CLEAR CHANNEL TO  CREATE

LEADING SPANISH RADIO BROADCASTER


San Antonio, Texas, July 9, 1996 - Lowry Mays, President and Chief Executive
Officer of Clear Channel Communications, Inc. (Clear Channel), and McHenry T.
Tichenor, Jr., President and Chief Executive Officer of Tichenor Media System,
Inc.  (TMS), jointly announced today that, subject to Clear Channel completing
its previously announced tender offer to acquire Heftel Broadcasting
Corporation (Heftel), Clear Channel will submit to the Board of Directors of
Heftel an agreement to merge Heftel and TMS  (the Merger).  Under the terms of
the proposed Merger, TMS stockholders will exchange the capital stock of  TMS
for approximately 5.68 million shares of Heftel Class A common stock and
approximately $3.2 million in cash.

In addition to the completion of Clear Channel's tender offer, the Merger is
subject to certain conditions, including approval of the Merger by the Board of
Directors and stockholders of Heftel, approval of the Merger by the
stockholders of TMS, and the approval of the Federal Communications Commission
and the Federal Trade Commission.  There can be no assurance that the
conditions will be satisfied or that the Merger will be consummated.
<PAGE>   2
In order to comply with FCC attribution rules and regulations, as part of the
terms of the proposed Merger, Clear Channel would convert its Class A common
stock in Heftel into newly authorized  non-voting Class B common stock.
Additionally, it is anticipated that Clear Channel's ownership in excess of 30%
of the outstanding shares of common stock of Heftel would be transferred to
Heftel.  Clear Channel would receive an option to reacquire such shares from
Heftel subject to FCC approval.

The combined Heftel/TMS company (New Heftel) would be the only Spanish-language
radio company to own and operate Spanish-language radio stations in each of the
top-ten Hispanic markets in the United States.  New Heftel would own the top
rated Spanish-language radio station in eight of the top ten Hispanic markets
and would own the top rated radio station in any format in four of the top ten
markets (Los Angeles, San Antonio, El Paso, and McAllen/Brownsville/Harlingen)
among Adults 25-54 years old.  McHenry Tichenor, Jr. would become the Chief
Executive Officer of New Heftel which would be headquartered in Dallas, Texas.

Mr. Mays said, "We went forward with the tender offer for Heftel based on a
strong belief in Spanish-language radio and the fact that we were uniquely
positioned to consolidate the business.  We view the merger of Heftel and
Tichenor Media System as the most essential step in the process of
consolidating the Spanish-language radio industry.  We believe that New
Heftel's strategic position and the Tichenor management team will create a
platform to be a leader in Spanish-language radio.  Under Mac Tichenor's
management, Tichenor Media System commands the largest audience and revenue
share of  any Spanish-language radio operator in each of its markets.  TMS
primarily did it the hard way, by acquiring and converting English-formatted
stations to top-rated Spanish-language stations.  In so doing, TMS has provided
its shareholders a superior return, and we are optimistic that our investment
in New Heftel will continue to increase in value under Mac's leadership."

Mr. Tichenor said, "The combination of Heftel and Tichenor Media System will
<PAGE>   3
create the largest Spanish-language radio broadcaster in the United States and
the only one with a presence in each of the top ten Hispanic markets.  We
believe that the combination of these two highly successful, quality-driven
companies will allow us to offer exciting and unprecedented opportunities to
our audiences, advertisers, employees and shareholders."

New Heftel's radio stations will reach approximately 17.3 million Hispanics, or
approximately 63% of the total Hispanic population in the United States.
Hispanic households on average are larger younger and growing faster in number
than Non-Hispanic households.  As a result, Hispanic-related consumer
expenditures are expected to outpace the growth in total consumer expenditures
in the United States, and Hispanic advertising revenues are expected to grow at
a faster rate than radio advertising revenues in the general market.

Subsequent to the Merger, New Heftel will be the leading Spanish-language radio
company in the United States.  The stations of the merged company, including
pending acquisitions, will be as follows:

HEFTEL BROADCASTING CORPORATION
 
     The following information amends and supplements the Offer to Purchase
dated June 7, 1996 (the "Offer to Purchase") of Clear Channel Radio, Inc., a
Nevada corporation (the "Purchaser") and an indirect wholly-owned subsidiary of
Clear Channel Communications, Inc., a Texas corporation ("Parent"), pursuant to
which the Purchaser has offered to purchase all outstanding shares (the
"Shares") of Class A Common Stock, par value $.001 per share (the "Class A
Common Stock"), and Class B Common Stock, par value $.001 per share (the "Class
B Common Stock" and together with the Class A Common Stock, the "Common Stock"),
of Heftel Broadcasting Corporation, a Delaware corporation (the "Company"), at a
purchase price of $23.00 per Share, net to the seller in cash, without interest
(the "Offer Price"), upon the terms and subject to the conditions set forth in
this Supplement, the Offer to Purchase and the related Letter of Transmittal
(which, as amended from time to time, collectively constitute the "Offer").
Terms not defined herein have the meanings set forth in the Offer to Purchase.
 
EXTENSION OF OFFER
 
     The Purchaser has extended the Offer. THE OFFER AND WITHDRAWAL RIGHTS WILL
NOW EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, ON THURSDAY, JULY 25, 1996,
UNLESS THE OFFER IS FURTHER EXTENDED. All references to the Expiration Date in
the Offer to Purchase are amended to mean 12:00 Midnight, New York City time, on
Thursday, July 25, 1996, unless the Purchaser shall have further extended the
period of time for which the Offer is open, in which event the term "Expiration
Date" shall mean the latest time and date at which the Offer, as so extended by
the Purchaser, shall expire. As of the close of business on July 10, 1996,
145,200 Shares had been tendered in the Offer.
 
CHANGE IN CAPITALIZATION
 
     The following information amends and supplements the information set forth
in the Offer to Purchase under the caption "Introduction."
 
     The Company has informed the Purchaser that subsequent to June 7, 1996 (the
date of the Offer to Purchase), all Shares of Class B Common Stock that are not
subject to the Stockholder Purchase Agreement (including Shares of Class B
Common Stock issuable upon exercise of warrants) were sold or transferred by the
holders thereof in transactions that caused such Shares to be converted into
Shares of Class A Common Stock. In addition, the Company has informed the
Purchaser that subsequent to June 7, 1996, options to acquire 43,333 Shares of
Class A Common Stock were exercised. Consequently, as of July 9, 1996, there

outstanding stock options, and (b) 3,356,529 shares of Class B Common Stock

PURCHASER'S RIGHT TO EXTEND OFFER
 
     As discussed more fully below under the caption "Amendments to Tender Offer
Agreement", on July 2, 1996, the Purchaser and the Company amended the Tender
Offer Agreement to provide that the Purchaser may unilaterally extend the
Expiration Date for the Offer until such time as all conditions to the purchase
of the Shares pursuant to the Tender Offer Agreement are met, unless the Tender
Offer Agreement has been terminated in accordance with its terms. Accordingly,
the following two paragraphs amend and restate in their entirety the third and
fifth paragraphs respectively under the caption "1. Terms of the Offer" of the
Offer to Purchase.
 
          Pursuant to the Tender Offer Agreement, if prior to 12:00 Midnight,
     New York City time, on July 16, 1996, the number of Shares tendered in the
     Offer, when combined with the Shares of Class A Common Stock owned by
     affiliates of the Purchaser, total 80% of the outstanding Shares of Common
     Stock, Purchaser shall publish notice of such fact and shall extend the
     Expiration Date by ten days.
<PAGE>   3
 
     Pursuant to the Tender Offer Agreement, without the consent of the Company,
     the Purchaser may not (a) reduce the Offer Price, (b) amend or add to the
     conditions to the obligations of the Purchaser to purchase Shares pursuant
     to the Tender Offer Agreement, (c) change the number of shares of Common
     Stock subject to the Offer, (d) change the form of consideration payable in
     the Offer, or (e) terminate the Offer, except as provided in the Tender

          In addition, if by the Expiration Date any or all conditions of the
     Offer are not satisfied, the Purchaser reserves the right (i) subject to
     complying with any applicable rules and regulations of the Commission,
     including Rule 14e-1(c), to delay acceptance for payment of or payment for
     any Shares until satisfaction or waiver of the conditions to the Offer,
     (ii) to extend the period during which the Offer is to remain open (but not
     beyond 12:00 midnight, New York City time, on October 30, 1996) and,
     subject to the rights of tendering stockholders to withdraw their Shares,
     retain all tendered Shares until the Expiration Date, or (iii) to waive any
     or all conditions of the Offer and, subject to complying with applicable
     rules and regulations of the Commission, accept for payment and purchase
     all validly tendered Shares and not extend the Offer.
 
     The following paragraph amends and restates in its entirety the first
paragraph under the caption "2. Acceptance for Payment and Payment for Shares"
of the Offer to Purchase.
 
          Upon the terms and subject to the conditions of the Offer (including,
     if the Offer is extended or amended, the terms and conditions of any such
     extension or amendment), the Purchaser will accept for payment (and thereby
     purchase) and pay for all Shares validly tendered prior to the Expiration
     Date and not theretofore withdrawn in accordance with Section 4 as promptly
     as practicable after the later of (1) the Expiration Date, (2) the
     satisfaction or waiver of the conditions set forth in Section 14, and (3)
     any date on or prior to October 30, 1996 until which the Purchaser has
     extended the Offer pursuant to the Tender Offer Agreement. For a
     description of the Purchaser's right to terminate the Offer and not accept
     for payment or pay for Shares or to delay acceptance for payment or payment
     for Shares, see Sections 12 and 14.
 
     The following amends and restates in their entirety the first three lines
of the first paragraph under the caption "14. Certain Conditions of the Offer"
of the Offer to Purchase.
 
          Notwithstanding any other provisions of the Offer, and in addition to
     the Purchaser's rights to extend and amend the Offer (subject to the
     provisions of the Tender Offer Agreement), the Purchaser shall not be
     required to accept for payment or, subject to any applicable rules and
     regulations of the Commission, including Rule 14e-1(c) under the Exchange
     Act relating to the obligation of the Purchaser to pay for or return
     tendered Shares promptly after the termination or withdrawal of the Offer,
     pay for, tendered Shares unless and until the following conditions shall
     have been satisfied or waived:
 
     The following amends and restates in its entirety the second paragraph
under the caption "14. Certain Conditions of the Offer" of the Offer to
Purchase.
 
          If any of the foregoing conditions shall not have been satisfied prior
     to acceptance for payment of any tendered Shares, the Purchaser may extend
     the period during which the Offer is to remain open, or subject to the
     terms of the Tender Offer Agreement, terminate or amend the Offer or,
     subject to any applicable rules and regulations of the Commission,
     including Rule 14e-1(c) under the Exchange Act relating to the obligation
     of the Purchaser to pay for or return tendered Shares promptly after the
     termination or withdrawal of the Offer, postpone the acceptance for payment
     of, or payment for, tendered Shares.
 
PROPOSED ACQUISITION OF TICHENOR MEDIA SYSTEM, INC.
 
     The following information amends and supplements the information set forth
in the Offer to Purchase under the captions "7. Effect of the Offer on the
Market for the Class A Common Stock, Stock Quotation and Exchange Act
Registration", "8. Certain Information Concerning the Company", "9. Certain
Information Concerning the Purchaser and Parent", and "12. Purpose of the Offer;
The Tender Offer Agreement, Stockholder Purchase Agreement, Settlement
Agreements and Agreements Not to Compete".
 
                                        2
<PAGE>   4
 
     On July 9, 1996, Parent and Tichenor Media System, Inc., a Texas
corporation ("Tichenor"), entered into an Agreement and Plan of Merger (the
"Tichenor Merger Agreement") which, subject to the terms and conditions thereof,
provides for the acquisition of Tichenor by the Company following the Closing of
the Offer and the closing of the Stockholder Purchase Agreement. The existing
management and Board of Directors of the Company were not involved in the
negotiations concerning the acquisition of Tichenor. Tichenor is a national
radio broadcasting company engaged in the business of acquiring, developing and
operating Spanish language radio stations in the major Hispanic markets in the
United States. Tichenor owns or operates 17 Spanish language AM and FM stations
in six markets, including five of the top Hispanic markets in the United States.
If the Tichenor Merger is consummated, the Company will be the only Spanish
language radio company to own and operate Spanish language radio stations in
each of the top ten Hispanic markets in the United States.
 
     Pursuant to the Tichenor Merger Agreement, a to-be-formed wholly-owned
subsidiary of the Company will be merged (the "Tichenor Merger") with and into
Tichenor and the shares of Tichenor capital stock not owned by Parent or its
affiliates outstanding immediately prior to the Tichenor Merger (other than
certain preferred stock) will be converted into shares of the Company's Class A
Common Stock. Pursuant to the Tichenor Merger Agreement, (i) the 667,504.93
shares of outstanding Tichenor common stock not owned by Parent or its
affiliates will be converted into an aggregate of approximately 5,223,960 shares
of the Company's Class A Common Stock, (ii) the 35,772.48 shares of Tichenor's
outstanding Junior Preferred Stock will be converted into on aggregate of
approximately 155,531 shares of the Company's Class A Common Stock, (iii) the
3,000 shares of Tichenor's outstanding 14% Senior Redeemable Cumulative
Preferred Stock will be converted into the right to receive an aggregate of
$3,000,000, plus all accrued and unpaid dividends through December 31, 1995, and
(iv) an existing warrant of Tichenor, or the shares received upon exercise
thereof if the warrant is exercised prior to the effective time of the Tichenor
Merger, shall be converted into 180,000 shares of the Company's Class A Common
Stock. As a result of the Tichenor Merger, Tichenor will become a wholly-owned
subsidiary of the Company.
 
     Prior to consummation of the Tichenor Merger, Parent will purchase 16,664
shares of Tichenor common stock from certain shareholders of Tichenor for
approximately $3,000,000. At the effective time of the Tichenor Merger, each
share of Tichenor common stock owned by Parent or any affiliate of Parent will
be converted into 7.8261 shares of a new class of common stock of the Company
that will not have any voting rights except in certain specified circumstances
described below and as required by law ("Nonvoting Common Stock") and each share
of the Company's Class A Common Stock owned by Parent or any affiliate of Parent
(including the Purchaser) will be converted into one share of Nonvoting Common
Stock. On the closing date of the Tichenor Merger, Parent will transfer a
sufficient number of shares of Nonvoting Common Stock to the Company for $.01
per share so that Parent and its affiliates own 30% of the total number of
shares of Class A Common Stock and Nonvoting Common Stock outstanding
immediately following such transfer, and concurrently therewith, the Company
will grant Parent an immediately exercisable option (the "Option") to acquire a
number of shares of Nonvoting Common Stock equal to the amount so transferred to
the Company for $.01 per share. Exercise of the Option may in certain
circumstances require prior FCC consent.
 
     If the Tichenor Merger is consummated, immediately thereafter the former
shareholders and warrant holders of Tichenor will own approximately 5,559,491
shares of the Class A Common Stock of the Company, representing approximately
55.2% of the total outstanding Class A Common Stock and approximately 32.3% of
the total outstanding common stock of the Company on a fully diluted basis at
such time. In addition, if all of the Shares subject to the Stockholder Purchase
Agreement are acquired by the Purchaser and the only Shares tendered and
acquired by the Purchaser in the Offer are those issuable upon exercise of
warrants and options, then immediately following the Tichenor Merger (a) Parent,
the Purchaser and their affiliates will own approximately 4,319,447 outstanding
shares of the Company's Nonvoting Common Stock, representing approximately 30%
of the total outstanding common stock of the Company at such time, and will own
the Option to acquire approximately 2,839,479 shares of Nonvoting Common Stock
(which when combined with the outstanding Nonvoting Common Stock then owned by
Parent, the Purchaser and their affiliates, will constitute approximately 41.5%
of the total outstanding common stock of the Company on a fully diluted basis),
and (b) the other stockholders of the Company would own the remaining 4,519,219
outstanding shares
 
                                        3
<PAGE>   5
 
of Class A Common Stock, representing approximately 44.8% of the total
outstanding Class A Common Stock and approximately 26.2% of the total
outstanding common stock of the Company on a fully diluted basis at such time.
Upon Closing of the Offer and closing of the Stockholder Purchase Agreement,
there will be no outstanding shares of the Company's existing Class B Common
Stock.
 
     The Tichenor Merger Agreement provides that the Company will take such
actions necessary such that immediately after the effective time of the Tichenor
Merger, five designees of Tichenor shall constitute the entire Board of
Directors of the Company. The Tichenor Merger Agreement also provides that at or
prior to the effective time of the Tichenor Merger, the Company will enter into
an Employment Agreement with McHenry T. Tichenor, Jr. pursuant to which Mr.
Tichenor will serve as Chairman, President and Chief Executive Officer of the
Company for a five year term. The Tichenor Merger Agreement also provides that
the Company will grant certain demand and "piggyback" registration rights to
certain former Tichenor shareholders (including Mr. Tichenor) who will own an
aggregate of 5,407,994 shares of Class A Common Stock following the Tichenor
Merger (collectively, the "Major Tichenor Shareholders"), and will grant certain
demand and piggyback registration rights to Parent with respect to any shares of
Class A Common Stock that may be held from time to time by Parent and/or its
affiliates following the Tichenor Merger. It is also contemplated that Parent,
the Purchaser and the Major Tichenor Shareholders will enter into a Stockholders
Agreement with the Company whereby such stockholders will agree to certain
restrictions on the transfer of their shares of common stock of the Company and
will grant certain rights of first refusal and "tag-along" rights with respect
to certain sales of such shares.
 
     Consummation of the Tichenor Merger is subject to a number of conditions,
including the Closing of the Offer and the closing of the Stockholder Purchase
Agreement, approval of the Tichenor Merger Agreement by the Board of Directors
(the "Board") and the stockholders of the Company following the Closing of the
Offer and the closing of the Stockholder Purchase Agreement; the receipt by the
Company of an opinion from a nationally recognized investment banking firm or
financial advisor that the consideration to be paid by the Company in the
Tichenor Merger is fair to the stockholders of the Company from a financial
point of view; expiration or termination of the applicable waiting period under
the HSR Act; effectiveness under the Securities Act of 1933, as amended, of a
registration statement relating to the securities of the Company to be issued in
the Tichenor Merger; approval of the Tichenor Merger Agreement by the
shareholders of Tichenor; no material adverse effect occurring with respect to
Tichenor or the Company; the receipt and finalization of all required FCC
approvals, licenses and authorizations; and the expiration of a period of at
least six months and one day following the Closing of the Offer and the closing
of the Stockholder Purchase Agreement. There can be no assurance that all of
these conditions will be satisfied or waived or that the Tichenor Merger will be
consummated. As stated above, if the Board of Directors of the Company approves
the Tichenor Merger Agreement following the Closing of the Offer and the closing
of the Stockholder Purchase Agreement, the Tichenor Merger Agreement will be
submitted to the stockholders of the Company for their approval. Parent and the
Purchaser, who will own a majority of the outstanding shares of the Company's
Common Stock at such time, intend to vote all such shares in favor of the
Tichenor Merger Agreement.
 
     The Tichenor Merger Agreement is subject to termination upon the occurrence
of certain events, including by Tichenor if, subsequent to the Closing of the
Offer and the closing of the Stockholder Purchase Agreement, Parent and its
affiliates own or have a contractual right to purchase more than 90% of the
Company's Common Stock then outstanding.
 
     If the Tichenor Merger is consummated, Mr. Tichenor and certain members of
his family (collectively, the "Tichenor Family" ) will own an aggregate of
approximately 4,569,404 shares of Class A Common Stock (representing
approximately 45.3% of the then outstanding Class A Common Stock) and may have
the ability, if they act together as a group, to control the Company. The
members of the Tichenor Family have entered into a Voting Agreement pursuant to
which the majority of the shares of Tichenor common stock and Junior Preferred
Stock currently held by them, as well as the approximately 4,434,303 shares of
the Company's Class A Common Stock to be received in exchange therefor in the
Tichenor Merger, shall be voted in accordance with the instructions of McHenry
T. Tichenor, Jr. or McHenry T. Tichenor, Sr. until such time as the FCC shall
have approved an amendment to such agreement, whereupon the shares subject to
the voting agreement shall be voted in accordance with the instructions of the
holders of a majority of such shares.
 
                                        4
<PAGE>   6
 
Parent and its affiliates (including the Purchaser) will own only Nonvoting
Common Stock as a result of the Tichenor Merger and thus will not have the right
to vote for the election of directors of the Company, although Parent and its
affiliates will have certain class voting rights discussed in more detail below.
 
     The Nonvoting Common Stock that Parent and its affiliates will receive in
the Tichenor Merger will convert into Class A Common Stock automatically upon
sale or transfer to a person or entity other than Parent or an affiliate of
Parent. Each share of the Nonvoting Common Stock will also be convertible into
Class A Common Stock at the option of its holder. In addition, Parent and its
affiliates may convert shares of Class A Common Stock held by them into shares
of Nonvoting Common Stock at their option.
 
