purposes.

The Notes will be general senior unsecured obligations of the Company and will
rank PARI PASSU in right of payment with all existing and future unsecured and
unsubordinated indebtedness of the Company and senior in right of payment to any
subordinated indebtedness of the Company. The Notes are, unconditionally
guaranteed, on a senior unsecured basis, as to payment of principal, premium if
any, and interest, jointly and severally by the Guarantors which consist of the
Company's Domestic Restricted Subsidiaries, as defined. The Notes will be
redeemable at any time and from time to time at the option of the Company, in
whole or in part on or after August 1, 2002, plus accrued and unpaid interest
thereon to the date of redemption. In addition, on or prior to August 1, 2001,
the Company may redeem, at its option, up to 35% of the aggregate principal
amount at maturity of the Notes with the net proceeds of one or more Equity
Offerings, as defined, at 111.75% of the Accreted Value thereof, as defined, as
long as Notes representing at least $65.0 million of the aggregate initial
Accreted Value of the Notes originally issued remains outstanding after each
such redemption and that such redemption occurs within 90 days of the closing of
any such Equity Offering.

Upon a Change of Control, as defined, the Company will be required to offer to
repurchase the Notes at a purchase price equal to (i) 101% of the Accreted Value
thereof, if the purchase date is on or prior to August 1, 2002, or (ii) 101% of
the principal amount at maturity thereof, plus accrued and unpaid interest
thereon, if any, to the purchase date, if such date is after August 1, 2002.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL
CONDITION
--------------------------------------------------------------------------------

This report contains "forward-looking statements" within the meaning of Section
21E of the Securities Exchange Act of 1934, as amended. These forward-looking
statements include, among others, statements concerning the Company's outlook
for 1998 and beyond, the Company's expectations, beliefs, future plans and
strategies, anticipated events or trends, and similar expressions concerning
matters that are not historical facts. The forward-looking statements in this
report are subject to risks and uncertainties that could cause actual results to
differ materially from those expressed in or implied by the statements. 

OVERVIEW

Radio Unica Corp., incorporated on September 12, 1996 (inception), was organized
for the purpose of producing, broadcasting and distributing Spanish-language
radio programming in the United States. The Company's strategy is to develop its
radio network as a national advertising platform that is attractive to national
advertisers. The network is comprised of owned and operated stations; stations
operated under TBA's and affiliated stations. From inception through the year
ended December 31, 1997, the Company had no revenue and had not commenced
operations. The Company launched its network on January 5, 1998 with 30
affiliated stations and three stations operated under TBAs. The Company expects
to incur operating losses for the foreseeable future as the Company develops its
network and stations and establishes its base of advertising revenues.

The Company generates revenue from sales of network advertising time and sales
of advertising time on the Company-owned stations and stations operated under
TBAs (collectively "O&Os"). Advertising rates are, in large part, based upon
the network's and each station's ability to attract audiences in demographic
groups targeted by advertisers. All revenues are stated net of any agency
commissions.

The Company's operating expenses consist of network programming expenses,
marketing and selling costs, including commissions paid to the Company's sales
staff, technical and engineering costs, and general and administrative expenses.

As is true of other radio operators, the Company's performance is customarily
measured by its earnings before net interest, taxes, depreciation and
amortization ("EBITDA"). Although EBITDA is not a measure of performance
calculated in accordance with generally accepted accounting principles, EBITDA
is presented because it provides useful information regarding the Company's
ability to service debt. However, EBITDA should not be considered as an
alternative measure of operating results or cash flows from operations (as
determined in accordance with generally accepted accounting principles).

RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES

Due to the development nature of the Company, the Company has had negative cash
flows since inception. Working capital and financing for the Company's
acquisitions to date have been provided primarily by the issuance of Promissory
Notes, Company Common Stock and Company Preferred Stock to the Company's
principal shareholder.

The Company's primary sources of liquidity will be the Revolving Credit Facility
and the net proceeds from the 11 3/4% Senior Discount Notes issued on July 27,
1998 (see Note 4 to Financial Statements). The Revolving Credit Facility is a
senior secured revolver with $20.0 million of available borrowings subject to
certain conditions.

Net cash used in operating activities was approximately $8.1 million for the six
months ended June 30, 1998 as compared to approximately $460,000 for the six
months ended June 30, 1997. The increase in cash used in operating activities
during the six month period ended June 30, 1998 is due to the increased costs
associated with the operations of the Company's network and O&Os.

Net cash used in investing activities for the six months ended June 30, 1998 was
approximately $28.3 million as the Company acquired radio stations, funded
escrow accounts related to acquisitions, made investments in and advances to an
equity investee and acquired property and equipment for its O&Os. No cash was
used in investing activities for the comparable period in the prior year.

Capital expenditures primarily related to the purchase of broadcast equipment
for the network and O&Os, leasehold improvements, computer equipment and
telecommunications equipment. For the six months ended June 30, 1998 capital
expenditures were approximately $2.6 million. The Company expects to spend in
the aggregate approximately $2.5 million over the next two years for planned
equipment purchases and for upgrades of existing stations.

Net cash provided by financing activities for the six months ended June 30, 1998
was $36 million as compared to $455,000 for the six months ended June 30, 1997.
The increase in cash provided by financing activities during the six months
ended June 30, 1998 is partially due to additional capital which was raised
through the issuance of preferred and common stock. In addition, the Company
entered into promissory notes payable with WPV of approximately $21.8 million.
The funds were mainly used to acquire radio stations, fund escrow accounts
related to acquisitions, make investments and advances to an equity investee and
acquire property and equipment.

The Company believes that its current cash position and the proceeds from the
issuance of the 11 3/4% Senior Discount Notes on July 27, 1998 and the borrowing
availability under the Revolving Credit Facility will provide adequate resources
to fund the Company's operating expenses, working capital requirements, capital
expenditures and acquisitions until the implementation of its business strategy
provides the Company with sufficient operating cash flow. However, there can be
no assurance that such business strategy will be successfully implemented or
that the future cash flows of the Company will be sufficient to meet all of the
Company's obligations and commitments.

YEAR 2000 COMPLIANCE

The Company is currently assessing its exposure to the Year 2000 issue. All
aspects of the business are under review, including correspondence with vendors,
suppliers and customers regarding their Year 2000 compliance status. Based upon
the results of recent investigation, the Company's primary information and
communications systems are believed to be compliant with Year 2000 requirements.
The Company's cost of compliance has been minimal and any future costs are not
anticipated to be material to financial condition or results of operations.

The Company currently has limited information concerning the Year 2000
compliance status of its suppliers of goods and services, other than those
related to the Company's information systems. In the event that any of the
Company's significant suppliers do not successfully and timely achieve Year 2000
compliance, the Company's business or operations could be adversely affected.
