                           FORWARD-LOOKING INFORMATION

     Certain statements included in this prospectus and any documents
incorporated by reference constitute "forward-looking statements" within the
meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act") and Section 21E of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"). These statements relate to future events or our
future financial performance and involve known and unknown risks, uncertainties
and other factors that may cause our actual results to be materially different
from those expressed or implied by any forward-looking statements. These
forward-looking statements may contain information related, but not limited to:

     o    anticipated growth in revenues or earnings per share;

     o    anticipated changes in our business or in the amount of client assets
          under management;

     o    anticipated expense levels and expectations regarding financial market
          conditions;

     o    anticipated future transactions such as acquisitions; and

     o    anticipated performance of recent, pending and future acquisitions.

     In some cases, you can identify forward-looking statements by terminology
such as "may," "will," "could," "would," "should," "expect," "plan,"
"anticipate," "intend," "believe," "estimate," "predict," "potential" or
"continue" or the negative of those terms or other comparable terminology.
These statements are only predictions. Actual events or results may differ
materially due to a number of factors including, but not limited to:

     o    the volatile and competitive nature of the asset management industry;

     o    changes in domestic and foreign economic and market conditions;

     o    the loss of key employees or principals of our current or future
          operating subsidiaries;

     o    the effect of current and future federal, state and foreign regulation
          of the asset management industry, including potential liability under
          applicable securities laws;

                                       4



     o    market, credit and liquidity risks associated with our investment
          management activities;

     o    the impairment of acquired intangible assets and goodwill;

     o    potential restrictions on the business of, and withdrawal of capital
          from, certain of our subsidiaries due to net capital requirements;

     o    the effect of any acquisitions, including our acquisition of
          substantially all of the asset management business of Citigroup
          ("CAM"); and

     o    any unexpected difficulties in, or inability to, integrate the CAM
          business into our existing business, or any unexpected changes in the
          CAM business resulting from the acquisition or otherwise.

     Moreover, we do not nor does any other person, assume responsibility for
the accuracy and completeness of those statements. We have no duty to update any
of the forward-looking statements after the date of this prospectus. In
assessing these forward-looking statements you should carefully consider the
factors discussed under the captions "Management's Discussion and Analysis of
Results of Operations and Financial Condition--Forward Looking Statements" of
our Quarterly Reports on Form 10-Q, "Business--Factors Affecting the Company and
the Financial Services Industry" and "Management's Discussion and Analysis of
Results of Operations and Financial Condition--Forward Looking Statements" in
our most recent Annual Report on Form 10-K and "Factors Affecting the Company
and the Financial Services Industry" in our Current Report on Form 8-K filed on
December 20, 2005, which describe risks and factors that could cause results to
differ materially from those projected in such forward-looking statements.

     We caution the reader that these risk factors may not be exhaustive. We
operate in a continually changing business environment, and new risks emerge
from time to time. Management cannot predict such new risks or the impact of
such new risks on our businesses. Accordingly, forward-looking statements should
not be relied upon as a prediction of actual results.

                                  ERISA MATTERS

     The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
the regulations issued by the Department of Labor under ERISA, the Internal
Revenue Code of 1986, as amended (the "Code"), and the regulations issued by the
Internal Revenue Service under the Code impose certain restrictions on the
following:

     (1)  "employee benefit plans" (as defined in Section 3(3) of ERISA),

     (2)  "plans" described in Section 4975(e)(1) of the Code, including
          individual retirement accounts or Keogh plans,

     (3)  entities whose underlying assets include plan assets by reason of a
          plan's investment in such entities (each of (1), (2) and (3) is
          referred to as a "Plan"), and

     (4)  persons who have certain specified relationships to Plans ("parties in
          interest" under ERISA and "disqualified persons" under the Code).

                                       8




     Both ERISA and the Code prohibit certain transactions between a Plan and
parties in interest or disqualified persons. ERISA also imposes certain duties
on persons who are fiduciaries of Plans that are subject to Title I of ERISA
("ERISA Plans").