     Holders of the Nonvoting Common Stock will in certain circumstances have
certain voting rights. Specifically, so long as Parent and its affiliates own at
least 20% of the Company's common stock then outstanding (calculated as if
Parent owns all shares of Nonvoting Common Stock subject to the Option), the
Company shall not, and shall not permit any subsidiary to, without the vote or
consent by the holders of a majority of the Nonvoting Common Stock voting as a
single class, take any of the following actions: (i) effect the sale, lease or
other transfer of all or substantially all of the assets of the Company, or any
merger or consolidation involving the Company where the stockholders of the
Company immediately prior to such transaction would not own at least 50% of the
capital stock of the surviving entity, or any reclassification,
recapitalization, dissolution, liquidation or winding up of the Company; (ii)
authorize, issue or obligate itself to issue any shares of Preferred Stock;
(iii) make or permit any amendment to the Company's certificate of incorporation
that adversely affects the rights of the holders of Nonvoting Stock; (iv)
declare or pay any non-cash dividends on or make any other non-cash distribution
on its common stock; or (v) make or permit any amendment or modification to the
Company's certificate of incorporation concerning the Company's common stock.
 
     Concurrently with the execution of the Tichenor Merger Agreement, Parent
and a subsidiary of Tichenor entered into a Loan Agreement (the "Tichenor Loan
Agreement"), pursuant to which, and subject to the terms and conditions thereof,
Parent has agreed to loan up to $40,000,000 to the Tichenor subsidiary to
finance the subsidiary's acquisition of two FM radio stations and related assets
serving the San Francisco, San Jose and Oakland markets. Parent's obligation to
provide funds under the Tichenor Loan Agreement is subject to certain
conditions, including approval of the Tichenor Merger Agreement by the
shareholders of Tichenor.
 
     The foregoing summary of the Tichenor Merger Agreement and related
agreements does not purport to be complete and is qualified in its entirety by
reference to the text of such documents, which is herein incorporated by
reference, copies of which have been filed as exhibits to the Schedule 14D-1.
 
     Set forth below is certain selected consolidated financial information
provided by Tichenor to Parent with respect to Tichenor and its subsidiaries for
the years ended December 31, 1994 and 1995 and for the five months ended May 31,
1996. The selected data for the years ended December 31, 1994 and 1995 are
derived from the audited financial statements of Tichenor for such years.

AMENDMENTS TO TENDER OFFER AGREEMENT
 
     The following information amends and supplements the information set forth
in the Offer to Purchase under the caption "11. Contacts with the Company;
Background of the Offer", and the description of the Tender Offer Agreement set
forth in the Offer to Purchase under the caption "12. Purpose of the Offer; The
Tender Offer Agreement, Stockholder Purchase Agreement, Settlement Agreements
and Agreements Not to Compete."
 
     On June 20, 1996, the parties to the Tender Offer Agreement entered into an
amendment ("Amendment No. 2") to the Tender Offer Agreement which amends certain
provisions therein as follows:
 
          (i) Amendment No. 2 amends the provision relating to the Company's
     filing with the Commission of a Solicitation/Recommendation Statement on
     Schedule 14D-9 (as may be amended from time to time, the "Schedule 14D-9")
     to require the Company to file on or before June 21, 1996 such Schedule
     14-9 which shall reflect either the recommendation of the Company's Board
     to accept the Offer or a statement by the Board that it is not expressing
     an opinion, and is remaining neutral, with respect to the Offer. The
     Company is required to mail copies of such Schedule 14D-9, excluding
     exhibits, to its stockholders on or before June 21, 1996. The Purchaser has
     been informed by the Company that such copies were mailed on June 21, 1996,
     and that the Board has determined not to express an opinion, and to remain
     neutral, with respect to whether stockholders should accept the Offer and
     tender their Shares.
 
          (ii) Amendment No. 2 adds a provision to the Tender Offer Agreement
     which states that the Company will, concurrently with the Closing of the
     Offer, take all actions necessary to cause persons designated by the
     Purchaser to become directors of the Company so that such persons shall
     constitute at least a majority of the Board or if the Purchaser so
     requests, all of the directors of the Company. In furtherance thereof, the
     Company will increase the size of the Board, or use reasonable efforts to
     secure the resignation of directors, or both, as is necessary to permit the
     Purchaser's designees to be elected to the Board. At such time, the Company
     also will cause persons designated by the Purchaser to constitute at least
     a majority of each committee of the Board or if the Purchaser so requests,
     all of the directors on each committee of the Company's Board. The
     Company's obligations to appoint designees to the Board shall be subject to
     Section 14(f) of the Exchange Act, and Rule 14f-1 promulgated thereunder.
     The Purchaser is required to supply the Company will all information which
     the Company shall reasonably request with respect to nominees in connection
     with the filing required by Section 14(f) of the Exchange Act. As of the
     date of this Supplement, the Purchaser had not determined the persons who
     shall be designees to the Board.
 
          (iii) Amendment No. 2 amends the condition in the Tender Offer
     Agreement that the Company's representations and warranties therein remain
     true and correct in all material respects to provide that the
 
                                        6
<PAGE>   8
 
     representation and warranty that the Board has resolved to recommend
     acceptance of the Offer need only be true as of June 1, 1996.
 
          (iv) Amendment No. 2 amends the termination provision of the Tender
     Offer Agreement described in clause (iv) under "12. Purpose of the Offer;
     The Tender Offer Agreement, Stockholder Purchase Agreement, Settlement
     Agreements and Agreements Not to Compete -- Tender Offer Agreement --
     Termination" to provide that the Tender Offer Agreement and the Offer may
     be terminated by either the Company or the Purchaser at any time prior to
     the Closing of the Offer, if (a) the Company shall have determined pursuant
     to duly adopted resolutions of the Board, to recommend against acceptance
     of the Offer by reason of receipt of a Takeover Proposal (as such term is
     defined in the Tender Offer Agreement); (b) the Company after receipt of a
     Takeover Proposal shall not have, within five days after being so requested
     by the Purchaser, determined pursuant to duly adopted resolutions to
     recommend acceptance of the Offer, or after so recommending acceptance of
     the Offer shall have withdrawn or modified or resolved to modify or
     withdraw such recommendation; or (c) the Company recommends, pursuant to
     duly adopted resolutions, any Takeover Proposal from a person or entity
     other than the Purchaser or its affiliates; provided, however, that the
     Purchaser shall not terminate the Tender Offer Agreement pursuant to
     subsection (a) hereof if as a result of the Company's receipt of a Takeover
     Proposal from a third-party the Company, as required by applicable law as
     advised by outside counsel, recommends against acceptance of the Offer, but
     within five business days thereafter the Company publicly withdraws its
     recommendation against acceptance of the Offer.
 
     On July 2, 1996, the parties to the Tender Offer Agreement entered into a
third amendment ("Amendment No. 3") to the Tender Offer Agreement which amends
the Tender Offer Agreement to allow the Purchaser to extend the Expiration Date
for the Offer until such time as all conditions to the consummation of the
transaction contemplated thereby are met, unless the Tender Offer Agreement has
been terminated in accordance with the provisions thereof.
 
     The foregoing summary of the Tender Offer Agreement, as amended, does not
purport to be complete and is qualified in its entirety by reference to the text
of Amendment No. 2 and the text of Amendment No. 3, both of which are herein
incorporated by reference, and a copy of each of which has been filed as an
exhibit to the Schedule 14D-1.
 
     On June 20, 1996, the Selling Stockholders executed a consent whereby each
Selling Stockholder consented to Amendment No. 2 to the Tender Offer Agreement
and acknowledged and agreed that any references to the Tender Offer Agreement in
the Stockholder Purchase Agreement shall mean the Tender Offer Agreement, as
amended by Amendments No. 1 and 2 thereto and any subsequent amendments.
 
EXPIRATION OF HSR WAITING PERIOD
 
     The following information amends and supplements the information set forth
in the Offer to Purchase under the captions "Introduction", "14. Certain
Conditions of the Offer" and "15. Certain Regulatory and Legal Matters."
 
     The waiting period under the HSR Act has expired. Accordingly, the
condition to the Offer requiring the expiration or termination of such waiting
period has been satisfied.
 
CERTAIN LITIGATION
 
     On June 14, 1996, a purported stockholder class action suit was filed in
the Court of Chancery in the State of Delaware (Levine v. Heftel, et al., C.A.
No. 15066). The Levine action names as defendants the Company, Parent and
certain individual directors and senior executive officers of the Company
(collectively, the "Individual Defendants"). In general, the Levine action
alleges that, among other things, the defendants breached their fiduciary
duties, because the Offer is "grossly unfair" to the stockholders and is
"substantially below true value and is a product of defendants' conflict of
interest." The action also alleges that the Company and Parent failed to
adequately reveal the consideration involved in the Settlement Agreements and
Agreements Not to Compete entered into with Cecil Heftel and Carl Parmer,
despite the fact that such information was disclosed in the Schedule 14D-1 and
Offer to Purchase. Additionally, the action alleges that given the Individual
Defendants' "domination and control" of the Board, they cannot be expected to
act
 
                                        7
<PAGE>   9
 
independently, and consequently, in order for such individuals not to breach
their fiduciary duties, a recommendation of the transaction from "a truly
independent representative of the public stockholders" or obtaining the majority
approval of the public unaffiliated stockholders of the Company is required. The
plaintiff is seeking, among other things, certification as a class action,
preliminary and permanent injunctive relief, rescissory damages in the event the
Offer is consummated, compensatory damages, and costs, disbursements and legal
fees relating to the action. Parent believes that the Levine action is meritless
and intends to oppose it vigorously.
 
     The foregoing summary of the Levine action does not purport to be complete
and is qualified in its entirety by reference to the text of such action, a copy
of which has been filed as an exhibit to the Schedule 14D-1.

                   AMENDMENT NO. 3 TO TENDER OFFER AGREEMENT

         The Tender Offer Agreement dated June 1, 1996, as amended,  between
Clear Channel Radio, Inc., a Nevada corporation, and Heftel Broadcasting
Corporation, a Delaware corporation, is hereby amended as follows:

         1.      Section 1.1 is deleted in its entirety and replaced by the
                 following new Section 1.1:

                 "1.1     The Offer.  Subject to the provisions of this
                          Agreement, as promptly as practicable, but in no
                          event later than five business days after the
                          announcement of the Offer by Parent, Parent shall
                          commence the Offer.  Subject to Article 8, the Offer
                          shall remain open for 40 days; provided, however, if
                          at any time prior to the end of such 40 day period,
                          shares of Company Common are tendered to Parent which
                          when combined with the shares of Class A Common stock
                          owned by affiliates of Parent total 80% of the
                          outstanding shares of Company Common, Parent shall
                          publish notice of such fact and shall extend the
                          termination date for the Offer by 10 days.  Parent
                          expressly reserves the right to modify the terms of
                          the Offer, except that, without the consent of the
                          Company, Parent shall not (a) reduce the Offer Price,
                          (b) amend or add to the conditions to the obligations
                          of Parent to complete the transactions contemplated
                          hereby set forth in Article 7 (the "Closing
                          Conditions"), (c) change the number of shares of
                          Company Common subject to the Offer, (d) change the
                          form of consideration payable in the Offer, or (e)
                          terminate the Offer except in accordance with Section
                          8.1.  Notwithstanding any other provision in this
                          Agreement to the contrary, Parent shall have the
                          right to extend the termination date for the Offer
                          until such time as all conditions to the consummation
                          of the transactions contemplated hereby are met,
                          unless this Agreement has been terminated in
                          accordance with the provisions hereof.  Subject to
                          the terms and conditions of this Agreement, on the
                          Closing Date, Parent shall pay for all shares of
                          Company Common validly tendered and not withdrawn
                          prior to the termination of the Offer."

         Shareholder pursuant to the TBCA; provided, however, shares of
         Tichenor Common Stock, Tichenor Senior Preferred or Tichenor Junior
         Preferred outstanding at the Effective Time and held by a Dissenting
         Shareholder who shall, after the Effective Time, withdraw his demand
         for payment or lose his dissenters' right as provided in the TBCA,
         shall be deemed to be converted, as of the Effective Time, into the
         right to receive the shares of Heftel Common Stock or cash specified
         in Section 2.4(b)(i), (ii) and (iii), respectively, in accordance with
         the procedures specified in Section 2.5(b).  Tichenor shall give
         Parent (or, if after consummation of the Assignment Agreement, Heftel)
         (A) prompt notice of any written demands for such payment, withdrawals
         of demands for such payment and any other instruments served pursuant
         to the TBCA received by Tichenor, and (B) the opportunity to direct
         all negotiations and proceedings with respect to demands for such
         payment under the TBCA.  Tichenor will not voluntarily make any
         payment with respect to any demands for dissenters' rights and will
         not, except with the prior written consent of Parent (or, if after
         consummation of the Assignment Agreement, Heftel), settle or offer to
         settle any such demands.

                          (ix)    HEFTEL COMMON STOCK HELD BY PARENT.  At the
         Effective Time, by virtue of the Merger and without any action on the
         part of Parent or any Affiliate of Parent (but subject to the
         provisions of Section 2.5(e)), each share of Heftel Common Stock that
         is issued and outstanding immediately prior to the Effective Time and
         held by Parent or any Affiliate of Parent shall be converted into the
         right to receive one (1) share of validly issued, fully paid and
         nonassessable New Heftel Class B Common Stock.  Each





                                       14
<PAGE>   18
         share of Heftel Common Stock, when so converted, shall automatically
         be cancelled and retired, shall cease to exist and shall no longer be
         outstanding; and the holder of any certificate representing any such
         shares shall cease to have any rights with respect thereto, except the
         right to receive the shares of New Heftel Class B Common Stock to be
         issued in exchange therefor (along with any unpaid dividends and
         distributions with respect to such shares of New Heftel Class B Common
         Stock as provided in Section 2.5(c)), without interest, upon the
         surrender of such certificate in accordance with Section 2.5.

         2.5     EXCHANGE OF CERTIFICATES.

                 (a)      EXCHANGE FUND.  At or prior to the Effective Time,
Heftel shall deposit with the Exchange Agent: (i) for the benefit of the
holders of (A) shares of Tichenor Common Stock (other than Parent and
Affiliates of Parent), (B) shares of Tichenor Junior Preferred and (C) the
Tichenor Warrant, if outstanding as of the Effective Time, and for exchange in
accordance with this Agreement, certificates representing the shares of Heftel
Common Stock to be issued in exchange for such Tichenor securities pursuant to
Section 2.4(b)(i), (iii) and (vi), respectively; (ii) for the benefit of the
holders of Tichenor Senior Preferred, cash in the amount of $3,000,000; (iii)
for the benefit of Parent and Affiliates of Parent, certificates representing

2.4(b)(v) and (ix); and (iv) cash in an amount sufficient to provide for the
payments to be made in lieu of issuing any fractional shares of Heftel Common
Stock or New Heftel Class B Common Stock as provided in Section 2.5(e).
Additionally, subject to the provisions of Section 2.5(f), Heftel shall, if and
when a payment date has occurred with respect to a dividend or distribution
that has been declared subsequent to the Effective Time, deposit with the
Exchange Agent an amount in cash (or property of like kind to that which is the
subject of such dividend or distribution) equal to the dividend or distribution
per share of Heftel Common Stock times the number of shares of Heftel Common
Stock evidenced by Tichenor Certificates theretofore representing Tichenor
Common Stock, Tichenor Junior Preferred and the Tichenor Warrant that have not
theretofore been surrendered for exchange in accordance with this Section 2.5.
The cash to be paid in conversion of the Tichenor Senior Preferred, such shares
of Heftel Common Stock and New Heftel Class B Common Stock, together with any
dividends or distributions with respect thereto (as provided in Section
2.5(c)), are referred to herein as the "EXCHANGE FUND."  The Exchange Agent,
pursuant to irrevocable instructions consistent with the terms of this
Agreement, shall deliver the Heftel Common Stock to be issued pursuant to
Section 2.4(b)(i), (iii) and (vi), respectively, the New Heftel Class B Common
Stock to be issued pursuant to Section 2.4(b)(v) and (ix), the cash to be paid
pursuant to Section 2.4(b)(ii), and cash in an amount sufficient to provide for
the payments to be made in lieu of issuing any fractional shares of Heftel
Common Stock or New Heftel Class B Common Stock as provided in Section 2.5(e)
out of the Exchange Fund, and the Exchange Fund shall not be used for any other
purpose whatsoever.  The Exchange Agent shall not be entitled to vote or
exercise any rights of ownership with respect to the Heftel Common Stock or the
New Heftel Class B Common Stock held by it from time to time hereunder, except
that it shall receive and hold all dividends or other distributions paid or
distributed with respect thereto for the account of Persons entitled thereto.

                 (b)      EXCHANGE PROCEDURES.

                          (i)     As soon as reasonably practicable after the
         Effective Time, Heftel shall cause the Exchange Agent to mail to each
         holder of record of a Tichenor Certificate that, immediately prior to
         the Effective Time, represented (A) shares of Tichenor Common Stock,
         (B) shares of Tichenor Junior Preferred, (C) the Tichenor Warrant, if

         Certificate, along with instructions for using such letter of
         transmittal to effect such exchange.  As soon as reasonably
         practicable after the Effective Time, Heftel shall cause the Exchange
         Agent to mail to Parent and each Affiliate of Parent that holds Heftel
         Common Stock that immediately prior to the Effective Time was
         converted into the right to receive New Heftel Class B Common Stock
         pursuant to Section 2.4(b)(ix), a letter of transmittal to be used to
         effect the exchange of such Heftel Common Stock, along with
         instructions for using such letter of transmittal to effect such
         exchange.  The letter of transmittal (or the instructions thereto)
         shall specify that delivery of any Tichenor Certificate or Heftel
         Common Stock, as applicable, shall be effected, and risk of loss and
         title thereto shall pass, only upon delivery of thereof to the
         Exchange Agent and shall be in such form and have such other
         provisions as Heftel may reasonably specify.

                          (ii)    Upon surrender to the Exchange Agent of a
         Tichenor Certificate for cancellation, together with a duly completed
         and executed letter of transmittal and any other required documents
         (including, in the case of any Person constituting an "affiliate" of
         Tichenor for purposes of Rule 145(c) and (d) under the Securities Act,
         a written agreement from such Person as described in Section 5.11, if
         not theretofore delivered to Heftel), (A) (x) the holder (other than
         Parent and Affiliates of Parent) of such Tichenor Certificate (other
         than Tichenor Certificates representing Tichenor Senior Preferred)
         shall be entitled to receive in exchange therefor a Heftel Certificate
         representing the number of whole shares of Heftel Common Stock that
         such holder has the right to receive pursuant to Section 2.4(b)(i),
         (iii), or (vi), as the case may be, any cash in lieu of fractional
         shares of Heftel Common Stock as provided in Section 2.5(e), and any
         unpaid dividends and distributions that such holder has the right to
         receive pursuant to Section 2.5(c) (after giving effect to any
         required withholding of taxes), (y) Parent and Affiliates of Parent
         holding a Tichenor Certificate shall be entitled to receive in
         exchange therefor a certificate representing the number of whole
         shares of New Heftel Class B Common Stock that such holder has the
         right to receive pursuant to Section 2.4(b)(i)(v), any cash in lieu of
         fractional shares of New Heftel Class B Common Stock as provided in
         Section 2.5(e), and any unpaid dividends and distributions that such
         holder has the right to receive pursuant to Section 2.5(c) (after
         giving effect to any required withholding of taxes), and (z) the
         holder of such Tichenor Certificate representing Tichenor Senior
         Preferred shall be entitled to receive in exchange therefor cash
         pursuant to Section 2.4(b)(ii); and (B) the Tichenor Certificate so
         surrendered shall forthwith be cancelled.  No interest shall be paid
         or accrued on the cash in lieu of fractional shares and unpaid
         dividends and distributions, if any, payable to holders of Tichenor
         Certificates.  Upon surrender to the Exchange Agent by Parent or an
         Affiliate of Parent of a certificate representing Heftel Common Stock
         for cancellation, together with a duly completed and





                                       16
<PAGE>   20
         executed letter of transmittal and any other required documents, the
         holder of such certificate shall be entitled to receive in exchange
         therefor a certificate representing the number of whole shares of New
         Heftel Class B Common Stock that such holder has the right to receive
         pursuant to Section 2.4(b)(ix), and any unpaid dividends and
         distributions that such holder has the right to receive pursuant to
         Section 2.5(c) (after giving effect to any required withholding of
         taxes) and the certificate so surrendered shall forthwith be
         cancelled.  No interest shall be paid or accrued on the unpaid
         dividends and distributions, if any, payable to holders of the
         certificates representing Heftel Common Stock surrendered for
         cancellation.

                          (iii)   In the event of a transfer of ownership of
         Tichenor Common Stock, Tichenor Junior Preferred or the Tichenor
         Warrant, if outstanding as of the Effective Time, that is not
         registered in the transfer records of Tichenor, a Heftel Certificate
         representing the appropriate number of shares of Heftel Common Stock
         (along with any cash in lieu of fractional shares and any unpaid
         dividends and distributions that such holder has the right to receive)
         may be issued or paid to a transferee if the Tichenor Certificate
         representing such Tichenor securities is presented to the Exchange
         Agent accompanied by all documents required to evidence and effect
         such transfer and to evidence that any applicable stock transfer or
         similar taxes have been paid.

