                                     PART I
ITEM 1.   BUSINESS

         The Discover Card Trust 1993 B (the "Trust") was formed pursuant to a
Pooling and Servicing Agreement dated as of February 1, 1993 (the "Pooling and
Servicing Agreement") among Greenwood Trust Company ("Greenwood") as Servicer,
Discover Receivables Financing Group, Inc. ("DRFG") as Seller, and Wilmington
Trust Company as Trustee (the "Trustee"). The Trust's only business is to act as
a passive conduit to permit investment in a pool of retail consumer receivables.

ITEM 2.   PROPERTIES

         The property of the Trust includes a portfolio of receivables (the
"Receivables") arising under selected Discover Card accounts (the "Accounts")
originated by Greenwood, all monies due or to become due in payment of the
Receivables, all proceeds of the Receivables, all monies on deposit in certain
accounts and a certain limited credit enhancement for the exclusive direct
benefit of holders of 7.10% Class B Credit Card Pass-Through Certificates of the
Trust (the "Class B Certificates"). At or prior to the time of the Trust's
formation, Sears, Roebuck and Co. ("Sears") sold or contributed to DRFG
Receivables existing under the Accounts as of February 1, 1993 and theretofore
acquired by Sears from Greenwood; SCFC Receivables Corp. ("SRC") sold or
contributed to DRFG Receivables existing under the Accounts as of February 1,
1993 and theretofore acquired by SRC from Greenwood; and Greenwood sold to DRFG,
all other Receivables existing under the Accounts as of February 1, 1993 and all
Receivables existing under the Accounts from time to time thereafter. DRFG, in
turn, transferred to the Trust all Receivables existing under the Accounts as of
February 1, 1993 and all Receivables arising under the Accounts from time to
time thereafter until the termination of the Trust. Information related to the
performance of the Receivables during the period from December 1, 1998 through
November 30, 1999 is set forth in the ANNUAL AGGREGATE REPORT filed as Exhibit
99(A) to this Annual Report on Form 10-K.

ITEM 3.   LEGAL PROCEEDINGS

         Greenwood is involved from time to time in various legal proceedings
that arise in the ordinary course of its business. Greenwood does not believe
that the resolution of any of these proceedings will have a material adverse
effect on Greenwood's financial condition or on the Receivables. There can be no
assurance, however, regarding any of these effects.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

          None


                                     PART II

ITEM 5.   MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

         The Class B Certificates are held and delivered in book-entry form
through the facilities of The Depository Trust Company ("DTC"), a "clearing
agency" registered pursuant to

the provisions of Section 17A of the Securities Exchange Act of 1934, as

         As of February 23, 2000, 100% of the Class B Certificates was held in
the nominee name Cede & Co. for beneficial owners.

         As of February 23, 2000, Greenwood and DRFG, as tenants-in-common,
owned 100% of the uncertificated Seller Certificate, which represented
beneficial ownership of a residual interest in the assets of the Trust as
provided in the Pooling and Servicing Agreement.

ITEM 13.   CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
