Annual Report (Form 10-K), fiscal year 1993

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.



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.

ITEM 3. Legal Proceedings.
None.
ITEM 4.

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.

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.

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.

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.
