(1) Pursuant to Rule 457(o) and General Instruction II.D. of Form S-3 under the
    Securities Act of 1933, the table does not specify by each class information
    as to the amount to be registered, the proposed maximum aggregate price per
    unit or the proposed maximum aggregate offering price. For each class of
    security, the amount to be registered, the proposed maximum aggregate price
    per unit and the proposed maximum aggregate offering price will be
    determined from time to time by us in connection with the issuance of the
    securities registered hereunder. In no event will the aggregate initial
    offering price of all securities issued from time to time pursuant to the
    prospectus contained in this registration statement exceed $200,000,000 or
    the equivalent thereof in one or more foreign currencies, foreign currency
    units or composite currencies. The securities registered hereunder may be
    sold separately, together or as units with other securities registered
    hereunder.

(2) Estimated solely for purposes of determining the registration fee pursuant
    to Rule 457(o) under the Securities Act of 1933, which permits the
    registration fee to be calculated on the basis of the maximum aggregate
    offering price of all securities listed.

(3) If Trustmark Corporation elects to offer fractional interests in shares of
    preferred stock, depositary shares, evidenced by depositary receipts issued
    pursuant to a deposit agreement, will be distributed to those persons
    acquiring the fractional interests, and the shares of preferred stock will
    be issued to the depositary under such deposit agreement.

(4) If any debt securities are issued at an original issue discount, then the
    offering price shall be in such greater principal amount as shall result in
    an aggregate initial offering price not to exceed $200,000,000 less the
    dollar amount of any securities previously issued hereunder (including other
    debt securities issued at an original issue discount, which shall be treated
    as described in this note 4).

(5) Junior subordinated debt securities may be purchased by any of Trustmark
    Capital Trust I, Trustmark Capital Trust II, Trustmark Capital Trust III and
    Trustmark Capital Trust IV with the gross proceeds of the sale of the trust
    preferred securities of the applicable trust, together with the proceeds
    received from Trustmark Corporation for the common securities to be issued
    by the applicable trust to Trustmark Corporation. No additional
    consideration will be received by Trustmark Corporation for such junior
    subordinated debt securities. Such junior subordinated debt securities may
    later be distributed for no additional consideration to the holders of trust
    preferred securities of the applicable trust upon the occurrence of certain
    events described in the applicable trust agreement of such trust.

(6) Trustmark Corporation is also registering pursuant to this Registration
    Statement Trustmark Corporation's guarantees and other obligations that it
    may undertake with respect to trust preferred securities issued by any of
    Trustmark Capital Trust I, Trustmark Capital Trust II, Trustmark Capital
    Trust III and Trustmark Capital Trust IV. Pursuant to Rule 457(n), no
    separate consideration will be received for any such guarantee or any other
    such obligation.

    THE REGISTRANTS HEREBY AMEND THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANTS
SHALL FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF
THE SECURITIES ACT, OR UNTIL THIS REGISTRATION STATEMENT SHALL BECOME EFFECTIVE
ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(a), MAY
DETERMINE.


The information in this prospectus is not complete and may be changed. We may
not sell these securities until the registration statement filed with the
Securities and Exchange Commission is effective. This prospectus is not an offer
to sell these securities and it is not soliciting an offer to buy these
securities in any state where the offer or sale is not permitted.

     This prospectus is part of a registration statement we filed with the
Securities and Exchange Commission. You should rely only on the information we
have provided or incorporated by reference in this prospectus or any prospectus
supplement. We have not authorized anyone to provide you with additional or
different information. We are not making an offer of these securities in any
jurisdiction where the offer is not permitted. You should assume that the
information in this prospectus or any prospectus supplement is accurate only as
of the date on the front of the document and that any information we have

                             ABOUT THIS PROSPECTUS

     This prospectus is part of a Registration Statement on Form S-3 that we
filed with the Securities and Exchange Commission (the "SEC") utilizing a
"shelf" registration process. Under this shelf process, we may offer from time
to time any combination of securities described in this prospectus in one or
more offerings up to a total amount of $200,000,000. This prospectus provides
you with a general description of the securities we may offer. Each time we use
this prospectus to offer securities, we will provide a prospectus supplement
that will contain specific information about the terms of that offering.

     Pursuant to Rule 3-10 of Regulation S-X promulgated by the SEC, we are not
required to include in this prospectus separate financial statements of
Trustmark Capital Trust I, which we refer to as "TRMK Trust I," Trustmark
Capital Trust II, which we refer to as "TRMK Trust II," Trustmark Capital Trust
III, which we refer to as "TRMK Trust III," or Trustmark Capital Trust IV, which
we refer to as "TRMK Trust IV," because:

     - the sum of all of each of their respective equity interests are owned by
       Trustmark, either directly or through wholly-owned subsidiaries of
       Trustmark, other than (i) securities that are guaranteed by Trustmark
       and, if applicable, other 100%-owned subsidiaries of Trustmark and (ii)
       securities that guarantee securities issued by Trustmark and, if
       applicable, other 100% owned subsidiaries of Trustmark;

     - Trustmark files periodic and other reports with the SEC pursuant to the
       Securities Exchange Act of 1934 (the "Securities Exchange Act");

     - none of TRMK Trust I, TRMK Trust II, TRMK Trust III or TRMK Trust IV has
       operations other than the issuance of the trust preferred securities and
       trust common securities and investment of funds in Trustmark or its
       subsidiaries; and

     - Trustmark will, to the extent funds are available, irrevocably guarantee
       the obligations of TRMK Trust I, TRMK Trust II, TRMK Trust III and TRMK
       Trust IV, and the rights of holders of their securities, and no
       subsidiary of Trustmark will guarantee those obligations.

     Because TRMK Trust I, TRMK Trust II, TRMK Trust III and TRMK Trust IV
(which we refer to collectively as the "TRMK Trusts" or the "trusts") are
permitted to omit financial statements, pursuant to Rule 12h-5 under the
Securities Exchange Act, they are not subject to the information reporting
requirements of that act.

     This prospectus provides you with a general description of the securities
we may offer. Each time we sell such securities, we will provide a prospectus
supplement containing specific information about the terms of the securities
being offered, and if we sell securities through agents, underwriters or
dealers, the names of such agents, underwriters or dealers and any fees,
discounts and commissions to be paid to them. The prospectus supplement may
include a discussion of any risk factors or other special considerations
applicable to those securities. The prospectus supplement may also add, update
or change information in this prospectus. If there is any inconsistency between
the information in this prospectus and any prospectus supplement, you should
rely on the information in the prospectus supplement. You should read both this
prospectus and any prospectus supplement together with the additional
information described under the heading "Where You Can Find More Information;
Documents Incorporated By Reference."

     The registration statement containing this prospectus, including the
exhibits to the registration statement, provides additional information about us
and the securities offered under this prospectus. The registration statement,
including the exhibits, can be read at the SEC website or at the SEC offices
mentioned under the heading "Where You Can Find More Information; Documents
Incorporated By Reference." Additional documents that contain the specific terms
of certain securities we may offer may subsequently be filed as exhibits to this
registration statement or incorporated into the prospectus or prospectus
supplement by reference to documents we file with the SEC.

     The prospectus also incorporates business and financial information about
us that is not included or delivered with this document. YOU MAY REQUEST AND
OBTAIN THIS INFORMATION FREE OF CHARGE BY WRITING TO

                          ABOUT TRUSTMARK CORPORATION

     Trustmark is a multi-bank holding company headquartered in Jackson,
Mississippi, incorporated under the Mississippi Business Corporation Act on
August 5, 1968, and commenced doing business in November 1968. Trustmark
operates as a financial services organization providing banking and financial
solutions to corporate, institutional and individual customers predominantly
within the states of Mississippi and Tennessee. Our principal executive offices
are located at 248 East Capitol Street, Jackson, Mississippi, 39201, and our
telephone number is (601) 208-5111.

                                THE TRMK TRUSTS

     Each TRMK Trust is a statutory trust created under the Delaware Statutory
Trust Act. Each TRMK Trust will be governed by a declaration of trust (as it may
be amended and restated from time to time) among the trustees of each trust and
Trustmark and a certificate of trust, in effect at or prior to the date hereof,
filed with the Secretary of State of the State of Delaware. Each declaration
will be qualified under the Trust Indenture Act of 1939.

     For the reasons set forth under the caption "About This Prospectus," we are
not required to include separate financial statements of the TRMK Trusts in this
prospectus and none of the trusts are subject to the information reporting
requirements of the Securities Exchange Act.

     Each of the trusts will exist primarily for the purposes of (i) issuing its
trust preferred and trust common securities; (ii) investing the proceeds from
the sale of its securities in Trustmark's debt securities; and (iii) engaging in
only such other activities as are necessary or incidental to issuing its
securities and purchasing and holding Trustmark's debt securities.

     When a trust issues its trust preferred securities, you and the other
holders of the trust preferred securities will own all of the issued and
outstanding trust preferred securities of the trust. Trustmark will acquire all
of the issued and outstanding trust common securities of each trust,
representing an undivided beneficial interest in the assets of each trust of at
least 3%. Wilmington Trust Company, acting in its capacity as guarantee trustee,
will hold for your benefit a trust preferred securities guarantee issued by
Trustmark, which will be separately qualified under the Trust Indenture Act of
1939.

     Each of the trusts will initially have five trustees. Three of the trustees
will be individuals each of whom is an officer or employee of Trustmark. The
fourth trustee will be Wilmington Trust Company, which will serve as the
property trustee under the declaration of trust for purposes of the Trust
Indenture Act of 1939. The fifth trustee will be Wilmington Trust Company, which
will serve as Delaware trustee and has its principal place of business in the
State of Delaware.

     Unless otherwise provided in the applicable prospectus supplement, because
Trustmark will own all of the trust common securities of each trust, Trustmark
will have the exclusive right to appoint, remove or replace trustees and to
increase or decrease the number of trustees. The term of a trust will be
described in the applicable prospectus supplement, but may dissolve earlier as
provided in the applicable declaration of trust.

     The rights of the holders of the trust preferred securities of a trust,
including economic rights, rights to information and voting rights, and the
duties and obligations of the trustees of a trust, will be contained in and
governed by the declaration of trust of that trust (as it may be amended and
restated from time to time), the Delaware Business Trust Act and the Trust
Indenture Act of 1939.

     The address of each trust is 248 East Capitol Street, Jackson, Mississippi,
39201, and the telephone number of each trust at that address is (601) 208-5111.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Some of the statements in this prospectus and the documents incorporated by
reference are not statements of historical fact and constitute forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995. These forward-looking statements relate to anticipated future operating
and financial performance measures, including net interest margin, credit
quality, business initiatives, growth opportunities and growth rates, among
other things. Words such as "expects," "anticipates," "believes," "estimates"
and other similar expressions are intended to identify these forward-looking
statements. Such forward-looking statements are subject to certain risks,
uncertainties and assumptions. Should one or more of these risks materialize, or
should any such underlying assumptions prove to be significantly different,
actual results may vary significantly from those anticipated, estimated,

                                        3


projected or expected. These risks could cause actual results to differ
materially from current expectations of management and include the following:

     - The level of nonperforming assets, charge-offs and provision expense can
       be affected by local, state and national economic and market conditions
       as well as management's judgments regarding collectability of loans.

     - Material changes in market interest rates can materially affect many
       aspects of Trustmark's financial condition and results of operations.
       Trustmark is exposed to the potential of losses arising from adverse
       changes in market interest rates and prices which can adversely impact
       the value of financial products, including securities, loans, deposits,
       debt and derivative financial instruments. Factors that may affect the
       market interest rates include local, regional and national economic
       conditions; utilization and effectiveness of market interest rate
       contracts; and the availability of wholesale and retail funding sources
       to Trustmark. Many of these factors are outside Trustmark's control.

     - Increases in prepayment speeds of mortgage loans resulting from a
       declining interest rate environment will have an impact on the fair value
       of the mortgage servicing portfolio which can materially affect
       Trustmark's results of operations.

     - The costs and effects of litigation and of unexpected or adverse outcomes
       in such litigation can materially affect Trustmark's results of
       operations.

     - Competition in loan and deposit pricing, as well as the entry of new
       competitors into our markets through de novo expansion and acquisitions,
       among other means, could have an effect on Trustmark's operations in our
       existing markets.

     - Trustmark is subject to regulation by federal banking agencies and
       authorities and the Securities and Exchange Commission. Changes in
       existing regulations or the adoption of new regulations could make it
       more costly for Trustmark to do business or could force changes in the
       manner Trustmark does business, which could have an impact on Trustmark's
       financial condition or results of operations.

     Although Trustmark believes that the expectations reflected in such
forward-looking statements are reasonable, it can give no assurance that such
expectations will prove to be correct. These statements are representative only
as of the date hereof, and Trustmark does not assume any obligation to update
these forward-looking statements or to update the reasons why actual results
could differ from those projected in the forward-looking statements.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth our historical consolidated ratio of
earnings to fixed charges for the periods indicated.



                                                       FISCAL YEAR ENDED DECEMBER 31,
                                                      --------------------------------

Excluding Interest on Deposits:                       2.89   2.52   2.23   3.06   6.34
Including Interest on Deposits:                       1.67   1.73   1.62   1.82   2.63


     For purposes of computing our ratio of earnings to fixed charges, earnings
consist of net income before extraordinary items plus applicable income taxes,
fixed charges and amortization of capitalized interest. Fixed charges, excluding
interest on deposits, consist of interest expense on federal funds purchased and
securities sold under repurchase agreements, other interest expense (other than
on deposits) and the portion of rentals representative of interest factor. Fixed
charges, including interest on deposits, consist of interest expense on federal
funds purchased and securities sold under repurchase agreements, all other
interest expense and the portion of rentals representative of interest factor.

                       CERTAIN REGULATORY CONSIDERATIONS

     As a bank holding company, Trustmark is subject to the regulation,
supervision and examination of the Federal Reserve Board under the Bank Holding
Company Act of 1956. We are required by the Federal Reserve Board to maintain
certain levels of capital for bank regulatory purposes. We expect that any trust
preferred securities issued hereunder will be treated as Tier 1 capital of
Trustmark for these purposes.

     Because Trustmark is a holding company, dividends and fees from
subsidiaries are Trustmark's principal source of revenues from which to repay
the junior subordinated debt securities. Trustmark's subsidiaries engaged in the
banking, insurance and securities business can only pay dividends if they are in
compliance with applicable United States federal and state regulatory
requirements.

                                USE OF PROCEEDS

     Unless otherwise specified in a prospectus supplement accompanying this
prospectus, the net proceeds from the sale of the offered securities will be
added to our general funds and may be used to:

     - redeem or repurchase outstanding securities;

     - repay outstanding debt;

     - finance acquisitions of companies and other assets; and

     - provide working capital.

     We may conduct concurrent or additional financings at any time. Pending
such uses, we may invest the net proceeds in short term marketable securities.

                              RECENT DEVELOPMENTS

     Early Retirement Program.  In February 2003, Trustmark announced a
voluntary early retirement program for associates age 58 and above with ten or
more years of service. This program was accepted by 116 associates, or 4.75% of
Trustmark's workforce. A one-time after-tax charge of approximately $4.1
million, or $0.07 per share, was recognized in Trustmark's first quarter 2003
earnings in connection with this program.

     First Quarter Earnings.  On April 15, 2003, Trustmark announced earnings
for the three months ended March 31, 2003.

     Net income was $24.5 million for the quarter ended March 31, 2003,
representing basic and diluted earnings per share of $0.41. This represents a
19% decrease in net earnings from the quarter ended March 31, 2002. Earnings
during the quarter included a one-time after-tax charge of approximately $4.1
million in connection with a voluntary early retirement program, described in
Recent Developments -- Early Retirement Program, above.

     Trustmark's performance for the quarter ended March 31, 2003, resulted in a
return on average stockholders' equity of 14.88% and a return on average assets
of 1.40%. The return on average stockholders equity during the quarter ended
March 31, 2002, was 18.22% and the return on average assets during that period
was 1.79%.

     Continued reductions in long-term interest rates reduced the value of
Trustmark's mortgage servicing portfolio. In the quarter ended March 31, 2003,
Trustmark recorded a non-cash after-tax charge of $4.4 million to recognize the
reduction in the value of its mortgage servicing portfolio resulting from
customers taking advantage of the opportunity to refinance their homes at lower
interest rates. Low interest rates also provided Trustmark with the opportunity
to restructure a portion of its fixed income investment portfolio and reduce
exposure to volatile interest rates. During the first quarter of 2003, Trustmark
realized an

                                        5


after-tax net gain of $5.3 million resulting from the sale of fixed income
investment securities as part of this restructuring.

     Stock Repurchase.  During the quarter ended March 31, 2003, Trustmark
repurchased approximately 1.3 million shares of its common stock. At March 31,
2003, Trustmark had authorization to repurchase up to an additional 1.6 million
shares of its common stock. The repurchase program is subject to market
conditions and management discretion.

                          DESCRIPTION OF COMMON STOCK

     The following summary is not complete. You should refer to the applicable
provisions of Trustmark's Articles of Incorporation, as amended, and to the
Mississippi Business Corporation Act for a complete statement of the terms and
rights of the common stock.

     Trustmark has authorized 250 million shares of common stock, no par value.
The common stock is listed on the NASDAQ national market system. Its symbol is
"TRMK."

DIVIDEND RIGHTS

     Holders of outstanding shares of common stock are entitled to receive such
dividends, if any, as may be declared by the Board of Directors of Trustmark, in
its discretion, out of funds legally available therefor.

VOTING RIGHTS

     Holders of common stock are entitled to one vote per share on all matters
to be voted on by the shareholders of Trustmark, including the election of
directors. Holders of common stock have cumulative voting rights with respect to
the election of directors. Under the Mississippi Business Corporation Act, an
affirmative vote of the majority of the shareholders present at a meeting is
sufficient in order to take most shareholder actions. Certain extraordinary
actions, such as mergers and share exchanges, require the affirmative vote of a
majority of the shares entitled to vote.

LIQUIDATION RIGHTS

     In the event of the liquidation of Trustmark, the holders of common stock
are entitled to receive pro rata any assets distributed to shareholders with
respect to their shares, after payment of all debts and payments to holders of
preferred stock of Trustmark, if any.

PREEMPTIVE RIGHTS

     Holders of common stock have no right to subscribe to additional shares of
capital stock that may be issued by Trustmark.

