(a)  The consolidated financial statements of Sun Company, Inc. and subsidiaries
     contain the accounts of all subsidiaries that are controlled (generally
     more than 50 percent owned) except those accounted for as investments held
     for sale or discontinued operations. Prior to the fourth quarter of 1993,
     coal and real estate operations were accounted for as discontinued
     operations and, accordingly, were excluded from the computation of the
     ratio of earnings to fixed charges. Effective in the fourth quarter of
     1993, coal and real estate operations and their results of operations are
     now included in continuing operations. Accordingly, beginning October 1,
     1993, coal and real estate operations are included in the computation of
     the ratio of earnings to fixed charges. (See Note 2 to the consolidated
     financial statements in the Company's 1995 Annual Report to Shareholders.)
     Affiliated companies over which the Company has the ability to exercise
     significant influence but that are not controlled (generally 20 to 50
     percent owned) are accounted for by the equity method.
(b)  Represents one-third of total operating lease rental expense which is that
     portion deemed to be interest.
