This Amendment No. 5 (this "Amendment") amends and supplements the Statement on
Schedule 13D, as heretofore amended (the "Schedule 13D"), relating to the shares
of common stock, no par value (the "Shares"), of Trustmark Corporation, a
Mississippi corporation (the "Issuer"), previously filed by Robert M. Hearin
Support Foundation, The Robert M. Hearin Foundation, and Capitol Street
Corporation (each a Reporting Person and, collectively, the "Reporting
Persons").  This Amendment is being filed to update the Schedule 13D in light of
the change in the Reporting Persons' ownership percentage of the Shares caused
primarily by the Issuer's repurchases of Shares in recent years.  The Amendment
also updates certain changes in the facts reported in the Schedule 13D, none of
which, individually or in the aggregate, the Reporting Persons believe to be
material.  In this Amendment, Galaxie Corporation, which has been identified in
the Schedule 13D as the sole shareholder of Capitol Street Corporation, has been
added as a Reporting Person.  This change does not reflect any change in the
relationship between Galaxie Corporation and Capitol Street Corporation or the
plans of any Reporting Person with respect to the Issuer's securities.

Support Foundation, The Robert M. Hearin Foundation, and Capitol Street
Corporation (each a Reporting Person and, collectively, the "Reporting
Persons").  This Amendment is being filed to update the Schedule 13D in light of
the change in the Reporting Persons' ownership percentage of the Shares caused
primarily by the Issuer's repurchases of Shares in recent years.  The Amendment
also updates certain changes in the facts reported in the Schedule 13D, none of
which, individually or in the aggregate, the Reporting Persons believe to be
material.  In this Amendment, Galaxie Corporation, which has been identified in
the Schedule 13D as the sole shareholder of Capitol Street Corporation, has been
added as a Reporting Person.  This change does not reflect any change in the
relationship between Galaxie Corporation and Capitol Street Corporation or the
plans of any Reporting Person with respect to the Issuer's securities.

relationship between Galaxie Corporation and Capitol Street Corporation or the

This Amendment No. 5 (this "Amendment") amends and supplements the Statement on
Schedule 13D, as heretofore amended (the "Schedule 13D"), relating to the shares
of common stock, no par value (the "Shares"), of Trustmark Corporation, a
Mississippi corporation (the "Issuer"), previously filed by Robert M. Hearin
Support Foundation, The Robert M. Hearin Foundation, and Capitol Street
Corporation (each a Reporting Person and, collectively, the "Reporting
Persons").  This Amendment is being filed to update the Schedule 13D in light of
the change in the Reporting Persons' ownership percentage of the Shares caused
primarily by the Issuer's repurchases of Shares in recent years.  The Amendment
also updates certain changes in the facts reported in the Schedule 13D, none of
which, individually or in the aggregate, the Reporting Persons believe to be
material.  In this Amendment, Galaxie Corporation, which has been identified in
the Schedule 13D as the sole shareholder of Capitol Street Corporation, has been
added as a Reporting Person.  This change does not reflect any change in the
relationship between Galaxie Corporation and Capitol Street Corporation or the
plans of any Reporting Person with respect to the Issuer's securities.
