                    CAPTEC FRANCHISE CAPITAL PARTNERS L.P. IV
                          NOTES TO FINANCIAL STATEMENTS



1.       THE PARTNERSHIP AND ITS SIGNIFICANT ACCOUNTING PRINCIPLES:

         Captec Franchise Capital Partners L.P. IV (the "Partnership"), a
         Delaware limited partnership, was formed on July 23, 1996 for the
         purpose of acquiring income-producing commercial real properties and
         equipment leased on a "triple net" or "double net" basis, primarily to
         operators of national and regional chain and nationally franchised fast
         food and family style restaurants, as well as other national and
         regional retail chains. The general partners of the Partnership upon
         formation of the Partnership were Captec Franchise Capital Corporation
         IV (the "Corporation"), a wholly owned subsidiary of Captec Financial
         Group, Inc. ("Captec"), and Patrick L. Beach, an individual,
         hereinafter collectively referred to as the Sponsor. Patrick L. Beach
         is also the Chairman of the Board of Directors, President and Chief
         Executive Officer of the Corporation and Captec. In August, 1998 the
         general partnership interest of the Partnership was acquired by Captec
         Net Lease Realty, Inc., an affiliate of Captec, for $2,912,000.

         The Partnership commenced a public offering of limited partnership
         interest units on December 23, 1996. A maximum of 30,000 units, priced
         at $1,000 per unit, were offered on a "best efforts, part or none"
         basis. The Partnership broke impound on March 5, 1997, and the
         Partnership immediately commenced operations. The Partnership completed
         the sale of all 30,000 units in 1998. On April 1, 1999 the Partnership
         repurchased a total of 2.86 units for $2,570.64, or 90% of the
         investor's capital account. An additional 114 units were repurchased on
         October 1, 1999 for $102,828, or 90% of the investor's capital account.
         The repurchase of the units was completed pursuant to the terms of the
         Repurchase Plan set forth in the Partnership's Prospectus. At March 31,
         2000, the Partnership had 29,883 units issued and outstanding.

         Allocation of profits, losses and cash distributions from operations
         and cash distributions from sale or refinancing are made pursuant to
         the terms of the Partnership Agreement. Profits and losses from
         operations are allocated among the limited partners based upon the
         number of units owned.

         The balance sheet of the Partnership as of March 31, 2000 and the
         statements of operations and cash flows for the period ending March 31,
         2000 and 1999 have not been audited. In the opinion of the Management,
         these unaudited financial statements contain all adjustments necessary
         to present fairly the financial position and results of operations and
         cash flows of the Partnership for the periods then ended. Results of
         operations for the interim periods are not necessarily indicative of
         results for the full year. These unaudited financial statements should
         be read in conjunction with the financial statements and notes thereto
         included in the Partnership's annual report on Form 10-K for the year
         ended December 31, 1999 filed with the United States Securities and
         Exchange Commission on March 30, 2000.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS


When used in this discussion, the words, "intends", "anticipates", "expects",
and similar expressions are intended to identify forward-looking statements.
Such statements are subject to certain risks and uncertainties which could cause
actual results to differ materially from those projected. Such risks and
uncertainties include the following: (i) a tenant may default in making rent
payments, (ii) a fire or other casualty may interrupt the cash flow stream from
a property, (iii) the properties may not be able to be leased at the assumed
rental rates, (iv) unexpected expenses may be incurred in the ownership of the
properties, and (v) properties may not be able to be sold at the presently
anticipated prices and times.

As a result of these and other factors, the Partnership may experience material
fluctuations in future operating results on a quarterly or annual basis, which
could materially and adversely affect its business, financial condition and
operating results. These forward-looking statements speak only as of the date
hereof. The Partnership undertakes no obligation to publicly release the results
of any revisions to these forward-looking statements which may be made to
reflect events or circumstances after the date hereof or to reflect the
occurrence of unanticipated events.


RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2000. During the three months ended March 31, 2000
total operating revenue increased 8% to $873,000 as compared to $807,000 for the
three months ended March 31, 1999. Rental revenue from operating leases for the
three months ended March 31, 2000 increased 19% to $720,000 as compared to
$606,000 for the three months ended March 31, 1999 primarily from the benefit of
a full period of rental revenue from properties acquired and leased in
preceeding periods. Earned income from financing leases for the three months
ended March 31, 2000 decreased 24% to $153,000 as compared to $201,000 for the
three months ended March 31, 1999 primarily due to the sale of one equipment
lease.

Operating expenses were approximately $335,000 for the three months ended March
31, 2000 as compared to $238,000 for the three months ended March 31, 1999.
Total operating expenses for the three months ended March 31, 2000 is comprised
of $94,000 of depreciation expense, $27,000 of general and administrative
expenses, and $214,000 of interest expense. The increase in operating expenses
for the three months ended March 31, 2000 as compared to the three months ended
March 31, 1999 is primarily due to additional interest expense related to the
note payable issued in March, 1999, and increased depreciation expense for new
property acquisitions.

Other income for the three months ended March 31, 2000 increased to $42,000 as
compared to $4,000 for the three months ended March 31, 1999 as a result of a
gain on the sale of one equipment lease.

As a result of the foregoing, the Partnership's net income increased 1% to
$580,000 for the three months ended March 31, 2000 as compared to $573,000 for
the three months ended March 31, 1999.

DISTRIBUTIONS. The Partnership announced first quarter distributions of
$900,000, of which $783,089 was distributed to its Limited Partners on April 14,
2000 and the remaining $116,911 will be distributed to those limited partners
who elected to receive distributions on a monthly basis.

LIQUIDITY AND CAPITAL COMMITMENTS

The Partnership commenced the offering of up to 30,000 limited partnership units
registered under the Securities Act of 1933, as amended, by means of a
Registration Statement which was declared effective by the Securities and
Exchange Commission on December 23, 1996. The Offering reached final funding in
December, 1998 with subscriptions for the entire offering of 30,000 units. Net
proceeds after offering expenses were approximately $26.1 million.

In December, 1998 the Partnership entered into a $6.375 million term note. The
Partnership entered into an additional $3.276 million term note in March, 1999.
Proceeds from the notes were used to acquire additional properties. The notes
have a 10-year term, are collaterized by certain properties subject to operating
leases, and bear interest at rates ranging from 8.13 to 8.5% per annum. Debt
issuance costs of approximately $595,500 in aggregate incurred in connection
with the issuance of the notes are being amortized into interest expense over
the life of the notes using the straight-line method.

At March 31, 2000 the Partnership had a portfolio of 20 properties located in 10
states, with a cost of $26.8 million, and 24 equipment leases with an original
investment of $8.5 million. As of March 31, 2000 the Partnership's investments
were allocated approximately 76% to properties and 24% to equipment.

The Partnership expects to require limited amounts of liquid assets since the
properties and equipment leases require the lessees to pay all taxes and
assessments, maintenance and repair items (except, with respect to double net
properties, costs associated with maintenance and repair of the exterior walls
and roof of the property) and insurance premiums, including casualty insurance.
The general partners expect that the cash flow to be generated by the
Partnership's properties and equipment will be adequate to pay operating
expenses and provide distributions to Limited Partners.
