                                 PROMISSORY NOTE


$1,499,250.00                                                     Miami, Florida
                                                                 January 9, 1996


                  FOR VALUE RECEIVED the undersigned, HBC FLORIDA, INC., a
Delaware corporation ("HBC") and HEFTEL BROADCASTING CORPORATION, a Delaware
corporation ("Heftel") (HBC and Heftel are hereinafter collectively referred to
as "Maker") jointly and severally promise to pay to the order of MAMBISA
BROADCASTING CORPORATION, a Florida corporation, or its successors or assigns
(hereinafter referred to as the "Payee"), at 1790 Coral Way, Suite 200, Miami,
Florida 33145 or such other place as the holder hereof may from time to time
designate in writing, the principal sum of ONE MILLION FOUR HUNDRED NINETY NINE
THOUSAND TWO HUNDRED FIFTY and No/100 ($1,499,250.00) Dollars bearing no
interest (except in the event of maturity or default). The aforesaid principal
sum and interest, if applicable, shall be paid in lawful money of the United
States of America, which shall be legal tender in payment of all debts and dues,
public and private, at the time of payment. Upon the Maturity Date (as
hereinafter defined) such principal shall be due and payable in full.

                  This Note is prepayable in whole or in part at any time
without penalty or premium.

                  For purposes hereof, the "Maturity Date" shall be the date
upon the earlier to occur of either: (i) the closing of the "Resale" of the
Mortgaged Property (as defined below) in accordance with the terms and
definitions contained in that certain Agreement of Purchase and Sale between
HBC, as successor to Heftel, and Payee dated September 7, 1995, as amended (the
"Agreement"), or (ii) the expiration of all rights to effectuate a "Subdivision"
pursuant to Section 18 of the Agreement.

                  It is agreed that if any payment of principal or interest or
any installment thereof, not be made within five (5) days following the date
that same is due as above provided; or if a default occurs under paragraph 12 of
the Mortgage (as hereinafter defined) which default remains uncured for a period
of fifteen (15) days following receipt by Maker of written notice thereof from
Payee; then, in any or all such events, the entire amount of principal of this
Note with all interest then accrued, shall, at the option of Payee and without
further notice (the Maker expressly waives notice of such default), become and
be due and collectible, time being of the essence of this Note. If this Note
shall not be paid at maturity or according to the tenor thereof and strictly as
above provided, it may be placed in the hands of an attorney at law for
collection, and in that event,



                                       1

each party liable for the payment hereof, as Maker, endorser, guarantor, or
otherwise, hereby agrees to pay Payee in addition to the sums above stated, a
reasonable sum as an attorney's fee, which shall include attorney's fees at
trial level and on appeal, together with all reasonable costs incurred in
connection therewith, whether suit be brought or not. After maturity and during
a period of default, this Note shall bear interest at a rate equal to the lesser
of: (i) fifteen (15%) percent per annum, or (ii) the highest rate permitted
under then applicable law.

                  Nothing herein contained, nor in any instrument or transaction
related hereto, shall be construed or so operate as to require the Maker, or any
person liable for the payment of the loan made pursuant to this Note, to pay
interest in an amount or at a rate greater than the highest rate permissible
under applicable law. Should any interest or other charges paid by the Maker, or
any parties liable for the payment of the loan made pursuant to this Note,
result in the computation or earning of interest in excess of the highest rate
permissible under applicable law, then any and all such excess shall be and the
same is hereby waived by Payee, and all such excess shall be automatically
credited against and in reduction of the principal balance, and any portion of
said excess which exceeds the principal balance shall be paid by Payee to the
Maker and any parties liable for the payment of the loan made pursuant to this
Note, it being the intent of the parties hereto that under no circumstances
shall the Maker, or any parties liable for the payment of the loan hereunder, be
required to pay interest in excess of the highest rate permissible under
applicable law.

                  This Note is secured by a Purchase Money Mortgage and Security
Agreement (the "Mortgage") of even date herewith from HBC in favor of Payee
encumbering and conveying real estate and property (the "Mortgaged Property")
therein described and duly recorded among the Public Records of Broward County,
Florida, the terms and provisions of which are incorporated herein by this
reference.

                  As to this Note and the Mortgage and any other instruments
securing the indebtedness evidenced under the Note and/or Mortgage, the Maker,
endorsers and guarantors severally waive all applicable exemption rights,
whether under the State Constitution, Homestead laws or otherwise, and also
severally waive presentment, protest and demand, notice of protest, demand and
any other notice of any kind, dishonor and nonpayment of this Note, and
expressly agree that the Maturity Date of this Note, or any payment hereunder,
may be extended from time to time without in any way affecting the liability of
the Maker, endorsers or guarantors.

guarantor hereof may have against the holder hereof, other than the claims
arising out of the sale of the Mortgaged Property pursuant to the Agreement or
any other claims under or pursuant to the Agreement.
