     PART I

     ITEM 1.  Business.

     The trust fund relating to Pooling and Servicing Agreement dated as of
     July 1, 1993 (the "Pooling and Servicing Agreement") between First Boston
     Mortgage Securities Corp., depositor (the "Depositor"), Countrywide
     Funding Corporation as master servicer (the "Master Servicer") and Bankers
     Trust Company of California, N.A. as trustee (the "Trustee").

     The Conduit Mortgage Pass-Through Certificates, Series 1993-5 (the
     "Certificates") will be comprised of Interest-Only Class X, Principal Only
     Class P, Classes A-1 through A-15, Class A-R, Class M-1, Class M-2, Class
     B-1, Class B-2, and the Subordinated Class B-3, Class B-4 and Class B-5
     Certificates (collectively with the Class B-1 and Class B-2 Certificates,
     the "Class B Certificates").  It is a condition to their issuance that the
     Class X, Class P, Class A-1 through Class A-15 and Class A-R
     (collectively, the "Class A Certificates") and Class M-1 Certificates be
     rated "AAA" by Fitch Investors Service, Inc. ("Fitch") and "Aaa" by
     Moody's Investors Service, Inc. ("Moody's"), that the Class M-2
     Certificates be rated "AA" by Fitch, that the Class B-1 Certificates be
     rated "A" by Fitch and that the Class B-2 Certificates be rated "BBB" by
     Fitch.  Accordingly, the Class B-1 and Class B-2 Certificates will not
     constitute "mortgage related securities" for purposes of the Secondary
     Mortgage Market Enhancement Act of 1984, as amended.

     The Certificates evidence beneficial ownership interests in a trust fund
     (the "Trust Fund") to be created by First Boston Mortgage Securities Corp.
     (the "Depositor"), which will consist primarily of a pool of conventional
     30-year, fully-amortizing, fixed-rate mortgage loans (the "Mortgage
     Loans") secured by first liens on one- to four- family, residential real
     properties.  The Mortgage Loans were originated by or acquired by
     Countrywide Funding Corporation ("Countrywide") and will be purchased by
     the Depositor from First Boston Mortgage Capital Corp., an affiliate of
     the Depositor.  The Mortgage Loans are more fully described under
     "Description of the Mortgage Pool and the Underlying Mortgaged Properties"
     in the Prospectus Supplement dated July 22, 1993.

     Information with respect to the business of the Trust would not be
     meaningful because the only "business" of the Trust is the collection on
     the Mortgage Loans and distribution of payments on the Certificates to
     Certificateholders. This information is accurately summarized in the
     Monthly Reports to Certificateholders, which are filed on Form 8-K.  There
     is no additional relevant information to report in response to Item 101 of
     Regulation S-K.

     ITEM 2.  Properties.

     The Depositor owns no property.  The First Boston Mortgage Securities
     Corp., Conduit Mortgage Pass-Through Certificates, Series 1993-5, in the
     aggregate, represent the beneficial ownership in a Trust consisting
     primarily of the Mortgage Loans.  The Trust will acquire title to real
     estate only upon default of the mortgagors under the Mortgage Loan.
     Therefore, this item is inapplicable.

     ITEM 3.  Legal Proceedings.

     None.

     ITEM 4.  Submission of Matters to a Vote of Security Holders.

     No matters were submitted to a vote of Certificateholders during the
     fiscal year covered by this report.


     PART II

     ITEM 5.  Market for Depositor's Common Equity and Related Stockholder
     Matters.

     The First Boston Mortgage Securities Corp., Conduit Mortgage Pass-Through
     Certificates, Series 1993-5 represent, in the aggregate, the beneficial
     ownership in a trust fund consisting primarily of the Mortgage Loans.
     The Certificates are owned by Certificateholders as trust beneficiaries.
     Strictly speaking, Depositor has no "common equity," but for purposes of
     this Item only, Depositor's Conduit Mortgage Pass-Through Certificates
     are treated as "common equity."