     Because of our activities or the activities of our affiliates, we may be
deemed to be a party in interest or disqualified person with respect to a number
of Plans (e.g., those to which we provide brokerage, investment or other
financial services). If our common stock is acquired and held by a Plan with
respect to which we are a party in interest or disqualified person, such
acquisition and holding could be deemed to be a direct or indirect prohibited
transaction, which could result in the imposition of taxes or penalties on the
parties to the prohibited transaction.

     Such transactions may, however, be exempt from the otherwise applicable
taxes and penalties by reason of one or more statutory or administrative
exemptions such as those described below. Such administrative exemptions may
include:

     o    Prohibited Transaction Class Exemption ("PTE") 95-60, 60 FR 35925,
          July 12, 1995, which exempts certain transactions involving insurance
          company general accounts;

     o    PTE 96-23, 61 FR 15975, April 10, 1996, which exempts certain
          transactions directed by an in-house asset manager;

     o    PTE 90-1, 55 FR 2891, January 29, 1990, which exempts certain
          transactions involving insurance company pooled separate accounts;

     o    PTE 91-38, 56 FR 31966, June 12, 1991, which exempts certain
          transactions involving bank collective investment funds; and

     o    PTE 84-14, 49 FR 9494, March 13, 1984, which exempts certain
          transactions entered into on behalf of a Plan by a qualified
          professional asset manager.

         If the conditions of one or more of these exemptions (or some other
applicable exemption) are met, the acquisition and holding of our common stock
by or on behalf of a Plan should be exempt from certain of the prohibited
transaction provisions of ERISA and the Code. It should be noted, however, that
even if such conditions are met, the scope of relief provided by such exemptions
may not necessarily cover all acts that might be construed as prohibited
transactions under ERISA and the Code.

     In addition to the foregoing exemptions, certain insurance company general
accounts, which support policies issued by an insurer on or after December 31,
1998 to or for the benefit of Plans, are allowed to purchase common stock in
reliance upon regulations promulgated by the Department of Labor pursuant to
Section 1460 of the Small Business Job Protection Act of 1996. If such policies
satisfy the Section 1460 regulations, then the insurer will be deemed in
compliance with ERISA's fiduciary requirements and prohibited transaction rules
with respect to those assets of the insurer's general account which supports
such policies.

     Furthermore, Section 404 of ERISA sets forth standards of care for
investment decisions made by a fiduciary of an ERISA Plan. In deciding whether
to invest in our common stock, a fiduciary of an ERISA Plan must take the
following into account, among other considerations:

     o    whether the fiduciary has the authority to make the investment;

                                       9



     o    whether the investment is made in accordance with the written
          documents that govern the ERISA Plan;

     o    whether the investment constitutes a direct or indirect transaction
          with a party in interest or disqualified person;

     o    the composition of the ERISA Plan's portfolio with respect to
          diversification by type of asset;

     o    the ERISA Plan's funding objectives; the tax effects of the
          investment; and

     o    whether under the general fiduciary standards of investment procedure
          and diversification an investment in our common stock is appropriate
          for the ERISA Plan, taking into account the overall investment policy
          of the ERISA Plan, the composition of the ERISA Plan's investment
          portfolio and all other appropriate factors.

     Each person who acquires our common stock or an interest therein will be
deemed by such acquisition or acceptance to have represented and warranted that
either: (i) no assets of a Plan have been used to acquire such security or an
interest therein, or (ii) the purchase and holding of such security or an
interest therein by such person are exempt from the prohibited transaction
restrictions of ERISA and the Code pursuant to one or more prohibited
transaction statutory or class exemptions.