                          (iv)    Until surrendered as contemplated by this
         Section 2.5(b), (A) each Tichenor Certificate (other than Tichenor
         Certificates representing Tichenor Senior Preferred and Tichenor
         Certificates representing Heftel Common Stock owned by Parent and
         Affiliates of Parent) shall be deemed at any time after the Effective
         Time to represent only the right to receive upon such surrender a
         Heftel Certificate representing shares of Heftel Common Stock as
         provided in Section 2.4(b)(i), (iii) or (vi), as the case may be
         (along with any cash in lieu of fractional shares and any unpaid
         dividends and distributions), (B) each Tichenor Certificate
         representing Tichenor Senior Preferred shall be deemed at any time
         after the Effective Time to represent only the right to receive upon
         such surrender cash as provided in Section 2.4(b)(ii), (C) each
         certificate representing Heftel Common Stock held by Parent and any
         Affiliate of Parent shall be deemed at any time after the Effective
         Time to represent only the right to receive upon such surrender a
         certificate representing shares of New Heftel Class B Common Stock as
         provided in Section 2.4(b)(ix) (along with any unpaid dividends and
         distributions), and (D) each Tichenor Certificate held by Parent and
         Affiliates of Parent shall be deemed at any time after the Effective
         Time to represent only the right to receive upon such surrender a
         certificate representing New Heftel Class B Common Stock as provided
         in Section 2.4(b)(v) (along with any cash in lieu of fractional shares
         and any unpaid dividends and distributions).

                 (c)      DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No
dividends or other distributions with respect to Heftel Common Stock declared
or made after the Effective Time with a record date after the Effective Time
shall be paid to the holder of any unsurrendered Tichenor Certificate.  Subject
to the effect of applicable laws, (i) at the time of the surrender of a
Tichenor Certificate for exchange in accordance with the provisions of this
Section 2.5, there shall be paid to the surrendering holder, without interest,
the amount of dividends or other distributions (having a record date after the
Effective Time but on or prior to surrender and a





                                       17

payment date on or prior to surrender) theretofore paid with respect to the
number of whole shares of Heftel Common Stock or New Heftel Class B Common
Stock, as applicable, that such holder is entitled to receive (less the amount
of any withholding taxes that may be required with respect thereto); and (ii)
at the appropriate payment date, there shall be paid to the surrendering
holder, without interest, the amount of dividends or other distributions
(having a record date after the Effective Time but on or prior to surrender and
a payment date subsequent to surrender) payable with respect to the number of
whole shares of Heftel Common Stock or New Heftel Class B Common Stock, as

that may be required with respect thereto).  Subject to the effect of
applicable laws, (i) at the time Parent or an Affiliate of Parent surrenders
Heftel Common Stock for exchange in accordance with the provisions of Section
2.4(b)(ix) and this Section 2.5, there shall be paid to the surrendering
holder, without interest, the amount of dividends or other distributions
(having a record date after the Effective Time but on or prior to surrender and

number of whole shares of New Heftel Class B Common Stock that such holder is
entitled to receive (less the amount of any withholding taxes that may be

shall be paid to the surrendering holder, without interest, the amount of
dividends or other distributions (having a record date after the Effective Time

                 (d)      NO FURTHER OWNERSHIP RIGHTS IN TICHENOR SECURITIES.
All shares of Heftel Common Stock and New Heftel Class B Common Stock, as
applicable, issued upon the surrender for exchange of (i) shares of Tichenor
Common Stock, (ii) shares of Tichenor Junior Preferred and (iii) the Tichenor
Warrant, if outstanding as of the Effective Time, in accordance with the terms
hereof (including any cash paid pursuant to Section 2.5(c) or (e)) and the cash
paid upon the surrender for exchange of Tichenor Senior Preferred shall be
deemed to have been issued in full satisfaction of all rights pertaining to
such Tichenor securities.  After the Effective Time, there shall be no further
registration of transfers on the Surviving Corporation's stock transfer books
or other records of the shares of Tichenor Common Stock, Tichenor Senior
Preferred, Tichenor Junior Preferred or the Tichenor Warrant, in each case that
were outstanding immediately prior to the Effective Time.  If, after the
Effective Time, a Tichenor Certificate is presented to the Surviving
Corporation for any reason, it shall be cancelled and exchanged as provided in
this Section 2.5.

                 (e)      TREATMENT OF FRACTIONAL SHARES.  No Heftel
Certificates or scrip representing fractional shares of Heftel Common Stock or
New Heftel Class B Common Stock, as applicable, shall be issued in the Merger
and, except as provided in this Section 2.5(e), no dividend or other
distribution, stock split or interest shall relate to any such fractional
share, and such fractional share shall not entitle the owner thereof to vote or
to any other rights of a stockholder of Heftel.  In lieu of any fractional
share of Heftel Common Stock or New Heftel Class B Common Stock, as applicable,
to which a holder of Tichenor Common Stock, Tichenor Junior Preferred or the
Tichenor Warrant, if outstanding as of the Effective Time, would otherwise be
entitled, such holder, upon surrender of a Tichenor Certificate as described in
this Section, shall be paid an amount in cash (without interest) determined by
multiplying (i) the Share Price by (ii) the fraction of a share of Heftel
Common Stock or New Heftel Class B





                                       18
<PAGE>   22
Common Stock to which such holder would otherwise be entitled, in which case
Heftel shall make available to the Exchange Agent, without regard to any other
cash being provided to the Exchange Agent, the amount of cash necessary to make
such payments.

                 (f)      TERMINATION OF EXCHANGE FUND.  Any portion of the
Exchange Fund and cash held by the Exchange Agent in accordance with the terms
of this Section 2.5 that remains unclaimed by the former shareholders of
Tichenor for a period of one year following the Effective Time shall be
delivered to Heftel, upon demand.  Thereafter, any former securityholders of
Tichenor who have not theretofore complied with the provisions of this Section
2.5 shall look only to Heftel for payment of their claim for Heftel Common
Stock or New Heftel Class B Common Stock, any cash in lieu of fractional shares
of Heftel Common Stock or New Heftel Class B Common Stock and any dividends or
distributions with respect to Heftel Common Stock or New Heftel Class B Common
Stock (all without interest).

                 (g)      NO LIABILITY.  Neither Parent, Heftel, Heftel Sub,
Tichenor, the Surviving Corporation, the Exchange Agent nor any other Person
shall be liable to any former holder of Tichenor securities for any amount
properly delivered to any public official pursuant to any applicable abandoned
property, escheat or similar law.  Any amounts remaining unclaimed by former
holders of Tichenor Common Stock, Tichenor Junior Preferred, Tichenor Senior
Preferred or the Tichenor Warrant, if outstanding as of the Effective Time, for
a period of three years following the Effective Time (or such earlier date
immediately prior to the time at which such amounts would otherwise escheat to
or become property of any governmental entity) shall, to the extent permitted
by applicable law, become the property of Heftel, free and clear of any claims
or interest of any such holders or their successors, assigns or personal
representatives previously entitled thereto.

                 (h)      LOST, STOLEN, OR DESTROYED TICHENOR CERTIFICATES.  If
any Tichenor Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming such Tichenor
Certificate to be lost, stolen or destroyed and, if required by Heftel, the
posting by such Person of a bond, in such reasonable amount as Heftel may
direct, as indemnity against any claim that may be made against it with respect
to such Tichenor Certificate, the Exchange Agent shall issue in exchange for
such lost, stolen or destroyed Tichenor Certificate the shares of Heftel Common
Stock (along with any cash in lieu of fractional shares pursuant to Section
2.5(e) and any unpaid dividends and distributions pursuant to Section 2.5(c))
or cash (with respect to Tichenor Senior Preferred) deliverable with respect
thereto pursuant to this Agreement.

                 (i)      EXCHANGE AT CLOSING.  Notwithstanding the provisions
of Section 2.5(b), each record holder of a Tichenor Certificate who surrenders
such Tichenor Certificate for cancellation to the Surviving Corporation at the
Closing, together with a duly executed letter of transmittal (which shall be
available at the Closing), shall be entitled to receive in exchange therefor
(i) cash in the amount such holder has the right to receive pursuant to Section
2.4(b)(ii), payable in cash or by wire transfer of immediately available funds
on the Closing Date, or (ii) certificates representing Heftel Common Stock in
the amount such holder has the right to receive pursuant to Section 2.4(b)(i),
(iii), (v) or (vi).

         2.6     CLOSING.  The Closing shall take place on the Closing Date at
such time and place as is agreed upon by Heftel and Tichenor.

         2.7     EFFECTIVE TIME OF THE MERGER.  The Merger shall become
effective immediately when a Certificate of Merger is issued by the Secretary
of State of Texas or at such time thereafter as is provided in the Articles of
Merger (the "EFFECTIVE TIME").  As soon as practicable after the Closing, the
Articles of Merger shall be filed, and the Effective Time shall occur, on the
Closing Date; provided, however, that the Articles of Merger may be filed prior
to the Closing Date or prior to the Closing so long as it provides for an
effective time that occurs on the Closing Date immediately after the Closing.

         2.8     TAKING OF NECESSARY ACTION; FURTHER ACTION.  Subject to the
provisions of Section 8.9, each of Parent, Heftel, Heftel Sub and Tichenor
shall use all reasonable efforts to take all such actions as may be necessary
or appropriate in order to effectuate the Merger under the TBCA as promptly as
commercially practicable.  If, at any time after the Effective Time, any
further action is necessary or desirable to carry out the purposes of this
Agreement and to vest the Surviving Corporation with full right, title and
possession to all assets, property, rights, privileges, powers and franchises
of  either of Heftel Sub or Tichenor, the officers and directors of the
Surviving Corporation are fully authorized, in the name of the Surviving
Corporation or otherwise to take, and shall take, all such lawful and necessary
action.

Tichenor or the consummation by Tichenor of the transactions contemplated

all of the licenses, permits and authorizations from the FCC that are necessary
or required for and/or used in the business and operations of the Tichenor

not have a Material Adverse Effect on Tichenor.  The Tichenor FCC Licenses are
valid and in full force and effect through the dates set forth in the
DISCLOSURE LETTER unimpaired by any condition which could have a Material
Adverse Effect on Tichenor.  Except as set forth in the DISCLOSURE LETTER, no
application, action or proceeding is pending for the renewal or modification of
any of the Tichenor FCC Licenses, and, except for actions or proceedings
affecting radio broadcast stations generally, no application, complaint, action
or proceeding is pending or, to Tichenor's knowledge, threatened that may
result in the (i) denial of an application for renewal, (ii) the revocation,
modification, non-renewal or suspension of any of the Tichenor FCC Licenses,
(iii) the issuance of a cease- and-desist order or (iv) the imposition of any
administrative or judicial sanction with respect to any of the Tichenor
Stations.

relating to Tichenor or the Tichenor Stations that might cause the FCC to have

the Tichenor FCC Licenses in the ordinary course.

then outstanding and (ii) no Alien or Aliens are entitled to vote or direct or
control the vote of more than 25% of (A) the total number of shares of capital

nationally recognized firm of investment bankers or financial advisors selected
by Heftel (which opinion shall be acceptable in form and substance to Heftel)
to the effect that the Merger consideration to be paid by Heftel is fair to the
Heftel stockholders from a financial point of view, and such opinion shall not
have been withdrawn, revoked or modified.

                 (b)      Heftel and Tichenor shall have received a letter from
a nationally recognized firm of independent public accountants, dated as of the

to Heftel and Tichenor, in connection with such accountants' review of certain
financial and accounting matters contained in the Proxy Statement/Prospectus
and the Registration Statement.

         5.7     TICHENOR SHAREHOLDERS MEETING.  Tichenor shall take all
necessary action in accordance with applicable law and its articles of
incorporation and bylaws to convene a meeting of its shareholders as promptly

prepare the Registration Statement, and Heftel shall file the Registration
Statement with the SEC as soon as practicable after the execution and delivery
of the Assignment Agreement and in any event not later than 45 days after such

Heftel), to have the Registration Statement declared effective under the
Securities Act as promptly as practicable after such filing.  Heftel shall use
its reasonable efforts, and Tichenor shall cooperate with Heftel to obtain all
necessary





                                       39
<PAGE>   43
state securities laws or "blue sky" permits, approvals and registrations in
connection with the issuance of Heftel Common Stock pursuant to the Merger.

                 (b)      Heftel and Tichenor will cause the Registration

effective under the Securities Act, to comply as to form in all material
respects with the applicable provisions of the Securities Act, the Exchange Act
and the rules and regulations of the SEC thereunder.

                 (c)      Tichenor hereby covenants and agrees with Parent and
Heftel that (i) the Registration Statement (at the time it becomes effective
under the Securities Act and at the Effective Time) will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading
(provided, however, that this clause (i) shall apply only to information
contained in the Registration Statement that was supplied by Tichenor
specifically for inclusion therein); and (ii) the Proxy Statement/Prospectus
(at the time it is first mailed to stockholders of Heftel, at the time of the
Heftel Meeting, and at the Effective Time) will not contain an untrue statement

circumstances under which they are made, not misleading (provided, however,
that this clause (ii) shall apply only to information contained in the

specifically for inclusion in the Registration Statement, occurs and such event
is required to be described in an amendment to the Registration Statement,
Tichenor shall promptly notify Heftel of such occurrence and shall cooperate
with Heftel in the preparation and filing of such amendment.  If, at any time
prior to the Effective Time, any event with respect to Tichenor, or with
respect to other information included in the Proxy Statement/Prospectus, occurs
and such event is required to be described in a supplement to the Proxy
Statement/Prospectus, such event shall be so described and such supplement
shall be promptly prepared, filed and disseminated.

                 (d)      Heftel, upon consummation of the Assignment
Agreement, covenants and agrees with Tichenor that (i) the Registration
Statement (at the time it becomes effective under the Securities Act and at the
Effective Time) will not contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading (provided, however, that this clause (i)
shall not apply to any information contained in the Registration Statement that
was supplied by Tichenor specifically for inclusion therein); and (ii) the
Proxy Statement/Prospectus (at the time it is first mailed to shareholders of
Heftel, at the time of the Heftel Meeting, and at the Effective Time) will not
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading (provided, however, that this clause (ii) shall not apply to any
information contained in the Registration Statement that was supplied by
Tichenor specifically for inclusion therein).  If, at any time prior to the
Effective Time, any event with respect to Heftel, or with respect to other
information included in the Registration Statement, occurs and such event is
required to be described in an amendment to the Registration Statement, such
event shall be so described and such amendment shall be promptly prepared and
filed.  If, at any time prior to the Effective Time, any event with respect to
Heftel, or with respect to other





                                       40
<PAGE>   44
information supplied by Heftel specifically for inclusion in the Proxy
Statement/Prospectus, occurs and such event is required to be described in a
supplement to the Proxy Statement/Prospectus, Heftel shall promptly notify
Tichenor of such occurrence and shall prepare, file and disseminate such
supplement.

                 (e)      Heftel shall use its reasonable efforts to advise
Tichenor, promptly after it receives notice thereof, of the time when the
Registration Statement has become effective under the Securities Act, the
issuance of any stop order with respect to the Registration Statement, the
suspension of the qualification of the Heftel Common Stock issuable in
connection with the Merger for offering or sale in any jurisdiction, or any
comments or requests for additional information by the SEC with respect to the
Registration Statement.

Heftel Common Stock to be issued in the Merger to be approved for listing on
Nasdaq, subject to official notice of issuance, prior to the Closing Date.

         5.10    ADDITIONAL ARRANGEMENTS.  Subject to the terms and conditions
herein provided, each of Parent, Tichenor and Heftel shall take, or cause to be

appropriate or desirable under the HSR Act, the Communications Act and any
other applicable laws and regulations or under applicable governing agreements

desirable to cause the covenants and conditions applicable to the transactions
contemplated hereby to be performed or satisfied as soon as practicable,
including all filings and approvals required by the FCC and the Communications
Act.  If Closing does not occur within 20 days after the date of the FCC's
Final Order, each of Parent, Heftel and Tichenor agree to request approval from
the FCC to extend the Closing so that the Closing contemplated hereunder will
not violate any FCC rules or regulations.  In addition, if any Governmental
Authority shall have issued any order, decree, ruling or injunction, or taken
any other action that would have the effect of restraining, enjoining or
otherwise prohibiting or preventing the consummation of the transactions
contemplated hereby, each of Tichenor and Heftel shall use its reasonable
efforts to have such order, decree, ruling or injunction or other action
declared ineffective as soon as practicable.  Nothing contained in this

list identifying all Persons who, at the time of the approval of this Agreement
and the Merger by the shareholders of Tichenor, may be deemed to be
"affiliates" of Tichenor as that term is used in paragraphs (c) and (d) of Rule
145 under the Securities Act.  Tichenor shall use its best efforts to cause
each Person who is identified as an affiliate of Tichenor in such list to
execute and deliver to Heftel, on or prior to the Closing Date, a written
agreement, in the form attached hereto as EXHIBIT 5.11 (if such Person has not
executed and delivered an agreement substantially to the same effect

by applicable law; and provided further, that Tichenor, Parent or Heftel may
respond to inquiries by the press or others regarding the transactions
contemplated by this Agreement, so long as such responses are consistent with
such party's previously issued press releases.

notice to Parent (or Heftel after consummation of the Assignment Agreement) of
(a) any representation or warranty contained in Article 3 being untrue or

                 (d)      INDEMNIFICATION PROCEDURES.  The procedures
associated with the indemnification set forth in Sections 5.19(b) and (c) shall
be as follows:

                          (i)     Promptly after receipt by an Indemnified
                 Party of notice of the commencement of any action, suit or
                 proceeding, such Indemnified Party shall, if a claim in
                 respect of Section 5.19(b) or (c) is to be made against Parent
                 or Heftel, as the case may be (the "INDEMNIFYING PARTY"),
                 under this Agreement, notify the Indemnifying Party of the
                 commencement thereof.  With respect to any such action, suit
                 or proceeding as to which an Indemnified Party notifies the
                 Indemnifying Party of the commencement thereof:

                          (A)     Except as otherwise provided below, to the
                          extent that it may wish, the Indemnifying Party shall
                          be entitled to assume the defense thereof and to
                          employ counsel chosen by it.  After notice from the
                          Indemnifying Party to the Indemnified Party of its
                          election to so assume the defense thereof, the
                          Indemnifying Party shall not be liable to the
                          Indemnified Party under this Agreement for any legal
                          or other expenses subsequently incurred by the
                          Indemnified Party in connection with the defense
                          thereof other than reasonable costs of investigation
                          or as otherwise provided below.  The Indemnified
                          Party shall have the right to employ counsel of his
                          or its own choosing in such action, suit or
                          proceeding but the fees and expenses of such counsel
                          incurred after notice from the Indemnifying Party of
                          assumption by the Indemnifying Party of the defense
                          thereof shall be at the expense of the Indemnified
                          Party unless (x) the employment of counsel by the
                          Indemnified Party has been specifically authorized by
                          the Indemnifying Party, such authorization to be
                          conclusively established by action by disinterested
                          members of the board of directors of the Indemnifying
                          Party; (y) representation by the same counsel of both
                          the Indemnified Party and the Indemnifying Party
                          would, in the reasonable judgment of either of the
                          Indemnified Party or the Indemnifying Party, be
                          inappropriate due to an actual or potential conflict
                          of interest between the Indemnifying Party and the
                          Indemnified Party in the conduct of the defense of
                          such action, such conflict of interest to be
                          conclusively established by an opinion of counsel to
                          either the Indemnifying Party or the Indemnified
                          Party to such effect; or (z) the Indemnifying Party
                          shall not in fact have employed counsel to assume the
                          defense of such action, in each of which cases the
                          fees and expenses of counsel shall be paid by the
                          Indemnifying Party.  Notwithstanding the foregoing,

                          directors' and officers' liability insurance covering
                          an action, suit or proceeding, then such insurance
                          company shall employ counsel to conduct the defense
                          of such action, suit or proceeding unless the
                          Indemnified Party and the Indemnifying Party
                          reasonably concur in writing that such counsel is 
                          unacceptable.

                          (B)     The Indemnified Party shall cooperate with
                          the Indemnifying Party in all aspects of the conduct
                          of the defense of any action and in connection
                          therewith shall, among other things, make its books,
                          records, executive officers, representatives and
                          agents available as reasonably requested or required

                          (C)     The Indemnifying Party shall not be liable to
                          indemnify the Indemnified Party under Section 5.19(b)

                          action or claim effected without its written consent.
                          The Indemnifying Party may settle any action or claim
                          without the consent of the Indemnified Party provided
                          that such settlement would not impose any liability,
                          penalty or limitation on the Indemnified Party and
                          that the parties bringing such claim release the
                          Indemnified Party from all liability relating to such
                          claim in connection with such settlement.  Neither
                          the Indemnifying Party nor the Indemnified Party
                          shall unreasonably withhold consent to any proposed
                          settlement.