                         DESCRIPTION OF PREFERRED STOCK

     Under Trustmark's Articles of Incorporation, as amended, the Board of
Directors of Trustmark has the authority, without further shareholder action, to
issue a maximum of 20,000,000 shares of preferred stock, in one or more series,
with such terms and for such consideration as may be fixed by the Board of
Directors.

     No preferred shares are currently issued and outstanding.

     The following describes certain general terms and provisions of preferred
stock to which any prospectus supplement may relate. The terms of any series of
preferred stock offered by any prospectus supplement and, if applicable, certain
additional material United States federal income tax consequences relating to
such series of preferred stock, will be specified in the applicable prospectus
supplement.

                                        6


Therefore, the terms of any series of preferred stock may, and likely will,
differ from the terms described below.

     Neither this description nor the description in a prospectus supplement
purports to be complete but each is subject to and qualified in its entirety by
reference to the certificate of designation that will set out the terms of the
applicable series of preferred stock. The certificate of designation will be
filed as an exhibit to, or incorporated by reference in, the registration
statement of which this prospectus forms a part.

GENERAL

     Trustmark's Board of Directors is authorized to set the terms of a series
of preferred stock before issuance, including, but not limited to, (1) the
number of shares to comprise the series; (2) the dividend rate or rates payable
with respect to the shares of the series; (3) any redemption price or prices and
the terms and conditions of the redemption; (4) any voting rights; (5) any
sinking fund provisions for the redemption or purchase of the shares of the
series; (6) any terms and conditions upon which the shares are convertible; and
(7) any other rights, preferences and limitations pertaining to such series.

     The preferred stock will, when issued, be fully paid and nonassessable. The
preferred stock will have no preemptive rights to subscribe for any additional
securities which may be issued by Trustmark.

DIVIDENDS

     As established in the certificate of designation and as described in the
applicable prospectus supplement, the holders of the preferred stock will be
entitled to receive dividends on such preferred stock when and if declared by
the Board of Directors of Trustmark. These dividends will be paid only out of
funds legally available for such payment. Dividends will be payable at such
rates and on such dates as described in the applicable prospectus supplement.
Dividend rates may be fixed or variable or both. If variable, the formula used
for determining the dividend rate for each dividend period will be specified in
the applicable prospectus supplement. Dividends will be payable to the holders
of record as they appear on the stock record books of Trustmark, or, if
applicable, the records of the depositary of any depositary shares, on the
record dates fixed by the Board of Directors of Trustmark. Dividends may be paid
in the form of cash, preferred stock of the same or a different series, or
common stock of Trustmark, in each case as specified in the applicable
prospectus supplement. Dividends on any series of preferred stock may be
cumulative or noncumulative, as specified in the applicable prospectus
supplement. If the Board of Directors of Trustmark fails to declare a dividend
payable on a dividend payment date on any preferred stock for which dividends
are noncumulative, then the holders of that preferred stock will have no right
to receive a dividend in respect of the dividend period relating to that
dividend payment date. In such case, Trustmark will have no obligation to pay
the dividend accrued for that period, whether or not dividends on the preferred
stock are declared or paid on any future dividend payment dates.

     Trustmark will not declare or pay dividends (other than in common stock of
Trustmark or other shares of Trustmark ranking junior to the preferred stock as
to dividends and upon liquidation) on its common stock or on any other of its
shares which rank junior to or on a parity with the preferred stock as to
dividends or upon liquidation, and no common stock or any other shares of
Trustmark ranking junior to or on a parity with the preferred stock as to
dividends or upon liquidation will be redeemed, purchased or otherwise acquired
(or any moneys paid or made available for a sinking fund for the redemption of
any such shares) except by conversion into or exchange for shares of Trustmark
ranking junior to such preferred stock as to dividends and upon liquidation
unless, (1) in the case cumulative preferred stock is then outstanding, full
cumulative dividends have been or are contemporaneously declared and paid or
declared and a sum sufficient for such payment set apart for payment, and (2) in
the case noncumulative preferred stock is then outstanding, dividends for the
then current dividend period on such preferred stock have been or are
contemporaneously declared and paid or declared and a sum sufficient for such
payment set apart for payment.

                                        7


REDEMPTION

     We may issue a series of preferred stock that is redeemable, in whole or in
part, at the option of Trustmark. The terms, if any, on which any series of
preferred stock may be redeemed shall be established in the certificate of
designation for such series of preferred stock and will be summarized in the
prospectus supplement relating to that series.

CONVERSION RIGHTS

     We may issue a series of preferred stock that is convertible into or
exchangeable for our common stock or a different series of preferred stock,
other securities, property or cash, or a combination of any of them. The terms,
if any, on which any series of preferred stock may be convertible or
exchangeable shall be established in the certificate of designation for such
series of preferred stock and will be summarized in the prospectus supplement
relating to that series.

RIGHTS UPON LIQUIDATION

     The rights of the holders of any series of preferred stock in the event of
any voluntary or involuntary liquidation, dissolution or winding up of
Trustmark, if any, will be established in the certificate of designation for
such series and will be summarized in the prospectus supplement relating to that
series. Because Trustmark is a holding company, its rights and the rights of
holders of its securities, including the holders of preferred stock, to
participate in the assets of any Trustmark subsidiary upon the latter's
liquidation or recapitalization will be subject to the prior claims of such
subsidiary's creditors and any preferred stockholders of that subsidiary, except
to the extent Trustmark may itself be a creditor with recognized claims against
such subsidiary or a holder of preferred shares of such subsidiary.

VOTING RIGHTS

     Except as expressly required by applicable law or provided for in the
applicable certificate of designation and prospectus supplement, the holders of
preferred stock will not be entitled to vote. In the event Trustmark issues full
shares of any series of preferred stock, each share will be entitled to one vote
on matters on which holders of the series of the preferred stock are entitled to
vote. However, as more fully described under "Description of Depositary Shares"
below, if Trustmark elects to issue depositary shares representing a fraction of
a share of a series of preferred stock, each depositary share will, in effect,
be entitled to a fraction of a vote, rather than a full vote, per depositary
share. Since each full share of any series of preferred stock of Trustmark will
be entitled to one vote, the voting power of a share of preferred stock, on
matters on which holders of that series and holders of other series of preferred
stock are entitled to vote as a single class, will depend on the relative number
of shares in the series, not the aggregate stated value, liquidation preference
or initial offering price of the shares of such series.

     Under interpretations adopted by the Federal Reserve Board, if the holders
of preferred stock of any series become entitled to vote for the election of
directors, such series may then be deemed a "class of voting securities." A
holder of 25% or more of a class of voting securities, or a holder less than 25%
if it exercises a "controlling influence" over Trustmark, may then be subject to
regulation as a bank holding company in accordance with the Bank Holding Company
Act of 1956. In addition, at the time a class of preferred stock is deemed a
class of voting securities, any other bank holding company may be required to
obtain the prior approval of the Federal Reserve Board to acquire 5% or more of
the series, and any person other than a bank holding company may be required to
obtain the prior approval of the Federal Reserve Board to acquire 10% or more of
the series.

                        DESCRIPTION OF DEPOSITARY SHARES

     The following is a general description of the depositary shares to which
this prospectus and any prospectus supplement may relate. The applicable
prospectus supplement will describe the specific terms of the depositary shares
offered through that prospectus supplement, as well as any general terms
described in

                                        8


this section that will not apply to those depositary shares and, if applicable,
a discussion of certain material United States federal income tax consequences
of owning the depositary shares offered.

     The following description of the depositary shares is subject to the
detailed provisions of the depositary receipts and the deposit agreement
relating to the applicable series of preferred stock, the form of each of which
will be filed as an exhibit to, or incorporated by reference in, the
registration statement of which this prospectus is a part at the time of the
offering of the securities pursuant thereto. Whenever particular provisions of
the depositary receipts or deposit agreement, or terms defined therein, are
referred to, those provisions or definitions are incorporated by reference
herein and such descriptions are qualified in their entirety by such reference.
We urge you to read the depositary receipts and the depositary agreement because
they, and not this description, describe every detail of the terms of the
depositary shares. The summary below of the general terms of the depositary
shares will be supplemented by the more specific terms in a prospectus
supplement.

GENERAL

     Trustmark may, at its option, elect to have shares of its preferred stock
represented by depositary shares. The shares of any series of preferred stock
underlying the depositary shares will be deposited under a separate deposit
agreement that we will enter into with a bank or trust company of our choosing.
The prospectus supplement relating to a series of depositary shares will give
the name and address of the depositary. Subject to the terms of the deposit
agreement, each owner of a depositary share will be entitled to all the rights
and preferences of the preferred stock underlying the depositary share in
proportion to the applicable interest in the preferred stock underlying the
depositary share.

     The depositary shares will be evidenced by depositary receipts issued
pursuant to the deposit agreement. Each depositary share will represent the
applicable interest in a number of shares of a particular series of the
preferred stock described in the applicable prospectus supplement.

     Unless otherwise provided in the applicable prospectus supplement, upon
surrender of depositary shares at the office of the depositary and upon payment
of the charges provided in the deposit agreement, a holder of depositary shares
will be entitled to the number of whole shares of the related series of
preferred stock evidenced by the surrendered depositary shares.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The depositary will distribute all cash dividends or other cash
distributions received in respect of the preferred stock to the record holders
of depositary shares representing the preferred stock in proportion to the
number of the depositary shares owned by the holders on the relevant record
date. The depositary will distribute only that amount which can be distributed
without attributing to any depositary shareholders a fraction of one cent, and
any balance not so distributed will be added to and treated as part of the next
sum received by the depositary for distribution to record depositary
shareholders.

     If there is a distribution other than in cash, the depositary will
distribute property to the entitled record depositary shareholders, unless the
depositary determines that it is not feasible to make that distribution. In that
case the depositary may, with our approval, adopt the method it deems equitable
and practicable for making that distribution, including any sale of property and
the distribution of the net proceeds from this sale to the concerned holders.

     The deposit agreement will also contain provisions relating to the manner
in which any subscription or similar rights we offer to holders of preferred
stock will be made available to holders of depositary shares.

CONVERSION AND EXCHANGE

     If any preferred stock underlying depositary shares is convertible or
exchangeable, each record holder of depositary shares will have the right or
obligation to convert or exchange the depositary shares in the manner provided
in the deposit agreement and described in the applicable prospectus supplement.

                                        9


REDEMPTION BY TRUSTMARK

     If the preferred stock underlying depositary shares is subject to
redemption at our option, the depositary shares will be redeemed from the
redemption proceeds received by the depositary. The redemption price per
depositary share will be equal to the aggregate redemption price payable with
respect to the number of shares of preferred stock underlying the depositary
shares. Whenever we redeem preferred stock from the depositary, the depositary
will redeem as of the same redemption date a proportionate number of depositary
shares representing the shares of preferred stock that we redeemed. If less than
all the depositary shares are to be redeemed, the depositary shares to be
redeemed will be selected by lot or pro rata as we may determine.

     After the date fixed for redemption of the underlying preferred stock, the
depositary shares called for redemption will no longer be deemed to be
outstanding and all rights of the holders of the depositary shares will cease,
except the right to receive the redemption price. Any funds Trustmark deposits
with the depositary for any depositary shares that the holders fail to redeem
will be returned to us after two years from the date the funds are deposited.

VOTING

     Upon receipt of notice of any meeting or action in lieu of any meeting at
which the holders of any shares of preferred stock underlying the depositary
shares are entitled to vote, the depositary will mail the information contained
in the notice to the record holders of the depositary shares relating to the
preferred stock. Each record holder of the depositary shares on the record date,
which will be the same date as the record date for the preferred stock, will be
entitled to instruct the depositary as to the exercise of the voting rights
pertaining to the number of shares of preferred stock underlying the holder's
depositary shares. The depositary will endeavor, insofar as practicable, to vote
the number of shares of preferred stock underlying the depositary shares in
accordance with these instructions, and we will agree to take all action that
the depositary deems necessary to enable the depositary to do so.

AMENDMENT

     The depositary receipt evidencing the depositary shares and any provision
of the deposit agreement may at any time be amended by agreement between
Trustmark and the depositary. However, any amendment that materially and
adversely alters the rights of the existing holders of depositary shares will
not be effective unless the amendment has been approved by the record holders of
at least a majority of the depositary shares then outstanding.

CHARGES OF DEPOSITARY

     We will pay all transfer and other taxes and governmental charges that
arise solely from the existence of the depositary arrangements. We will also pay
charges of the depositary in connection with the initial deposit of the
preferred stock and any exchange or redemption of the preferred stock. Holders
of depositary shares will pay all other transfer and other taxes and
governmental charges, and, in addition, any other charges that are expressly
provided in the deposit agreement to be for their accounts.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The depositary may resign at any time by delivering to us notice of its
election to do so, and we may at any time remove the depositary. Any resignation
or removal will take effect upon the appointment of a successor depositary and
its acceptance of the appointment. We will appoint the successor depositary
within 60 days after delivery of the notice of resignation or removal.

                                        10


TERMINATION OF DEPOSIT AGREEMENT

     The depositary may terminate, or we may direct the depositary to terminate,
the deposit agreement if:

     - we have redeemed or reacquired all outstanding depositary shares relating
       to the deposit agreement; or

     - there has been a final distribution in respect of the preferred stock of
       any series in connection with our liquidation, dissolution or winding up
       and such distribution has been made to the related depositary
       shareholders.

     Upon termination of the deposit agreement, the depositary will discontinue
the transfer of depositary receipts, will suspend the distribution of dividends,
and will not give any further notices (other than notice of the termination) or
perform any further acts under the deposit agreement. However, the depositary
will continue to deliver preferred stock certificates, together with dividends
and distributions and the net proceeds of any sales of property, in exchange for
depositary receipts surrendered. At our request, the depositary will deliver to
us all books, records, certificates evidencing preferred stock, depositary
receipts and other documents relating to the deposit agreement.

MISCELLANEOUS

     We, or at our option the depositary, will make available to the holders of
depositary shares all reports and communications that we are required to furnish
to the holders of preferred stock.

     Neither Trustmark nor the depositary will be liable if the depositary is
prevented or delayed by law or any circumstance beyond its control in performing
its obligations under the deposit agreement. Our obligations and those of the
depositary under the deposit agreement will be limited to performance in good
faith of their respective duties under the deposit agreement. Neither Trustmark
nor the depositary will be obligated to prosecute or defend any legal proceeding
regarding any depositary share or preferred stock unless satisfactory indemnity
has been furnished. Trustmark and the depositary may rely upon written advice of
counsel or accountants. Trustmark and the depositary may also rely upon
information provided to them by persons presenting preferred stock for deposit,
holders of depositary shares or other persons Trustmark or the depositary
believe to be competent. Trustmark and the depositary may also rely upon
documents they believe to be genuine.

                         DESCRIPTION OF DEBT SECURITIES

     The following is a general description of the debt securities to which this
prospectus and any prospectus supplement may relate. The applicable prospectus
supplement will describe the specific terms of the debt securities offered
through that prospectus supplement, as well as any general terms described in
this section that will not apply to those debt securities. A copy of the form of
senior indenture has been filed as an exhibit to the registration statement of
which this prospectus is a part. The indenture will be qualified under the Trust
Indenture Act. Unless otherwise stated, the senior debt securities and the
subordinated debt securities are together referred to as the "debt securities."

GENERAL

     We may issue from time to time one or more series of debt securities under
one or more separate indentures between us and Wilmington Trust Company, as
trustee. The debt securities will be our direct, unsecured obligations. The
senior debt securities will rank equally with all of our other senior debt. The
indentures will not limit the amount of debt securities that we may issue. The
subordination provisions of any subordinated debt securities will be described
in the applicable prospectus supplement.

     The following description of the debt securities is subject to the detailed
provisions of the proposed indenture for the debt securities. A copy of the
indenture will either be filed as an exhibit to the registration statement of
which this prospectus is a part at the time of effectiveness, or will be filed
as an exhibit to, or incorporated by reference in, the registration statement of
which this prospectus is a part at
                                        11


the time of the offering of securities pursuant thereto. We urge you to read the
indenture because the indenture, and not this description, defines your rights
as a holder of debt securities, and will describe in detail the terms of the
debt securities summarized below. The summary below of the general terms of the
debt securities will be supplemented by the more specific terms in a prospectus
supplement. Unless otherwise stated herein or in an applicable prospectus
supplement, the following indenture description will apply to both senior and
subordinated debt securities.

TERMS APPLICABLE TO DEBT SECURITIES

     The prospectus supplement for a particular series of debt securities will
specify the terms of the series of debt securities. These terms will include
some or all of the following:

     - the classification of the offered debt securities as senior or
       subordinated debt securities and, if applicable, the subordination
       provisions that will apply;

     - the specific designation, the aggregate principal amount, the purchase
       price and the authorized denominations of the offered debt securities;

     - the percentage of the principal amount at which the debt securities will
       be issued;

     - the date or dates on which the debt securities will mature;

     - the currency, currencies or currency units in which payments on the debt
       securities will be payable;

     - if other than the remaining outstanding principal amount, the principal
       amount of the debt securities that we will pay upon declaration of
       acceleration of their maturity;

     - the rate or rates at which the debt securities will bear interest, if
       any, or the method of determination of such rate or rates;

     - if applicable, the premium on the debt securities or the method of
       determination of such premium;

     - the date or dates from which the interest, if any, shall accrue, the
       dates on which the interest, if any, will be payable and the method of
       determining holders to whom any of the interest shall be payable;

     - the prices, if any, at which, and the dates at or after which, we may or
       must repay, repurchase or redeem the debt securities;

     - any right or requirement to convert the debt securities into, or exchange
       the debt securities for, shares of our common stock, preferred stock,
       other securities, property or cash, or a combination of any of them;

     - any sinking fund obligation with respect to the debt securities;

     - the exchanges, if any, on which the debt securities may be listed;

     - any addition to or change in the events of default, covenants or
       defeasance provisions in the indenture;

     - if applicable, certain additional material United States federal income
       tax consequences; and

     - any other material terms of the debt securities, consistent with the
       provisions of the indenture.

     The indenture will not contain any provisions that:

     - limit our ability to incur indebtedness; or

     - provide protection in the event we choose to engage in a highly leveraged
       transaction, reorganization, restructuring, merger or similar
       transaction.

     Some of the debt securities may be issued as discounted debt securities,
which are debt securities sold at a substantial discount below their stated
principal amount. The prospectus supplement relating to any

                                        12


discounted series of debt securities will describe any special consequences
applicable to discounted debt securities.

CONVERSION AND EXCHANGE

     We may issue debt securities that are convertible into or exchangeable for
our common stock or preferred stock, other securities, property or cash, or a
combination of any of them. The terms, if any, on which debt securities of any
series will be convertible or exchangeable will be summarized in the prospectus
supplement relating to those debt securities. Those terms may include
provisions, as applicable, for conversion or exchange on a mandatory basis, at
your option, or at our option, in which case the number of shares of our common
stock or preferred stock, or the other securities, property or cash, to be
received upon the conversion or exchange of those debt securities would be
calculated according to the factors and at such time as summarized in the
related prospectus supplement. The prospectus supplement will also summarize
certain of the material United States federal income tax consequences applicable
to any such convertible or exchangeable debt securities.

REOPENING OF ISSUE

     We may, from time to time, reopen an issue of debt securities and issue
additional debt securities with the same terms (including maturity date and
interest rate) as debt securities issued on an earlier date. After such
additional debt securities are issued, they will be fungible with the debt
securities issued on the earlier date to the extent specified in the applicable
prospectus supplement.

RANKING

     The senior debt securities will be unsecured, and will rank equal in right
of payment with all of our existing and future unsecured and unsubordinated
indebtedness. The ranking of the subordinated debt securities will be described
in the applicable prospectus supplement.

COVENANTS

     The indenture shall provide that for so long as any debt securities remain
outstanding under the indenture, or any amount remains unpaid on any of the debt
securities outstanding under the indenture, we will comply with the applicable
terms of the covenants contained in the indenture and, with respect to a series
of debt securities, such other covenants as may be provided in the terms of that
series of debt securities and described in the applicable prospectus supplement.
The prospectus supplement will summarize the covenants contained in the
applicable indenture, which will include some or all of the following:

  PAYMENT OF SECURITIES

     We will duly and punctually pay the principal of and interest on the debt
securities in accordance with the terms of the debt securities and the
indenture.

  MAINTENANCE OF OFFICE OR AGENCY

     We will maintain in the Borough of Manhattan, the City of New York, and
such other locations as may be required or specified in any prospectus
supplement, an office or agency where the debt securities may be paid and
notices and demands to or upon us in respect of the debt securities and the
indentures may be served and an office or agency where debt securities may be
surrendered for registration of transfer or exchange. We will give prompt
written notice to the trustee of the location, and any change in the location,
of each such office or agency. If at any time we shall fail to maintain any
required office or agency or shall fail to furnish the trustee with the address
of any required office or agency, all presentations, surrenders, notices and
demands may be served at the office of the trustee.

                                        13


  FURTHER ASSURANCES

     We will execute and deliver all documents, instruments and agreements, and
do all other acts and things as may be reasonably required, to enable the
trustee to exercise and enforce its rights under an indenture and under the
documents, instruments and agreements required under the indenture and to carry
out the intent of the indenture.

  SEC REPORTS

     We are subject to the informational reporting requirements of Sections 13
and 15(d) under the Securities Exchange Act and, in accordance with those
requirements, we file certain reports and other information with the SEC. See
"Where You Can Find More Information; Documents Incorporated By Reference." If
Sections 13 and 15(d) cease to apply to us, so that we no longer file those
reports or other information with the SEC, we will instead provide copies of the
reports and information that would have been required under Sections 13 and
15(d) of the Securities Exchange Act to the trustee.

  COMPLIANCE CERTIFICATES

     We will file annually with the trustee a certificate describing any
default, which is defined in the indenture as any event which is, or after
notice or passage of time or both would be, an "event of default," in the
performance of any conditions or covenants under the indenture and the status of
any such default. We also must give the trustee written notice within 30 days of
the occurrence of certain defaults under the indenture that could mature into
events of default, as described under the caption "-- Events of Default" below.

MERGER, CONSOLIDATION OR SALE OF ASSETS

     We will not consolidate or combine with or merge with or into or, directly
or indirectly, sell, assign, convey, lease, transfer or otherwise dispose of all
or substantially all of our properties and assets to any person or persons in a
single transaction or series of transactions, unless:

     - we are the surviving entity, or, if we are not the surviving entity, the
       surviving entity is a corporation or limited liability company organized
       and existing under the laws of the United States, any state or the
       District of Columbia;

     - the surviving entity assumes our obligations on each outstanding series
       of debt securities and executes a supplemental indenture which is
       delivered, and is in form and substance reasonably satisfactory, to the
       trustee;

     - immediately after giving effect to the transaction, no default shall have
       occurred and be continuing; and

     - we or the surviving entity deliver to the trustee an opinion of counsel
       stating that the transaction or series of transactions and the
       supplemental indenture, if any, complies with the applicable provisions
       of the indenture.

     If any consolidation or merger or any sale, assignment, conveyance, lease,
transfer or other disposition of all or substantially all of our properties and
assets occurs in accordance with the indenture, the surviving entity (if other
than us) will succeed to, and be substituted for, and may exercise every right
and power we have under the indenture with the same effect as if such surviving
entity had originally been named in the indenture and, except for any lease, we
will be discharged from all obligations and covenants under the indenture and
the debt securities.

                                        14


EVENTS OF DEFAULT

     The prospectus supplement will specify what events constitute events of
default under the indenture with respect to a series of debt securities, which
will include some or all of the following:

     - default for 30 days in payment of any interest installment due and
       payable on any debt securities of such series;

     - default in payment of principal or premium, if any, when due on the debt
       securities of such series;

     - default in the making of any sinking fund payment or analogous obligation
       on the debt securities of such series;

     - material default in our performance of any other covenant or agreement in
       respect of the debt securities of such series;

     - default in the payment when due (whether at maturity, upon redemption or
       acceleration or otherwise) of the principal or premium, if any, of any
       indebtedness for money borrowed by us or any of our significant
       subsidiaries (including any other series of debt securities issued under
       the indenture) in excess of $20,000,000 if such default shall continue
       unremedied or unwaived for more than 30 business days after the
       expiration of any grace period or extension of the time for payment; and

     - events of bankruptcy, insolvency and reorganization specified in the
       indenture.

     An event of default under one series of debt securities may, but will not
necessarily, constitute an event of default under any other series of debt
securities.

     The indenture will provide that if an event of default occurs and is
continuing with respect to any series of debt securities, either the trustee or
the registered holders of at least 25% in aggregate principal amount of that
series of debt securities may declare the principal amount of those debt
securities and any accrued and unpaid interest on those debt securities to be
due and payable immediately. At any time after a declaration of acceleration,
but before a judgment or decree for payment of money has been obtained, if all
events of default with respect to those debt securities have been cured (other
than the nonpayment of principal of such debt securities which has become due
solely by reason of the declaration of acceleration) then the declaration of
acceleration shall be automatically annulled and rescinded.

     The indenture will require that we file annually with the trustee a
certificate describing any default by us in the performance of any conditions or
covenants that has occurred under the indenture and the status of such default.
See "-- Covenants -- Compliance Certificates" above. We must give the trustee
written notice within 30 days of any default under the indenture that could
mature into an event of default described in the last two bullets above.

     The trustee will be entitled under the indenture, subject to the duty of
the trustee during a default to act with the required standard of care, to be
indemnified before proceeding to exercise any right or power under the indenture
at the direction of the registered holders of the debt securities or which
requires the trustee to expend or risk its own funds or otherwise incur any
financial liability. The indenture will also provide that the registered holders
of a majority in principal amount of the outstanding debt securities of any
series issued under the indenture may direct the time, method and place of
conducting any proceeding for any remedy available to the trustee or exercising
any trust or power conferred on the trustee with respect to that series of debt
securities. The trustee, however, may refuse to follow any such direction that
conflicts with law or the indenture, is unduly prejudicial to the rights of
other registered holders of that series of debt securities, or would involve the
trustee in personal liability.

     The indenture will provide that while the trustee generally must mail
notice of a default or an event of default to the registered holders of the debt
securities of any series issued under the indenture within 90 days of the
trustee's knowledge of its occurrence, the trustee may withhold notice of any
default or event of default (except with respect to a default in payment on the
debt securities) if the trustee in good

                                        15


faith determines that the withholding of such notice is in the interest of the
registered holders of that series of debt securities.

MODIFICATION OF THE INDENTURE

     We and the trustee may amend or supplement the indenture if the holders of
a majority in principal amount of the outstanding debt securities of each series
of debt securities affected by the amendment or supplement consent to it, except
that no amendment or supplement may, without the consent of each affected
registered holder of that series:

     - reduce the amount of principal we must repay or change the date of
       maturity;

     - reduce the rate or change the time of payment of interest;

     - change the currency of payment;

     - modify any redemption or repurchase right to the detriment of the holder;

     - reduce the percentage of the aggregate principal amount of debt
       securities needed to consent to an amendment or supplement; or

     - change the provisions of the indenture relating to waiver of past
       defaults, rights of registered holders of the debt securities to receive
       payments or amendments of the indenture that require the consent of
       registered holders of each affected series.

ACTIONS BY HOLDERS

     A holder of debt securities of a series may not pursue any remedy with
respect to the indenture or such series (except a registered holder of debt
securities of such series may bring an action for payment of overdue principal,
premium, if any, or interest on its debt securities), unless:

     - the registered holder has given notice to the trustee of such series of a
       continuing event of default;

     - registered holders of at least 25% in principal amount of that series of
       debt securities have made a written request to the trustee of such series
       to pursue such remedy;

     - such registered holder or holders have offered the trustee of such series
       security or indemnity reasonably satisfactory to the trustee against any
       loss, liability or expense;

     - the trustee of such series has not complied with such request within 60
       days of such request and offer; and

     - the registered holders of a majority in principal amount of that series
       of debt securities have not given the trustee of such series an
       inconsistent direction during that 60-day period.

DEFEASANCE, DISCHARGE AND TERMINATION

  DEFEASANCE AND DISCHARGE

     Unless otherwise provided in the terms of the particular series of debt
securities and described in the applicable prospectus supplement, we may
discharge any and all of our obligations in respect of a series of debt
securities, and the provisions of the indenture will no longer be in effect with
respect to that series of debt securities (except for, among other matters,
certain obligations to register the transfer or exchange of those debt
securities, to replace stolen, lost or mutilated debt securities, to maintain
paying agencies and to hold monies for payment in trust, and the rights of
holders of that series to receive payments of principal, premium, if any, and
interest), on the 123rd day after the date of the deposit with the trustee, in
trust, of money or U.S. Government Obligations (as defined below) that, through
the payment of interest, principal and premium, if any, in accordance with their
terms, will provide money in an amount sufficient to pay the principal, premium,
if any, and interest on that series of debt securities, when due in accordance
with the terms of the indenture and those debt securities. Such a trust may only
be established if, among other things,

                                        16


     - we shall have delivered to the trustee either:

      -- an opinion of outside counsel with respect to certain tax matters as
         described in the indenture, including that registered holders of that
         series will not recognize income, gain or loss for federal income tax
         purposes as a result of the deposit, defeasance and discharge and will
         be subject to federal income tax on the same amount and in the same
         manner and at the same times as would have been the case if such
         deposit, defeasance and discharge had not occurred; or

      -- a ruling of the U.S. Internal Revenue Service to that effect;

     - no default under the indenture with respect to that series shall have
       occurred and be continuing on the date of such deposit or during the
       period ending on the 123rd day after the date of deposit;

     - the deposit shall not result in or constitute a default or result in a
       breach or violation of, or constitute a default under, any other
       agreement or instrument to which we are a party or by which we are bound;
       and

     - we have delivered to the trustee an opinion of counsel stating that such
       conditions have been complied with.

     "U.S. Government Obligations" are defined under the indenture as securities
that are (x) direct obligations of the United States for the payment of which
its full faith and credit is pledged or (y) obligations of a person controlled
or supervised by and acting as an agency or instrumentality of the United
States, the payment of which is unconditionally guaranteed as a full faith and
credit obligation by the United States and which, in either case, are not
callable or redeemable before their maturity.

  TERMINATION OF OBLIGATIONS IN CERTAIN CIRCUMSTANCES

     Unless otherwise provided in the terms of the particular series of debt
securities and described in the applicable prospectus supplement, we may at any
time discharge any and all obligations in respect of a series of debt securities
and the provisions of the indenture will no longer be in effect with respect to
that series of debt securities (except to the extent provided under
"-- Defeasance and Discharge" above) if that series of debt securities matures
within one year of such time and we deposit with the trustee, in trust, money or
U.S. Government Obligations that, through the payment of interest and principal
in accordance with their terms, will provide money in an amount sufficient to
pay the principal of, premium, if any, and accrued interest on that series of
debt securities when due in accordance with the terms of the indenture and that
series of debt securities. Such a trust may only be established if, among other
things:

     - no default under the indenture with respect to that series shall have
       occurred and be continuing on the date of such deposit;

     - the deposit will not result in or constitute a default or result in a
       breach or violation of, or constitute a default under, any other
       agreement or instrument to which we are a party or by which we are bound;
       and

     - we have delivered to the trustee an opinion of counsel stating that such
       conditions have been complied with.

     Pursuant to this provision, we are not required to deliver an opinion of
counsel to the effect that registered holders of that series will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such
deposit and termination, and there is no assurance that registered holders of
that series would not recognize income, gain or loss for U.S. federal income tax
purposes as a result thereof or that they would be subject to U.S. federal
income tax on the same amount and in the same manner and at the same times as
would have been the case if such deposit and termination had not occurred.

                                        17


  DEFEASANCE OF COVENANTS AND RELATED EVENTS OF DEFAULT

     The terms of a series of debt securities may provide for the defeasance of
covenants and related events of default with respect to that series of debt
securities on the 123rd day after the date of the deposit with the trustee, in
trust, of money or U.S. Government Obligations that, through the payment of
interest, principal and premium, if any, in accordance with their terms, will
provide money in an amount sufficient to pay the principal, premium, if any, and
interest on that series of debt securities, when due in accordance with the
terms of the indenture and those debt securities. Such a trust may only be
established if, among other things:

     - we shall have delivered to the trustee an opinion of outside counsel with
       respect to certain tax matters as described in the indenture, including
       that registered holders of that series will not recognize income, gain or
       loss for federal income tax purposes as a result of the deposit,
       defeasance and discharge and will be subject to federal income tax on the
       same amount and in the same manner and at the same times as would have
       been the case if such deposit, defeasance and discharge had not occurred;

     - no default under the indenture with respect to that series shall have
       occurred and be continuing on the date of such deposit or during the
       period ending on the 123rd day after the date of deposit;

     - the deposit shall not result in or constitute a default or result in a
       breach or violation of, or constitute a default under, any other
       agreement or instrument to which we are a party or by which we are bound;
       and

     - we have delivered to the trustee an opinion of counsel stating that such
       conditions have been complied with.

     The prospectus supplement relating to that series of debt securities will
describe the covenants and related events of default with respect to that series
which may be defeased pursuant to this provision.

UNCLAIMED MONEY

     Subject to any applicable abandoned property law, the indenture will
provide that the trustee will pay to us upon request any money held by the
trustee for the payment of principal, premium, if any, or interest that remains
unclaimed for two years. After payment to us, registered holders of debt
securities entitled to such money must look to us for payment as general
creditors.

GOVERNING LAW

     The laws of the state of New York will govern the indenture and each series
of debt securities.

                   DESCRIPTION OF TRUST PREFERRED SECURITIES

     The following is a general description of the trust preferred securities
and related guarantee to which this prospectus and any prospectus supplement may
relate. The applicable prospectus supplement will describe the specific terms of
the trust preferred securities and guarantee offered through that prospectus
supplement, as well as any general terms described in this section that will not
apply to those trust preferred securities.

GENERAL

     Each of the TRMK Trusts may issue from time to time trust preferred
securities representing undivided beneficial interests in the assets of the
trust under its declaration of trust, as it may be amended and restated from
time to time. Such trust preferred securities will be unconditionally and
irrevocably guaranteed, to the extent funds are available, by Trustmark, as
described in "Description Of Guarantees" and "Relationship Among The Trust
Preferred Securities, The Corresponding Junior Subordinated Debt Securities And
The Guarantee," below. Each trust will use the proceeds from the sale of its
trust preferred

                                        18


securities to purchase debt securities from Trustmark, which may be distributed
to holders of the trust preferred and trust common securities either upon
dissolution of the trust or upon the occurrence of events that will be described
in the applicable prospectus supplement. When a trust issues its trust preferred
securities, you and the other holders of the trust preferred securities will own
all of the issued and outstanding trust preferred securities of the trust.
Trustmark will acquire all of the issued and outstanding trust common securities
of each trust, representing an undivided beneficial interest in the assets of
the trust of at least 3% of the total capital of such trust.

     The following description of trust preferred securities and related
guarantees is subject to the detailed provisions of the applicable declaration
of trust (as it may be amended and restated from time to time) and guarantee. A
copy of the applicable declaration of trust has been filed as an exhibit to the
registration statement of which this prospectus is a part and the form of
guarantee will be filed with the applicable prospectus supplement. Whenever
particular provisions of a declaration of trust or guarantee, or terms defined
therein, are referred to, those provisions or definitions are incorporated by
reference herein and such descriptions are qualified in their entirety by such
reference. We urge you to read the declaration of trust and the guarantee
because they, and not this description, describe every detail of the terms of
the trust preferred securities and related guarantees.

TERMS APPLICABLE TO THE TRUST PREFERRED SECURITIES

     The prospectus supplement relating to the issuance of trust preferred
securities by a trust will include specific terms relating to the offering.
These terms will include some or all of the following:

     - the designation of the trust preferred securities;

     - the number of trust preferred securities issued by the trust;

     - the annual distribution rate and any conditions upon which distributions
       are payable, the distribution payment dates, the record dates for
       distribution payments and the additional amounts, if any, that may be
       payable with respect to the trust preferred securities;

     - whether distributions will be cumulative and compounding and, if so, the
       dates from which distributions will be cumulative or compounded;

     - the amounts that will be paid out of the assets of the trust, after the
       satisfaction of liabilities to creditors of the trust, to the holders of
       trust preferred securities upon dissolution;

     - any repurchase, redemption or exchange provisions;

     - any preference or subordination rights upon a default or liquidation of
       the trust;

     - any voting rights of the trust preferred securities in addition to those
       required by law;

     - if applicable, a discussion of certain material United States federal
       income tax consequences of owning the trust preferred securities;

     - any rights to defer distributions on the trust preferred securities by
       extending the interest payment period on the debt securities; and

     - any other relevant terms, rights, preferences, privileges, limitations or
       restrictions of the trust preferred securities.

