indenture, owners of beneficial interests in a
global security will not be entitled to have the debt securities represented by
the global security registered in their names. They also will not receive or be
entitled to receive physical delivery of the debt securities in definitive form
and will not be considered the owners or Holders of the debt securities.

   Principal, any premium and any interest payments on debt securities
represented by a global security registered in the name of a depositary or its
nominee will be made to the depositary or its nominee as the registered owner
of the global security. None of us, the Trustee or any paying agent will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the global
security or for maintaining, supervising or reviewing any records relating to
the beneficial ownership interests.

   We expect that the depositary, upon receipt of any payments, will
immediately credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of the global security as shown on the depositary's records. We also expect
that payments by participants to owners of beneficial interests in the global
security will be governed by standing instructions and customary practices, as
is the case with the securities held for the accounts of customers registered
in "street names," and will be the responsibility of the participants.

   If the depositary is at any time unwilling or unable to continue as
depositary and a successor depositary is not appointed by us within ninety
days, we will issue registered securities in exchange for the global security.
In addition, we may at any time in our sole discretion determine not to have
the debt securities of any series represented by global securities. In that
event, we will issue debt securities of that series in definitive form in
exchange for the global securities.

                                       12


                              PLAN OF DISTRIBUTION

   We may sell the debt securities:

     (1) through agents;

     (2) through underwriters;

     (3) to dealers;

     (4) directly to one or more purchasers; or

     (5) through a combination of any of these methods of sale.

Through Agents

   The debt securities may be sold through agents designated by us. Unless
otherwise indicated in a prospectus supplement, the agents will use their best
efforts to solicit purchases for the period of their appointment.

Through Underwriters

   If we use underwriters in the sale, the underwriters will acquire the debt
securities for their own account. The underwriters may resell the debt
securities in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of
sale. The underwriters' obligation to purchase the debt securities will be
subject to certain conditions. The underwriters will be obligated to purchase
all the debt securities of the series offered if any of those securities are
purchased. Any initial public offering price and any discounts or concessions
allowed or re-allowed or paid to dealers may be changed from time to time.

To Dealers

   If a dealer is used in the sale of debt securities, we will sell the debt
securities to the dealer, as principal. The dealer may then resell those
securities to the public at varying prices to be determined by the dealer at
the time of resale.

Direct Sales

   We may also sell the debt securities directly to institutional investors or
others. In this case, no underwriters or agents would be involved.

Delayed Delivery Contracts

   We may authorize underwriters, dealers and agents to solicit offers by
certain institutional investors to purchase debt securities under contracts
providing for payment and delivery on a future date specified in the prospectus
supplement. The prospectus supplement will also describe the public offering
price for the securities and the commission payable for solicitation of these
delayed delivery contracts. Delayed delivery contracts will contain definite
fixed price and quantity terms. The obligations of a purchaser under these
delayed delivery contracts will be subject to only two conditions:

  . that the institution's purchase of the securities at the time of delivery
    of the securities is not prohibited under the law of any jurisdiction to
    which the institution is subject; and

  . that we shall have sold to the underwriters the total principal amount of
    the offered securities, less the principal amount covered by the delayed
    delivery contracts.

                                       13


General Information

   Underwriters, dealers, agents and direct purchasers that participate in the
distribution of the debt securities may be underwriters as defined in the
Securities Act of 1933, as amended (the "Securities Act"), and any discounts or
commissions they receive from us and any profit on the resale of the debt
securities by them may be treated as underwriting discounts and commissions
under the Securities Act. Any underwriters, dealers or agents will be
identified and their compensation described in a prospectus supplement.

   We may have agreements with the underwriters, dealers and agents to
indemnify them against certain civil liabilities, including liabilities under
the Securities Act, or to contribute with respect to payments which the
underwriters, dealers or agents may be required to make.

   Underwriters, dealers and agents may engage in transactions with, or perform
services for, us or our subsidiaries in the ordinary course of their
businesses.

   The place and time of delivery of any debt securities will be described in
the applicable prospectus supplement.

                                 LEGAL MATTERS

   Certain legal matters relating to the debt securities will be passed upon by
Munger, Tolles & Olson LLP, Los Angeles, California, and for the underwriters,
if any, by Cravath, Swaine & Moore, New York, New York. Ronald L. Olson, a
partner of Munger, Tolles & Olson LLP, is one of our directors. Mr. Olson and
those attorneys at Munger, Tolles & Olson LLP who will represent Berkshire
Hathaway in this offering of debt securities beneficially own 157 shares of our
Class A Common Stock and 347 shares of our Class B Common Stock in the
aggregate.

Item 15. Indemnification of Directors and Officers

   Section 145 of the General Corporation Law of Delaware empowers Berkshire to
indemnify, subject to the standards therein prescribed, any person in
connection with any action, suit or proceeding brought or threatened by reason
of the fact that such person is or was a director, officer, employee or agent
of Berkshire or is or was serving as such with respect to another corporation
or other entity at the request of Berkshire. Section 10 of Berkshire's By-Laws
provides that Berkshire shall, to the fullest extent permitted by Section 145
of the General Corporation Law of Delaware, indemnify directors and officers of
Berkshire from and against any and all of the expenses, liabilities or other
matters referred to in or covered by said Section. Additionally, as permitted
by said Section and Berkshire's By-Laws, Berkshire has entered into
indemnification agreements with each of its directors and officers. The
description of such indemnification agreements in paragraphs 2 and 3 of Item 15
of our Registration Statement on Form S-3 (Registration No. 333-41686) filed
with the Commission on July 18, 2000 is incorporated herein by reference.

   As permitted by Section 102 of the General Corporation Law of Delaware,
Berkshire's Restated Certificate of Incorporation includes as Article Eighth
thereof a provision eliminating, to the extent permitted by Delaware law, the
personal liability of each director of Berkshire to Berkshire or any of its
shareholders for monetary damages resulting from breaches of such director's
fiduciary duty of care.

Item 17. Undertakings.

   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 this 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 this 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; and

       (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in this Registration Statement
    or any material change to such information in this Registration
    Statement;

  provided, however, that subparagraphs (i) and (ii) above do not apply if
  the information required to be included in a post-effective amendment by
  those paragraphs is contained in periodic reports filed by the Registrants
  pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
  1934 that are incorporated by reference in this Registration Statement.

     (2) That, for the purpose of determining any liability under the
  Securities Act, 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; and

     (4) That, for purposes of determining any liability under the Securities
  Act, each filing of the registrant's annual report pursuant to Section
  13(a) or 15(d) of the Exchange Act 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.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities 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
Securities Act and will be governed by the final adjudication of such issue.