                          (ii)    The Indemnifying Party shall not be liable to
                 make any payment under Sections 5.19(b) or (c) of this
                 Agreement in connection with any action, suit or proceeding
                 against the Indemnified Party to the extent the Indemnified
                 Party has otherwise received payment of the amounts otherwise
                 payable by the Indemnifying Party hereunder.

                          (iii)   In the event the Indemnifying Party makes any
                 payment under this Agreement, the Indemnifying Party shall be
                 subrogated, to the extent of such payment, to all rights of
                 recovery of the Indemnified Party with respect thereto, and
                 the Indemnified Party shall execute all agreements,
                 instruments, certificates or other documents and do or cause
                 to be done all things necessary or appropriate to secure such
                 recovery rights to the Indemnifying Party including, without
                 limitation, executing such documents as shall enable the
                 Indemnifying Party to bring an action or suit to enforce such
                 recovery rights.

                          (iv)    The provisions of this Section 5.19 are
                 intended to be for the benefit of, and shall be enforceable
                 by, the parties hereto and each Indemnified Party and their
                 respective Affiliates and each of their respective heirs and
                 representatives.

the consummation of the transactions contemplated hereby by Tichenor, Parent,
Heftel and Heftel Sub shall have been made or obtained (as the case may be),
except where the failure to obtain such consents, approvals, permits and

by Parent and its Affiliates is more than 90% of the Heftel Common Stock then
outstanding;

                 (g)      By Tichenor if, prior to consummation of the

         7.2     EFFECT OF TERMINATION.  If this Agreement is terminated by
either Tichenor or Parent (or Heftel after consummation of the Assignment
Agreement) pursuant to the provisions of Section 7.1, this Agreement shall
forthwith become void except for, and there shall be no further obligation on
the part of any party hereto or its respective Affiliates, directors, officers,
or shareholders, except pursuant to, the provisions of Sections 5.4(i), 5.14,

parties hereto (which shall continue pursuant to their terms).  The parties
acknowledge that the sole and exclusive remedy of any party to this Agreement
with respect to a breach of a representation or warranty contained herein shall
be the right to terminate this Agreement in accordance with and subject to the
provisions of this Section 7; provided, however, that a termination of this
Agreement shall not relieve any party hereto from any liability for damages
incurred as a result of a breach by such party of its covenants hereunder
occurring prior to such termination other than those covenants contained in
Sections 5.1(c), 5.2(j) and 5.3(j), and the provisions of Section 5.13
regarding notification of inaccuracies with respect to representations and
warranties and the occurrence events or developments that could cause (or could
reasonably be expected to cause) any representation or warranty contained in
this Agreement to be untrue or inaccurate on the Closing Date.  Each party
hereby covenants never to institute, directly or indirectly, any action or
proceeding of any kind against any other party hereto based on or arising out
of, or in any manner related to, the breach of a representation or warranty
contained herein or the covenants contained in Sections 5.1(c), 5.2(j) or
5.3(j) or the provisions of Sections 5.13 referenced in the immediately
preceding sentence.

hereto at any time before or after approval of the Merger and this Merger
Agreement by the shareholders of Tichenor; provided, however, that after any
such approval, no amendment shall be made that by law requires further approval
by such shareholders without such further approval.  This

         8.4     COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and

invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without

provisions of this Agreement in any other jurisdiction.  If any provision of
this Agreement is so broad as to be unenforceable, such provision shall be

         8.6     ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES.  This
Agreement (together with the confidentiality agreements and the documents and
instruments delivered by the parties in connection with this Agreement) (a)
constitutes the entire agreement and supersedes all other prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof; and (b) except as provided in Article 2 and Section
5.19, is solely for the benefit of the parties hereto and their respective
successors, legal representatives and permitted assigns and does not confer on
any other person any rights or remedies hereunder.  Furthermore, Heftel and
Heftel Sub shall have no rights or obligations under this Agreement until such
time as the Assignment Agreement has been consummated.

         8.7     APPLICABLE LAW.  THIS AGREEMENT SHALL BE GOVERNED IN ALL

LAWS OF THE STATE OF TEXAS REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN
UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.

         8.8     NO REMEDY IN CERTAIN CIRCUMSTANCES.  Each party agrees that,
should any court or other competent authority hold any provision of this
Agreement or part hereof to be null, void or unenforceable, or order any party
to take any action inconsistent herewith or not to take an action consistent
herewith or required hereby, the validity, legality and enforceability of the
remaining provisions and obligations contained or set forth herein shall not in
any way be affected or impaired thereby, unless the foregoing inconsistent
action or the failure to take an action constitutes a material breach of this
Agreement or makes this Agreement impossible to perform, in which case this
Agreement shall terminate pursuant to Article 7.  Except as otherwise
contemplated by this Agreement, to the extent that a party hereto took an
action inconsistent herewith or failed to take action consistent herewith or
required hereby pursuant to an order or judgment of a court or other competent
Governmental Authority, such party shall not incur any liability or obligation
unless such party breached its obligations under Section 5.9 or did not in good
faith seek to resist or object to the imposition or entering of such order or
judgment.

         8.9     ASSIGNMENT.

                 (a)      ASSIGNMENT BY TICHENOR.  Neither this Agreement nor
any of the rights, interests or obligations hereunder shall be assigned by
Tichenor (whether by operation of law or otherwise) without the prior written
consent of the other parties.

                 (b)      ASSIGNMENT BY PARENT.  Within ten (10) business days
of the consummation of the Heftel Acquisition, Parent shall submit this
Agreement to Heftel and Heftel Sub for approval and execution of an agreement
in the form attached hereto as EXHIBIT 8.9 (the "ASSIGNMENT AGREEMENT")
pursuant to which Heftel and Heftel Sub will agree that the terms and
provisions of this Agreement relating to them shall be binding upon them as if
Heftel and Heftel Sub were original parties to this Agreement.  Promptly after
such submission, the board of directors of each of Heftel and Heftel Sub shall,
in their own independent exercise of their respective fiduciary obligations,
either approve the Merger and submit the Heftel Proposal to the stockholders of
Heftel for approval and the Merger and this Agreement to the shareholders of
Heftel Sub for their approval, or reject the Merger, in which case this
Agreement shall terminate without liability to any party hereto except to the
extent expressly otherwise provided herein.  Subject to the boards of directors
of Heftel and Heftel Sub exercising their respective fiduciary obligations with
respect to their approval or rejection of the Merger, the exercise of which
shall be made solely by such boards of directors, Parent shall use its
reasonable efforts to cause Heftel and Heftel Sub to consummate the Merger.
Upon execution of the Assignment Agreement by Heftel and Heftel Sub, all
parties hereto shall be deemed to have accepted the assumption of obligations
and rights by Heftel and Heftel Sub and no other action on the part of any such
party is intended to be required; provided that all parties hereto shall
execute such instruments and otherwise provide such cooperation as shall
reasonably be requested by Parent to implement such assignment.  Subject to the
foregoing, this Agreement will be binding upon, inure to the benefit of and be
enforceable by the parties and their respective successors and permitted
assigns.

                          CERTIFICATE OF INCORPORATION

                                       OF

                        HEFTEL BROADCASTING CORPORATION


         1.      Name. The name of the Corporation is Heftel Broadcasting
Corporation.

         2.      Registered Office.  The address of its registered office in
the State of Delaware is Corporation Trust Center, 1209 Orange Street, in the
City of Wilmington, County of New Castle. The name of its registered agent at
such address is The Corporation Trust Company.

         3.      Business.  The nature of the business or purpose of the
Corporation is to engage in any lawful act or activity for which corporations
may be organized under the General Corporation Law of Delaware.

         4.      Capital Structure.

                 4.1      Authorized Shares.  The total number of shares of
capital stock which the Corporation shall have authority to issue is
105,000,000 shares, consisting of three classes of capital stock:

                          (a)     50,000,000 shares of Class A Common Stock,
par value $.001 per share (the "Class A Shares");

                          (b)     50,000,000 shares of Class B Common Stock,
par value $.001 per share (the "Class B Shares" and, together with the Class A
Shares, the "Common Shares"); and

                          (c)     5,000,000 shares of Preferred Stock, par
value $.001 per share (the "Preferred Stock").

                 4.2      Designations, Preferences, etc.

                          (a)     Preferred Stock.  The Preferred Stock may be
issued in one or more series.  The provisions of this Paragraph 4.2 are subject
to the provisions of Paragraph 5.10 hereof.  The Corporation's Board of
Directors is authorized, subject to limitations prescribed by law, to provide
for the issuance of the shares of Preferred Stock in series, and by filing a
certificate pursuant to the applicable law of the State of Delaware, to
establish from time to time the number of shares to be included in each such
series, to determine the powers, designations, preferences and relative,
participating, optional or other special rights, including voting rights, and
the qualifications, limitations or restrictions thereof, of each series of
Preferred Stock and may increase or decrease the number of shares within each
such series; provided, however, that the Corporation's Board of Directors may
not decrease the number of
<PAGE>   60
shares within a series to less than the number of shares within such series
that are then outstanding and may not increase the number of shares within a
series above the total number of authorized shares of Preferred Stock for which
the powers, designations, preferences and rights have not otherwise been set
forth herein.  The authority of the Board of Directors with respect to each
series shall include, but not be limited to, determination of the following:

                          (i)     The number of shares constituting that series
and the distinctive designation of that series;

                          (ii)    The dividend rate on the shares of that
series, whether dividends shall be cumulative, and, if so, from which date or
dates, and the relative rights of priority, if any, of payment of dividends on
shares of that series;

                          (iii)   Whether that series shall have voting rights,
in addition to the voting rights provided by law, and, if so, the terms of such
voting rights;

                          (iv)    Whether that series shall have conversion
privileges, and, if so, the terms and conditions of such conversion, including
provision for adjustment of the conversion rate in such events as the Board of
Directors shall determine;

                          (v)     Whether or not the shares of that series
shall be redeemable, and if so, the terms and conditions of such redemption,
including the date or date upon or after which they shall be redeemable, and
the amount per share payable in case of redemption, which amount may vary under
different conditions and at different redemption dates;

                          (vi)    Whether that series shall have a sinking fund
for the redemption or purchase of shares of that series, and, if so, the terms
and amount of such sinking fund; and

                          (vii)   The rights of the shares of that series in
the event of voluntary or involuntary liquidation, dissolution or winding up of
the Corporation, and the relative rights of priority, if any, of payment of
shares of that series.

                          (b)     Common Shares.  The designations,
preferences, powers, qualifications and privileges of the Common Shares shall
be as set forth in Article Five below.

         5.      Common Shares.

                 5.1      Identical Rights.  Except as herein otherwise
expressly provided in this Article Five, all Common Shares shall be identical
and shall entitle the holders thereof to the same rights and privileges.

                 5.2      Dividends.

                          (a)     When, as, and if dividends are declared by
the Corporation's Board of Directors, whether payable in cash, property,
securities or rights of the Corporation or any other entity, the holders of
Common Shares shall be entitled to share equally in and to receive, in
accordance with the number of Common Shares held by each such holder, all such
dividends, except that if dividends are payable in Common Shares, such stock
dividends shall be payable
<PAGE>   61
at the same rate on each class of Common Shares and shall be payable only in
Class A Shares to holders of Class A Shares and in Class B Shares to holders of
Class B Shares.

                          (b)     Dividends payable under this Paragraph 5.2
shall be paid to the holders of record of the outstanding Common Shares as
their names shall appear on the stock register of the Corporation on the record
date fixed by the Board of Directors in advance of declaration and payment of
each dividend. Any Common Shares issued as a dividend pursuant to this
Paragraph 5.2 shall, when so issued, be duly authorized, validly issued, fully
paid and non- assessable, and free of all liens and charges. The Corporation
shall not issue fractions of Common Shares on payment of such dividend but
shall issue a whole number of shares to such holder of Common Shares rounded up
or down in the Corporation's sole discretion to the nearest whole number,
without compensation to the stockholder whose fractional share has been rounded
down or from any stockholder whose fractional share has been rounded up.

                 5.3      Stock Splits.  The Corporation shall not in any
manner subdivide (by any stock split, reclassification, stock dividend,
recapitalization or otherwise) or combine the outstanding shares of one class
of Common Shares unless the outstanding shares of all classes of Common Shares
shall be proportionately subdivided or combined.

                 5.4      Liquidation Rights.  Upon any voluntary or
involuntary liquidation, dissolution or winding-up of the affairs of the
Corporation, after payment shall have been made to holders of outstanding
Preferred Stock, if any, of the full amount to which they are entitled pursuant
to this Second Restated Certificate of Incorporation and any resolutions that
may be adopted from time to time by the Corporation's Board of Directors (for
the purpose of fixing the designations, preferences, rights and restrictions of
any series of Preferred Stock), the holders of Common Shares shall be entitled
to share ratable in accordance with the number of Common Shares held by each
such holder, in all remaining assets of the Corporation available for
distribution among the holders of Common Shares, whether such assets are
capital, surplus or earnings. For purposes of this Paragraph 5.4, neither the
consolidation or merger of the Corporation with or into any other corporation
or corporations pursuant to which the stockholders of the Corporation receive
capital stock and/or other securities (including debt securities) of the
acquiring corporation (or of the direct or indirect parent corporation of the
acquiring corporation), nor the sale, lease or transfer by the Corporation of
all or any part of its assets, nor the reduction of the capital stock of the
Corporation, shall be deemed to be a voluntary or involuntary liquidation,
dissolution or winding up of the Corporation as those terms are used in this
Paragraph 5.4.

                 5.5      Voting Rights.  The holders of the Class A Shares
shall vote on all matters submitted to a vote of the stockholders, with each
Class A Share entitled to one vote. The holders of Class B Shares shall have no
voting rights, except as provided in Paragraph 5.10 and as otherwise provided
by law. The holders of Common Shares are not entitled to cumulate votes in the
election of any directors.

                 5.6      No Preemptive or Subscription Rights.  No holder of
Common Shares shall be entitled to preemptive or subscription rights.

                 5.7      Conversion Rights.

<PAGE>   62
                          (a)     Automatic Conversion of Class B Shares.  Each
Class B Share shall convert automatically into one fully paid and
non-assessable Class A Share upon its sale, gift or other transfer to a person
or entity other than Clear Channel Communications, Inc., a Texas corporation
("CCC") or an Affiliate of CCC (an "Event of Automatic Conversion").  For
purposes of this Article 5, an "Affiliate of CCC" shall mean (i) any
corporation of which CCC is, directly or indirectly, the beneficial owner of
50% or more of the combined voting power of all classes of equity securities,
(ii) any partnership, joint venture or unincorporated organization for which
CCC possesses, directly or indirectly, the power to direct or cause the
direction of the management and policies, whether through the ownership of
voting securities, by contract or otherwise or (iii) any person or other entity
that controls, is controlled by, or is under common control with CCC.

                          Notwithstanding anything to the contrary set forth
herein, any holder of Class B Common Stock may pledge his shares of Class B
Common Stock to a pledgee pursuant to a bona fide pledge of such shares as
collateral security for indebtedness due to the pledgee without causing an
automatic conversion into Class A Common Stock. In the event of foreclosure or
other similar action by a pledgee, such pledged shares of Class B Common Stock
shall be converted automatically, without any act or deed on the part of the
Corporation or any other person, into shares of Class A Common Stock as
provided in this Paragraph 5.7, unless such foreclosure or similar action is
taken by CCC or an Affiliate of CCC.

                          (b)     Automatic Conversion Procedure.  Promptly
upon the occurrence of an Event of Automatic Conversion, the holder of Class B
Shares shall surrender the certificate or certificates therefor, duly endorsed
in blank or accompanied by proper instruments of transfer, at the office of the
Corporation, or of any transfer agent for the Class A Shares, and shall give
written notice to the Corporation, at such office: (i) stating that the shares
are being converted pursuant to an Event of Automatic Conversion into Class A
Shares as provided in Paragraph 5.7(a), (ii) specifying the Event of Automatic
Conversion (and, if the occurrence of such event is within the control of the
transferor, stating the transferor's intent to effect an Event of Automatic
Conversion), (iii) identifying the number of Class B Shares being converted,
and (iv) setting out the name or names (with addresses) and denominations in
which the certificate or certificates for Class A Shares shall be issued and
shall include instructions for delivery thereof.  Delivery of such notice
together with the certificates representing the Class B Shares shall obligate
the Corporation or its transfer agent to issue and deliver at such stated
address to such stated transferee a certificate or certificates for the number
of Class A Shares to which such transferee is entitled, registered in the name
of such transferee.

                          To the extent permitted by law, conversion pursuant
to an Event of Automatic Conversion shall be deemed to have been effected as of
the date on which the Event of Automatic Conversion occurred (such time being
the "Conversion Time"). The person entitled to receive the Class A Shares
issuable upon such conversion shall be treated for all purposes as the record
holder of such Class A Shares at and as of the Conversion Time, and the right
of such person as a holder of Class B Shares shall cease and terminate at and
as of the Conversion Time, in each case without regard to any failure by the
holder to deliver the certificates or the notice required by this subparagraph
(b).

<PAGE>   63
                          (c)     Voluntary Conversion of Class B Shares.  Each
Class B Share shall be convertible, at the option of its holder, into one fully
paid and non-assessable Class A Share at any time.

                          (d)     Voluntary Conversion Procedure for Class B
Shares.  At the time of a voluntary conversion, the holder of Class B Shares
shall deliver to the office of the Corporation or any transfer agent for the
Class A Shares (i) the certificate or certificates representing the Class B
Shares to be converted, duly endorsed in blank or accompanied by proper
instruments of transfer, and (ii) written notice to the Corporation stating
that such holder elects to convert such share or shares and stating the name
and addresses in which each certificate for Class A Shares is to be issued.
Conversion shall be deemed to have been effected at the close of business on
the date the Corporation received the Class B Shares to be converted and such
notice, and the person exercising such voluntary conversion shall be deemed to
be the holder of record of the number of Class A Shares issuable upon such
conversion at such time. The Corporation shall promptly deliver certificates
evidencing the appropriate number of Class A Shares to the person set forth in
the notice.

                          (e)     Voluntary Conversion of Class A Shares.  Each
Class A Share held by CCC or any Affiliate of CCC shall be convertible, at the
option of its holder, into one fully paid and non-assessable Class B Share at
any time.

                          (f)     Voluntary Conversion Procedure for Class A
Shares.  At the time of a voluntary conversion, the holder of Class A Shares
shall deliver to the office of the Corporation or any transfer agent for the
Class B Shares (i) the certificate or certificates representing the Class A
Shares to be converted, duly endorsed in blank or accompanied by proper
instruments of transfer, and (ii) written notice to the Corporation stating
that such holder elects to convert such share or shares and stating the name
and addresses in which each certificate for Class B Shares is to be issued.
Conversion shall be deemed to have been effected at the close of business on
the date the Corporation received the Class A Shares to be converted and such
notice, and the person exercising such voluntary conversion shall be deemed to
be the holder of record of the number of Class B Shares issuable upon such
conversion at such time. The Corporation shall promptly deliver certificates
evidencing the appropriate number of Class B Shares to the person set forth in
the notice.

                          (g)     Unconverted Shares.  In the event of the
conversion of less than all of the Class B Shares evidenced by a certificate
surrendered to the Corporation in accordance with the procedures of Paragraph
5.7(b) or 5.7(d), the Corporation shall execute and deliver to, or upon the
written order of the holder of such certificate, without charge to such holder,
a new certificate evidencing the number of Class B Shares not converted.  In
the event of the conversion of less than all of the Class A Shares evidenced by
a certificate surrendered to the Corporation in accordance with the procedures
of Paragraph 5.7(f), the Corporation shall execute and deliver to, or upon the
written order of the holder of such certificate, without charge to such holder,
a new certificate evidencing the number of Class A Shares not converted.

                          (h)     Reissue of Shares.  Class B Shares that are
exchanged for Class A Shares as provided herein shall continue to be authorized
Class B Shares and available for reissue by the Corporation as determined by
the Board of Directors.  Class A Shares that are





                                       5
<PAGE>   64
exchanged for Class B Shares as provided herein shall continue to be authorized
Class A Shares and available for reissue by the Corporation as determined by
the Board of Directors.

                          (i)     Reservation.  The Corporation hereby reserves
and shall at all times reserve and keep available, out of its authorized and
unissued Class A Shares, for the purposes of effecting conversions, such number
of duly authorized Class A Shares as shall from time to time be sufficient to
effect the conversion of all outstanding Class B Shares.  The Corporation
hereby reserves and shall at all times reserve and keep available, out of its
authorized and unissued Class B Shares, for the purposes of effecting
conversions, such number of duly authorized Class B Shares as shall from time
to time be sufficient to effect the conversion of all outstanding Class A
Shares.  The Corporation covenants that all the Class A Shares or the Class B
Shares, as the case may be, so issuable shall, when so issued, be duly and
validly issued, fully paid and non-assessable, and free from liens and charges
with respect to the issue.