     Prior to making an investment in our common stock, a Plan investor must
determine whether we are a party in interest or disqualified person with respect
to such Plan and, if so, whether such transaction is subject to one or more
statutory or administrative exemptions, including those described above. In
addition, a fiduciary of an ERISA Plan must determine whether the investment is
otherwise a permissible and appropriate investment for the ERISA Plan.
Prospective investors should consult with their legal and other advisors
concerning the impact of ERISA and the Code and the potential consequences of
such investment with respect to their specific circumstances.

     Employee benefit plans that are governmental plans (as defined in Section
3(32) of ERISA) and certain church plans (as defined in Section 3(33) of ERISA)
are not subject to the fiduciary responsibility or prohibited transaction
provisions of ERISA or the Code but may be subject to similar restrictions under
state or local law.

     The above is a summary of some of the material ERISA considerations
applicable to prospective Plan investors. It is not intended to be a complete
discussion, nor is it to be construed as legal advice or a legal opinion.
Prospective Plan investors should consult their own counsel on these matters.

                              PLAN OF DISTRIBUTION

     The common stock being offered by the selling stockholders, or by their
respective pledgees, donees, distributees, transferees, or other successors in
interest, will be sold in one or more transactions by the following means of
distribution (or any combination thereof):

     o    Block trades (which may involve crosses) in which the broker or dealer
          so engaged will attempt to sell the common stock as agent but may
          position and resell a portion of the block as principal to facilitate
          the transaction.

     o    Purchases by a broker or dealer as principal and resale by such broker
          or dealer for its account pursuant to this prospectus.

                                       10



     o    Exchange distributions and/or secondary distributions in accordance
          with the rules of the New York Stock Exchange.

     o    Ordinary brokerage transactions and transactions in which the broker
          solicits purchasers.

     o    Sales in the over-the-counter market.

     o    Through short sales of common stock.

     o    Through the writing of options on common stock.

     o    Distributions to beneficiaries.

     o    Privately negotiated transactions.

     The selling stockholders may from time to time deliver all or a portion of
the shares of common stock offered hereby to cover a short sale or sales or upon
the exercise, settlement or closing of a call equivalent position or a put
equivalent position.

     The sale price to the public may be the market price prevailing at the time
of sale, a price related to the prevailing market price or at any other price as
the selling stockholders determine from time to time. The selling stockholders
shall have the sole and absolute discretion not to accept any purchase offer or
make any sale of common stock if they deem the purchase price to be
unsatisfactory at any particular time.

     The selling stockholders may also sell the common stock directly to market
makers acting as principals and/or broker-dealers acting as agents for
themselves or their customers. Such market makers and broker-dealers may receive
compensation in the form of discounts, concessions, or commissions from the
selling stockholders and/or the purchasers of common stock for whom such
broker-dealers may act as agents or to whom they sell as principals, or both
(which compensation as to a particular broker-dealer might be in excess of
customary commissions). Market makers and block purchasers purchasing the common
stock will do so for their own account and at their own risk. It is possible
that the selling stockholders will attempt to sell shares of common stock in
block transactions to market makers or other purchasers at a price per share
which may be below the then market price. In addition, the selling stockholders
or their successors in interest may enter into hedging transactions with
broker-dealers who may engage in short sales of common stock in the course of
hedging the positions they assume with a selling stockholder.

     The selling stockholders may pledge or grant a security interest in some or
all of the common stock owned by them and, if they default in the performance of
their secured obligations, the pledgees or secured parties may offer and sell
the common stock from time to time pursuant to this prospectus. The selling
stockholders also may transfer and donate the common stock in other
circumstances in which case the transferees, donees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus.

     There can be no assurance that all or any of the common stock offered
hereby will be issued to, or sold by, the selling stockholders.