     (a)  Market Information.  There is no established public trading market
     for Depositor's Notes.  Depositor believes the Notes are traded
     primarily in intra-dealer markets and non-centralized inter-dealer
     markets.

     (b)  Holders.  The number of registered holders of all classes of
     Certificates on (for dates see ITEM 12(a)) was 29.

     (c)  Dividends.  Not applicable.  The information regarding dividend
     required by sub-paragraph (c) of Item 201 of Regulation S-K is
     inapplicable because the Trust does not pay dividends.  However,
     information as to distribution to Certificateholders is provided in the
     Monthly Reports to Certificateholders for each month of the fiscal year in
     which a distribution to Certificateholders was made.

     ITEM 6.  Selected Financial Data.

     Not Applicable.  Because of the limited activities of the Trust, the
     Selected Financial Data required by Item 301 of Regulation S-K does not
     add relevant information to that provided by the Monthly Reports to
     Certificateholders, which are filed on a monthly basis on Form 8-K.

     ITEM 7.  Management's Discussion and Analysis of Financial Condition and
     Results of Operations.

     Not Applicable.  The information required by Item 303 of Regulation S-K
     is inapplicable because the Trust does not have management per se, but
     rather the Trust has a Trustee who causes the preparation of the Monthly
     Reports to Certificateholders.  The information provided by the Monthly
     Reports to Certificateholders, which are filed on a monthly basis on Form
     8-K, does provide the relevant financial information regarding the
     financial status of the Trust.

     ITEM 8.  Financial Statements and Supplementary Data.

     Monthly Remittance Statement to the Certificateholders as to distributions
     made on August 25, 1993, and filed with the Securities and Exchange
     Commission on Form 8-K on February 10, 1999.

     Monthly Remittance Statement to the Certificateholders as to distributions
     made on September 27, 1993, and filed with the Securities and Exchange
     Commission on Form 8-K on February 10, 1999.

     Monthly Remittance Statement to the Certificateholders as to distributions
     made on October 25, 1993, and filed with the Securities and Exchange
     Commission on Form 8-K on February 10, 1999.

     Monthly Remittance Statement to the Certificateholders as to distributions
     made on November 26, 1993, and filed with the Securities and Exchange
     Commission on Form 8-K on February 10, 1999.

     Monthly Remittance Statement to the Certificateholders as to distributions
     made on December 27, 1993, and filed with the Securities and Exchange
     Commission on Form 8-K on February 10, 1999.

     Annual Statement of Compliance by the Master Servicer is not
     currently available and will be subsequently filed on Form 8.

     Independent Accountant's Report on Servicer's will be subsequently filed
     on Form 8.

     ITEM 9.  Changes in and Disagreements with Accountants on Accounting and
     Financial Disclosure.

     None.


     PART III

     ITEM 10.  Directors and Executive Officers of Depositor.

     Not Applicable.  The Trust does not have officers or directors.
     Therefore, the information required by items 401 and 405 of Regulation S-K
     are inapplicable.

     ITEM 11.  Executive Compensation.

     Not Applicable.  The Trust does not have officers or directors to whom
     compensation needs to be paid.  Therefore, the information required by
     item 402 of regulation S-K is inapplicable.

     ITEM 12.  Security Ownership of Certain Beneficial Owners and
     Management.

     (a)  Security ownership of certain beneficial owners.  Under the
     Pooling and Servicing Agreement governing the Trust, the holders of the
     Certificates generally do not have the right to vote and are prohibited
     from taking part in management of the Trust.  For purposes of this Item
     and Item 13 only, however, the Certificateholders are treated as "voting
     security" holders.

      As of the dates indicated below, the following are the only persons known
      to the Depositor to be the beneficial owners of more than 5% of
      any class of voting securities:

     which the Certificateholders identified in Item 12(a) had or will have a
     direct or indirect material interest.  There are no persons of the types