                 5.8      Consideration on Merger, Consolidation, etc.  In any
merger, consolidation or business combination, the consideration to be received
per share by the holders of Class A Shares and Class B Shares must be identical
for each class of stock, except that in any such transaction in which shares of
common stock are to be distributed, such shares may differ as to voting rights
to the extent that voting rights now differ among the Class A Shares and the
Class B Shares.

                 5.9      Transfer of Class B Shares.  If a holder of Class B
Shares desires to transfer Class B Shares to CCC or an Affiliate of CCC, such
holder shall deliver to the Secretary of the Corporation (a) the certificate or
certificates representing the Class B Shares, duly endorsed in blank or
accompanied by proper instruments of transfer and (b) written notice to the
Corporation stating that such holder elects to transfer such shares and stating
the name and addresses in which each certificate for Class B Shares is to be
issued.  Class B Shares shall not be transferred on the books of the
Corporation until all of the conditions set forth in the foregoing clauses (a)
and (b) are satisfied.

                 5.10     Restrictions and Limitations. So long as CCC and any
Affiliate of CCC collectively own 20% of the outstanding Class A Shares
(calculated as if CCC owns all the Class B Shares subject to that certain
Option Agreement, dated as the closing date of the merger contemplated by the
Agreement and Plan of Merger dated as of July 9, 1996, by and between CCC and
Tichenor Media System, Inc. pursuant to which a subsidiary of the Corporation
was merged with and into Tichenor Media System, Inc., which Option Agreement is
by and between CCC and the Corporation, and that such shares are outstanding,
and treating all such Class B Shares owned, or deemed as owned, by CCC and any
Affiliate of CCC as if they had been converted to outstanding Class A Shares),
the Corporation shall not, and shall not permit any subsidiary to, without the
vote or written consent by the holders of a majority of the Class B Shares
voting as a single class, with each Class B Share entitled to one vote:

                          (a)     Effect any sale, lease, assignment, transfer
or other conveyance of all or substantially all of the assets of the
Corporation, or any merger or consolidation involving the Corporation where the
stockholders of the Corporation immediately prior to such merger or
consolidation do not own at least 50% of the capital stock of the surviving
entity immediately





                                       6
<PAGE>   65
thereafter, or any reclassification or any recapitalization, or any
dissolution, liquidation, or winding up of the Corporation;

                          (b)     Authorize, issue, or obligate itself to 
issue, any shares of Preferred Stock;

                          (c)     Make or permit any amendment to the
Corporation's certificate of incorporation, as amended from time to time, that
adversely affects the rights of the holders of Class B Shares;

                          (d)     Declare or pay any non-cash dividends on or
declare or make any other non-cash distribution, direct or indirect, on account
of the Common Shares or set apart any amount other than cash for any such
purpose; or

                          (e)     Make or permit any amendment or modification
to any Article of the Corporation's certificate of incorporation, as amended
from time to time, concerning the Corporation's capital stock, including, but
not limited to, Article Four or Article Five hereof.

         6.      Existence.  The Corporation is to have perpetual existence.

         7.      Bylaws.  In furtherance and not in limitation of the powers
conferred by statute, the Board of Directors is expressly authorized to make,
alter or repeal the bylaws of the Corporation.

         8.      Elections, Meetings and Books.  Elections of directors need
not be by written ballot unless the bylaws of the Corporation shall so provide.
Meetings of stockholders may be held within or without the State of Delaware,
as the bylaws may provided. The books of the Corporation may be kept (subject
to any provision contained in the statutes) outside the State of Delaware at
such place or places as may be designated from time to time by the board of
directors or in the bylaws of the Corporation.

         9.      Amendment.  The Corporation reserves the right to amend,
alter, change or repeal any provision contained in this Second Amended and
Restated Certificate of Incorporation, in the manner now or hereafter
prescribed by statute, and all rights conferred upon stockholders herein are
granted subject to this reservation.

         10.     Limitation on Director Liability.  No director shall be
personally liable to the Corporation or any of its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability (a)
for any breach of the director's duty of loyalty to the Corporation or its
stockholders, (b) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (c) under Section 174 of
the Delaware General Corporation Law, or (d) for any transaction from which the
director derived an improper personal benefit. If the Delaware General
Corporation Law hereafter is amended to authorize the further elimination or
limitation of the liability of directors, then the liability of a director of
the Corporation, in addition to the limitations on personal liability provided
herein, shall be limited to the fullest extent permitted by the amended
Delaware General Corporation Law. Any repeal or modification of this Article
shall be prospective only, and shall not





                                       7
<PAGE>   66
adversely affect any limitation on the personal liability of a director of the
Corporation existing at the time of such repeal or modification.

         11.     Indemnification.

                 11.1     General.  Each person who was or is made a party to
or threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative, including
a grand jury proceeding and an action by the Corporation (individually, a
"Proceeding") by reason of the fact that he or she, or a person of whom he or
she is the legal representative, is or was a director or officer of the
Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or
agent or in any other capacity while serving as a director, officer, employee
or agent, shall be indemnified and held harmless by the Corporation to the
fullest extent authorized by the Delaware General Corporation Law, as the same
exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than said law permitted the Corporation to
provide prior to such amendment), against all expense, liability and loss
(including attorneys' fees, judgments, fines, excise taxes under the Employee
Retirement Income Security Act of 1974 or penalties and amounts paid or to be
paid in settlement) reasonably incurred or suffered by such person in
connection with the Proceeding (collectively, "Covered Expenses") and such
indemnification shall continue as to the person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of his or
her heirs, executors and administrators; provided, however, that, except as
provided in Paragraph 11.2, the Corporation shall indemnify any such person
seeking indemnification in connection with a Proceeding (or part thereof)
initiated by such person only if such Proceeding (or party thereof) was
authorized by the Board of Directors of the Corporation. The right to
indemnification conferred in this Article shall be a contract right and shall
include the right to be paid by the Corporation the expenses incurred in
defending any such Proceeding in advance of its final disposition; provided,
however, that if required by the Delaware General Corporation Law, the payment
of such expenses incurred by a director or officer in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer, including, without
limitation, service to an employee benefit plan) in advance of the final
disposition of a Proceeding shall be made only upon delivery to the Corporation
of an undertaking, by or on behalf of such director or officer, to repay all
amounts so advanced if it shall ultimately be determined that such director or
officer is not entitled to be indemnified under this Article or otherwise.  The
Corporation may, by action of its Board of Directors, provide indemnification
to employees and agents of the Corporation with the same scope and effect as
the foregoing indemnification of directors and officers.

                 11.2     Failure to Pay Claims.  If a claim under Paragraph
11.1 is not paid in full by the Corporation within thirty (30) days after the
Corporation has received a written claim, the claimant may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim and, if successful in whole or part, the claimant shall be entitled
to be paid also the expense of prosecuting such claim.  It shall be a defense
to any such action (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding in





                                       8
<PAGE>   67
advance of its final disposition when the required undertaking, if any is
required, has been tendered to the Corporation) that the claimant has not met
the standards of conduct which make it permissible under the Delaware General
Corporation Law for the Corporation to indemnify the claimant for the amount
claimed, but the burden of proving such defense shall be on the Corporation.
Neither the failure of the Corporation (including its Board of Directors,
independent legal counsel or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of the claimant
is proper in the circumstances because he or she has met the applicable
standard of conduct set forth in the Delaware General Corporation Law, nor an
actual determination by the Corporation (including its Board of Directors,
independent legal counsel or its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the claimant has not met the applicable standard of conduct.

                 11.3     Not Exclusive.  The right to indemnification and the
payment of expenses incurred in defending a Proceeding in advance of its final
disposition conferred in this Article 11 shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute,
provision of this Second Amended and Restated Certificate of Incorporation,
bylaw, agreement, vote of stockholder or disinterested directors or otherwise.

                 11.4     Insurance.  The Corporation may maintain insurance,
at its expense, to protect itself and any director, officer, employee or agent
of the Corporation or another corporation, partnership, joint venture, trust or
other enterprise against any Covered Expenses, whether or not the Corporation
would have the power to indemnify such person against such expense, liability
or loss under the Delaware General Corporation Law.

                 11.5     Definition of the Corporation.  As used in this
Article, references to "the Corporation" shall include, in addition to the
resulting or surviving corporation, any constituent corporation absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, employees
and agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article with
respect to the resulting or surviving corporation as he would have with respect
to such constituent corporation if its separate existence had continued.

                 11.6     Severability.  If this Article or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the Corporation shall nevertheless indemnify each director, officer, employee
and agent of the Corporation as to any Covered Expenses to the fullest extent
permitted by any applicable portion of this Article that shall not have been
invalidated or by any other applicable law.

         12.     Participation of Non-Citizens.  The following provisions are
included for the purpose of ensuring that control and management of the
Corporation remains with loyal citizens of the United States and/or
corporations formed under the laws of the United States or any of the states of
the United States, as required by the Communications Act of 1934, as the same
may be amended from time to time:

<PAGE>   68
                 12.1     The Corporation shall not issue to "Aliens" (which
term shall include (a) a person who is a citizen of a country other than the
United States; (b) any entity organized under the laws of a government other
than the government of the United States or any state, territory or possession
of the United States; (c) a government other than the government of the United
States or of any state, territory or possession of the United States; and (d) a
representative of, or an individual or entity controlled by, any of the
foregoing), either individually or in the aggregate, in excess of 25% of the
total number of shares of capital stock of the Corporation outstanding at any
time and shall seek not to permit the transfer on the books of the Corporation
of any capital stock to any Alien that would result in Aliens holding in excess
of 25% of the total number of shares of capital stock of the Corporation then
outstanding.

                 12.2     Notwithstanding Paragraph 12.1, no Alien or Aliens
shall be entitled to vote or direct or control the vote of more than 25% of (a)
the total number of shares of capital stock of the Corporation outstanding and
entitled to vote at any time and from time to time, or (b) the total voting
power of all shares of capital stock of the Corporation outstanding and
entitled to vote at any time and from time to time, generally, in the election
of directors.

                 12.3     The Board of Directors of the Corporation shall have
all powers necessary to implement the provisions of this Article 12.

Period") commencing on the date of execution of this Agreement and ending on
the earlier of (a) the Closing Date for the acquisition of the last shares of

                 (a)      In the event the Company shall (i) pay a dividend or
make any other distribution with respect to the Stock in shares of any class or
series of its capital stock, (ii) subdivide its outstanding shares of Stock,
(iii) combine its outstanding Stock into a smaller number of shares, or (iv)
issue any shares of its capital stock in a reclassification of the Stock, the
number of shares of Option Stock not acquired hereunder prior to the record or

or other securities of the Company which the Purchaser would have been entitled
to receive after the happening of any of the events described above had the
Option been exercised in full immediately prior to the happening of such event
or any record date with respect thereto.  The per share exercise price shall be
appropriately adjusted to take account of any such event.  Any adjustments made
pursuant to this Section 2.6 shall become effective immediately after the
effective date of such event retroactive to the record date, if any, for such
event.

Agreement and shall, after such consolidation, merger or sale, entitle the
Purchaser to receive upon exercise the number of shares of capital stock or
other securities or property (including cash) of the Company, or of such person
resulting from such consolidation or surviving such merger or to which such
sale shall be made or of the parent of such person, as the case may be, that
would have been distributable or payable on account of the Option Stock if the
Option had been exercised immediately prior to





                                       3
<PAGE>   72
such merger, consolidation or sale (or, if applicable, the record date
therefor); and in any such case the provisions of this Agreement with respect
to the rights and interests thereafter of the Purchaser shall be appropriately
adjusted by the Company in good faith so as to be applicable, as nearly as may
reasonably be, to the capital stock or other securities or property of the
Company or such person to be so distributed or paid.

                 (c)      Notwithstanding the foregoing, (i) if the Company
merges or consolidates with, or sells all or substantially all of its property
and assets to, another Person and consideration is payable to holders of Stock
in exchange for their Stock in connection with such merger, consolidation or
sale which consists solely of cash, or (ii) in the event of the dissolution,
liquidation or winding up of the Company, then the Purchaser shall be entitled
to receive distributions on the date of such event on an equal basis with
holders of Heftel Class A Common Stock as if the Option had been exercised
immediately prior to such event, less the exercise price (whether or not the
Option is then exercisable) and after such payment the Option shall terminate.

which such shares of New Heftel Class B Common Stock can be converted on the
conditions set forth in the Second Amended and Restated Certificate of
Incorporation of the Company.

         6.3     Certain Representations.  If shares of Option Stock are
acquired other than in an offering registered under the Securities Act of 1933,
as amended (the "Securities Act"), (a) the transferee must certify that such
transferee is an "accredited investor" (as such term is defined in Regulation D
promulgated under the Securities Act) and that such shares of Option Stock were
acquired with investment intent and not with a view to resale and (b) such
shares of Option Stock will be subject to a restrictive stock legend stating
that such shares were not registered under the Securities Act, stating that an
opinion of counsel may be required to transfer such shares.  Upon exercise,
each share of Option Stock issued shall bear the following legend:

         THIS SECURITY IS SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, AND
         OTHER TERMS AND CONDITIONS SET FORTH IN THE STOCKHOLDERS AGREEMENT,
         DATED AS OF _________, 199__, A COPY OF WHICH MAY BE OBTAINED FROM THE

                                  FCC CONSENT

         The obligations of the Purchaser to purchase the Option Stock and pay
the Purchase Price to the Company upon the Purchaser's exercise of the Option
and the Company's obligation to issue the Option Stock to the Purchaser are
subject to obtaining the FCC Consent, if required, prior to Closing.  An
application for FCC Consent shall be made if exercise of the Option to the
extent stated in the Option Notice would increase the total portion of the
common equity of the Company owned by Purchaser or its attributable affiliates
beyond thirty-three percent (33%) and counsel for either the Company or the
Purchaser reasonably requests in good faith that such an application be made in
connection with the purchase of such Option Stock.

                              SPECIFIC PERFORMANCE

         The Parties recognize that if either of them refuses to perform under
the provisions of this Agreement, monetary damages alone would not be adequate
to compensate the aggrieved party.  Each party shall therefore be entitled, in
addition to any other remedies that may be available, including money damages,
to obtain specific performance of the terms of this Agreement.  If any action
is brought to enforce this Agreement, the parties agree to waive the defense
that there is an adequate remedy at law.

                            FORM OF AFFILIATE LETTER


Ladies and Gentlemen:

         I have been advised that, as of the date of this letter, I may be
deemed to be an "affiliate" of Tichenor Media System, Inc. ("TICHENOR"), a
Texas corporation, as that term is defined for purposes of Rules 145(c) and (d)
promulgated by the Securities and Exchange Commission (the "SEC") under the
Securities Act of 1933, as amended (the "SECURITIES ACT").  Pursuant to the
terms of the Agreement and Plan of Merger, dated as of July 9, 1996, between
Tichenor and Clear Channel Communications, Inc. ("PARENT"), a Texas corporation
(as modified by that certain Assignment Agreement, dated __________, 1996,
between Parent and Heftel Broadcasting Corporation ("HEFTEL"), a Delaware
corporation, and ______________ ("HEFTEL SUB"), a Texas corporation), Heftel
Sub will be merged with and into Tichenor (such merger being referred to herein
as the "MERGER" and such agreement being referred to herein as the "MERGER
AGREEMENT").  As a result of the Merger, I may receive shares of Class A Common
Stock, par value $.001 per share, of Heftel (the "HEFTEL COMMON STOCK") in
exchange for shares of Common Stock, par value $1.00 per share, or shares of
Junior Preferred Stock, par value $10.00 per share, of Tichenor.

         I hereby represent and warrant to, and covenant and agree with, Heftel
that, if I receive any Heftel Common Stock as a result of the Merger:

         1.      I will not make any sale, transfer, or other disposition of
the Heftel Common Stock in violation of the Securities Act or the rules and
regulations of the SEC promulgated thereunder.

         2.      I have read this letter and the Merger Agreement and have
discussed their requirements and other applicable limitations on my ability to
sell, transfer, or otherwise dispose of the Heftel Common Stock, to the extent
I believed necessary, with my counsel or counsel for Tichenor.

         3.      I have been advised that the issuance of Heftel Common Stock
pursuant to the Merger has been registered under the Securities Act on a
Registration Statement on Form S-4.  I have also been advised, however, that,
to the extent I am considered an "affiliate" of Tichenor at the time the Merger
Agreement is submitted for a vote of the shareholders of Tichenor, any public
offering or sale by me of any shares of Heftel Common Stock that I receive
pursuant to the Merger will, under current law, require either (a) the further
registration under the Securities Act of any shares of Heftel Common Stock to
be sold by me, (b) compliance with Rule 145 under the Securities Act, or (c)
the availability of another exemption from such registration under the
Securities Act.

         4.      I understand that stop transfer instructions will be given to
Heftel's transfer agent with respect to shares of Heftel Common Stock received
by me pursuant to the Merger and that
<PAGE>   80
a legend substantially as follows will be placed on the certificates for the
shares of Heftel Common Stock issued to me pursuant to the Merger:

     THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO
     WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
     APPLIES.  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE
     TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AS OF
     ___________, 1996, BETWEEN THE REGISTERED HOLDER HEREOF AND HEFTEL
     BROADCASTING CORPORATION, A COPY OF WHICH AGREEMENT IS ON FILE AT THE
     PRINCIPAL OFFICES OF HEFTEL BROADCASTING CORPORATION.

     I also understand that, unless the transfer by me of my Heftel Common
Stock has been registered under the Securities Act or is a sale made in
conformity with the provisions of Rule 145, Heftel reserves the right to put
the following legend on the certificates issued to my transferee:

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND WERE
     ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH
     RULE 145 UNDER THE SECURITIES ACT APPLIES.  THE SHARES HAVE BEEN ACQUIRED
     BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY
     DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT AND MAY NOT
     BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH AN
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

         It is understood and agreed that the legends set forth in this
Paragraph 4 shall be removed by delivery of substitute certificates without
such legends if such legends are not required for purposes of the Securities
Act or this agreement.  It is understood and agreed that such legends referred
to above will be removed if (a) two years shall have elapsed from the date the
undersigned acquired the Heftel Common Stock received in the Merger and the
provisions of Rule 145(d)(2) are then available to the undersigned, (b) three
years shall have elapsed from the date the undersigned acquired the Heftel
Common Stock received in the Merger and the provisions of Rule 145(d)(3) are
then applicable to the undersigned, or (c) Heftel has received either an
opinion of counsel, which opinion and counsel shall be reasonably satisfactory
to Parent, or a "no action" letter obtained from the staff of the SEC, to the
effect that the restrictions imposed by Rule 145 under the Securities Act no
longer apply to the undersigned.  Prior to any transfer of any of the Heftel
Common Stock, I will give written notice to Heftel of my intention to effect
such offer, sale or transfer, describing the proposed transaction in sufficient
detail to enable Heftel and its counsel to determine that the proposed
transaction will not violate the Securities Act.

<PAGE>   81
         Execution of this letter should not be considered an admission on my
part that I am an "affiliate" of Heftel as described in the first paragraph of
this letter or as a waiver of any rights I may have to object to any claim that
I am such an affiliate on or after the date of this letter.

                                        Sincerely,


                                        ----------------------------------------

         2.      Demand Registration.

                 (a)      Request for Registration.  At any time (i) during the
three year period commencing on the Conversion Date or (ii) prior to the
Conversion Date (A) during any period in which less than two million shares of
Common Stock (such number to be appropriately adjusted for stock dividends,
stock splits, recapitalizations and other transactions that affect the
capitalization of the Company) are held of record or beneficially by Public
Stockholders or (B) after the first anniversary of this Agreement and until the
Company has affected a Qualified Offering if the Company has failed prior to
the first anniversary of this Agreement to effect a Qualified Offering
(individually and collectively, the "Demand Registration Period"), any Holder
or Holders of not less than 25% of the then outstanding Registrable Securities
(the "Demand Requesting Holder(s)") may make a written request of the Company
(a "Demand Request") for registration under the Securities Act (a "Demand
Registration") of all or part of its or their Registrable Securities; provided,
however, that the number of Registrable Securities requested to be registered
shall have a Fair Market Value in excess of $20,000,000.  Any Demand
Registration Period may be extended pursuant to Section 4(c).

         The Company shall be obligated to register Registrable Securities (x)
during the period set forth in clause (i) of the first sentence in the first
paragraph of this Section 2(a) on two occasions only, (y) during the period set
forth in clause (ii)(A) of the first sentence in the first paragraph of this
Section 2(a) on one occasion only and (z) during the period from the first
anniversary of this Agreement to the Conversion Date (pursuant to the terms of
Section 2(a)(ii)(B)) on one occasion only; provided, however, upon the
occurrence of the Conversion Date, the Liquidity Event Demand Right and the
Qualified Offering Demand Right, if applicable, shall expire and upon the
exercise of a Liquidity Event Demand Right by the Holders, if applicable, prior
to the exercise of a Qualified Offering Demand, the Qualified Offering Demand
Right shall expire.