     The selling stockholders and any broker-dealers that act in connection with
the sale of common stock might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of 

                                       11



the common stock sold by them while acting as principals might be deemed to be
underwriting discounts or commissions under the Securities Act. Because selling
stockholders may be deemed to be "underwriters" within the meaning of Section
2(11) of the Securities Act, the selling stockholders will be subject to the
prospectus delivery requirements of the Securities Act, which may include
delivery through the facilities of the New York Stock Exchange pursuant to Rule
153 under the Securities Act. We have informed the selling stockholders that the
anti-manipulative provisions of Regulation M promulgated under the Exchange Act
of 1934, as amended (the "Exchange Act"), may apply to their sales in the
market. The registration of the common stock under the Securities Act shall not
be deemed an admission by the selling stockholders or Legg Mason that the
selling stockholders are underwriters for purposes of the Securities Act of any
common stock offered pursuant to this prospectus. In addition, under the
securities laws of some states, the shares of common stock may be sold in these
states only through registered or licensed brokers or dealers.

         Under the Exchange Act and the regulations thereunder, any person
engaged in a distribution of the shares of common stock offered by this
prospectus may not simultaneously engage in market making activities with
respect to the common stock during any applicable "cooling off" periods prior to
the commencement of such distribution. In addition, and without limiting the
foregoing, the selling stockholders will be subject to applicable provisions of
the Exchange Act and the rules and regulations thereunder including, without
limitation, Rules 101, 102, 103 and 104, which provisions may limit the timing
of purchases and sales of common stock by the selling stockholders.

     We will not receive any proceeds from the sale of common stock offered by
the selling stockholders. We will pay all expenses of the registration of the
common stock to the Registration Rights Agreement, estimated to be $89,267 in
total, including, without limitation, Securities and Exchange Commission filing
fees and expenses of compliance with state securities or "blue sky" laws. We
will indemnify the selling stockholders against liabilities, including some
liabilities under the Securities Act, in accordance with the Registration Rights
Agreement, or the selling stockholders will be entitled to contribution. We will
be indemnified by the selling stockholders against civil liabilities, including
liabilities under the Securities Act, that may arise from any written
information furnished to us by the selling stockholder for use in this
prospectus, in accordance with the related Registration Rights Agreement, or we
may be entitled to contribution.

     Once sold under the shelf registration statement, of which this prospectus
forms a part, the common stock will be freely tradable in the hands of persons
other than our affiliates.

     Offerings of securities under this prospectus may be subject to Rule 2710,
and separately to Rule 2720 of the Conduct Rules of the National Association of
Securities Dealers, Inc. (NASD). Any such offering will be conducted in
accordance with the applicable provisions of NASD Conduct Rules 2710 and 2720.
In compliance with NASD guidelines, the maximum compensation to broker-dealers
in connection with the sale of the common stock in an offering to which NASD
Conduct Rule 2710 applies will not exceed 8% of the total offering price to the
public of the shares of common stock.

                                  LEGAL MATTERS

     The validity of the Legg Mason common stock offered hereby will be passed
upon for us by Thomas C. Merchant, Esq., our Deputy General Counsel. Mr.
Merchant beneficially owns, or has rights to acquire under our employee benefit
plans, less than one percent of our common stock.

Item 14. Other Expenses of Issuance and Distribution

     The following are the expenses in connection with the issuance and
distribution of the securities being registered, other than underwriting fees
and commissions. All such expenses other than the Securities and Exchange
Commission registration fee are estimates.

Securities and Exchange Commission Registration Fee...............  $24,267
Accounting Fees...................................................  $15,000
Miscellaneous.....................................................  $50,000
Total.............................................................  $89,267

Item 15. Indemnification of Directors and Officers

     The Registrant's by-laws provide for indemnification of any person who is
serving or has served as a director or officer of the Registrant, against all
liabilities and expenses incurred in connection with any action, suit or
proceeding arising out of such service to the full extent permitted under
Maryland law.