     The administrative trustees, on behalf of the trust and pursuant to the
declaration of trust, will issue one class of trust preferred securities and one
class of trust common securities. The trust securities will represent undivided
beneficial ownership interests in the assets of the trust.

     Except as described in the applicable prospectus supplement, the trust
preferred securities will rank equally, and payments will be made thereon
proportionately, with the trust common securities. The property trustee of the
trust will hold legal title to the debt securities in trust for the benefit of
the holders of the trust securities. Trustmark will execute a guarantee
agreement for the benefit of the holders of the

                                        19


trust preferred securities. The guarantee will not guarantee the payment of
distributions (as defined below) or any amounts payable on redemption or
liquidation of the trust preferred securities when the trust does not have funds
on hand available to make such payments.

INFORMATION CONCERNING THE TRUSTEE

     The trustee of each TRMK Trust undertakes to perform such duties and only
such duties as are specifically set forth in the declaration of trust. Trustmark
may appoint or remove any trustee of any TRMK Trust at any time, with or without
cause, subject to the requirements of the Delaware Statutory Trust Act.

OBLIGATIONS OF TRUSTMARK WITH RESPECT TO THE TRMK TRUSTS

     Trustmark, as the holder of the trust common securities, will be
responsible for filing on behalf of each TRMK Trust: all prospectus supplements
and other filings with the SEC regarding the trust preferred securities; a
listing application and all other applications, statements, certificates,
agreements and other instruments necessary for the listing of the trust
preferred securities on the New York Stock Exchange or any other exchange or the
quotation of the trust preferred securities on any securities association; and
any other applications, statements, certificates, agreements or other
instruments as may be required by federal, state or local law.

     Trustmark, as holder of the trust common securities, will pay all debts and
obligations and all costs and expenses of each TRMK Trust, including, but not
limited to, all costs and expenses relating to the organization of each TRMK
Trust, the fees and expenses of the trustees and all costs and expenses relating
to the operation of such TRMK Trust, and to pay any and all taxes, duties,
assessments or other governmental charges of whatever nature imposed on each
TRMK Trust by the United States or any other taxing authority. Trustmark will
indemnify the trustees of each TRMK Trust for any and all damages, liabilities
and other costs (including reasonable attorneys' fees) to the extent that any
such damages, liabilities and costs arise out of or are imposed with respect to
the performance of the obligations set forth in the declaration of trust, the
creation or operation of the applicable TRMK Trust or the issuance of the trust
preferred securities.

GOVERNING LAW

     The laws of the state of Delaware will govern each TRMK Trust and the trust
preferred securities.

               DESCRIPTION OF JUNIOR SUBORDINATED DEBT SECURITIES

     The following is a general description of the junior subordinated debt
securities to which this prospectus and any prospectus supplement may relate.
The applicable prospectus supplement will describe the specific terms of the
junior subordinated debt securities offered through that prospectus supplement,
as well as any general terms described in this section that will not apply to
those junior subordinated debt securities.

     The following description of the junior subordinated debt securities is
subject to the detailed provisions of the proposed indenture for the junior
subordinated debt securities. A copy of the form of indenture has been filed as
an exhibit to the registration statement of which this prospectus is a part. The
indenture will be qualified under the Trust Indenture Act. Whenever particular
provisions of the indenture or terms defined in the indenture are referred to,
those provisions or definitions are incorporated by reference herein and such
descriptions are qualified in their entirety by such reference. We urge you to
read the form of indenture because the indenture, and not this description,
defines your rights as a holder of junior subordinated debt securities, and will
describe in detail the terms of the junior subordinated debt securities
summarized below. The summary below of the general terms of the junior
subordinated debt securities will be supplemented by the more specific terms in
a prospectus supplement. Unless otherwise

                                        20


stated herein or in an applicable prospectus supplement, the following indenture
description will apply to both senior and subordinated debt securities.

TERMS APPLICABLE TO DEBT SECURITIES

     The prospectus supplement for a particular series of junior subordinated
debt securities will specify the terms of the series of junior subordinated debt
securities. These terms will include some or all of the following:

     - the classification of the offered junior subordinated debt securities and
       the subordination provisions that will apply;

     - the specific designation, the aggregate principal amount, the purchase
       price and the authorized denominations of the offered junior subordinated
       debt securities;

     - the percentage of the principal amount at which the junior subordinated
       debt securities will be issued;

     - the date or dates on which the junior subordinated debt securities will
       mature;

     - the currency, currencies or currency units in which payments on the
       junior subordinated debt securities will be payable;

     - if other than the remaining outstanding principal amount, the principal
       amount of the junior subordinated debt securities that we will pay upon
       declaration of acceleration of their maturity;

     - the rate or rates at which the junior subordinated debt securities will
       bear interest, if any, or the method of determination of such rate or
       rates;

     - if applicable, the premium on the junior subordinated debt securities or
       the method of determination of such premium;

     - the date or dates from which the interest, if any, shall accrue, the
       dates on which the interest, if any, will be payable and the method of
       determining holders to whom any of the interest shall be payable;

     - the prices, if any, at which, and the dates at or after which, we may or
       must repay, repurchase or redeem the junior subordinated debt securities;

     - any right or requirement to convert the junior subordinated debt
       securities into, or exchange the debt securities for, shares of our
       common stock, preferred stock, other securities, property or cash, or a
       combination of any of them;

     - any sinking fund obligation with respect to the junior subordinated debt
       securities;

     - the exchanges, if any, on which the debt securities may be listed;

     - any addition to or change in the events of default, covenants or
       defeasance provisions in the indenture;

     - if applicable, certain additional material United States federal income
       tax consequences; and

     - any other material terms of the debt securities, consistent with the
       provisions of the indenture.

     The indenture will not contain any provisions that:

     - limit our ability to incur indebtedness; or

     - provide protection in the event we choose to engage in a highly leveraged
       transaction, reorganization, restructuring, merger or similar
       transaction.

     Unless otherwise specified in the prospectus supplement, we will compute
interest payments on the basis of a 360-day year consisting of twelve 30-day
months.

                                        21


     Some of the junior subordinated debt securities may be issued as discounted
securities, which are debt securities sold at a substantial discount below their
stated principal amount. The prospectus supplement relating to any discounted
series of junior subordinated debt securities will describe any special
consequences applicable to discounted debt securities.

REOPENING OF ISSUE

     We may, from time to time, reopen an issue of junior subordinated debt
securities and issue additional junior subordinated debt securities with the
same terms (including maturity date and interest rate) as junior subordinated
debt securities issued on an earlier date. After such additional junior
subordinated debt securities are issued, they will be fungible with the junior
subordinated debt securities issued on the earlier date to the extent specified
in the applicable prospectus supplement.

RANKING

     The ranking of the junior subordinated debt securities will be described in
the applicable prospectus supplement.

COVENANTS

     The indenture shall provide that for so long as any junior subordinated
debt securities remain outstanding under the indenture, or any amount remains
unpaid on any of the junior subordinated debt securities outstanding under the
indenture, we will comply with the applicable terms of the covenants contained
in the indenture and, with respect to a series of debt securities, such other
covenants as may be provided in the terms of that series of junior subordinated
debt securities and described in the applicable prospectus supplement. The
indenture shall contain the following covenants:

  PAYMENT OF SECURITIES

     We will duly and punctually pay the principal of and interest on the junior
subordinated debt securities in accordance with the terms of the debt securities
and the indenture.

  MAINTENANCE OF OFFICE OR AGENCY

     We will maintain in the Borough of Manhattan, the City of New York, and
such other locations as may be required or specified in any prospectus
supplement, an office or agency where the junior subordinated debt securities
may be paid and notices and demands to or upon us in respect of the junior
subordinated debt securities and the indentures may be served and an office or
agency where junior subordinated debt securities may be surrendered for
registration of transfer or exchange. We will give prompt written notice to the
trustee of the location, and any change in the location, of each such office or
agency. If at any time we shall fail to maintain any required office or agency
or shall fail to furnish the trustee with the address of any required office or
agency, all presentations, surrenders, notices and demands may be served at the
office of the trustee.

  FURTHER ASSURANCES

     We will execute and deliver all documents, instruments and agreements, and
do all other acts and things as may be reasonably required, to enable the
trustee to exercise and enforce its rights under an indenture and under the
documents, instruments and agreements required under the indenture and to carry
out the intent of the indenture.

  SEC REPORTS

     We are subject to the informational reporting requirements of Sections 13
and 15(d) under the Securities Exchange Act and, in accordance with those
requirements, we file certain reports and other information with the SEC. See
"Where You Can Find More Information; Documents Incorporated By

                                        22


Reference." If Sections 13 and 15(d) cease to apply to us, so that we no longer
file those reports or other information with the SEC, we will instead provide
copies of the reports and information that would have been required under
Sections 13 and 15(d) of the Securities Exchange Act to the trustee.

  COMPLIANCE CERTIFICATES

     We will file annually with the trustee a certificate describing any
default, which is defined in the indenture as any event which is, or after
notice or passage of time or both would be, an "event of default," in the
performance of any conditions or covenants under the indenture and the status of
any such default. We also must give the trustee written notice within 30 days of
the occurrence of certain defaults under the indenture that could mature into
events of default, as described under the caption "-- Events of Default" below.

MERGER, CONSOLIDATION OR SALE OF ASSETS

     We will not consolidate or combine with or merge with or into or, directly
or indirectly, sell, assign, convey, lease, transfer or otherwise dispose of all
or substantially all of our properties and assets to any person or persons in a
single transaction or series of transactions, unless:

     - we are the surviving entity, or, if we are not the surviving entity, the
       surviving entity is a corporation or limited liability company organized
       and existing under the laws of the United States, any state or the
       District of Columbia;

     - the surviving entity assumes our obligations on each outstanding series
       of junior subordinated debt securities and executes a supplemental
       indenture which is delivered, and is in form and substance reasonably
       satisfactory, to the trustee;

     - immediately after giving effect to the transaction, no default shall have
       occurred and be continuing; and

     - we or the surviving entity deliver to the trustee an opinion of counsel
       stating that the transaction or series of transactions and the
       supplemental indenture, if any, complies with the applicable provisions
       of the indenture.

     If any consolidation or merger or any sale, assignment, conveyance, lease,
transfer or other disposition of all or substantially all of our properties and
assets occurs in accordance with the indenture, the surviving entity (if other
than us) will succeed to, and be substituted for, and may exercise every right
and power we have under the indenture with the same effect as if such surviving
entity had originally been named in the indenture and, except for any lease, we
will be discharged from all obligations and covenants under the indenture and
the debt securities.

EVENTS OF DEFAULT

     The prospectus supplement will specify what events constitute events of
default under the indenture with respect to a series of junior subordinated debt
securities, which will include some or all of the following:

     - default for 30 days in payment of any interest installment due and
       payable on any junior subordinated debt securities of such series;

     - default in payment of principal or premium, if any, when due on the
       junior subordinated debt securities of such series;

     - default in the making of any sinking fund payment or analogous obligation
       on the junior subordinated debt securities of such series;

     - material default in our performance of any other covenant or agreement in
       respect of the junior subordinated debt securities of such series for 60
       days after written notice has been given either to

                                        23


       us by the trustee, or to us and the trustee by the holders of at least
       25% in aggregate principal amount of the junior subordinated debt
       securities of such series then outstanding;

     - default in the payment when due (whether at maturity, upon redemption or
       acceleration or otherwise) of the principal or premium, if any, of any
       indebtedness for money borrowed by us or any of our significant
       subsidiaries (including any other series of debt securities issued under
       the indenture) in excess of $20,000,000 if such default shall continue
       unremedied or unwaived for more than 30 business days after the
       expiration of any grace period or extension of the time for payment; and

     - events of bankruptcy, insolvency and reorganization specified in the
       indenture.

     An event of default under one series of junior subordinated debt securities
may, but will not necessarily, constitute an event of default under any other
series of debt securities.

     The indenture will provide that if an event of default occurs and is
continuing with respect to any series of junior subordinated debt securities,
either the trustee or the registered holders of at least 25% in aggregate
principal amount of that series of junior subordinated debt securities may
declare the principal amount of those junior subordinated debt securities and
any accrued and unpaid interest on those junior subordinated debt securities to
be due and payable immediately. At any time after a declaration of acceleration,
but before a judgment or decree for payment of money has been obtained, if all
events of default with respect to those junior subordinated debt securities have
been cured (other than the nonpayment of principal of such debt securities which
has become due solely by reason of the declaration of acceleration) then the
declaration of acceleration shall be automatically annulled and rescinded.

     The indenture will require that we file annually with the trustee a
certificate describing any default by us in the performance of any conditions or
covenants that has occurred under the indenture and the status of such default.
See "-- Covenants -- Compliance Certificates" above. We must give the trustee
written notice within 30 days of any default under the indenture that could
mature into an event of default described in the last two bullets above.

     The trustee will be entitled under the indenture, subject to the duty of
the trustee during a default to act with the required standard of care, to be
indemnified before proceeding to exercise any right or power under the indenture
at the direction of the registered holders of the junior subordinated debt
securities or which requires the trustee to expend or risk its own funds or
otherwise incur any financial liability. The indenture will also provide that
the registered holders of a majority in principal amount of the outstanding
junior subordinated debt securities of any series issued under the indenture may
direct the time, method and place of conducting any proceeding for any remedy
available to the trustee or exercising any trust or power conferred on the
trustee with respect to that series of junior subordinated debt securities. The
trustee, however, may refuse to follow any such direction that conflicts with
law or the indenture, is unduly prejudicial to the rights of other registered
holders of that series junior subordinated debt securities, or would involve the
trustee in personal liability.

     The indenture will provide that while the trustee generally must mail
notice of a default or an event of default to the registered holders of the
junior subordinated debt securities of any series issued under the indenture
within 90 days of the trustee's knowledge of its occurrence, the trustee may
withhold notice of any default or event of default (except with respect to a
default in payment on the debt securities) if the trustee in good faith
determines that the withholding of such notice is in the interest of the
registered holders of that series of junior subordinated debt securities.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF TRUST PREFERRED SECURITIES

     If an event of default with respect to a series of corresponding junior
subordinated debt securities has occurred and is continuing and such event is
attributable to the failure of Trustmark to pay interest or principal on such
corresponding junior subordinated debt securities on the date such interest or
principal is due and payable, a holder of the related trust preferred securities
may institute a suit directly against Trustmark for enforcement of payment to
such holder of principal of (and premium, if any) and interest on such
corresponding junior subordinated debt securities having a principal amount
equal to the aggregate

                                        24


liquidation amount of the related trust preferred securities of such holder.
Trustmark may not amend the indenture related to the corresponding junior
subordinated debt securities to remove the foregoing right to bring a direct
action without the prior consent of the holders of all of the related trust
preferred securities outstanding until the principal (and premium, if any) of
the corresponding junior subordinated debt securities and all accrued unpaid
interest thereon have been paid in full.

     The holders of such related trust preferred securities will not be able to
exercise directly any remedies other than those set forth in the preceding
paragraph available to the holders of the junior subordinated debt securities
unless there shall have been an event of default under the applicable trust
agreement.

MODIFICATION OF THE INDENTURE

     We and the trustee may amend or supplement the indenture if the holders of
a majority in principal amount of the outstanding junior subordinated debt
securities of each series of junior subordinated debt securities affected by the
amendment or supplement consent to it, except that no amendment or supplement
may, without the consent of each affected registered holder of that series:

     - reduce the amount of principal we must repay or change the date of
       maturity;

     - reduce the rate or change the time of payment of interest;

     - change the currency of payment;

     - modify any redemption or repurchase right to the detriment of the holder;

     - reduce the percentage of the aggregate principal amount of junior
       subordinated debt securities needed to consent to an amendment or
       supplement; or

     - change the provisions of the indenture relating to waiver of past
       defaults, rights of registered holders of the debt securities to receive
       payments or amendments of the indenture that require the consent of
       registered holders of each affected series.

ACTIONS BY HOLDERS

     A holder of junior subordinated debt securities of a series may not pursue
any remedy with respect to the indenture or such series (except a registered
holder of junior subordinated debt securities of such series may bring an action
for payment of overdue principal, premium, if any, or interest on its debt
securities), unless:

     - the registered holder has given notice to the trustee of such series of a
       continuing event of default;

     - registered holders of at least 25% in principal amount of that series of
       junior subordinated debt securities have made a written request to the
       trustee of such series to pursue such remedy;

     - such registered holder or holders have offered the trustee of such series
       security or indemnity reasonably satisfactory to the trustee against any
       loss, liability or expense;

     - the trustee of such series has not complied with such request within 60
       days of such request and offer; and

     - the registered holders of a majority in principal amount of that series
       of junior subordinated debt securities have not given the trustee of such
       series an inconsistent direction during that 60-day period.

DEFEASANCE, DISCHARGE AND TERMINATION

 DEFEASANCE AND DISCHARGE

     Unless otherwise provided in the terms of the particular series of junior
subordinated debt securities and described in the applicable prospectus
supplement, we may discharge any and all of our obligations in respect of a
series of junior subordinated debt securities, and the provisions of the
indenture will no longer
                                        25


be in effect with respect to that series of junior subordinated debt securities
(except for, among other matters, certain obligations to register the transfer
or exchange of those junior subordinated debt securities, to replace stolen,
lost or mutilated junior subordinated debt securities, to maintain paying
agencies and to hold monies for payment in trust, and the rights of holders of
that series to receive payments of principal, premium, if any, and interest), on
the 123rd day after the date of the deposit with the trustee, in trust, of money
or U.S. Government Obligations (as defined below) that, through the payment of
interest, principal and premium, if any, in accordance with their terms, will
provide money in an amount sufficient to pay the principal, premium, if any, and
interest on that series of junior subordinated debt securities, when due in
accordance with the terms of the indenture and those junior subordinated debt
securities. Such a trust may only be established if, among other things,

     - we shall have delivered to the trustee either:

      - an opinion of outside counsel with respect to certain tax matters as
        described in the indenture, including that registered holders of that
        series will not recognize income, gain or loss for federal income tax
        purposes as a result of the deposit, defeasance and discharge and will
        be subject to federal income tax on the same amount and in the same
        manner and at the same times as would have been the case if such
        deposit, defeasance and discharge had not occurred; or

      - a ruling of the U.S. Internal Revenue Service to that effect;

     - no default under the indenture with respect to that series shall have
       occurred and be continuing on the date of such deposit or during the
       period ending on the 123rd day after the date of deposit;

     - the deposit shall not result in or constitute a default or result in a
       breach or violation of, or constitute a default under, any other
       agreement or instrument to which we are a party or by which we are bound;
       and

     - we have delivered to the trustee an opinion of counsel stating that such
       conditions have been complied with.