         At any time following a Demand Registration by any Demand Requesting
Holder or Holders pursuant to this Section 2, a Demand Requesting Holder or
Holders may make a subsequent Demand Request only if not less than 180 days
(the "Blackout Period") has elapsed from the later of (A) the date of
effectiveness of the prior Demand Registration or (B) the date of effectiveness
of any registration under the Securities Act with respect to an offering of any
equity securities by the Company for its own account or an offering of
securities of the Company initiated by any other holder of demand registration
rights (other than an Exempt Registration Statement).  Notwithstanding the
foregoing, such Holders may make such a subsequent Demand Request during the
Blackout Period in the event that the date of effectiveness of either
registration referred to in the preceding sentence falls within 180 days of the
end of the Demand Registration Period.

         Each Demand Request shall specify the number of shares of Registrable
Securities proposed to be sold. Within ten days after receipt of a Demand
Request, the Company shall give written notice of such registration request to
all Holders of Registrable Securities and all other holders of piggyback





                                      -5-
<PAGE>   87
registration rights (the "Company Notice"). Upon the written request of any
such other Holder, delivered to the Company no later than 15 days after receipt
of the Company Notice by such Holder,  to include all or any portion of the
Registrable Securities of such Holder in the Demand Registration (such Holders,
together with the Demand Requesting Holders, being referred to herein as the
"Requesting Holders"), the Company shall use all commercially reasonable
efforts (subject to Section 2(d)) to cause the managing Underwriter or
Underwriters of a Demand Registration to permit the Registrable Securities
proposed to be sold by the Requesting Holders to be included in such Demand
Registration.  Notwithstanding the foregoing, the Company shall not be required
to include any Registrable Securities of any Requesting Holder in such
registration unless such Requesting Holder accepts the terms of the
underwriting agreement between the Company and the managing Underwriter or
Underwriters and otherwise complies with the provisions of Section 8 below.

                 (b)      Effective Registration and Expenses.  Subject to
Section 4(c), the Company shall file the Demand Registration within 90 days
after receiving a Demand Request (the "Required Filing Date") and shall use all
commercially reasonable efforts to cause the same to be declared effective by
the Commission as promptly as practicable after such filing. A registration
will not count as a Demand Registration until it has become effective (unless
the Requesting Holders withdraw all their Registrable Securities, in which case
such demand will count as a Demand Registration unless the Requesting Holders
pay all Registration Expenses in connection with such withdrawn registration);
provided, that if, after it has become effective, an offering of Registrable
Securities pursuant to a registration is interfered with by any stop order,
injunction or other order or requirement of the Commission or other
governmental agency or court, such registration will be deemed not to have been
effected.

                 (c)      Selection of Underwriters.  The offering of
Registrable Securities pursuant to a Demand Registration shall be in the form
of a "firm commitment" underwritten offering.  The Requesting Holders of a
majority of the shares of Registrable Securities to be registered in a Demand
Registration (the "Majority Requesting Holders") shall select the book-running
managing Underwriter and such additional Underwriters to be used in connection
with the offering; provided, that such selections shall be subject to the
consent of the Company, which consent shall not be unreasonably withheld.

                 (d)      Priority on Demand Registrations. In the event that
the managing Underwriter or Underwriters of a Demand Registration advise the
Requesting Holders in writing that in their opinion the total number of
Registrable Securities proposed to be sold by the Requesting Holders and other
securities proposed to be registered pursuant to the piggyback registration
rights of other holders in such offering is sufficiently large to materially
and adversely affect the price or success of the offering (a "Material Adverse
Effect"), then in such event the securities to be included in such offering
shall be allocated, first to the Requesting Holders pro rata on the basis of
the number of shares of fully-diluted Common Stock requested to be included in
such registration by each such Requesting Holder, and second, to the extent
that any additional securities can, in the opinion of the managing Underwriter
or Underwriters, be sold without any such Material Adverse Effect, pro rata
(based on the number of other securities requested to be included in such
registration by such other





                                      -6-
<PAGE>   88
holders) among the other holders registering securities of the Company.  No
securities to be sold for the account of the Company shall be included in a
Demand Registration.  The Company agrees that in the event the Company grants
any piggyback registration rights to other holders in accordance with the terms
of this Agreement, the agreements granting such other piggyback rights must
provide that upon receipt of the Company Notice such other holders must deliver
a request for registration of their securities no later than 10 days from the
date of receipt of the Company Notice.

         3.      Piggy-Back Registration.

                 (a)      Subject to the provisions of this Agreement, if the
Company proposes to file a registration statement under the Securities Act with
respect to an offering of any equity securities by the Company for its own
account or for the account of any of its equity holders (other than an Exempt
Registration Statement), then the Company shall give written notice of such
proposed filing to the Holders of the Registrable Securities as soon as
practicable (but in no event less than 30 days before the anticipated effective
date of such registration statement), and such notice shall offer the Piggyback
Holders (hereinafter defined) the opportunity to register such number of
Registrable Securities as each Piggyback Holder may request (a "Piggyback
Registration").  Subject to Section 3(b), the Company shall include in each
such Piggyback Registration all Registrable Securities requested to be included
in the registration for such offering by the Holders receiving notice of the
Piggyback Registration (the "Piggyback Holders").  Each Piggyback Holder shall
be permitted to withdraw all or part of such Piggyback Holder's Piggyback
Securities from a Piggyback Registration at any time prior to the effective
date thereof.

                 (b)      The Company shall use all commercially reasonable
efforts to cause the managing Underwriter or Underwriters of a proposed
underwritten offering to permit the Registrable Securities requested to be
included in the registration statement for such offering under Section 3(a)
(the "Piggyback Securities") to be included on the same terms and conditions as
any similar securities included therein.  Notwithstanding the foregoing, the
Company shall not be required to include any Piggyback Holder's Piggyback
Securities in such offering unless such Piggyback Holder accepts the terms of
the underwriting agreement between the Company and the managing Underwriter or
Underwriters and otherwise complies with the provisions of Section 8 below.
Furthermore, if, (i) prior to the Conversion Date or (ii) subsequent to the
Conversion Date and subsequent to the exercise or termination of all demand
registration rights granted to the Holders of Registrable Securities pursuant
to Section 2, the managing Underwriter or Underwriters of a proposed
underwritten offering advise the Company in writing that in their opinion the
total amount of securities, including Piggyback Securities and other securities
proposed to be registered pursuant to similar piggyback registration rights, to
be included in such offering is sufficiently large to cause a Material Adverse
Effect, then in such event the securities to be included in such offering shall
be allocated, first to the party initiating the proposed underwritten offering;
second, to the extent that any additional securities can, in the opinion of
such managing Underwriter or Underwriters, be sold without any such Material
Adverse Effect, pro rata (based on the number of Registrable Securities and
other securities requested to be included in such registration by each
Piggyback Holder or other holder) among the Piggyback Holders and other 
holders registering securities of the Company pursuant to similar piggyback
registration rights; and third, to the extent the Company is not the    


                                      -7-
<PAGE>   89
party initiating such proposed underwritten offering and that any additional
securities can, in the opinion of such managing Underwriter or Underwriters, be
sold without any Material Adverse Effect, to the Company.  If, subsequent to
the Conversion Date, but prior to the exercise or termination of all demand
registration rights granted to Holders of Registrable Securities pursuant to
Section 2, the managing Underwriter or Underwriters of a proposed underwritten
offering advise the Company in writing that in their opinion the total amount
of securities, including Piggyback Securities and other securities proposed to
be registered pursuant to similar piggyback registration rights, to be included
in such offering is sufficiently large to cause a Material Adverse Effect, then
in such event the securities to be included in such offering shall be
allocated, first to the party initiating the proposed underwriter offering;
second, to the extent that any additional securities can, in the opinion of
such managing Underwriter or Underwriters, be sold without any such Material
Adverse Effect, (x) 50% of the total amount of additional securities shall be
allocated to any requesting Piggyback Holders (which allocation shall be
allocated pro rata among the requesting Piggyback Holders based on the number
of Registrable Securities requested to be included in such registration) and
(y) the remaining 50% of the additional securities to be included shall be
allocated pro rata among the requesting Piggyback Holders (excluding the shares
included pursuant to clause (x)) and all other holders of securities proposed
to be registered pursuant to similar piggyback registration rights (based upon
the number of Registrable Securities and other securities requested to be
included in such registration); and third, to the extent the Company is not the
party initiating such proposed underwritten offering and that any additional
securities can, in the opinion of such managing Underwriter or Underwriters, be
sold without any Material Adverse Effect, to the Company.

         4.      Holdback Agreements.

                 (a)      Restrictions on Public Sale by Holder of Registrable
Securities.  Each Holder of Registrable Securities (whether or not such
Registrable Securities are included in a registration statement pursuant
hereto) agrees not to effect any public sale or distribution of Common Stock or
securities convertible into or exchangeable or exercisable for Common Stock,
including a sale pursuant to Rule 144 under the Securities Act, during the 14
days prior to, and during the 180-day period beginning on, the effective date
of a registration statement relating to a firm commitment underwritten public
offering of Common Stock or securities convertible into, or exchangeable or
exercisable for Common Stock, except as part of such registration, if and to
the extent requested by the Company in the case of a nonunderwritten public
offering or if and to the extent requested by the managing Underwriter or
Underwriters in the case of an underwritten public offering.

                 (b)      Restrictions on Public Sale by the Company and
Others.  The Company agrees (i) not to effect any public sale or distribution
of any securities similar to those being registered or any securities
convertible into or exchangeable or exercisable for such securities other than
pursuant to a registation statement on Form S-8 or any successor form, during
the 14 days prior to, and during the 180-day period beginning on, the effective
date of any registration statement which includes Registrable Securities
(unless such sale or distribution is pursuant to such registration statement
pursuant to Section 3(b) or the Holders are participating in such registration
statement pursuant to Section 3, and such offering was initiated by the Company
with respect to the sale of securities by





                                      -8-
<PAGE>   90
the Company) and (ii) that any agreement entered into after the date of this
Agreement pursuant to which the Company issues or agrees to issue any privately
placed securities shall contain a provision under which holders of such
securities agree not to effect any public sale or distribution of any such
securities during the period described in (i) above, including a sale pursuant
to Rule 144 under the Securities Act (except as part of any such registration,
if permitted); provided, however, that the provisions of this paragraph (b)
shall not prevent the conversion or exchange of any securities pursuant to
their terms into or for other securities.

                 (c)      Deferral of Filing.  The Company may defer the filing
(but not the preparation) of a registration statement required by Section 2
until a date not later than 90 days after the Required Filing Date if, at the
time the Company receives the Demand Request, the Company or its subsidiaries
are engaged in confidential negotiations or other confidential business
activities, disclosure of which would be required in such registration
statement (but would not be required if such registration statement were not
filed), and the Board of Directors of the Company determines in good faith that
such disclosure would be materially detrimental to the Company and its
stockholders. A deferral of the filing of a registration statement pursuant to
this Section 4(c) shall be lifted, and the requested registration statement
shall be filed forthwith, if the negotiations or other activities are disclosed
or terminated. In order to defer the filing of a registration statement
pursuant to this Section 4(c), the Company shall promptly, upon determining to
seek such deferral, deliver to each Requesting Holder a certificate signed by
the President of the Company stating that the Company is deferring such filing
pursuant to this Section 4(c).  Within 20 days after receiving such
certificate, the Holders of a majority of the Registrable Securities held by
the Requesting Holders and for which registration was previously requested may
withdraw such request by giving notice to the Company.  If withdrawn, the
Demand Request shall be deemed not to have been made for all purposes of this
Agreement.  The Company may defer the filing of a particular registration
statement pursuant to this Section 4(c) only once.  In the event the Company
shall defer the filing of a registration statement pursuant to this Section
4(c), the applicable Demand Registration Period shall automatically be extended
by the number of days in the period between the Required Filing Date and the
date on which such registration statement is filed with the Commission.

         5.      Registration Procedures.  The Company will, at its expense,
use all commercially reasonable efforts to effect the registration and the sale
of any Registrable Securities under the Securities Act in accordance with the
intended method of disposition thereof as quickly as practicable, and in
connection with any such request, the Company will as expeditiously as
practicable:

                 (a)      prepare and file with the Commission a registration
statement on any form for which the Company then qualifies or which counsel for
the Company shall deem appropriate and which form shall be available for the
sale of the Registrable Securities to be registered thereunder in accordance
with the intended method of distribution thereof, and use all commercially
reasonable efforts and proceed diligently and in good faith to cause such filed
registration statement to become effective under the Securities Act; provided
that before filing a registration statement or prospectus or any amendments or
supplements thereto, the Company will furnish to all Selling Holders and to one
counsel reasonably acceptable to the Company selected by the Selling Holders,
copies of all





                                      -9-
<PAGE>   91
such documents proposed to be filed, which documents will be subject to the
review of such counsel; provided, further, that in connection with a Demand
Registration, the Company shall not file any registration statement or
prospectus, or any amendments or supplements thereto, if the Requesting Holders
who hold a majority of the Registrable Securities covered by such registration
statement, their counsel, or the managing Underwriters shall reasonably object,
in writing, on a timely basis;

                 (b)      prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective pursuant to Section 2 for a period (except as provided in the last
paragraph of this Section 5) of not less than 180 consecutive days or, if
shorter, the period terminating when all Registrable Securities covered by such
registration statement have been sold (but not before the expiration of the
applicable period referred to in Section 4(3) of the Securities Act and Rule
174 thereunder, if applicable) and comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
methods of disposition by the Selling Holders thereof set forth in such
registration statement;

                 (c)      furnish to each such Selling Holder such number of
copies of such registration statement, each amendment and supplement thereto
(in each case including all exhibits thereto), the prospectus included in such
registration statement (including each preliminary prospectus) and such other
documents as such Selling Holder may reasonably request in order to facilitate
the disposition of the Registrable Securities owned by such Selling Holder;

                 (d)      notify the Selling Holders promptly, and (if
requested by any such Person) confirm such notice in writing, (i) when a
prospectus or any prospectus supplement or post-effective amendment has been
filed, and, with respect to a registration statement or any post-effective
amendment, when the same has become effective under the Securities Act and each
applicable state law, (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to a
registration statement or related prospectus or for additional information,
(iii) of the issuance by the Commission of any stop order suspending the
effectiveness of a registration statement or the initiation of any proceedings
for that purpose, (iv) if at any time the representations or warranties of the
Company or any subsidiary contained in any agreement (including any
underwriting agreement) contemplated by Section 5(i) below cease to be true and
correct in any material respect, (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, (vi) of the happening of any event which makes any statement made in
such registration statement or related prospectus or any document incorporated
or deemed to be incorporated therein by reference untrue in any material
respect or that requires the making of any changes in such registration
statement, prospectus or documents so that, in the case of the registration
statement, it will not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, and that in the case of the prospectus,
it will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in light of the





                                      -10-
<PAGE>   92
circumstances under which they were made not misleading and (vii) of the
Company's reasonable determination that a post- effective amendment to a
registration statement would be appropriate;

                 (e)      use every commercially reasonable effort to obtain
the withdrawal of any order suspending the effectiveness of a registration
statement, or the lifting of any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction in the United States, at the earliest practicable moment;

                 (f)      cooperate with the Selling Holders and the managing
Underwriter or Underwriters to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be sold, which
certificates shall not bear any restrictive legends and shall be in a form
eligible for deposit with The Depositary Trust Company; and enable such
Registrable Securities to be registered in such names as the managing
Underwriter or Underwriters may request at least two business days prior to any
sale of Registrable Securities;

                 (g)      use all commercially reasonable efforts to register
or qualify such Registrable Securities as promptly as practicable under such
other securities or blue sky laws of such jurisdictions as any Selling Holder
or managing Underwriter reasonably (in light of the intended plan of
distribution) requests and do any and all other acts and things which may be
reasonably necessary or advisable to enable such Selling Holder or managing
Underwriter to consummate the disposition in such jurisdictions in the United
States of the Registrable Securities owned by such Selling Holder; provided,
that the Company will not be required to (i) qualify generally to do business
in any jurisdiction where it would not otherwise be required to qualify but for
this paragraph (g), (ii) subject itself to taxation in any such jurisdiction or
(iii) consent to general service of process in any such jurisdiction;

                 (h)      use all commercially reasonable efforts to cause such
Registrable Securities to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company to enable the Selling Holder or Selling
Holders thereof to consummate the disposition of such Registrable Securities;

                 (i)      enter into customary agreements (including an
underwriting agreement in customary form) and take such other actions as are
reasonably required in order to expedite or facilitate the disposition of such
Registrable Securities;

                 (j)      make available for inspection by any Selling Holder
of such Registrable Securities, any Underwriter participating in any
disposition pursuant to such registration statement and any attorney,
accountant or other professional retained by any such Selling Holder or
Underwriter (collectively, the "Inspectors"), all financial and other records,
pertinent corporate documents and properties of the Company (collectively, the
"Records") as shall be reasonably necessary to enable them to exercise their
due diligence responsibility, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such Inspectors
in connection with such registration statement.  Records which the Company
determines, in good faith, to be confidential shall not be disclosed by the
Inspectors unless (i) the disclosure of





                                      -11-
<PAGE>   93
such Records is necessary to avoid or correct a misstatement or omission in
such registration statement or (ii) the release of such Records is ordered
pursuant to a subpoena or other order from a court of competent jurisdiction.
Each Selling Holder of such Registrable Securities agrees that information
obtained by it as a result of such inspections shall be deemed confidential and
shall not be used by it as the basis for any market transactions in the
securities of the Company or its affiliates unless and until such is made
generally available to the public.  Each Selling Holder of such Registrable
Securities further agrees that it will, as soon as practicable upon learning
that disclosure of such Records is sought in a court of competent jurisdiction,
give notice to the Company and allow the Company at its expense to undertake
appropriate action to prevent disclosure of the Records deemed confidential;

                 (k)      use all commercially reasonable efforts to obtain a
comfort letter or comfort letters from the Company's independent public
accountants in customary form and covering such matters of the type customarily
covered by comfort letters as the Selling Holders of a majority of the shares
of Registrable Securities being sold or the managing underwriter or
Underwriters reasonably requests;

                 (l)      otherwise use all commercially reasonable efforts to
comply with all applicable rules and regulations of the Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering a period of twelve months, beginning within three
months after the effective date of the registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act;

                 (m)      use all commercially reasonable efforts to cause all
such Registrable Securities to be listed on each securities exchange on which
similar securities issued by the Company are then listed or quoted on any
inter- dealer quotation system on which similar securities issued by the
Company are then quoted;

                 (n)      if any event contemplated by Section 5(d)(vi) above
shall occur, as promptly as practicable prepare a supplement or amendment or
post-effective amendment to such registration statement or the related
prospectus or any document incorporated therein by reference or promptly file
any other required document so that, as thereafter delivered to the purchasers
of the Registrable Securities, the prospectus will not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading; and

                 (o)      cooperate and assist in any filing required to be
made with the NASD and in the performance of any due diligence investigation by
any underwriter, including any "qualified independent underwriter," or any
Selling Holder.

                 The Company may require each Selling Holder to promptly
furnish in writing to the Company such information regarding the distribution
of the Registrable Securities as it may from time to time reasonably request
and such other information as may be legally required in connection with such
registration.  Notwithstanding anything herein to the contrary, the Company
shall have





                                      -12-
<PAGE>   94
the right to exclude from any offering the Registrable Securities of any
Selling Holder who does not comply with the provisions of the immediately
preceding sentence.

                 Each Selling Holder agrees that, upon receipt of any notice
from the Company of the happening of any event of the kind described in Section
5(d)(vi), such Selling Holder will forthwith discontinue disposition of
Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Selling Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 5(d)(vi), and, if so
directed by the Company, such Selling Holder will deliver to the Company all
copies, other than permanent file copies, then in such Selling Holder's
possession, of the most recent prospectus covering such Registrable Securities
at the time of receipt of such notice.  In the event the Company shall give
such notice, the Company shall extend the period during which such registration
statement shall be maintained effective (including the period referred to in
Section 5(b)) by the number of days during the period from and including the
date of the giving of notice pursuant to Section 5(d)(vi) to the date when the
Company shall make available to the Selling Holders of Registrable Securities
covered by such registration statement a prospectus supplemented or amended to
conform with the requirements of Section 5(d)(vi).