     Section 2-418 of the Maryland General Corporation Law establishes
provisions whereby a Maryland corporation may indemnify any director or officer
made a party to an action or proceeding by reason of service in that capacity,
against judgments, penalties, fines, settlements and reasonable expenses
incurred in connection with such action or proceeding unless it is proved that
the director or officer (i) acted in bad faith or with active and deliberate
dishonesty, (ii) actually received an improper personal benefit in money,
property or services or (iii) in the case of a criminal proceeding, had
reasonable cause to believe that his act was unlawful. However, if the
proceeding is a derivative suit in favor of the corporation, indemnification may
not be made if the individual is adjudged to be liable to the corporation. In no
case may indemnification be made until a determination has been reached that the
director or officer has met the applicable standard of conduct. Indemnification
for reasonable expenses is mandatory if the director or officer has been
successful on the merits or otherwise in the defense of any action or proceeding
covered by the indemnification statute. The statute also provides for
indemnification of directors and officers by court order. The indemnification
provided or authorized in the indemnification statute does not preclude a
corporation from extending other rights (indemnification or otherwise) to
directors and officers.

     The Registrant's officers and directors are insured against certain
liabilities under certain policies maintained by the Registrant with aggregate
coverage of $100,000,000.

     The foregoing summaries are subject to the complete text of the statute,
by-laws and agreements referred to above and are qualified in their entirety by
reference thereto.

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 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 

                                      II-2





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
the registration statement or any material change to such information in the
registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) do
not apply if 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.

     (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) 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 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
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 herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     (5) That, for purposes of determining liability under the Securities Act of
1933 to any purchaser:

         (A) Each prospectus filed by a Registrant pursuant to Rule 424(b)(3)
         shall be deemed to be part of the registration statement as of the date
         the filed prospectus was deemed part of and included in the
         registration statement; and

         (B) Each prospectus required to be filed pursuant to Rule 424(b)(2),
         (b)(5) or (b)(7) as part of a registration statement in reliance on
         Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i),
         (vii) or (x) for the purpose of providing the information required by
         Section 10(a) of the Securities Act of 1933 shall be deemed to be part
         of and included in the registration statement as of the earlier of the
         date such form of prospectus is first used after effectiveness or the
         date of the first contract of sale of securities in the offering
         described in the prospectus. As provided in Rule 430B, for liability
         purposes of the issuer and any person that is at that date an
         underwriter, such date shall be deemed to be a new effective date of
         the registration statement relating to the securities in the
         registration statement to which the prospectus relates, and the
         offering of such securities at that time shall be deemed to be the
         initial bona fide offering thereof. Provided, however, that no
         statement made in a registration statement or prospectus that is part
         of the registration statement or made in a document incorporated or
         deemed incorporated by reference into the registration statement or
         prospectus that is part of the registration statement will, as to a
         purchaser with a time of contract of sale prior to such effective date,
         supersede or modify any statement that was made in the registration
         statement or prospectus that was part of the registration statement or
         made in any such document immediately prior to such effective date.

                                      II-3



     That, for the purpose of determining liability of a Registrant under the
Securities Act of 1933 to any purchaser in the initial distribution of the
securities, each undersigned Registrant undertakes that in a primary offering of
securities of an undersigned Registrant pursuant to this registration statement,
regardless of the underwriting method used to sell the securities to the
purchaser, if the securities are offered or sold to such purchaser by means of
any of the following communications, the undersigned Registrant will be a seller
to the purchaser and will be considered to offer or sell such securities to such
purchaser:

          (i)   Any preliminary prospectus or prospectus of the undersigned
          registrant relating to the offering required to be filed pursuant to
          Rule 424;

          (ii)   Any free writing prospectus relating to the offering prepared 
          by or on behalf of an undersigned Registrant or used or referred to by
          an undersigned Registrant;

          (iii) The portion of any other free writing prospectus relating to the
          offering containing material information about the undersigned
          registrant or its securities provided by or on behalf of the
          undersigned Registrant; and

          (iv)  Any other communication that is an offer in the offering made by
          the undersigned Registrant to the purchaser.

     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 provisions set forth in Item 15, 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.

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