     "U.S. Government Obligations" are defined under the indenture as securities
that are (x) direct obligations of the United States for the payment of which
its full faith and credit is pledged or (y) obligations of a person controlled
or supervised by and acting as an agency or instrumentality of the United
States, the payment of which is unconditionally guaranteed as a full faith and
credit obligation by the United States and which, in either case, are not
callable or redeemable before their maturity.

 TERMINATION OF OBLIGATIONS IN CERTAIN CIRCUMSTANCES

     Unless otherwise provided in the terms of the particular series of junior
subordinated debt securities and described in the applicable prospectus
supplement, we may at any time discharge any and all obligations in respect of a
series of junior subordinated debt securities and the provisions of the
indenture will no longer be in effect with respect to that series of junior
subordinated debt securities (except to the extent provided under "-- Defeasance
and Discharge" above) if that series of junior subordinated debt securities
matures within one year of such time and we deposit with the trustee, in trust,
money or U.S. Government Obligations that, through the payment of interest and
principal in accordance with their terms, will provide money in an amount
sufficient to pay the principal of, premium, if any, and accrued interest on
that series of junior subordinated debt securities when due in accordance with
the terms of the indenture and that series of junior subordinated debt
securities. Such a trust may only be established if, among other things:

     - no default under the indenture with respect to that series shall have
       occurred and be continuing on the date of such deposit;

     - the deposit will not result in or constitute a default or result in a
       breach or violation of, or constitute a default under, any other
       agreement or instrument to which we are a party or by which we are bound;
       and

                                        26


     - we have delivered to the trustee an opinion of counsel stating that such
       conditions have been complied with.

     Pursuant to this provision, we are not required to deliver an opinion of
counsel to the effect that registered holders of that series will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such
deposit and termination, and there is no assurance that registered holders of
that series would not recognize income, gain or loss for U.S. federal income tax
purposes as a result thereof or that they would be subject to U.S. federal
income tax on the same amount and in the same manner and at the same times as
would have been the case if such deposit and termination had not occurred.

 DEFEASANCE OF COVENANTS AND RELATED EVENTS OF DEFAULT

     The terms of a series of junior subordinated debt securities may provide
for the defeasance of covenants and related events of default with respect to
that series of junior subordinated debt securities on the 123rd day after the
date of the deposit with the trustee, in trust, of money or U.S. Government
Obligations that, through the payment of interest, principal and premium, if
any, in accordance with their terms, will provide money in an amount sufficient
to pay the principal, premium, if any, and interest on that series of junior
subordinated debt securities, when due in accordance with the terms of the
indenture and those junior subordinated debt securities. Such a trust may only
be established if, among other things:

     - we shall have delivered to the trustee an opinion of outside counsel with
       respect to certain tax matters as described in the indenture, including
       that registered holders of that series will not recognize income, gain or
       loss for federal income tax purposes as a result of the deposit,
       defeasance and discharge and will be subject to federal income tax on the
       same amount and in the same manner and at the same times as would have
       been the case if such deposit, defeasance and discharge had not occurred;

     - no default under the indenture with respect to that series shall have
       occurred and be continuing on the date of such deposit or during the
       period ending on the 123rd day after the date of deposit;

     - the deposit shall not result in or constitute a default or result in a
       breach or violation of, or constitute a default under, any other
       agreement or instrument to which we are a party or by which we are bound;
       and

     - we have delivered to the trustee an opinion of counsel stating that such
       conditions have been complied with.

     The prospectus supplement relating to that series of junior subordinated
debt securities will describe the covenants and related events of default with
respect to that series which may be defeased pursuant to this provision.

UNCLAIMED MONEY

     Subject to any applicable abandoned property law, the indenture will
provide that the trustee will pay to us upon request any money held by the
trustee for the payment of principal, premium, if any, or interest that remains
unclaimed for two years. After payment to us, registered holders of junior
subordinated debt securities entitled to such money must look to us for payment
as general creditors.

CONCERNING THE TRUSTEE AND PAYING AGENT

     Wilmington Trust Company will initially act as trustee and paying agent for
the junior subordinated debt securities.

     We will describe in the prospectus supplement any material business and
other relationships (including additional trusteeships) other than ordinary
banking relationships and the trusteeship under the indenture, between us and
any of our affiliates, on the one hand, and each trustee and paying agent under
the indenture, on the other hand.
                                        27


     The holders of a majority in principal amount of the outstanding junior
subordinated debt securities of a series will have the right to direct the time,
method and place of conducting any proceeding for exercising any remedy
available to the trustee with respect to that series, subject to exceptions
described in the indenture. If an event of default occurs and is not cured, the
trustee will be required, in the exercise of its power, to use the degree of
care of a prudent person in the conduct of his or her own affairs. Subject to
such provisions, the trustee will be under no obligation to exercise any of its
rights or powers under the indenture at the request of any holder of junior
subordinated debt securities, unless such holder shall have offered to the
trustee security and indemnity satisfactory to the trustee against any loss,
liability or expense and then only to the extent required by the terms of the
indenture.

SUBORDINATION

     Trustmark covenants and agrees, and each holder of a junior subordinated
debt security, by its acceptance thereof, likewise covenants and agrees, that
the payment of the principal of (and premium, if any) and interest on each and
all of the junior subordinated debt securities are hereby expressly made
subordinate and junior in right of payment to the prior payment in full of all
amounts then due and payable in respect of all senior debt.

     In the event of:

     - any receivership, insolvency, liquidation, bankruptcy, reorganization,
       arrangement, adjustment, composition or other judicial proceeding
       relative to Trustmark, its creditors or its property,

     - any proceeding for the liquidation, dissolution, or other winding up of
       Trustmark, voluntary or involuntary, whether or not involving insolvency
       or bankruptcy proceedings,

     - any assignment by Trustmark for the benefit of creditors or

     - any other marshaling of the assets of Trustmark (each such event, if any,
       herein sometimes referred to as a "Proceeding"),

then the holders of senior debt shall be entitled to receive payment in full of
principal of (and premium, if any) and interest, if any, on such senior debt, or
provision shall be made for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of senior debt, before the
holders of the junior subordinated debt securities are entitled to receive or
retain any payment or distribution of any kind or character, whether in cash,
property or securities (including any payment or distribution which may be
payable or deliverable by reason of the payment of any other debt of Trustmark
(including any series of the junior subordinated debt securities) subordinated
to the payment of the junior subordinated debt securities, such payment or
distribution being hereinafter referred to as a "Junior Subordinated Payment"),
on account of principal of (or premium, if any) or interest on the junior
subordinated debt securities or on account of the purchase or other acquisition
of junior subordinated debt securities by Trustmark or any subsidiary and to
that end the holders of senior debt shall be entitled to receive, for
application to the payment thereof, any payment or distribution of any kind or
character, whether in cash, property or securities, including any Junior
Subordinated Payment, which may be payable or deliverable in respect of the
junior subordinated debt securities in any such Proceeding; provided, however,
that holders of senior debt shall not be entitled to receive payment of any such
amounts to the extent that such holders would be required by the subordination
provisions of such senior debt to pay such amounts over to the obligees on trade
accounts payable or other liabilities arising in the ordinary course of
business. In the event that, notwithstanding the foregoing provisions, the
trustee of the junior subordinated debt securities or the holder of any junior
subordinated debt securities shall have received any payment or distribution of
assets of Trustmark of any kind or character, whether in cash, property or
securities, including any Junior Subordinated Payment, before all senior debt is
paid in full or payment thereof is provided for in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of senior debt, then and in
such event such payment or distribution shall be paid over or delivered
forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other person making payment or distribution of
assets of Trustmark for application to the payment of all senior debt remaining
unpaid, to the extent

                                        28


necessary to pay all senior debt in full, after giving effect to any concurrent
payment or distribution to or for the holders of senior debt.

TRUST EXPENSES

     Trustmark, as holder of the trust common securities, will pay all debts and
obligations and all costs and expenses of each TRMK Trust, including, but not
limited to, all costs and expenses relating to the organization of each TRMK
Trust, the fees and expenses of the trustees and all costs and expenses relating
to the operation of such TRMK Trust, and to pay any and all taxes, duties,
assessments or other governmental charges of whatever nature imposed on each
TRMK Trust by the United States or any other taxing authority.

INFORMATION CONCERNING THE TRUSTEE

     The trustee of each TRMK Trust undertakes to perform such duties and only
such duties as are specifically set forth in the indenture related to the junior
subordinated debt securities, and no implied covenants or obligations shall be
read into the indenture against the trustee. The trustee shall be under no
obligation to exercise any of the rights or powers vested in it by the indenture
related to the junior subordinated debt securities at the request or direction
of any of the holders of junior subordinated debt securities pursuant to the
indenture, unless such holders shall have offered to the trustee security or
indemnity satisfactory to it against the costs, expenses and liabilities which
might be incurred by it in compliance with such request or direction.

GOVERNING LAW

     The laws of the state of New York will govern the indenture and each series
of junior subordinated debt securities.

                           DESCRIPTION OF GUARANTEES

     A guarantee will be executed and delivered by Trustmark at the same time
each TRMK Trust issues its trust preferred securities. Each guarantee is for the
benefit of the holders from time to time of such trust preferred securities.
Wilmington Trust Company, as guarantee trustee, will hold the guarantee for the
benefit of the holders of the related TRMK Trust's trust preferred securities
for the purposes of compliance with the Trust Indenture Act. Each guarantee will
be qualified as an indenture under the Trust Indenture Act.

     This summary of certain terms and provisions of the guarantees is not
complete. For a complete description, you should read each guarantee. The form
of guarantee will be filed with the applicable prospectus supplement.

     References to trust preferred securities include the trust preferred issued
by the related TRMK Trust to which a guarantee relates.

     Trustmark will irrevocably and unconditionally guarantee payments on the
trust preferred securities of each of the TRMK Trusts to the extent funds are
available, as described in this section. The guarantee covers the following
payments:

     - periodic cash distributions on the trust preferred securities out of
       funds held by the property trustee of the TRMK Trust;

     - payments on dissolution of the TRMK Trust; and

     - payments on redemption of trust preferred securities of the TRMK Trust.

     Selected provisions of the guarantee are summarized below. This summary is
not complete. For a complete description, we encourage you to read the
guarantee, the form of which will be filed as an exhibit to the applicable
prospectus supplement.
                                        29


     Trustmark will irrevocably and unconditionally agree to pay you in full the
following amounts to the extent not paid by a TRMK Trust:

     - any accumulated and unpaid distributions and any additional amounts with
       respect to the trust preferred securities and any redemption price for
       trust preferred securities called for redemption by the TRMK Trust, but
       only to the extent that the TRMK Trust has sufficient funds for the
       payment of such distributions or such additional amounts;

     - payments upon the dissolution of the TRMK Trust equal to the lesser of:
       (a) the liquidation amount plus all accumulated and unpaid distributions
       and additional amounts on the trust preferred securities to the extent
       the TRMK Trust has funds legally available for those payments; and (b)
       the amount of assets of the TRMK Trust remaining legally available for
       distribution to the holders of trust preferred securities in liquidation
       of the TRMK Trust.

     Trustmark will not be required to make these liquidation payments if:

     - the TRMK Trust distributes the debt securities to the holders of trust
       preferred securities in exchange for its trust preferred securities; or

     - the TRMK Trust redeems its trust preferred securities in full upon the
       maturity or redemption of the debt securities.

     Trustmark may satisfy its obligation to make a guarantee payment either by
making payment directly to the holders of trust preferred securities or to the
guarantee trustee for remittance to the holders or by causing the applicable
TRMK Trust to make the payment to the holders.

     Each guarantee is a guarantee from the time of issuance of the applicable
series of trust preferred securities. THE GUARANTEE ONLY COVERS, HOWEVER,
DISTRIBUTIONS AND OTHER PAYMENTS ON TRUST PREFERRED SECURITIES IF AND TO THE
EXTENT THAT TRUSTMARK HAS MADE CORRESPONDING PAYMENTS ON THE DEBT SECURITIES TO
THE APPLICABLE PROPERTY TRUSTEE. IF TRUSTMARK DOES NOT MAKE THOSE CORRESPONDING
PAYMENTS ON THE DEBT SECURITIES, THE APPLICABLE TRMK TRUST WILL NOT HAVE FUNDS
AVAILABLE FOR PAYMENTS AND TRUSTMARK WILL HAVE NO OBLIGATION TO MAKE A GUARANTEE
PAYMENT.

     Trustmark's obligations under the declaration of trust for each TRMK Trust,
the guarantee, the debt securities and the associated indenture taken together
will provide a full and unconditional guarantee of payments due on the trust
preferred securities. We will describe the specific terms of the guarantee in a
prospectus supplement. See "Relationship Among The Trust Preferred Securities,
The Corresponding Junior Subordinated Debt Securities And The Guarantees" for a
discussion of other important terms and conditions of the guarantee.

COVENANTS OF TRUSTMARK

     In each guarantee, Trustmark will agree that, as long as trust preferred
securities issued by any TRMK Trust are outstanding, it will:

     - remain the sole direct or indirect owner of all the outstanding common
       securities of that TRMK Trust, except as permitted by the applicable
       declaration of trust;

     - permit the trust common securities of that TRMK Trust to be transferred
       only as permitted by the declaration of trust; and

     - use reasonable efforts to cause that TRMK Trust to continue to be treated
       as a grantor trust for United States federal income tax purposes, except
       in connection with a distribution of debt securities to the holders of
       trust preferred securities as provided in the declaration of trust, in
       which case the TRMK Trust would be dissolved.

                                        30


AMENDMENTS AND ASSIGNMENTS

     Trustmark and the guarantee trustee may amend each guarantee without the
consent of any holder of trust preferred securities if the amendment does not
adversely affect the rights of the holders in any material respect. In all other
cases, Trustmark and the guarantee trustee may amend each guarantee only with
the prior approval of the holders of at least a majority of outstanding trust
preferred securities issued by the applicable TRMK Trust.

     Trustmark may assign its obligations under the guarantees only in
connection with a consolidation, merger or asset sale involving Trustmark that
is permitted under the indenture governing the debt securities.

TERMINATION OF THE GUARANTEE

     A guarantee will terminate upon:

     - full payment of the redemption price of all trust preferred securities of
       the applicable TRMK Trust;

     - distribution of the related debt securities, or any securities into which
       those debt securities are convertible, to the holders of the trust
       preferred securities and trust common securities of that TRMK Trust in
       exchange for all the securities issued by that TRMK Trust; or

     - full payment of the amounts payable upon liquidation of that TRMK Trust.

     Each guarantee will, however, continue to be effective or will be
reinstated if any holder of trust preferred securities must repay any amounts
paid on those trust preferred securities or under the guarantee.

STATUS OF THE GUARANTEE

     Trustmark's obligations under each guarantee will be unsecured and
effectively junior to all debt and preferred stock of its subsidiaries. BY YOUR
ACCEPTANCE OF THE TRUST PREFERRED SECURITIES, YOU AGREE TO ANY SUBORDINATION
PROVISIONS AND OTHER TERMS OF THE RELATED GUARANTEE. We will specify in a
prospectus supplement the ranking of each guarantee with respect to Trustmark's
capital stock and other liabilities, including other guarantees.

     Each guarantee will be deposited with the guarantee trustee to be held for
your benefit. The guarantee trustee will have the right to enforce the guarantee
on your behalf. In most cases, the holders of a majority of outstanding trust
preferred securities issued by the applicable TRMK Trust will have the right to
direct the time, method and place of:

     - conducting any proceeding for any remedy available to the applicable
       guarantee trustee; or

     - exercising any trust or other power conferred upon that guarantee trustee
       under the applicable guarantee.

     Each guarantee will constitute a guarantee of payment and not merely of
collection. This means that the guarantee trustee may institute a legal
proceeding directly against Trustmark to enforce the payment rights under the
guarantee without first instituting a legal proceeding against any other person
or entity.

     If the guarantee trustee fails to enforce the guarantee or Trustmark fails
to make a guarantee payment, you may institute a legal proceeding directly
against Trustmark to enforce your rights under that guarantee without first
instituting a legal proceeding against the applicable TRMK Trust, the guarantee
trustee or any other person or entity.

PERIODIC REPORTS UNDER THE GUARANTEE

     Trustmark will be required to provide annually to the guarantee trustee a
statement as to its performance of its obligations and its compliance with all
conditions under the guarantees.

                                        31


DUTIES OF GUARANTEE TRUSTEE

     The guarantee trustee normally will perform only those duties specifically
set forth in the applicable guarantee. The guarantees do not contain any implied
covenants. If a default occurs on a guarantee, the guarantee trustee will be
required to use the same degree of care and skill in the exercise of its powers
under the guarantee as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs. The guarantee trustee will
exercise any of its rights or powers under the guarantee at the request or
direction of holders of the applicable series of trust preferred securities only
if it is offered security and indemnity satisfactory to it.

GOVERNING LAW

     The laws of the state of New York will govern the guarantees.

      RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES, THE CORRESPONDING
             JUNIOR SUBORDINATED DEBT SECURITIES AND THE GUARANTEES

     To the extent set forth in the guarantee and to the extent funds are
available, Trustmark will irrevocably guarantee the payment of distributions and
other amounts due on the trust securities as and to the extent set forth under
"Description Of Guarantees." Taken together, our obligations under the
declaration of trust for each TRMK Trust, the debt securities, the indenture and
the guarantee provide a full and unconditional guarantee of payments of
distributions and other amounts due on the trust securities. No single document
standing alone or operating in conjunction with fewer than all of the other
documents constitutes such guarantee. It is only the combined operation of these
documents that provides a full, irrevocable and unconditional guarantee of the
TRMK Trust's obligations under the trust securities.

     If and to the extent we do not make payments on the debt securities, the
TRMK Trust will not have sufficient funds to pay distributions or other amounts
due on the trust securities. The guarantee does not cover any payment of
distributions or other amounts due on the trust securities unless the TRMK Trust
has sufficient funds for the payment of such distributions or other amounts. In
such event, a holder of trust securities may institute a legal proceeding
directly against us to enforce payment of such distributions or other amounts to
such holder after the respective due dates.