         6.      Registration Expenses.  Subject to the provisions in Section
2(b) above with respect to a Demand Registration, in connection with any Demand
Registration or Piggyback Registration, the Company shall pay the following
registration expenses (the "Registration Expenses"): (a) all registration and
filing fees (including, without limitation, with respect to filings to be made
with the NASD), (b) fees and expenses of compliance with securities or blue sky

         7.      Indemnification; Contribution.

                 (a)      Indemnification by the Company.  The Company agrees
to indemnify and hold harmless each Selling Holder, each Person, if any, who
controls such Selling Holder within the





                                      -13-
<PAGE>   95
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act,
and the officers, directors, agents, general and limited partners, and
employees of each Selling Holder and each such controlling person from and
against any and all losses, claims, damages, liabilities, and expenses
(including reasonable costs of investigation) arising out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in
any registration statement or prospectus relating to the Registrable Securities
or in any amendment or supplement thereto or in any preliminary prospectus, or
arising out of or based upon any omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or expenses arise out of, or are based upon, any such
untrue statement or omission or allegation thereof based upon information
furnished in writing to the Company by such Selling Holder or on such Selling
Holder's behalf expressly for use therein; provided, however,  that with
respect to any untrue statement or omission or alleged untrue statement or
omission made in any preliminary prospectus, the indemnity agreement contained
in this paragraph shall not apply to the extent that any such loss, claim,
damage, liability or expense results from the fact that a current copy of the
prospectus was not sent or given to the Persons asserting any such loss, claim,
damage, liability or expense at or prior to the written confirmation of the
sale of the Registrable Securities concerned to such Person if it is determined
that (i) it was the responsibility of such Selling Holder or any Underwriter or
dealer for Selling Holder to provide such person with a current copy of the
prospectus, (ii) such Selling Holder was provided with a current copy of the
prospectus prior to the written confirmation of sale and (iii) such current
copy of the prospectus would have cured the defect giving rise to such lose,
claim, damage, liability or expense.  The Company also agrees to indemnify any
Underwriters of the Registrable Securities, their officers and directors and
each Person who controls such Underwriters on substantially the same basis as
that of the indemnification of the Selling Holders provided in this Section
7(a).

                 (b)      Indemnification by Holder of Registrable Securities.
Each Selling Holder, severally and not jointly, agrees to indemnify and hold
harmless the Company, and each Person, if any, who controls the Company within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act and the officers, directors, agents and employees of the Company
and each such controlling Person to the same extent as the foregoing indemnity
from the Company to such Selling Holder, but only with respect to information
furnished in writing by such Selling Holder or on such Selling Holder's behalf
expressly for use in any registration statement or prospectus relating to the
Registrable Securities.  The liability of any Selling Holder under this Section
7(b) shall be limited to the aggregate cash and property received by such
Selling Holder pursuant to the sale of Registrable Securities covered by such
registration statement or prospectus.

                 (c)      Conduct of Indemnification Proceedings.  If any
action or proceeding (including any governmental investigation) shall be
brought or asserted against any Person entitled to indemnification under
Section 7(a) or 7(b) above (an "Indemnified Party") in respect of which
indemnity may be sought from any party who has agreed to provide such
indemnification under Section 7(a) or 7(b) above (an "Indemnifying Party"), the
Indemnified Party shall give prompt notice to the Indemnifying Party and the
Indemnifying Party shall assume the defense thereof, including the employment
of counsel reasonably satisfactory to such Indemnified Party, and shall assume
the





                                      -14-
<PAGE>   96
payment of all reasonable expenses of such defense. Such Indemnified Party
shall have the right to employ separate counsel in any such action or
proceeding and to participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party unless (i)
the Indemnifying Party has agreed to pay such fees and expenses, or (ii) the
Indemnifying Party fails promptly to assume the defense of such action or
proceeding or fails to employ counsel reasonably satisfactory to such
Indemnified Party or (iii) the named parties to any such action or proceeding
(including any impleaded parties) include both such Indemnified Party and
Indemnifying Party (or an Affiliate of the Indemnifying Party), and such
Indemnified Party shall have been advised by counsel that there is a conflict
of interest on the part of counsel employed by the Indemnifying Party to
represent such Indemnified Party (in which case, if such Indemnified Party
notifies the Indemnifying Party in writing that it elects to employ separate
counsel at the expense of the Indemnifying Party, the Indemnifying Party shall
not have the right to assume the defense of such action or proceeding on behalf
of such Indemnified Party).  Notwithstanding the foregoing, the Indemnifying
Party shall not, in connection with any one such action or proceeding or
separate but substantially similar related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable at any time for the fees and expenses of more than one separate firm of
attorneys (together in each case with appropriate local counsel for the
Indemnified Party).  The Indemnifying Party shall not be liable for any
settlement of any such action or proceeding effected without its written
consent (which consent will not be reasonably withheld), but if settled with
its written consent, or if there be a final judgment for the plaintiff in any
such action of proceeding, the Indemnifying Party shall indemnify and hold
harmless such Indemnified Party from and against any loss or liability (to the
extent stated above) by reason of such settlement or judgment.  The
Indemnifying Party shall not consent to entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release, in form and
substance satisfactory to the Indemnified Party, from all liability in respect
of such action or proceeding for which such Indemnified Party would be entitled
to indemnification hereunder.

                 (d)      Contribution. If the indemnification provided for in
this Section 7 is unavailable to the Indemnified Parties in respect of any
losses, claims, damages, liabilities or judgments referred to herein, then each
such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses, claims, damages, liabilities and judgments as between the
Company on the one band and each Selling Holder on the other, in such
proportion as is appropriate to reflect the relative fault of the Company and
of each Selling Holder in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or judgments, as well as
any other relevant equitable considerations.  The relative fault of the Company
on the one hand and of each Selling Holder on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by such party, and the parties,
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

         The Company and the Selling Holders agree that it would not be just
and equitable if contribution pursuant to this Section 7(d) were determined by
pro rata allocation or by any other





                                      -15-
<PAGE>   97
method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Party as a result of the losses, claims,
damages, liabilities or judgments referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified
Party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7(d), no Selling Holder shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities of such Selling Holder were offered
to the public exceeds the amount of any damages which such selling Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.  No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

         8.      Participation in Underwritten Registrations.  No Holder may
participate in any underwritten registration hereunder unless such Holder (a)
agrees to sell such holder's Registrable Securities on the basis provided in
any underwriting arrangements approved by the Person entitled hereunder to
approve such arrangements, (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements and this
Agreement, and (c) if requested by another Person participating in such
underwritten registration, provides that all securities convertible or
exchangeable into Common Stock that are included in such underwritten
registration shall be so converted or exchanged on or prior to the consummation
thereof.

         9.      Marketing of Securities.  Upon the registration of any
Registrable Securities of any Holders pursuant to the terms of this Agreement,
the Company shall use all commercially reasonable efforts to participate in and
cooperate with the managing Underwriter or Underwriters in the marketing of
such Registrable Securities, including, but not limited to, participating in
any sales force presentations and any "road show" or other marketing
presentations deemed necessary by the managing Underwriter or Underwriters to
market such securities.

         10.     Additional Registration Rights.  The Company shall not on or
after the date of this Agreement enter into any agreement granting registration
rights to any other Person with respect to the securities of the Company, that
are demand registration rights of the type described in Section 2 and do not
rank pari passu or subordinate to the rights granted under Section 2, or with
respect to any piggyback registration rights of the type described in Section
3, that are not pari passu or subordinate to the rights granted to the Holders
of Registrable Securities hereunder (provided, that the recipients of any such
piggyback registration rights shall acknowledge in writing the priority of the
piggyback registration rights granted pursuant to Section 3 during the period
after the Conversion Date, but prior to the exercise or termination of all
demand registration rights granted to the Holders of Registrable Securities
pursuant to Section 2) without the prior written consent of Holders of a
majority of the then outstanding Registrable Securities.  Any agreement entered
into pursuant to such consent shall not be amended without a further written
consent of the Holders of a majority of the then outstanding Registrable
Securities.  The Company represents and warrants to the Holders that the
Company has not granted registration rights to any other Person with respect to
the securities of





                                      -16-
<PAGE>   98
the Company other than pursuant to that certain Registration Rights Agreement
of even date herewith between the Company and Clear Channel Communications,
Inc.

         11.     Amendments and Waivers.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given without the written consent of the Company, Clear Channel (so
long as it and its Affiliates own at least 20% of the Common Stock (calculated
assuming all securities held by Clear Channel and its Affiliates exercisable or
exchangeable for or convertible into Class B Common Stock have been so
exercised, exchanged or converted and the Class B Common Stock subject thereto
is outstanding and by treating the Class B Common Stock of the Company as
converted into Common Stock)) and holders of at least a majority of the then
outstanding Registrable Securities.

         12.     Notices.  Any notices required or permitted to be given under
this Agreement shall be given in writing and shall be deemed received when
received by the relevant party at such party's address as set forth opposite
such party's signature to this Agreement whether personally delivered or sent
by mail or delivered by telefacsimile or similar device.

         13.     Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS.

         14.     Counterparts.  This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.





                                      -17-

         IN WITNESS WHEREOF the parties have caused this Agreement to be
executed by their duly authorized representatives, effective as of the date
first written above.

                                  EXHIBIT 5.16

                              EMPLOYMENT AGREEMENT


         THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into
as of the _______ day of _____________, 1996 by and between Heftel Broadcasting
Corporation, a Delaware corporation (together with its successors and assigns
permitted hereunder, the "Company"), and McHenry T. Tichenor, Jr. (the
"Executive").

         WHEREAS, a wholly-owned subsidiary of the Company  will merge with and
into Tichenor Media System, Inc., a Texas corporation ("Tichenor"), whereby
Tichenor will become a wholly-owned subsidiary of the Company (the "Merger");

         WHEREAS, it is a condition to Tichenor's obligation to consummate the
Merger that the Company enter into this Agreement with the Executive; and

         WHEREAS, the Board of Directors of the Company (the "Board") has
determined that it is in the best interests of the Company and its stockholders
to employ the Executive on the terms and conditions set forth herein.

         NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

         1.      Employment Period.  Subject to Section 3, the Company hereby
agrees to employ the Executive, and the Executive hereby agrees to be employed
by the Company, in accordance with the terms and provisions of this Agreement,
for the period commencing on the effective date of the Merger (the "Effective
Date") and ending on the fifth anniversary of such date (the "Employment
Period").

         2.      Terms of Employment.

                 (a)      Position and Duties.

                          (i)     During the term of the Executive's
employment, the Executive shall serve as Chairman, President and Chief
Executive Officer of the Company and, in so doing, shall report to the Board.
The Executive shall have supervision and control over, and responsibility for,
such management and operational functions of the Company currently assigned to
such position, and shall have such other powers and duties (including holding
officer positions with one or more subsidiaries of the Company) as may from
time to time be prescribed by the Board, so long as such powers and duties are
reasonable and customary for the Chairman, President and Chief Executive
Officer of an enterprise comparable to the Company.
<PAGE>   102
                          (ii)    During the term of the Executive's
employment, and excluding any periods of vacation and sick leave to which the
Executive is entitled, the Executive agrees to devote full business time to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the
Executive's reasonable best efforts to perform faithfully, effectively and
efficiently such responsibilities.  During the term of Executive's employment
it shall not be a violation of this Agreement for the Executive to (A) serve on
corporate, civic or charitable boards or committees, (B) deliver lectures or
fulfill speaking engagements and (C) manage personal investments, so long as
such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement.

                 (b)      Compensation.

                          (i)     Base Salary.  During the term of the
Executive's employment, the Executive shall receive an annual base salary
("Annual Base Salary"), which shall be paid in accordance with the customary
payroll practices of the Company, at least equal to $260,000.  During the term
of the Executive's employment, the Annual Base Salary shall be reviewed at
least annually by the Compensation Committee of the Board (the "Compensation
Committee") and shall be increased at any time and from time to time as the
Compensation Committee shall consider appropriate in accordance with the
compensation practices and guidelines of the Company for its executive
officers.  Any increase in Annual Base Salary shall not serve to limit or
reduce any other obligation to the Executive under this Agreement.  The term
Annual Base Salary as utilized in this Agreement shall refer to Annual Base
Salary as so increased.

                          (ii)    Bonus.  In addition to Annual Base Salary,
the Executive shall be awarded during the term of the Executive's employment
such bonuses (each a "Bonus"), if any, as shall be determined by the
Compensation Committee consistent with its practices for executive officers of
the Company.

                          (iii)   Incentive, Savings and Retirement Plans.
During the term of the Executive's employment, the Executive shall be entitled
to participate in all incentive, savings and retirement plans, practices,
policies and programs applicable generally to other executives of the Company
("Investment Plans").

                          (iv)    Welfare Benefit Plans.  During the term of
the Executive's employment, the Executive and/or the Executive's family, as the
case may be, shall be eligible for participation in and shall receive all
benefits under welfare benefit plans, practices, policies and programs
("Welfare Plans") provided by the Company (including, without limitation,
medical, prescription, dental, disability, salary continuance, employee life,
group life, accidental death and travel accident insurance plans and programs)
to the extent applicable generally to other executives of the Company.

                          (v)     Perquisites.  During the term of the
Executive's employment, the Executive shall be entitled to receive (in addition
to the benefits described above) such perquisites and fringe benefits
appertaining to his position in accordance with any practice established by the
Board and to have the use of the 1993 Chevrolet Suburban owned by the Company.

                          (vi)    Expenses.  During the term of the Executive's
employment, the Executive shall be entitled to receive prompt reimbursement for
all reasonable employment expenses incurred by the Executive in accordance with
the policies, practices and procedures of the Company.

                          (vii)   Vacation and Holidays.  During the term of
the Executive's employment, the Executive shall be entitled to paid vacation
and paid holidays in accordance with the plans, policies, programs and
practices of the Company for its executive officers.

                          (viii)  Employment Credit.  For the purpose of
determining the Executive's eligibility, and the extent of his and  his
family's benefits, under the Investment Plans, the Welfare Plans, and his
rights under clauses (iii), (iv), (v) and (vii) above, the Executive shall be
deemed to have been employed by the Company since the commencement of his
employment with Tichenor.

         3.      Termination of Employment.

                 (a)      Death or Disability.  The Executive's employment
shall terminate automatically upon the Executive's death during the Employment
Period.  If the Disability of the Executive has occurred during the Employment
Period (pursuant to the definition of Disability set forth below), the Company
may give to the Executive written notice in accordance with Section 11(b) of
its intention to terminate the Executive's employment.  In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that, within the 30 days after such receipt, the Executive
shall not have returned to full-time performance of the Executive's duties.
For purposes of this Agreement, "Disability" shall mean the Executive's
incapacity due to mental or physical illness which is determined to be total
and permanent by a physician selected by the Company or its insurers and
acceptable to the Executive or the Executive's legal representative (such
agreement as to acceptability not to be withheld unreasonably).

                 (b)      Cause.  The Company may terminate the Executive's
employment during the Employment Period for Cause or without Cause.  For
purposes of this Agreement, "Cause" shall mean (i) a breach by the Executive of
the Executive's obligations under Section 2(a) (other than as a result of
incapacity due to physical or mental illness) which constitutes a continued
material nonperformance by the Executive of his obligations and duties
thereunder, as determined by the Board, and which is not remedied within 30
days after receipt of written notice from the Company specifying such breach,
(ii) commission by the Executive of an act of fraud upon, or willful misconduct
toward, the Company, as reasonably determined by a majority of the
disinterested




                                      3
<PAGE>   104
members of the Board (neither the Executive nor members of his family being
deemed disinterested for this purpose) after a hearing by the Board following
ten days' notice to the Executive of such hearing, (iii) a material breach by
the Executive of Section 6 or Section 9, or (iv) the conviction of the
Executive of any felony (or a plea of nolo contendere thereto).

                 (c)      Good Reason.  The Executive's employment may be
terminated during the Employment Period by the Executive for Good Reason or
without Good Reason; provided, however, that the Executive agrees not to
terminate his employment for Good Reason unless (i) the Executive has given the
Company at least 30 days' prior written notice of his intent to terminate his
employment for Good Reason, which notice shall specify the facts and
circumstances constituting Good Reason, and (ii) the Company has not remedied
such facts and circumstances constituting Good Reason within such 30 day
period.  For purposes of this Agreement, "Good Reason" shall mean:

                          (i)     the assignment to the Executive of any duties
inconsistent in any respect with the Executive's position (including status,
offices, titles and reporting requirements), authority, duties or
responsibilities as contemplated by Section 2(a) or any other action by the
Company which results in a material diminution in such position, authority,
duties or responsibilities, excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive (without limiting the foregoing, the Company and the Executive agree
that the Executive's failure to serve as the sole chief executive officer of
the Company or the delegation of the authority, duties or responsibilities of
the chief executive officer to another person or persons, including any
committee, shall be deemed to be an action by the Company which results in a
material diminution in the Executive's position, authority, duties, or
responsibilities as contemplated by Section 2(a));

                          (ii)    any termination or material reduction of a
material benefit under any Investment Plan or Welfare Plan in which the
Executive participates unless (A) there is substituted a comparable benefit
that is economically substantially equivalent to the terminated or reduced
benefit prior to such termination or reduction or (B) benefits under such
Investment Plan or Welfare Plan are terminated or reduced with respect to all
employees previously granted benefits thereunder;

                          (iii)   any failure by the Company to comply with any
of the provisions of Section 2(b), other than an isolated, insubstantial and
inadvertent failure not occurring in bad faith and which is remedied by the
Company promptly after receipt of notice thereof given by the Executive;

                          (iv)    any failure by the Company to comply with and
satisfy Section 8(c), provided that such successor has received at least ten
days prior written notice from the Company or the Executive of the requirements
of Section 8(c);




                                      4
<PAGE>   105
                          (v)     prior to the termination of the Executive for
Cause, the Executive's ceasing to be a director of the Company for any reason
other than his death, Disability (as hereinafter defined) or voluntary
resignation;

                          (vi)    the relocation or transfer of the senior
management's  executive offices to a location more than 15 miles from the
Executive's current principal residence set forth in Section 11(b) hereof; or

                          (vii)   without limiting the generality of the
foregoing, any material breach by the Company or any of its subsidiaries or
other affiliates (as defined below) of (A) this Agreement or (B) any other
agreement between the Executive and the Company or any such subsidiary or other
affiliate.

         As used in this Agreement, "affiliate" means, with respect to a
person, any other person controlling, controlled by or under common control
with the first person; the term "control," and correlative terms, means the
power, whether by contract, equity ownership or otherwise, to direct the
policies or management of a person; and "person" means an individual,
partnership, corporation, limited liability company, trust or unincorporated
organization, or a government or agency or political subdivision thereof.

                 (d)      Notice of Termination.  Any termination by the
Company for Cause or without Cause, or by the Executive for Good Reason or
without Good Reason, shall be communicated by Notice of Termination to the
other party hereto given in accordance with Section 11(b).  For purposes of
this Agreement, a "Notice of Termination" means a written notice which (i)
indicates the specific termination provision in this Agreement relied upon,
(ii) to the extent applicable, sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated and (iii) if the Date of
Termination (as defined below) is other than the date of receipt of such
notice, specifies the termination date (which date shall not be more than 15
days after the giving of such notice).  The failure by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance
which contributes to a showing of Good Reason or Cause shall not waive any
right of the Executive or the Company hereunder or preclude the Executive or
the Company from asserting such fact or circumstances in enforcing the
Executive's or the Company's rights hereunder.

                 (e)      Date of Termination.  "Date of Termination" means (i)
if the Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason or without Good Reason, the date of receipt of the
Notice of Termination or any later date specified therein, as the case may be,
(ii) if the Executive's employment is terminated by the Company other than for
Cause, the date on which the Company notifies the Executive of such termination
and (iii) if the Executive's employment is terminated by reason of death or
Disability, the date of death of the Executive or the Disability Effective
Date, as the case may be.

         4.      Obligations of the Company upon Termination.

                 (a)      Good Reason; Other Than for Cause, Death or
Disability.  If, during the Employment Period, the Company shall terminate the
Executive's employment other than for either Cause or Disability or the
Executive shall terminate his employment for Good Reason, and the termination
of the Executive's employment in any case is not due to his death:

                          (i)     the Company shall pay to the Executive in a
lump sum in cash within ten days after the Date of Termination the aggregate of
the following amounts:  (A) the sum of the Executive's Annual Base Salary
through the Date of Termination to the extent not theretofore paid and any
compensation previously deferred by the Executive (together with any accrued
interest or earnings thereon) and any accrued vacation pay ("Accrued
Obligations"); (B) an amount equal to the product of (x) the sum of (1) the
Executive's Annual Base Salary at the Date of Termination plus (2), if the Date
of Termination occurs prior to date that Bonuses have first been awarded after
the Effective Date, then the Executive's budgeted Bonus for the year in which
the Date of Termination occurs or, if the Date of Termination occurs after the
date that Bonuses have first been awarded after the Effective Date, then the
Executive's actual Bonus for the prior year multiplied by (y) a fraction, the
numerator of which is the number of full or partial months in the period from
the Date of Termination to the end of the Employment Period and the denominator
of which is 12; and (C) any amount arising from Executive's participation in,
or benefits under, any Investment Plans ("Accrued Investments"), which amounts
shall be payable in accordance with the terms and conditions of such Investment
Plans;

                          (ii)    for the remainder of the Employment Period,
or such longer period as any plan, program, practice or policy may provide, the
Company shall continue benefits provided under Welfare Plans to the Executive
and/or the Executive's family at least equal to those which would have been
provided to them if the Executive's employment had not been terminated or pay
the Executive monthly an amount of cash equal to the value of benefits under
Welfare Plans; provided, however, that if the Executive becomes reemployed with
another employer and is eligible to receive similar benefits under another
employer provided plan, such benefits or cash described herein shall be
secondary to and not duplicate those provided under such other plan during such
applicable period of eligibility (such continuation of such benefits or cash
for the applicable period hereinabove set forth in this clause (ii) shall be
hereinafter referred to as "Welfare Benefit Continuation").  For purposes of
determining eligibility of the Executive for retiree benefits pursuant to such
plans, practices, programs and policies, the Executive shall be considered to
have remained employed until the end of the Employment Period and to have
retired on the last day of such period;

                          (iii)   for the remainder of the Employment Period,
to the extent not theretofore paid or provided, the Company shall timely pay or
provide to the Executive and/or the Executive's family any other amounts or
benefits required to be paid or provided or which the Executive and/or the
Executive's family is eligible to receive pursuant to this Agreement and under




                                      6
<PAGE>   107
any plan, program, policy or practice or contract or agreement of the Company
("Other Benefits"); and

                          (iv)    notwithstanding the terms or conditions of
any stock option, stock appreciation right or similar agreements between the
Company and the Executive, the Executive shall vest, as of the Date of
Termination, in all rights under such agreements (i.e., stock options that
would otherwise vest after the Date of Termination) and thereafter shall be
permitted to exercise any and all such rights until the first anniversary of
the Date of Termination.

