                                     PART I

ITEM 1. THE COMPANY.

CMC Securities Corporation II (the "Company") was incorporated in Delaware on
January 4, 1993 as a limited-purpose finance corporation and is wholly-owned by
Capstead Holdings, Inc. ("CHI"), a subsidiary of Capstead Mortgage Corporation
("CMC"). CHI was formed in 1997 in part to hold CMC's interest in the Company
and Capstead Inc. Prior to the formation of CHI, the Company was owned by
Capstead Inc. The Company is managed by CMC (the "Manager").

The Company was formed primarily for the purpose of issuing publicly-offered
multi-class, mortgage pass-through certificates ("MPCs") that evidence ownership
interests in trust funds owning pools of mortgage loans secured by single-family
residences purchased by the trust funds from the Company. On March 30, 1993 the
Securities and Exchange Commission declared effective an amended registration
statement filed by the Company covering the offering of a maximum of $2 billion
aggregate principal amount of MPCs, issuable from time to time in series.
Another registration statement became effective September 27, 1993 covering the
offering of another $2 billion of MPCs. The Company issued its first MPC (MPC
series 1993-2A) on May 28, 1993. As of December 31, 2001, the Company had issued
13 MPCs (MPC Series 1993-2A through 1996-C) totaling $2,960,389,000, including
$217,199,000 of privately-placed MPCs.

COMPETITION

In issuing securities, the Company competes with other issuers of these
securities and the securities themselves compete with other investment
opportunities available to prospective purchasers.

EMPLOYEES

The Manager provides all executive and administrative personnel required by the
Company.

MANAGEMENT AGREEMENT

Pursuant to a Management Agreement, the Manager advises the Company with respect
to its investments and administers the day-to-day operations of the Company. The
Management Agreement is nonassignable except by consent of the Company and the
Manager. The Management Agreement may be terminated without cause at any time
upon 90 days written notice. In addition, the Company has the right to terminate
the Management Agreement upon the happening of certain specified events,
including a breach by the Manager of any provision contained in the Management
Agreement which remains uncured for 30 days after notice of such breach and the
bankruptcy or insolvency of the Manager.

The Manager is at all times subject to the supervision of the Company's Board of
Directors and has only such functions and authority as the Company delegates to
it. The Manager is responsible for the day-to-day operations of the Company and
performs such services and activities relating to the assets and operations of
the Company as may be appropriate. The Manager receives an annual basic
management fee of $10,000 per year for managing the assets pledged to secure
Bonds issued by the Company.

The Manager is required to pay employment expenses of its personnel (including
salaries, wages, payroll taxes, insurance, fidelity bonds, temporary help and
cost of employee benefit plans), and other office expenses, travel and other
expenses of directors, officers and employees of the Manager, accounting fees
and expenses incurred in supervising and monitoring the Company's investments.
The Company is required to pay all other expenses of operation (as defined in
the Management Agreement).


                                      -1-
<PAGE>


ITEM 2. PROPERTIES.

The Company conducts operations at CMC's offices in Dallas, Texas.

Each series of MPCs issued by the Company represents in the aggregate the entire
beneficial interest in a trust (collectively, for all such series, the "Trusts")
consisting primarily of a segregated pool of single-family first mortgage loans.
For each servicer of mortgage loans owned by the Trusts, the Company will
furnish an Officer's Certificate of the Servicer with regard to such servicer's
compliance with the terms of the Security Agreement.

Listing of Officer's Certificates of the Servicers............. See Exhibit 99.3

ITEM 3. LEGAL PROCEEDINGS.

As of the date hereof, there are no material legal proceedings outside the
normal course of business to which the Company was a party or of which any of
its property was the subject.

                                     PART II

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

All of the Company's common stock is owned by CHI. Accordingly, there is no
public trading market for its common stock. Presently, there is no established
trading market for the Company's MPCs. Holders of record for the Company's
publicly-offered MPCs are as follows:
