     Pooling and Servicing Agreement of Registrant dated as of November 1, 1988
     (hereby incorporated herein by reference as part of the Registrant's
     Current Report on Form 8-K filed with Securities and Exchange Commission
     on February 9, 1999).

     Documents in Part II and Part IV incorporated herein by reference
     are as follows:

     Monthly Remittance Statement to the Certificateholders as to distributions
     made on December 27, 1988, and filed with the Securities and Exchange
     Commission on Form 8-K on February 9, 1999.


     PART I

     ITEM 1.  Business.

     The trust fund relating to Pooling and Servicing Agreement dated as of
     November 1, 1988 (the "Pooling and Servicing Agreement") among First
     Boston Mortgage Securities Corp., as Depositor (the "Depositor"),
     Ameristar Financial Corporation as master servicer, (the "Master
     "Servicer"), and Security Pacific National Bank, as trustee (the
     "Trustee").

     The Conduit Mortgage Pass-Through Certificates, Series 1988-3 will be
     comprised of Class A Certificates and Class B Certificates, which will
     consist of two subclasses, the Class B-1 Certificates and the Class B-2
     Certificates (collectively, the "Certificates").  The Class A Certificates
     and the Class B Certificates will represent interests in the Master Trust
     Fund described in the Prospectus Supplement dated October 19, 1988 which
     consists of Subsidiary Regular Interests (as defined in the Prospectus
     Supplement) which in the aggregate represent an interest in a pool (the
     "Mortgage Pool") of adjustable rate, conventional mortgage loans secured
     by first mortgages or deeds of trust on one- to four- unit residential
     properties (the "Mortgage Loans") originated or acquired by AmeriStar
     Financial Corporation ("AmeriStar"), and certain other property held in
     trust for the benefit of the Certificateholders.  The Mortgage Loans will
     be sold to First Boston Mortgage Securities Corp. (the "Depositor") on or
     prior to the date of initial issuance of the Certificates and will be
     transferred to a trust pursuant to the Pooling and Servicing Agreement
     dated as of November 1, 1988 by the Depositor in exchange for the
     Certificates.  AmeriStar will act as Master Servicer.

     The Class A Certificates will evidence an initial interest of
     approximately 90.90% in the Mortgage Loans.  The remaining interest in the
     Mortgage Loans will be evidenced by the Class B Certificates.  The rights
     of the Class B Certificateholders to receive distributions with respect to
     the Mortgage Loans are subordinated to the rights of the Class A
     Certificateholders to the extent described in the Prospectus Supplement
     and in the Prospectus.  In addition, the Class A Certificateholders will
     be entitled to receive a disproportionately greater percentage of
     Principal Prepayments and other payments with respect to the Mortgage
     Loans, as described in the Prospectus Supplement.  See "Description of the
     Certificates- Distributions" and "-Subordination of the Class B
     Certificates; Shifting Interest Credit Enhancement" in the Prospectus
     Supplement and "Credit Support- Subordinated Certificates" in the
     Prospectus.

     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 1988-3, 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 1988-3 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 June 2, 1989 was 1.

     (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 December 27, 1988, and filed with the Securities and Exchange
     Commission on Form 8-K on February 9, 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 June 2, 1989, 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:

	Banque Paribas Grand Cayman
	Banque Paribas New York
	Attn:  Carlos R. Torres
	787 Seventh Avenue, 33rd Floor
	New York, NY  10019
	Series 1988-3
	Class A
	$6,000,000.0
	100.0%

     (b)  Security ownership of management.  Not Applicable.  The Trust does
     not have any officers or directors.  Therefore, the information required
     by Item 403 of Regulation S-K is inapplicable.

     (c)  Changes in control.  Not Applicable.  Since Certificateholders do not
     possess, directly or indirectly, the power to direct or cause the
     direction of the management and policies of the Trust, other than in
     respect to certain required consents regarding any amendments to the
     Pooling and Servicing Agreement, the information requested with respect to
     item 403 of Regulation S-K is inapplicable.

     ITEM 13.  Certain Relationships and Related Transactions.

     (a)  Transactions with management and others.  Depositor knows of no
     transaction or series of transactions during the fiscal year ended
     December 31, 1988, or any currently proposed transaction or series of
     transactions, in an amount exceeding $60,000 involving the Depositor in
     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
     described in Item 404(a)(1),(2) and (4) of Regulation S-K, however, the
     information required by Item 404(a)(3) of Regulation S-K is hereby
     incorporated by reference in Item 12 herein.

     (b)  Certain business relationships.  None.

     (c)  Indebtedness of management. Not Applicable.  The Trust does not have
     management consisting of any officers or directors.  Therefore, the
     information required by item 404 of Regulation S-K is inapplicable.

     (d)  Transactions with promoters.  Not Applicable.  The Trust does not
     use promoters.  Therefore, the information required by item 404 of
     Regulation S-K is inapplicable.