SUFFICIENCY OF PAYMENTS

     As long as payments of interest and other amounts are made when due on the
debt securities, such payments will be sufficient to cover distributions and
payments due on the trust securities of a TRMK Trust because of the following
factors:

     - the aggregate principal amount of the debt securities will at least be
       equal to the sum of the aggregate stated liquidation amount of the trust
       securities;

     - the applicable interest rate and the interest and other payment dates on
       the debt securities will match the distribution rate and distribution and
       other payment dates for the trust securities;

     - Trustmark, as issuer of the debt securities, will pay, and the TRMK Trust
       will not be obligated to pay, directly or indirectly, any costs,
       expenses, debts and obligations of that TRMK Trust (other than the TRMK
       Trust's obligations with respect to the holders of the trust securities
       pursuant to the terms of those securities); and

     - the declaration of trust further provides that the TRMK Trust will not
       engage in any activity that is not consistent with the limited purposes
       of the TRMK Trust.

     Notwithstanding anything to the contrary in the indenture, we have the
right to set-off any payment we are otherwise required to make thereunder
against and to the extent we have already made, or are concurrently on the date
of such payment making, a related payment under the guarantee.

                                        32


ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES

     The declaration of trust provides that if we fail to make interest or other
payments on the debt securities when due (taking account of any extension
period), the holders of the trust preferred securities may direct the property
trustee to enforce its rights under the applicable indenture. If the property
trustee fails to enforce its rights under the indenture in respect of an event
of default under the indenture, any holder of record of trust preferred
securities may, to the fullest extent permitted by applicable law, institute a
legal proceeding against us to enforce the property trustee's rights under the
indenture without first instituting any legal proceeding against the property
trustee or any other person or entity. Notwithstanding the foregoing, if a trust
enforcement event has occurred and is continuing and such event is attributable
to our failure to pay interest, premium or principal on the debt securities on
the date such interest, premium or principal is otherwise payable, then a holder
of trust preferred securities may institute a direct action against us for
payment of such holder's pro rata share. If a holder brings such a direct
action, we will be entitled to that holder's rights under the applicable
declaration of trust to the extent of any payment made by us to that holder.

     If we fail to make payments under the guarantee, a holder of trust
preferred securities may institute a proceeding directly against us for
enforcement of the guarantee for such payments.

LIMITED PURPOSE OF TRUST

     The trust preferred securities evidence undivided beneficial interests in
the assets of the TRMK Trust, and the TRMK Trust exists for the sole purpose of
issuing and selling the trust securities and using the proceeds to purchase our
debt securities. A principal difference between the rights of a holder of trust
preferred securities and a holder of debt securities is that a holder of debt
securities is entitled to receive from us the principal amount of and interest
accrued on the debt securities held, while a holder of trust preferred
securities is entitled to receive distributions and other payments from the TRMK
Trust (or from us under the guarantee) only if and to the extent the TRMK Trust
has funds available for the payment of such distributions and other payments.

RIGHTS UPON DISSOLUTION

     Upon any voluntary or involuntary dissolution of the TRMK Trust involving
the redemption or repayment of the debt securities, the holders of the trust
securities will be entitled to receive, out of assets held by the TRMK Trust,
subject to the rights of creditors of the TRMK Trust, if any, the liquidation
distribution in cash. Because Trustmark is the guarantor under the guarantee
and, as issuer of the debt securities, Trustmark has agreed to pay for all
costs, expenses and liabilities of the TRMK Trust (other than the TRMK Trust's
obligations to the holders of the trust securities), the positions of a holder
of trust securities and a holder of debt securities relative to other creditors
and to our stockholders in the event of liquidation or bankruptcy of Trustmark
would be substantially the same.

ACCOUNTING TREATMENT RELATING TO TRUST SECURITIES

     The financial statements of any TRMK Trust issuing securities will be
consolidated with our financial statements, with the trust preferred securities
shown on our consolidated financial statements as Trustmark-obligated
mandatorily redeemable preferred capital trust securities of a subsidiary trust
holding solely Trustmark debt securities. Our financial statements will include
a footnote that discloses, among other things, that the assets of the TRMK Trust
consist of our debt securities and will specify the designation, principal
amount, interest rate and maturity date of the debt securities.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of certain material United States federal income
tax consequences of the ownership and disposition of the common stock, preferred
stock, and debt securities that may be offered hereunder. A summary of certain
material United States federal income tax consequences of the ownership

                                        33


and disposition of the other securities that may be offered hereunder will be
provided in the applicable prospectus supplement, as will any information that
updates or changes the information provided below. Unless otherwise stated, this
summary deals only with common stock, preferred stock and debt securities held
as capital assets by U.S. holders.

     As used herein, "U.S. holders" are any beneficial owners of the common
stock, preferred stock and debt securities that are, for United States federal
income tax purposes, (i) citizens or residents of the United States, (ii)
corporations created or organized in, or under the laws of, the United States,
any state thereof or the District of Columbia, (iii) estates, the income of
which is subject to United States federal income taxation regardless of its
source, or (iv) trusts if (a) a court within the United States is able to
exercise primary supervision over the administration of the trust and (b) one or
more United States persons have the authority to control all substantial
decisions of the trust. In addition, certain trusts in existence on August 20,
1996, and treated as a U.S. holder prior to such date may also be treated as
U.S. holders. As used herein, "non-U.S. holders" are beneficial owners of the
common stock, preferred stock and debt securities, other than partnerships, that
are not U.S. holders. If a partnership (including for this purpose any entity
treated as a partnership for United States federal tax purposes) is a beneficial
owner of the common stock, preferred stock or debt securities, the treatment of
a partner in the partnership will generally depend upon the status of the
partner and upon the activities of the partnership. Partnerships and partners in
such partnerships should consult their tax advisors about the United States
federal income tax consequences of owning and disposing of the common stock,
preferred stock, or debt securities.

     This summary does not describe all of the tax consequences that may be
relevant to a holder in light of its particular circumstances. For example, it
does not deal with special classes of holders such as banks, thrifts, real
estate investment trusts, regulated investment companies, insurance companies,
dealers in securities or currencies, or tax-exempt investors. It also does not
discuss common stock, preferred stock or debt securities held as part of a
hedge, straddle, "synthetic security" or other integrated transaction. This
summary does not address the tax consequences to (i) persons that have a
functional currency other than the U.S. dollar, (ii) certain U.S. expatriates,
or (iii) shareholders, partners or beneficiaries of a holder of the common
stock, preferred stock or debt securities. Further, it does not include any
description of any alternative minimum tax consequences or the tax laws of any
state or local government or of any foreign government that may be applicable to
the common stock, preferred stock or debt securities. This summary is based on
the Internal Revenue Code of 1986, as amended, the Treasury regulations
promulgated thereunder and administrative and judicial interpretations thereof,
all as of the date hereof, and all of which are subject to change or differing
interpretations, possibly on a retroactive basis.

     YOU SHOULD CONSULT WITH YOUR OWN TAX ADVISOR REGARDING THE FEDERAL, STATE,
LOCAL AND FOREIGN INCOME, FRANCHISE, PERSONAL PROPERTY, AND ANY OTHER TAX
CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF THE COMMON STOCK, PREFERRED
STOCK OR DEBT SECURITIES.

TAXATION OF COMMON STOCK

     This subsection describes certain material United States federal income tax
consequences of owning and disposing of the common stock that we may offer.

  U.S. HOLDERS OF COMMON STOCK

  Dividends

     The amount of any distribution we make in respect of our common stock will
be equal to the amount of cash and the fair market value, on the date of
distribution, of any property distributed. Generally, distributions will be
treated as a dividend, subject to tax as ordinary income, to the extent of our
current or accumulated earnings and profits, then as a tax-free return of
capital to the extent of a holder's tax basis in the common stock and thereafter
as gain from the sale or exchange of such stock as described below.

     In general, a dividend distribution to a corporate holder will qualify for
the 70% dividends-received deduction. The dividends-received deduction is
subject to certain holding period, taxable income, and other

                                        34


limitations (see "-- Taxation of Preferred Stock -- U.S. Holders of Preferred
Stock -- Dividends to Corporate Holders" below).

  Sale or Exchange of Common Stock

     Upon the sale or exchange of common stock, a holder generally will
recognize capital gain or loss equal to the difference between (1) the amount of
cash and the fair market value of any property received upon the sale or
exchange and (2) such holder's tax basis in the common stock (which is generally
equal to the price paid by the holder to acquire the stock). In the case of a
holder other than a corporation, preferential tax rates may apply to such gain
if the holder's holding period for the common stock exceeds one year. Subject to
certain limited exceptions, capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.

  Information Reporting and Backup Withholding Tax

     In general, information reporting requirements will apply to payments of
dividends on common stock and payments of the proceeds of the sale of common
stock, and a backup withholding tax may apply to such payments if the holder
fails to comply with certain identification requirements. Back-up withholding is
currently imposed at a rate of 30%. Any amounts withheld under the backup
withholding rules from a payment to a holder will be allowed as a credit against
such holder's United States federal income tax and may entitle the holder to a
refund, provided that the required information is furnished to the Internal
Revenue Service.

  NON-U.S. HOLDERS OF COMMON STOCK

     The rules governing United States federal income taxation of a non-U.S.
holder of common stock are complex and no attempt will be made herein to provide
more than a summary of such rules. Non-U.S. holders should consult with their
own tax advisors to determine the effect of federal, state, local and foreign
income tax laws, as well as treaties, with regard to an investment in the common
stock, including any reporting requirements.

  Dividends

     Distributions by us with respect to the common stock that are treated as
dividends paid, as described above under "U.S. Holders of Common
Stock -- Dividends," to a non-U.S. holder (excluding dividends that are
effectively connected with the conduct of a United States trade or business by
such holder and are taxable as described below) will be subject to United States
federal withholding tax at a 30% rate (or such lower rate as may be specified by
an applicable income tax treaty). Except to the extent that an applicable income
tax treaty otherwise provides, a non-U.S. holder will be taxed in the same
manner as a U.S. holder on dividends paid (or deemed paid) that are effectively
connected with the conduct of a United States trade or business by the non-U.S.
holder. If such non-U.S. holder is a foreign corporation, it may also be subject
to a United States branch profits tax on such effectively connected income at a
30% rate (or such lower rate as may be specified by an applicable income tax
treaty). Even though such effectively connected dividends are subject to income
tax and may be subject to the branch profits tax, they will not be subject to
United States federal withholding tax if the holder delivers a properly executed
Internal Revenue Service Form W-8ECI (or successor form) to the payor or the
payor's agent.

     A non-U.S. holder who wishes to claim the benefit of an applicable income
tax treaty is required to satisfy certain certification and other requirements.
If you are eligible for a reduced rate of United States withholding tax pursuant
to an income tax treaty, you may obtain a refund of any excess amounts withheld
by filing an appropriate claim for refund with the Internal Revenue Service.

  Sale or Exchange of Common Stock

     A non-U.S. holder generally will not be subject to United States federal
income tax or withholding tax on the sale or exchange of common stock unless (1)
the gain is effectively connected with a United
                                        35


States trade or business of the non-U.S. holder, (2) in the case of a non-U.S.
holder who is an individual, such holder is present in the United States for a
period or periods aggregating 183 days or more during the taxable year of the
disposition, and either (a) such holder has a "tax home" in the United States or
(b) the disposition is attributable to an office or other fixed place of
business maintained by such holder in the United States, (3) the non-U.S. holder
is subject to tax pursuant to the provisions of the Internal Revenue Code
applicable to certain United States expatriates or (4) we are characterized as a
United States real property holding corporation for United States federal income
tax purposes. We believe that we are not currently, and do not anticipate
becoming, a United States real property holding corporation.

     If an individual non-U.S. holder falls under clause (1) above, such
individual generally will be taxed on the net gain derived from a sale in the
same manner as a U.S. holder. If an individual non-U.S. holder falls under
clause (2) above, such individual generally will be subject to a flat 30% tax on
the gain derived from a sale, which may be offset by certain United States
capital losses (notwithstanding the fact that such individual is not considered
a resident of the United States). Individual non-U.S. holders who have spent (or
expect to spend) 183 days or more in the United States in the taxable year in
which they contemplate a sale of common stock are urged to consult their tax
advisors as to the tax consequences of such sale. If a non-U.S. holder that is a
foreign corporation falls under clause (1), it generally will be taxed on the
net gain derived from a sale in the same manner as a U.S. holder and, in
addition, may be subject to the branch profits tax on such effectively connected
income at a 30% rate (or such lower rate as may be specified by an applicable
income tax treaty).

  Information Reporting and Backup Withholding Tax

     Dividends on common stock held by a non-U.S. holder will be subject to
information reporting and may be subject to backup withholding requirements
unless certain certification requirements are satisfied. United States
information reporting requirements and backup withholding tax will not apply to
any payment of the proceeds of the sale of common stock effected outside the
United States by a foreign office of a "broker" as defined in applicable
Treasury regulations, unless such broker (1) is a United States person as
defined in the Internal Revenue Code, (2) is a foreign person that derives 50%
or more of its gross income for certain periods from the conduct of a trade or
business in the United States, (3) is a controlled foreign corporation for
United States federal income tax purposes or (4) is a foreign partnership with
certain U.S. connections. Payment of the proceeds of any such sale effected
outside the United States by a foreign office of any broker that is described in
the preceding sentence may be subject to backup withholding tax and information
reporting requirements, unless such broker has documentary evidence in its
records that the beneficial owner is a non-U.S. holder and certain other
conditions are met, or the beneficial owner otherwise establishes an exemption.
Payment of the proceeds of any such sale to or through the United States office
of a broker is subject to backup withholding tax and information reporting
requirements unless the beneficial owner of the common stock certifies to the
payor or the payor's agent, under penalties of perjury, that it is not a United
States person and provides its name, address and certain other information on a
properly executed Internal Revenue Service Form W-8BEN or a suitable substitute
form or otherwise establishes an exemption.

     THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO
THE TAX CONSEQUENCES TO THEM OF THE OWNERSHIP AND DISPOSITION OF COMMON STOCK,
INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS
AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR OTHER TAX LAWS.

TAXATION OF PREFERRED STOCK

     This subsection describes certain material United States federal income tax
consequences of owning and disposing of the preferred stock that we may offer.

                                        36


  U.S. HOLDERS OF PREFERRED STOCK

  Dividends

     The amount of any distribution we make in respect of our preferred stock
will be equal to the amount of cash and the fair market value, on the date of
distribution, of any property (including common stock) distributed. Generally,
distributions will be treated as a dividend, subject to tax as ordinary income,
to the extent of our current or accumulated earnings and profits, then as a
tax-free return of capital to the extent of a holder's tax basis in the
preferred stock and thereafter as gain from the sale or exchange of such stock
as described below.

  Dividends to Corporate Holders

     A dividend distribution to a corporate holder will generally qualify for
the 70% dividends-received deduction. In determining entitlement to the
dividends-received deduction, corporate holders should consider the provisions
of Sections 246(c), 246A and 1059 of the Internal Revenue Code, as well as
Treasury regulations and Internal Revenue Service rulings and administrative
pronouncements relating to such provisions. Under current law, Section 246(c) of
the Internal Revenue Code disallows the dividends-received deduction in its
entirety if the holder does not satisfy the applicable holding period
requirement for the dividend-paying stock for a period beginning before and
ending after such holder becomes entitled to receive each dividend on the stock.
Section 246(c)(4) of the Internal Revenue Code provides that a holder may not
count toward this minimum holding period any period in which the holder (1) has
an option to sell, is under a contractual obligation to sell, or has made (and
not closed) a short sale of, substantially identical stock or securities, or (2)
has diminished its risk of loss by holding one or more positions with respect to
substantially similar or related property. Under certain circumstances, Section
1059 of the Internal Revenue Code (a) reduces the tax basis of stock by a
portion of any "extraordinary dividends" that are eligible for the
dividends-received deduction and (b) to the extent that the basis reduction
would otherwise reduce the tax basis of the stock below zero, requires immediate
recognition of gain, which is treated as gain from the sale or exchange of the
stock. An "extraordinary dividend" includes any amount treated as a dividend
with respect to a redemption that is not pro rata to all stockholders (or meets
certain other requirements), without regard to either the relative amount of the
dividend or the holder's holding period for the stock. Section 246A of the
Internal Revenue Code contains the "debt-financed" portfolio stock rules, under
which the dividends-received deduction could be reduced to the extent that a
holder incurs indebtedness directly attributable to its investment in the stock.

  Receipt of Common Stock Upon Conversion of the Preferred Stock

     If the preferred stock is convertible into common stock, gain or loss will
not be recognized by a holder upon the conversion of such preferred stock into
common stock if no cash is received. A holder who receives cash in lieu of a
fractional share of common stock will in general be treated as having received
such fractional share and having exchanged it for cash in a redemption, which
would be treated in the manner described under "Sale, Exchange or Redemption of
Preferred Stock" below. As discussed therein, a holder who cannot qualify for
sale or exchange treatment under the rules applicable to redemptions will
generally be taxable on the cash received in lieu of a fractional share as a
distribution described in "-- Dividends" above.

     A holder's tax basis in the common stock received upon conversion will
generally be equal to the holder's tax basis in the preferred stock less the tax
basis allocated to any fractional share for which cash is received, and a
holder's holding period in the common stock received upon conversion generally
will include the period during which the preferred stock was held by such
holder.

  Adjustments of Conversion Price in Respect of Preferred Stock

     If the preferred stock is convertible into common stock, adjustments to the
conversion price ratio to take into account a stock dividend or stock split
generally will not be taxable. However, an adjustment to the conversion price
ratio to reflect the issuance of certain rights, warrants, evidences of
indebtedness,
                                        37


securities or other assets to holders of common stock (an "Adjustment") may
result in constructive distributions to the holders of the preferred stock. The
amount of any such constructive distribution would be the fair market value on
the date of the Adjustment of the number of shares of common stock which, if
actually distributed to holders of preferred stock, would produce the same
increase in the proportionate interests of such holders in our assets or
earnings and profits as that produced by the Adjustment. The distribution would
be treated in the manner described above under "-- Dividends."

  Excessive Redemption Price of Preferred Stock

     Under Section 305 of the Internal Revenue Code and the applicable Treasury
regulations, if preferred stock with a mandatory redemption date or preferred
stock subject to certain redemption rights on the part of either us or the
holder of such stock has a redemption price that exceeds its issue price (i.e.,
its fair market value at its date of original issuance) by more than a de
minimis amount, such excess may be treated as a constructive distribution that
will be treated in the same manner as distribution described above under
"-- Dividends." A holder of such preferred stock would be required to treat such
excess as a constructive distribution received by the holder over the life of
such stock under a constant interest (economic yield) method that takes into
account the compounding of yield.

