                               SECOND AMENDMENT TO
                        REVOLVING SUBORDINATION AGREEMENT



This Second Amendment to Revolving Subordinated Loan Agreement ("this Second
Amendment") is made and entered into by and between The Charles Schwab
Corporation (the "Lender") and Charles Schwab & Co., Inc. (the "Organization")
as of this 1st day of November, 1991. Unless otherwise specified herein, all
capitalized terms used herein shall have the meanings ascribed to them in
Revolving Subordinated Loan Agreement dated as of September 29, 1988, as amended
by a First Amendment thereto dated as of April 18, 1990, both between the Lender
and the Organization (collectively, the "Agreement").

WHEREAS, the Organization and the Lender desire to amend the Agreement to
decrease the permissible aggregate principle amount of loans outstanding at any
one time from $205,000,000 to $180,000,000.

NOW, THEREFORE, the Organization and the Lender hereby amend the Agreement as
follows:

         1.       The figure "$180 million" shall be and hereby is substituted
                  in place of the figure "$205 million" in the second paragraph
                  of paragraph "1." of the Agreement.

         2.       Contemporaneously with the execution hereof, the Organization
                  shall execute and deliver to the Lender a new promissory note
                  in the form attached hereto as Exhibit A (the "new Revolving
                  Note"), which new Revolving Note shall replace and supersede
                  the Revolving Note dated April 18, 1990 made and delivered by
                  the Organization to the Lender.

         3.       Contemporaneously with the execution hereof, the Lender and
                  the Organization shall execute a Roll-Over Attachment in the
                  form attached hereto as Exhibit B (the "Roll-Over
                  Attachment"), pursuant to which the Lender and the
                  Organization agree the Commitment Termination Date and the
                  Scheduled Maturity Date shall in each year, without further
                  action by either the Lender or the Organization, be extended
                  to September 29 of the following year, unless on or before
                  the day twelve month preceding the Scheduled Maturity Date
                  then in effect, the Lender shall notify the Organization in
                  writing, with a written copy to the New York Stock Exchange,
                  Inc., that the Commitment Termination Date and the Scheduled
                  Maturity Date then in effect shall not be extended. The
                  Roll-Over Attachment shall become part of the Agreement as
                  amended by this Second Amendment.


                                       1
   2
         4.       Except for the amendment, expressly specified above, all other
                  provisions of the Agreement remain in full force and effect.

IN WITNESS WHEREOF, the Second Amendment is executed as of November 1, 1991 at
San Francisco, California.