  Accrued Dividends on the Preferred Stock

     The tax treatment of accrued dividends that are payable upon a redemption
of the preferred stock will be addressed in the applicable prospectus
supplement.

  Sale, Exchange or Redemption of Preferred Stock

     Upon the sale or exchange of preferred stock, a holder generally will
recognize capital gain or loss equal to the difference between (1) the amount of
cash and the fair market value of any property received upon the sale or
exchange and (2) such holder's tax basis in the stock (which is generally equal
to the price paid by the holder to acquire the stock). In the case of a holder
other than a corporation, preferential tax rates may apply to such gain if the
holder's holding period for the preferred stock exceeds one year. Subject to
certain limited exceptions, capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.

     Gain or loss recognized by a holder on a redemption of the preferred stock
will be treated as a sale or exchange and therefore qualify for the treatment
described above if certain requirements are satisfied. Generally, these
requirements are satisfied if either (1) the holder's interest in our stock is
completely terminated as a result of such redemption, (2) such holder's
percentage ownership of our voting stock immediately after the redemption is
less than 80% of such holder's percentage ownership immediately before the
redemption or (3) the redemption is "not essentially equivalent to a dividend."
The attribution rules of Section 318 of the Internal Revenue Code treat a person
as owning stock owned by certain related parties or certain entities in which
the person owns an interest and stock that a person could acquire through
exercise of an option. For this purpose, an option would include any conversion
right under the preferred stock. Whether a redemption is "not essentially
equivalent to a dividend" depends on each holder's facts and circumstances, but
in any event requires a "meaningful reduction" in such holder's equity interest
in us. A holder of the preferred stock who sells some or all of our stock owned
by it may be able to take such sales into account to satisfy one of the
foregoing conditions. Conversely, a holder who purchases additional shares of
our stock may be required to take such purchases into account in determining
whether any of the foregoing conditions are satisfied.

     If none of the above requirements for sale or exchange treatment is
satisfied, the entire amount of the cash (or property) received on a redemption
(without offset by the holder's tax basis in the redeemed shares) will generally
be treated in the same manner as distributions described above under
'-- Dividends" and the holder's basis in the redeemed preferred stock will be
transferred to the holder's remaining shares of our stock (if any). If the
holder does not retain any shares of our stock but dividend treatment arises
because of the constructive ownership rules, such basis may be entirely lost to
the holder. The Internal

                                        38


Revenue Service has recently issued proposed regulations that would change the
treatment of the basis of redeemed stock when a distribution in redemption of
such stock is characterized as a dividend. The regulations are proposed to be
effective for transactions occurring after the date on which the proposed
regulations are made final and are subject to change prior to their adoption in
final form. Holders should consult their tax advisors regarding the potential
effects of the regulations.

  Other Preferred Stock

     Special tax rules may apply to certain types of preferred stock. The
applicable prospectus supplement will discuss any such special United States
federal income tax rules with respect to such preferred stock.

  Information Reporting and Backup Withholding Tax

     In general, information reporting requirements will apply to payments of
dividends on the preferred stock and payments of the proceeds of the sale of the
preferred stock, and a backup withholding tax may apply to such payments if the
holder fails to comply with certain identification requirements. Backup
withholding is currently imposed at a rate of 30%. Any amounts withheld under
the backup withholding rules from a payment to a holder will be allowed as a
credit against such holder's United States federal income tax and may entitle
the holder to a refund, provided that the required information is furnished to
the Internal Revenue Service.

  NON-U.S. HOLDERS OF PREFERRED STOCK

     The rules governing United States federal income taxation of a non-U.S.
holder of preferred stock are complex and no attempt will be made herein to
provide more than a summary of such rules. Non-U.S. holders should consult with
their own tax advisors to determine the effect of federal, state, local and
foreign income tax laws, as well as treaties, with regard to an investment in
the preferred stock, including any reporting requirements.

  Dividends

     Distributions by us with respect to the preferred stock that are treated as
dividends paid (or deemed paid), as described above under "-- Dividends" and
"-- Sale, Exchange or Redemption of Preferred Stock," to a non-U.S. holder
(excluding dividends that are effectively connected with the conduct of a United
States trade or business by such holder and are taxable as described below) will
be subject to United States federal withholding tax at a 30% rate (or such lower
rate as may be specified by an applicable income tax treaty). Except to the
extent that an applicable income tax treaty otherwise provides, a non-U.S.
holder will be taxed in the same manner as a U.S. holder on dividends paid (or
deemed paid) that are effectively connected with the conduct of a United States
trade or business by the non-U.S. holder. If such non-U.S. holder is a foreign
corporation, it may also be subject to a United States branch profits tax on
such effectively connected income at a 30% rate (or such lower rate as may be
specified by an applicable income tax treaty). Even though such effectively
connected dividends are subject to income tax, and may be subject to the branch
profits tax, they will not be subject to United States withholding tax if the
holder delivers a properly executed Internal Revenue Service Form W-8ECI (or
successor form) to the payor or the payor's agent.

     A non-U.S. holder who wishes to claim the benefit of an applicable income
tax treaty is required to satisfy certain certification and other requirements.
If you are eligible for a reduced rate of United States withholding tax pursuant
to an income tax treaty, you may obtain a refund of any excess amounts withheld
by filing an appropriate claim for refund with the Internal Revenue Service.

  Receipt of Common Stock Upon Conversion of the Preferred Stock

     In general, no United States federal income tax or withholding tax will be
imposed upon the conversion of preferred stock into common stock by a non-U.S.
holder (except with respect to the non-

                                        39


U.S. holder's receipt of cash in lieu of fractional shares where one of the
conditions described below under "-- Sale, Exchange or Redemption of Preferred
Stock" is satisfied).

  Sale, Exchange or Redemption of Preferred Stock

     A non-U.S. holder generally will not be subject to United States federal
income tax or withholding tax on the sale or exchange of preferred stock unless
(1) the gain is effectively connected with a United States trade or business of
the non-U.S. holder, (2) in the case of a non-U.S. holder who is an individual,
such holder is present in the United States for a period or periods aggregating
183 days or more during the taxable year of the disposition, and either (a) such
holder has a "tax home" in the United States or (b) the disposition is
attributable to an office or other fixed place of business maintained by such
holder in the United States, (3) the non-U.S. holder is subject to tax pursuant
to the provisions of the Internal Revenue Code applicable to certain United
States expatriates or (4) we are characterized as a United States real property
holding corporation for United States federal income tax purposes. We believe
that we are not currently, and do not anticipate becoming, a United States real
property holding corporation.

     If an individual non-U.S. holder falls under clause (1) above, such
individual generally will be taxed on the net gain derived from a sale in the
same manner as a U.S. holder. If an individual non-U.S. holder falls under
clause (2) above, such individual generally will be subject to a flat 30% tax on
the gain derived from a sale, which may be offset by certain United States
capital losses (notwithstanding the fact that such individual is not considered
a resident of the United States). Individual non-U.S. holders who have spent (or
expect to spend) 183 days or more in the United States in the taxable year in
which they contemplate a sale of preferred stock are urged to consult their tax
advisors as to the tax consequences of such sale. If a non-U.S. holder that is a
foreign corporation falls under clause (1) above, it generally will be taxed on
the net gain derived from a sale in the same manner as a U.S. holder and, in
addition, may be subject to the branch profits tax on such effectively connected
income at a 30% rate (or such lower rate as may be specified by an applicable
income tax treaty).

     Gain or loss realized by a non-U.S. holder on a redemption of the preferred
stock will be treated as a sale or exchange and qualify for the treatment
described in this section if certain requirements are satisfied. For a
description of these requirements, see "-- U.S. Holders -- Sale, Exchange or
Redemption of Preferred Stock" above. If such requirements are not satisfied,
then the entire amount of the cash (or property) received on a redemption
(without offset by the holder's tax basis in the redeemed shares) will generally
be treated in the same manner as distributions described above under
"-- Dividends" and the holder's basis in the redeemed preferred stock will be
transferred to the holder's remaining shares of our stock (if any). If the
holder does not retain any shares of our stock but dividend treatment arises
because of the constructive ownership rules described in "-- U.S.
Holders -- Sale, Exchange or Redemption of Preferred Stock," such basis may be
entirely lost to the holder. The Internal Revenue Service has recently issued
proposed regulations that would change the treatment of the basis of redeemed
stock when a distribution in redemption of such stock is characterized as a
dividend. The regulations are proposed to be effective for transactions
occurring after the date on which the proposed regulations are made final and
are subject to change prior to their adoption in final form. Holders should
consult their tax advisors regarding the potential effects of the regulations.

  Information Reporting and Backup Withholding Tax

     Dividends on preferred stock held by a non-U.S. holder will be subject to
information reporting and may be subject to backup withholding requirements
unless certain certification requirements are satisfied. United States
information reporting requirements and backup withholding tax will not apply to
any payment of the proceeds of the sale of preferred stock effected outside the
United States by a foreign office of a "broker" as defined in applicable
Treasury regulations, unless such broker (1) is a United States person as
defined in the Internal Revenue Code, (2) is a foreign person that derives 50%
or more of its gross income for certain periods from the conduct of a trade or
business in the United States, (3) is a controlled foreign corporation for
United States federal income tax purposes or (4) is a foreign partnership with
certain U.S. connections. Payment of the proceeds of any such sale effected
outside the United States
                                        40


by a foreign office of any broker that is described in the preceding sentence
may be subject to backup withholding tax and information reporting requirements,
unless such broker has documentary evidence in its records that the beneficial
owner is a non-U.S. holder and certain other conditions are met, or the
beneficial owner otherwise establishes an exemption. Payment of the proceeds of
any such sale to or through the United States office of a broker is subject to
backup withholding tax and information reporting requirements unless the
beneficial owner of the preferred stock certifies to the payor or the payor's
agent, under penalties of perjury, that it is not a United States person and
provides its name, address and certain other information on a properly executed
Internal Revenue Service Form W-8BEN or a suitable substitute form or otherwise
establishes an exemption.

     THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO
THE TAX CONSEQUENCES TO THEM OF THE OWNERSHIP AND DISPOSITION OF THE PREFERRED
STOCK, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX
LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR OTHER TAX
LAWS.

TAXATION OF DEBT SECURITIES

     This subsection describes certain material United States federal income tax
consequences of owning and disposing of the debt securities that we may offer.
It deals only with debt securities that are due to mature 30 years or less from
the date on which they are issued. The United States federal income tax
consequences of owning and disposing of debt securities that are due to mature
more than 30 years from the date of issue will be discussed in an applicable
prospectus supplement. The discussion regarding United States federal income tax
laws assumes that any debt securities will be issued, and transfers thereof and
payments thereon will be made, in accordance with the applicable indenture and
deposit agreement.

  U.S. HOLDERS OF DEBT SECURITIES

  Interest Income

     Subject to the original issue discount rules described below, payments of
interest on the debt securities generally will be taxable to a U.S. holder as
ordinary interest income at the time such payments are accrued or received (in
accordance with the holder's regular method of tax accounting).

     A debt security will be treated as issued with original issue discount
("OID") if its stated redemption price at maturity exceeds its issue price by
more than a de minimis amount. Generally, the issue price will be the first
price at which a substantial amount of the debt securities is sold to persons
other than bond houses, brokers or similar persons or organizations acting in
the capacity of underwriters, placement agents or wholesalers. A debt security's
stated redemption price at maturity is the total of all payments on the debt
security that are not payments of qualified stated interest. An interest payment
is qualified stated interest if it is one of a series of stated interest
payments that are unconditionally payable at least annually at a single fixed
rate.

     A debt security is not treated as issued with OID if the OID (i.e., the
excess of the stated redemption price at maturity over the issue price) is de
minimis. For this purpose the amount of OID is de minimis if it does not exceed
the product of 0.25 percent of the stated redemption price at maturity
multiplied by the number of complete years to maturity. If the debt security has
de minimis OID, a holder must generally include the de minimis amount in income
(as capital gain) as stated principal payments are made.

     If the debt security is treated as issued with OID, a U.S. holder will be
required to include the amount of the OID in income periodically over the term
of the debt security before receipt of the cash or other payment attributable to
such income and irrespective of such holder's general method of tax accounting.
More specifically, a U.S. holder of a debt security must include in gross
income, as interest for United States federal income tax purposes, the sum of
the daily portions of OID with respect to the debt security for each day during
the taxable year or portion of a taxable year in which such holder holds the
debt security ("accrued OID"). The daily portion is determined by allocating to
each day of an accrual

                                        41


period a pro rata portion of an amount equal to the adjusted issue price of the
debt security at the beginning of the accrual period multiplied by the yield to
maturity of the debt security and subtracting from this product the amount of
qualified stated interest allocable to the accrual period. The adjusted issue
price of the debt security at the start of any accrual period is the issue price
of the debt security increased by the accrued OID for each prior accrual period
and decreased by the amount of any payments previously made with respect to the
debt security (other than qualified stated interest).

  Debt Securities Purchased with Market Discount

     A holder will be considered to have purchased a debt security with "market
discount" if the holder's adjusted basis in the debt security immediately after
purchase is less than the debt security's stated redemption price at maturity,
or in the case of a debt security issued with OID, the debt security's revised
issue price (which has the same meaning as "adjusted issue price" as defined
above). A debt security is not treated as having market discount if the amount
of market discount is de minimis. For this purpose, the amount of market
discount is de minimis if it does not exceed the product of 0.25 percent of the
stated redemption price at maturity or the revised issue price, as the case may
be, on the purchase date multiplied by the number of complete years to maturity
remaining as of such date. If the debt security has de minimis market discount,
a holder must generally include such de minimis amount in income (as capital
gain) as stated principal payments are made.

     If a debt security is treated as having market discount, any partial
payment of principal on, or gain recognized on the maturity or disposition of,
the debt security will generally be treated as ordinary income to the extent
that such gain does not exceed the accrued market discount on the debt security.
Alternatively, a holder of a debt security may elect to include market discount
in income currently over the life of the debt security. Such an election applies
to all debt instruments with market discount acquired by the electing holder on
or after the first day of the first taxable year to which the election applies
and may not be revoked without the consent of the Internal Revenue Service.
Market discount accrues on a straight-line basis unless the holder elects to
accrue such discount on a constant yield to maturity basis. This latter election
is applicable only to the debt security with respect to which it is made and is
irrevocable. A holder of a debt security that does not elect to include market
discount in income currently generally will be required to defer deductions for
interest on borrowings allocable to such debt security in an amount not
exceeding the accrued market discount on such debt security until the maturity
or disposition of such debt security.

  Debt Securities Purchased at a Premium

     A holder will be considered to have purchased a debt security at a premium
if the holder's tax basis in the debt security immediately after the purchase
(which does not include any amount paid in respect of accrued interest on the
debt security) is greater than the amount payable on maturity. A holder may
elect to treat such premium as "amortizable bond premium," in which case the
amount of interest required to be included in the holder's income each year with
respect to the interest on the debt security will be reduced by the amount of
the amortizable bond premium allocable (generally under a constant yield method
based on the holder's yield to maturity) to such year with a corresponding
decrease in the holder's tax basis in the debt security. Any election to
amortize bond premium is applicable to all debt securities (other than a
tax-exempt debt security) held by the holder at the beginning of the first
taxable year to which the election applies or thereafter acquired by the holder,
and may not be revoked without the consent of the Internal Revenue Service.

     A holder who purchases a debt security issued with OID for an amount that
is greater than the debt security's adjusted issue price but less than or equal
to the sum of all amounts payable on the debt security after the purchase date
other than payments of qualified stated interest will be considered to have
purchased the debt security at an acquisition premium. Under the acquisition
premium rules, the amount of OID that the holder must include in its gross
income with respect to the debt security for any taxable year will be reduced by
the portion of acquisition premium properly allocable to that year.

                                        42


  Sale or Exchange of Debt Securities

     A holder will generally recognize capital gain or loss equal to the
difference between the amount realized on the sale, exchange or other
disposition of the debt security and the holder's adjusted tax basis in such
debt security, except that ordinary income will be recognized to the extent that
a portion of the amount realized is attributable to market discount or accrued
interest not previously included in income. A holder's adjusted tax basis in the
debt security generally will be the price paid by the holder to acquire the debt
security, increased by any OID or market discount previously included in income
with respect to the debt security and reduced by any amortizable bond premium
and any payments previously received with respect to the debt security other
than qualified stated interest. In the case of a holder other than a
corporation, preferential tax rates may apply to gain recognized on the sale of
a debt security if such holder's holding period for such debt security exceeds
one year. Subject to certain limited exceptions, capital losses cannot be
applied to offset ordinary income for United States federal income tax purposes.

  Other Debt Securities

     Special tax rules may apply to certain types of debt securities including,
but not limited to, debt securities subject to contingencies, variable rate debt
securities and debt securities convertible into our equity. The applicable
prospectus supplement will discuss any such special United States federal income
tax rules with respect to such debt securities.

  Information Reporting and Backup Withholding Tax

     In general, information reporting requirements will apply to payments of
principal, premium, if any, and interest on the debt securities and payments of
the proceeds of the sale of the debt securities, and a backup withholding tax
may apply to such payments if the holder fails to comply with certain
identification requirements. Backup withholding is currently imposed at a rate
of 30%. Any amounts withheld under the backup withholding rules from a payment
to a holder will be allowed as a credit against such holder's United States
federal income tax and may entitle the holder to a refund, provided that the
required information is furnished to the Internal Revenue Service.

  NON-U.S. HOLDERS OF DEBT SECURITIES

     The rules governing United States federal income taxation of a non-U.S.
holder of debt securities are complex and no attempt will be made herein to
provide more than a summary of such rules. Non-U.S. holders should consult with
their own tax advisors to determine the effect of federal, state, local and
foreign income tax laws, as well as treaties, with regard to an investment in
the debt securities, including any reporting requirements.

     This discussion assumes that the debt security or coupon is not subject to
the rules of Section 871(h)(4)(A) of the Internal Revenue Code, relating to
interest payments that are determined by reference to income, profits, changes
in value of property or other attributes of us or a related party.

  Interest Income

     Generally, interest income of a non-U.S. holder that is not effectively
connected with a United States trade or business will be subject to a
withholding tax at a 30% rate (or such lower tax rate as may be specified by an
applicable income tax treaty). However, interest income earned on a debt
security by a non-U.S. holder will qualify for the "portfolio interest"
exemption and therefore will not be subject to United States federal income tax
or withholding tax, provided that such interest income is not effectively
connected with a United States trade or business of the non-U.S. holder and
provided that (1) the non-U.S. holder does not actually or constructively own
10% of more of the total combined voting power of all classes of our stock
entitled to vote; (2) the non-U.S. holder is not a controlled foreign
corporation that is related to us through stock ownership; (3) the non-U.S.
holder is not a bank which acquired the debt security in consideration for an
extension of credit made pursuant to a loan agreement entered into in the
ordinary course of business; and (4) either (a) the non-U.S. holder certifies to
the payor or the payor's
                                        43


agent, under penalties of perjury, that it is not a United States person and
provides its name, address, and certain other information on a properly executed
Internal Revenue Service Form W-8BEN or a suitable substitute form or (b) a
securities clearing organization, bank or other financial institution that holds
customer securities in the ordinary course of its trade or business and holds
the debt securities in such capacity, certifies to the payor or the payor's
agent, under penalties of perjury, that such a statement has been received from
the beneficial owner by it or by a financial institution between it and the
beneficial owner, and furnishes the payor or the payor's agent with a copy
thereof. The applicable United States Treasury regulations also provide
alternative methods for satisfying the certification requirements of clause (4),
above. Special certification rules apply for debt securities held by a foreign
partnership and other intermediaries.

     Except to the extent that an applicable income tax treaty otherwise
provides, a non-U.S. holder generally will be taxed with respect to interest in
the same manner as a U.S. holder if the interest is effectively connected with a
United States trade or business of the non-U.S. holder. Effectively connected
interest income received or accrued by a corporate non-U.S. holder may also,
under certain circumstances, be subject to an additional branch profits tax at a
30% rate (or such lower tax rate as may be specified by an applicable income tax
treaty). Even though such effectively connected income is subject to income tax,
and may be subject to the branch profits tax, it is not subject to withholding
tax if the non-U.S. holder delivers a properly executed Internal Revenue Service
Form W-8ECI (or successor form) to the payor or the payor's agent.

  Sale or Exchange of Debt Securities

     A non-U.S. holder generally will not be subject to United States federal
income tax or withholding tax on any gain realized on the sale, exchange or
other disposition of a debt security unless (1) the gain is effectively
connected with a United States trade or business of the non-U.S. holder, (2) in
the case of a non-U.S. holder who is an individual, such holder is present in
the United States for a period or periods aggregating 183 days or more during
the taxable year of the disposition, and either such holder has a "tax home" in
the United States or the disposition is attributable to an office or other fixed
place of business maintained by such holder in the United States or (3) the
non-U.S. holder is subject to tax pursuant to the provisions of the Internal
Revenue Code applicable to certain United States expatriates.

     If an individual non-U.S. holder falls under clause (1) above, such
individual generally will be taxed on the net gain derived from a sale in the
same manner as a U.S. holder. If an individual non-U.S. holder falls under
clause (2) above, such individual generally will be subject to a flat 30% tax on
the gain derived from a sale, which may be offset by certain United States
capital losses (notwithstanding the fact that such individual is not considered
a resident of the United States). Individual non-U.S. holders who have spent (or
expect to spend) 183 days or more in the United States in the taxable year in
which they contemplate a sale or other disposition of a debt security are urged
to consult their tax advisors as to the tax consequences of such sale. If a
non-U.S. holder that is a foreign corporation falls under clause (1), it
generally will be taxed on the net gain derived from a sale in the same manner
as a U.S. holder and, in addition, may be subject to the branch profits tax on
such effectively connected income at a 30% rate (or such lower rate as may be
specified by an applicable income tax treaty).

  Information Reporting and Backup Withholding Tax

     United States backup withholding tax will not apply to payments on the debt
securities to a non-U.S. holder if the statement described in clause (4) of
"Interest Income" is duly provided by such holder, provided that the payor does
not have actual knowledge that the holder is a United States person. Information
reporting requirements may apply with respect to interest payments on the debt
securities, in which event the amount of interest paid and tax withheld (if any)
with respect to each non-U.S. holder will be reported annually to the Internal
Revenue Service. Information reporting requirements and backup withholding tax
will not apply to any payment of the proceeds of the sale of debt securities
effected outside the United States by a foreign office of a "broker" as defined
in applicable Treasury regulations (absent actual knowledge that the payee is a
United States person), unless such broker (1) is a United
                                        44


States person as defined in the Internal Revenue Code, (2) is a foreign person
that derives 50% or more of its gross income for certain periods from the
conduct of a trade or business in the United States, (3) is a controlled foreign
corporation for United States federal income tax purposes or (4) is a foreign
partnership with certain U.S. connections. Payment of the proceeds of any such
sale effected outside the United States by a foreign office of any broker that
is described in the preceding sentence may be subject to backup withholding tax
and information reporting requirements, unless such broker has documentary
evidence in its records that the beneficial owner is a non-U.S. holder and
certain other conditions are met, or the beneficial owner otherwise establishes
an exemption. Payment of the proceeds of any such sale to or through the United
States office of a broker is subject to information reporting and backup
withholding requirements unless the beneficial owner of the debt securities
provides the statement described in clause (4) of "Interest Income" or otherwise
establishes an exemption.

     THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO
THE TAX CONSEQUENCES TO THEM OF THE OWNERSHIP AND DISPOSITION OF THE DEBT
SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER
TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR OTHER
TAX LAWS.

                              BOOK ENTRY ISSUANCE

GENERAL PROCEDURES RELATED TO DTC

     Unless otherwise specified in the prospectus supplement, each series of
debt securities will be represented by one or more global notes registered in
the name of a nominee of The Depository Trust Company ("DTC"), as depositary.
Upon the issuance of the global notes, DTC or its custodian will credit, on its
internal system, the respective principal amount of the individual beneficial
interests represented by the global notes to the accounts of persons who have
accounts with DTC, known as "participants." Each account initially will be
designated by or on behalf of the underwriters, dealer or agents. Ownership of
beneficial interests in a global note will be limited to participants, or
persons who hold interests through participants. Ownership of beneficial
interests in the global notes will be shown on, and transfers of their ownership
may be effected only through, records maintained by DTC or its nominee with
respect to interests of participants, and the records of participants with
respect to interests of persons other than participants. DTC currently limits
the maximum denomination of any single global note to $400,000,000.

     So long as DTC or its nominee is the registered owner or holder of the
global notes, DTC or that nominee, as the case may be, will be considered the
sole owner or holder of the debt securities represented by the global notes for
all purposes under the indenture and the debt securities. As a result, no
beneficial owner of an interest in the global notes will be able to transfer
that interest except in accordance with DTC's applicable procedures, in addition
to those provided for under the indenture.

     Payments of the principal of, and interest on, the global notes will be
made to DTC or its nominee, as the case may be, as the registered owner of the
global notes. Neither we, nor 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 notes
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     We expect that DTC or its nominee, upon receipt of any payment of principal
or interest in respect of the global notes, will credit participants' accounts
with payments in amounts proportionate to their respective beneficial interests
in the principal amount of the global notes as shown on the records of DTC or
its nominee. We also expect that payments by participants to owners of
beneficial interests in the global notes held through such participants will be
governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers registered in the names of
nominees for such customers. Such payments will be the responsibility of such
participants.

                                        45


     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC's rules and will be settled in same-day funds. If a
holder requires physical delivery of a certificated note for any reason,
including to sell debt securities to persons in states which require delivery of
certificated notes or to pledge their debt securities, such holder must transfer
its interest in the global notes in accordance with the normal procedures of DTC
and the procedures set forth in the indenture.

     DTC has advised us that it will take any action permitted to be taken by a
holder of a series of debt securities (including the presentation of debt
securities for exchange as described below) only at the direction of one or more
participants to whose account the DTC interests in the global notes relating to
such series is credited and only in respect of such portion of the aggregate
principal amount of debt securities as to which such participant or participants
has or have given such direction. However, if there is an event of default under
a series of debt securities, DTC will exchange the global notes relating to such
series for certificated notes which it will distribute to its participants.

     DTC has advised us as follows: DTC is a limited purpose trust company
organized under the laws of the state of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Securities Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical movement
of certificates. Participants include securities brokers and dealers, banks,
trust companies and clearing corporations and certain other organizations.
Indirect access to the DTC system is available to "indirect participants" such
as banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a participant, either directly or indirectly.

     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interest in the global notes among participants of DTC, it is under
no obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. Neither we nor the trustee will have
any responsibility for the performance by DTC or its respective participants or
indirect participants of their respective obligations under the rules and
procedures governing their operations.

CERTIFICATED NOTES

     With respect to a series of debt securities, if DTC is at any time
unwilling or unable to continue as a depositary for the global notes and a
successor depositary is not appointed by us within 90 days, if an event of
default has occurred and is continuing, or if we otherwise choose to issue
definitive debt securities, we will issue certificated notes in exchange for the
global notes of such series. In each instance, an owner of a beneficial interest
in a global note will be entitled to have debt securities equal in principal
amount to its beneficial interest registered in its name and will be entitled to
physical delivery of debt securities in definitive form. Debt securities in
definitive form will be issued in denominations as specified in the applicable
prospectus supplement and will be issued in registered form only, without
coupons. We will maintain in the Borough of Manhattan, The City of New York, one
or more offices or agencies where debt securities may be presented for payment
and may be transferred or exchanged. You will not be charged a fee for any
transfer or exchange of your debt securities, but we may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

SAME-DAY SETTLEMENT IN RESPECT OF GLOBAL NOTES

     Global notes held by DTC will trade in DTC's Same-Day Funds Settlement
System until maturity and secondary market trading activity in the debt
securities will settle in immediately available funds. No assurance can be given
as to the effect, if any, of settlement in immediately available funds on the
trading activity in the debt securities.

                                        46


                              PLAN OF DISTRIBUTION

     We may sell the securities separately or together:

     - through one or more underwriters or dealers in a public offering and sale
       by them;

     - directly to investors; or

     - through agents.

     We may sell the securities from time to time in one or more transactions at
a fixed price or prices, which may be changed from time to time:

     - at market prices prevailing at the times of sale;

     - at prices related to such prevailing market prices; or

     - at negotiated prices.

     We will set forth in a prospectus supplement the terms of the offering of
securities, including:

     - the name or names of any agents or underwriters;

     - the purchase price of the securities being offered and the proceeds we
       will receive from the sale;

     - any over-allotment options under which underwriters may purchase
       additional securities from us;

     - any agency fees or underwriting discounts and other items constituting
       agents' or underwriters' compensation;

     - any initial public offering price;

     - any discounts or concessions allowed or reallowed or paid to dealers; and

     - any securities exchanges on which such securities may be listed.

     If we use underwriters for a sale of securities, the underwriters will
acquire the securities for their own account. The underwriters may resell the
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 obligations of the underwriters to purchase the securities will be subject
to the conditions set forth in the applicable underwriting agreement. The
underwriters will be obligated to purchase all the securities of the series
offered if they purchase any of the securities of that series. We may use
underwriters with whom we have a material relationship. We will describe in the
prospectus supplement naming the underwriter the nature of any such
relationship.

     Underwriters, dealers or agents may receive compensation in the form of
discounts, concessions or commissions from us or our purchasers (as their agents
in connection with the sale of securities). These underwriters, dealers or
agents will be considered to be underwriters under the Securities Act. As a
result, discounts, commissions or profits on resale received by the
underwriters, dealers or agents may be treated as underwriting discounts and
commissions. The prospectus supplement will identify any such underwriter,
dealer or agent, and describe any compensation received by them from us. Any
initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.

     We may authorize agents or underwriters to solicit offers by certain types
of institutional investors to purchase securities from us at the public offering
price set forth in the prospectus supplement pursuant to delayed delivery
contracts providing for payment and delivery on a specified date in the future.
We will describe the conditions to these contracts and the commissions we must
pay for solicitation of these contracts in the prospectus supplement.

     Underwriters, dealers and agents may be entitled to indemnification by us
against certain civil liabilities, including liabilities under the Securities
Act, or to contribution with respect to payments made by the underwriters,
dealers or agents, under agreements between us and the underwriters, dealers and
agents.
                                        47


     We may grant underwriters who participate in the distribution of securities
an option to purchase additional securities to cover over-allotments, if any, in
connection with the distribution.

     All securities will be new issues of securities with no established trading
market. Underwriters involved in the public offering and sale of such securities
may make a market in the such securities. However, they are not obligated to
make a market and may discontinue market-making activity at any time. No
assurance can be given as to the liquidity of the trading market for any such
securities.

     Underwriters or agents and their associates may be customers of, engage in
transactions with or perform services for us in the ordinary course of business.

     Any underwriter may engage in overallotment, stabilizing transactions,
short covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act. Overallotment involves sales in excess of the
offering size, which create a short position. Stabilizing transactions permit
bids to purchase the underlying security so long as the stabilizing bids do not
exceed a specified maximum. Short covering transactions involve purchases of the
securities in the open market after the distribution is completed to cover short
positions. Penalty bids permit the underwriters to reclaim a selling concession
from a dealer when the securities originally sold by the dealer are purchased in
a covering transaction to cover short positions. Those activities may cause the
price of the securities to be higher than it would otherwise be. If commenced,
the underwriters may discontinue any of the activities at any time.

     Any underwriters who are qualified market makers on the Nasdaq National
Market may engage in passive market making transactions in the securities on the
Nasdaq National Market in accordance with Rule 103 of Regulation M, during the
business day prior to the pricing of the offering, before the commencement of
offers or sales of the securities. Passive market makers must comply with
applicable volume and price limitations and must be identified as passive market
makers. In general, a passive market maker must display its bid at a price not
in excess of the highest independent bid for such security; if all independent
bids are lowered below the passive market maker's bid, however, the passive
market maker's bid must then be lowered when certain purchase limits are
exceeded.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Pursuant to Article VI, Section 2 of the bylaws of Trustmark, the
corporation may indemnify or reimburse the expenses of any person against all
reasonable expenses incurred in connection with any litigation or proceeding in
which such person may have been involved because he is or was a director
(including honorary or advisory directors) officer or employee of the
corporation or of any other firm, corporation or organization which he served in
any such capacity at the request of Trustmark. Provided, such person shall have
no right to indemnification or reimbursement in relation to any matters in which
he is finally adjudged to have been guilty of or liable for negligence or
willful misconduct in the performance of his duties; and, provided further, that
no person shall be so indemnified or reimbursed in relation to any
administrative proceeding or action instituted by any appropriate bank
regulatory agency which proceeding or action results in a final order assessing
civil monetary penalties or requiring affirmative action by an individual or
individuals in the form of payments to the corporation.

     In addition, pursuant to the Mississippi Business Corporations Act,
directors and officers are entitled to indemnification if they are wholly
successful, on the merits or otherwise, in the defense of any proceeding to
which such person is a party because he was a director or officer of the
corporation against reasonable expenses incurred by him in connection with the
proceeding. A corporation may indemnify an individual who is a party to a
proceeding because he is or was a director or officer against a liability
incurred in the proceeding if the person conducted himself in good faith and he
reasonably believed, in the case of conduct in his official capacity, that his
conduct was in the best interests of the corporation, and, in all other cases,
that his conduct was not opposed to the best interests of the corporation, and,
in the case of any criminal proceeding, that he had no reasonable cause to
believe his conduct was unlawful or, he engaged in conduct for which broader
indemnification has been made permissible or obligatory under a provision of the
corporation's articles of incorporation. Unless ordered by a court, a
corporation may not indemnify a director or officer in connection with a
proceeding by or in the right of the corporation, except for reasonable expenses
incurred in connection with the proceeding if it is determined that the director
has met the relevant standard of conduct specified above, or, in connection with
any proceeding with respect to conduct for which he was adjudged liable on the
basis that he received a financial benefit to which he was not entitled, whether
or not involving action in his official capacity.

     A corporation may, additionally, before final disposition of a proceeding,
advance funds to pay for or reimburse the reasonable expenses incurred by the
director or officer who is a party to a proceeding under certain circumstances.

ITEM 17.  UNDERTAKINGS

     The undersigned registrants hereby undertake:

          (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 any 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 percent 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 the registration statement
        or any material change to such information in the registration
        statement;

     provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if
     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 15(d) of the Securities Exchange Act of 1934 that
     are incorporated by reference in the registration statement.

                                       II-3


          (2)  That, for the purpose of determining any liability under the
     Securities Act of 1933, each post-effective amendment shall be deemed to be
     a new registration statement relating to the securities it offers, and the
     offering of the securities at that time shall be deemed to be the initial
     bona fide offering thereof.

          (3)  To remove from registration by means of post-effective amendment
     any of the securities being registered that remain unsold at the
     termination of this offering.

          (4)  If the registrant is a foreign private issuer, to file a
     post-effective amendment to the registration statement to include any
     financial statements required by Item 8.A. of Form 20-F at the start of any
     delayed offering or throughout a continuous offering. Financial statements
     and information otherwise required by Section 10(a)(3) of the Securities
     Act of 1933, need not be furnished, provided, that the Registrant includes
     in the prospectus, by means of a post-effective amendment, financial
     statements required pursuant to this paragraph (4) and other information
     necessary to ensure that all other information in the prospectus is at
     least as current as the date of those financial statements. Notwithstanding
     the foregoing, with respect to registration statements on Form F-3, a
     post-effective amendment need not be filed to include financial statements
     and information required by Section 10(a)(3) of the Securities Act of 1933
     or Rule 3-19 of Regulation S-X if such financial statements and information
     are contained in periodic reports filed with or furnished to the Commission
     by the registrant pursuant to Section 13 or Section 15(d) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the Form F-3.

          (5)  That, 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 of 1933 shall be deemed
     to be part of this registration statement as of the time it was declared
     effective.

          (6)  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 therein, and the offering of the securities at that time shall be
     deemed to be the initial bona fide offering thereof.

          (7)  To file an application for the purpose of determining the
     eligibility of any trustee to act under subsection (a) of Section 310 of
     the Trust Indenture Act in accordance with the rules and regulations
     prescribed by the Commission under Section 305(b)(2) of the Trust Indenture
     Act.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrants pursuant to the foregoing provisions, or otherwise, the registrants
have been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrants of expenses incurred or
paid by a director, officer or controlling person of the registrants 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 registrants 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 of 1933 and will be
governed by the final adjudication of such issue.

                                       II-4