                 (b)      Death.  If the Executive's employment is terminated
by reason of the Executive's death during the Employment Period, the Company
shall pay to his legal representatives in a lump sum in cash within ten days
after the Date of Termination the aggregate of the following amounts: (i) the
Accrued Obligations; and (ii) the Accrued Investments.  The Company shall have
no further payment obligations to the Executive or his legal representatives
under this Agreement, other than for payment of Other Benefits and the timely
provision of the Welfare Benefit Continuation to the Executive's family.

                 (c)      Disability.  If the Executive's employment is
terminated by reason of the Executive's Disability during the Employment
Period, the Company shall have no further payment obligations to the Executive
or his legal representatives under this Agreement, other than for (i) payment
of Accrued Obligations, Accrued Investments and Other Benefits and (ii) the
timely provision of the Welfare Benefit Continuation to the Executive and his
family; provided however, that if the Executive is covered by a
Company-provided group or individual disability insurance policy at the date
the Executive's employment is terminated by reason of the Executive's
Disability and benefits under such policy are not then payable to the Executive
pursuant to the terms of such policy, then the Company shall continue to pay
the Executive his Annual Base Salary in effect at the date of such termination
(in accordance with the customary payroll practices of the Company) until the
first to occur of six months after such termination date or benefits becoming
payable to the Executive under such policy.

                 (d)      Cause; Other than for Good Reason.  If the
Executive's employment shall be terminated by the Company for Cause or by the
Executive without Good Reason during the Employment Period, the Company shall
have no further payment obligations to the Executive other than for payment of
Accrued Obligations, Accrued Investments and Other Benefits to the Date of
Termination.

         5.      Full Settlement.  The Company's obligation to make the
payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action which the Company may have
against the Executive or others; provided, however, that the Company may reduce
any payments it is required to make to the Executive under Section 4 by the
amount of the principal and accrued






                                      7
<PAGE>   108
interest on any loans or advances made to the Executive by the Company that are
outstanding on the Date of Termination (and such reduction in payments shall be
deemed to be payment in full by the Executive of such loans or advances to the
extent of such reduction).  In no event shall the Executive be obligated to
seek other employment or take any other action by way of mitigation of the
amounts payable to the Executive under any of the provisions of this Agreement
and, except as provided in Section 4(a)(ii), such amounts shall not be reduced
whether or not the Executive obtains other employment.  Neither the Executive
nor the Company shall be liable to the other party for any damages in addition
to the amounts payable under Section 4 hereof arising out of the termination of
the Executive's employment prior to the end of the Employment Period; provided,
however, that the Company shall be entitled to seek damages for any breach of
Sections 6 or 9 or criminal misconduct.

         6.      Confidential Information.

                 (a)      The Executive acknowledges that the Company and its
affiliates have trade, business and financial secrets and other confidential
and proprietary information (collectively, the "Confidential Information").  As
defined herein, Confidential Information shall not include (i) information that
is generally known to other persons or entities who can obtain economic value
from its disclosure or use and (ii) information required to be disclosed by the
Executive pursuant to a subpoena or court order, or pursuant to a requirement
of a governmental agency or law of the United States of America or a state
thereof or any governmental or political subdivision thereof; provided,
however, that the Executive shall take all reasonable steps to prohibit
disclosure pursuant to subsection (ii) above.

                 (b)      The Executive agrees (i) to hold such Confidential
Information in confidence and (ii) not to release such information to any
person (other than Company employees and other persons to whom the Company has
authorized the Executive to disclose such information and then only to the
extent that such Company employees and other persons authorized by the Company
have a need for such knowledge).

                 (c)      The Executive further agrees not to use any
Confidential Information for the benefit of any person or entity other than the
Company.

                 (d)      The Executive's obligations under this Section 6
shall terminate (i) on the first anniversary of the Date of Termination if the
Executive's employment is terminated by the Company for Cause or due to
Disability or by the Executive without Good Reason or (ii) at the end of the
Employment Period if (A) the Executive's employment is terminated by the
Company without Cause (and not due to Disability) or by the Executive for Good
Reason and (B) the Company makes the payments and performs its obligations
required under Section 4 throughout the Employment Period.

<PAGE>   109
         7.      Surrender of Materials Upon Termination.  Upon any termination
of the Executive's employment, the Executive shall immediately return to the
Company all copies, in whatever form, of any and all Confidential Information
and other properties of the Company and its affiliates which are in the
Executive's possession, custody or control.

         8.      Successors.

                 (a)      This Agreement is personal to the Executive and
without the prior written consent of the Company shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution.  This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.

                 (b)      This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns.

                 (c)      The Company will require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the
same extent that the Company would be required to perform it if no such
succession had taken place.  As used in this Agreement, "Company" shall mean
the Company as hereinbefore defined and any successor to its business and/or
assets as aforesaid which assumes and agrees to perform this Agreement by
operation of law, or otherwise.

         9.      Non-Competition.

                 (a)      The term of Non-Competition (herein so called) shall
be for a term beginning on the date hereof and continuing until (i) the first
anniversary of the Date of Termination if the Executive's employment is
terminated by the Company for Cause or due to Disability or by the Executive
without Good Reason or (ii) the end of the Employment Period if (A) the
Executive's employment is terminated by the Company without Cause (and not due
to Disability) or by the Executive for Good Reason and (B) the Company makes
the payments and performs its obligations required under Section 4 throughout
the Employment Period.

                 (b)      During the term of Non-Competition, the Executive
will not (other than for the benefit of the Company pursuant to this Agreement)
directly or indirectly, individually or as an officer, director, employee,
shareholder, consultant, contractor, partner, joint venturer, agent, equity
owner or in any capacity whatsoever, (i) engage in any Spanish language radio
or television broadcasting business that transmits a primary or city-grade
signal within a Metro Survey Area (as currently defined by The Arbitron Company
in its Radio Markets Reports) in which a station directly operated by the
Company transmits a primary or city-grade signal (A), with respect to the term
of Non- Competition that is during the Executive's employment, during such term
of employment, and





                                      9
<PAGE>   110
(B), with respect to the term of Non-Competition that is after the term of the
Executive's employment, on the Date of Termination (all such areas being
collectively called the "Geographic Area") (a "Competing Business"), (ii) hire,
attempt to hire, or contact or solicit with respect to hiring any employee of
the Company, or (iii) divert or take away any customers or suppliers of the
Company in the Geographic Area.  Notwithstanding the foregoing, the Company
agrees that the Executive may own less than five percent of the outstanding
voting securities of any publicly traded company that is a Competing Business
so long as the Executive does not otherwise participate in such competing
business in any way prohibited by the preceding clause.  As used in this
Section 9(b), "Company" shall include the Company and any of its subsidiaries.

                 (c)      During the term of Non-Competition, the Executive
will not use the Executive's access to, knowledge of, or application of
Confidential Information to perform any duty for any Competing Business; it
being understood and agreed to that this paragraph 9(c) shall be in addition to
and not be construed as a limitation upon the covenants in paragraph 9(b)
hereof.

                 (d)      The Executive acknowledges that the geographic
boundaries, scope of prohibited activities, and time duration of the preceding
paragraphs are reasonable in nature and are no broader than are necessary to
maintain the confidentiality and the goodwill of the Company's proprietary
information, plans and services and to protect the other legitimate business
interests of the Company.

         10.     Effect of Agreement on Other Benefits.  The existence of this
Agreement shall not prohibit or restrict the Executive's entitlement to full
participation in the executive compensation, employee benefit and other plans
or programs in which executives of the Company are eligible to participate.

         11.     Miscellaneous.

                 (a)      This Agreement shall be governed by and construed in
accordance with the laws of the State of Texas, without reference to principles
of conflict of laws.  The captions of this Agreement are not part of the
provisions hereof and shall have no force or effect.  This Agreement may not be
amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

writing in accordance herewith.  Notice and communications shall be effective
when actually received by the addressee.

                 (c)      If any provision of this Agreement is held to be
illegal, invalid or unenforceable under present or future laws effective during
the term of this Agreement, such provision shall be fully severable; this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a portion of this Agreement; and
the remaining provisions of this Agreement shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance from this Agreement.  Furthermore, in lieu of
such illegal, invalid or unenforceable provision there shall be added
automatically as part of this Agreement a provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible and be legal,
valid and enforceable.

                 (d)      The Company agrees to attempt to obtain and maintain
a director's and officer's liability insurance policy during the term of the
Executive's employment covering the Executive on commercially reasonable terms,
and the amount of coverage shall be reasonable in relation to the Executive's
position and responsibilities hereunder; provided, however, that such coverage
may be reduced or eliminated to the extent that the Company reduces or
eliminates coverage for its directors and executives generally.

                 (e)      The Company may withhold from any amounts payable
under this Agreement such Federal, state or local taxes as shall be required to
be withheld pursuant to any applicable law or regulation.

                 (f)      The Executive's or the Company's failure to insist
upon strict compliance with any provision of this Agreement or the failure to
assert any right the Executive or the Company may have hereunder, including,
without limitation, the right of the Executive to terminate employment for Good
Reason, shall not be deemed to be a waiver of such provision or right or any
other provision or right of this Agreement.

                 (g)      The Executive acknowledges that money damages would
be both incalculable and an insufficient remedy for a breach of Section 6 or 9
by the Executive and that any such breach would cause the Company irreparable

         bond or other security, to equitable relief, including injunctive
         relief and specific performance, in connection with a breach of

                 (h)      The provisions of this Agreement constitute the
complete understanding and agreement between the parties with respect to the
subject matter hereof.

                 (i)      This Agreement may be executed in two or more
counterparts.

                 (j)      In the event any dispute or controversy arises under
this Agreement and is not resolved by mutual written agreement between the
Executive and the Company within 30 days after notice of the dispute is first
given, then, upon the written request of the Executive or the Company, such
dispute or controversy shall be submitted to arbitration to be conducted in
accordance with the rules of the American Arbitration Association.  Judgment
may be entered thereon and the results of the arbitration will be binding and
conclusive on the parties hereto.  Any arbitrator's award or finding or any
judgment or verdict thereon will be final and unappealable.  All parties agree
that venue for arbitration will be in Dallas, Texas, and that any arbitration
commenced in any other venue will be transferred to Dallas, Texas, upon the
written request of any party to this Agreement.  All arbitrations will have
three individuals acting as arbitrators:  one arbitrator will be selected by
the Executive, one arbitrator will be selected by the Company, and the two
arbitrators so selected will select a third arbitrator.  Any arbitrator
selected by a party will not be affiliated, associated or related to the party
selecting that arbitrator in any matter whatsoever.  The decision of the
majority of the arbitrators will be binding on all parties.  The Company shall
be responsible for paying its own and the Executive's attorneys fees, costs and
other expenses pertaining to any such arbitration and enforcement regardless of
whether an arbitrator's award or finding or any judgment or verdict thereon is
entered against the Executive.  The Company shall promptly (and in no event
after ten days following its receipt from the Executive of each written request
therefor) reimburse the Executive for his reasonable attorneys fees, costs and
other expenses pertaining to any such arbitration and the enforcement thereof.

         IN WITNESS WHEREOF, the Executive has hereunto set the Executive's
hand and, pursuant to the authorization from the Board, the Company has caused
this Agreement to be executed in its name on its behalf, all as of the day and
year first above written.

(an "ACCEPTANCE NOTICE") within 30 days following delivery of the Offer Notice
(provided that if such offer relates to a proposed Transfer of Common Stock
representing more than 10% of the Common Stock owned by such Offering
Stockholder on the date hereof and more than two percent of the then
outstanding Common Stock such Non- Offering Stockholder shall have 60 days in
which to deliver such Acceptance Notice (either such period being referred to
herein as the "ROFO ACCEPTANCE PERIOD")), stating that such Non-Offering
Stockholder is willing to purchase all of the Offered Shares for the Offer
Price and on the other terms set forth in the Offer Notice, the Offering
Stockholder will sell all (but not less than all) of the Offered Shares to such
Non-Offering Stockholder, and such Non-Offering Stockholder will purchase such
Offered Shares from the Offering Stockholder, on the proposed terms and subject
to the conditions set forth below.  In such case, the Tichenor Stockholders
only, with the Offered Shares allocated (unless otherwise agreed by the
Tichenor Stockholders requesting to purchase Offered Shares) based on the
number of Offered Shares requested to be purchased by each of the Tichenor
Stockholders, will be the "PURCHASING STOCKHOLDER" with respect to a proposed
Third-Party Sale by any Clear Channel Stockholder, and the Clear Channel
Stockholders only, with the Offered Shares allocated (unless otherwise agreed
by the Clear Channel Stockholders requesting to purchase Offered Shares) based
on the number of Shares owned by each of the Clear Channel Stockholders who
request to purchase Offered Shares (but in no event so as to require any
Stockholder to purchase in excess of the number of Offered Shares requested by
such Stockholder), will be the Purchasing Stockholder with respect to a
proposed Third-Party Sale by any Tichenor Stockholder.

                 (c)      The ROFO Closing.  The consummation of any purchase
of the Offered Shares by the Purchasing Stockholder pursuant to this Section
2.3 (the "ROFO CLOSING") will occur no more than five Business Days following
the delivery of the Acceptance Notice (such five Business Day period being
referred to herein as the "ROFO CLOSING PERIOD") at such time and place as may
be agreed upon by the Offering Stockholder and the Purchasing Stockholder or,
if such parties fail to agree to such time and place, at the principal
executive offices of the Company at 10:00 a.m. (Central Time) on the fifth
Business Day following the expiration of the ROFO Acceptance Period.  At the
ROFO Closing, (i) the Purchasing Stockholder will deliver to the Offering
Stockholder by certified or official bank check or wire transfer to an account
designated by the Offering Stockholder an amount in immediately available funds
equal to the Offer Price, (ii) the Offering Stockholder will deliver one or
more certificates evidencing the Offered Shares, together with such other duly
executed instruments or documents (executed by the Offering Stockholder) as may
be reasonably requested by the Purchasing Stockholder to acquire the Offered





                                      -7-

Shares free and clear of any and all claims, liens, pledges, charges,
encumbrances, security interests, options, trusts, commitments and other
restrictions of any kind whatsoever (collectively, "ENCUMBRANCES"), except for
Encumbrances created by this Agreement, federal or state securities law or the
Purchasing Stockholder or as specified in the Offer Notice, and (iii) the
Offering Stockholder will be deemed to represent and warrant to the Purchasing
Stockholder that, upon the ROFO Closing, the Offering Stockholder will convey
and the Purchasing Stockholder will acquire the entire record and beneficial
ownership of, and good and valid title to, the Offered Shares, free and clear
of any and all Encumbrances, except for Encumbrances created by this Agreement,
federal and state securities laws or the Purchasing Stockholder or as described
in the Offer Notice.

                 (d)      Right to Consummate Third-Party Sale.  Subject to the
provisions of Section 2.4 below, if no Acceptance Notice relating to the
proposed Third-Party Sale is delivered to the Offering Stockholder prior to the
expiration of the ROFO Acceptance Period, or an Acceptance Notice is so
delivered to the Offering Stockholder but the ROFO Closing fails to occur prior
to the expiration of the ROFO Closing Period (unless the Purchasing Stockholder
was ready, willing and able prior to the expiration of the ROFO Closing Period
to consummate the transactions to be consummated by the Purchasing Stockholder
at the ROFO Closing), the Offering Stockholder may (without affecting its
rights, if any, arising out of such failure) consummate the Third-Party Sale,
but only (i) during the 180 calendar day period immediately following the
expiration of the ROFO Acceptance Period (in the event that no Acceptance
Notice was timely delivered to the Offering Stockholder) or the 180 calendar
day period immediately following the expiration of the ROFO Closing Period (in
the event that an Acceptance Notice was timely delivered to the Offering
Stockholder but the ROFO Closing failed timely to occur), (ii) at a price at
least equal to 95% of the Offer Price, and (iii) upon other terms not
materially less favorable to the Offering Stockholder than those set forth in
the Offer Notice.

         2.4     Participation Offer.      Prior to consummating any
Third-Party Sale and after complying with the provisions of Section 2.3 above,
the Stockholder proposing to complete such Third-Party Sale (the "TRANSFEROR")
shall offer (the "PARTICIPATION OFFER") to include in the proposed Third-Party
Sale a number of shares of Stock (regardless of whether such shares are of the
same class being sold by the Transferor) designated by any of the other
Stockholders, not to exceed, in respect of any such other Stockholder, the
number of shares equal to the product of (a) the aggregate number of shares to
be sold by the Transferor to the proposed transferee and (b) a fraction with a
numerator equal to the number of shares of Fully-Diluted Common Stock held by
such other Stockholder and a denominator equal to the number of shares of
Fully-Diluted Common Stock held by all Stockholders; provided that if the
consideration to be received by the Transferor includes any securities, only
Stockholders who are Accredited Investors shall be entitled to include their
shares in such sale (but in such a case, each Stockholder shall be entitled to
include in such sale a number of its shares, without duplication, equal to the
total number of shares held by its Affiliates which are excluded from such sale
by the operation of this proviso).  The Transferor shall give written notice to
each other non-transferring Stockholder of the Participation Offer (the
"TRANSFEROR'S NOTICE") at least 20 days prior to the proposed Third-Party Sale.
The Transferor's Notice shall specify (a) the Offer Price for which the
Transferor proposes in good faith to sell the shares to be offered in such
Third-Party Sale (the "SALE SHARES"), (b) the identity of the purchaser in such
Third-Party Sale (if then known), (c) the place and date on which the Third
- -Party Sale is to be consummated and (d) all





                                      -8-
<PAGE>   122
other material terms of the proposed Third-Party Sale.  Each Stockholder who
wishes to include shares of Common Stock in the proposed Third-Party Sale in
accordance with the terms of this Section 2.4 shall so notify the Transferor
not more than 10 days after the date of the Transferor's Notice.  The
Participation Offer shall be conditioned upon the Transferor's sale of Common
Stock pursuant to the transactions contemplated in the Transferor's Notice with
the transferee named therein.  If any other Stockholder or other Stockholders
have accepted the Participation Offer, the Transferor shall reduce to the
extent necessary the number of shares of Common Stock it otherwise would have
sold in the proposed sale so as to permit other Stockholders who have accepted
the Participation Offer to sell the number of shares that they are entitled to
sell under this Section 2.4, and the Transferor and such other Stockholder or
other Stockholders shall sell the number of shares of Common Stock specified in
the Participation Offer to the proposed transferee in accordance with the terms
of such sale set forth in the Transferor's Notice.

         2.5     Conversion of Class B Common Stock.  Neither a conversion of
shares of Class B Common Stock held by the Clear Channel Stockholders into
Class A Common Stock, nor a conversion of Class A Common Stock held by the
Clear Channel Stockholders into Class B Common Stock shall be deemed a Transfer
if the shares of Class A Common Stock or Class B Common Stock, as the case may
be, issuable upon such conversion are held by a Clear Channel Stockholder.
After the Conversion Date the obligations of each of the Stockholders to make a
Participation Offer pursuant to Section 2.4 shall terminate and be of no
further force or effect.  In addition, after the Conversion Date the ROFO
Acceptance Period with respect to any Third-Party Sales shall be reduced to ten
days regardless of the number of shares of Common Stock that are the subject of
the Offer Notice.

         2.6     Transfers Subject to Compliance with Securities Act.  No
shares of Common Stock may be transferred by a Stockholder (other than pursuant
to an effective registration statement under the Securities Act) unless such
Stockholder first delivers to the Company an opinion of counsel, which opinion
and counsel shall be reasonably satisfactory to the Company, to the effect that
such transfer in not required to be registered under the Securities Act.

         2.7     Transfers in Violation Void.  Any purported Transfer by a
Stockholder which is not permitted by the provisions of this Article II, or
which is in violation of such provisions, shall be void and of no force and
effect whatsoever.

         2.8     Treatment of Clear Channel Option.  The Clear Channel Option
and the transferability thereof shall be subject to the provisions of this
Agreement for all purposes as if CCC owned the shares subject thereto and as if
any transfer of the Clear Channel Option were a transfer of the underlying
shares of Class B Common Stock and the shares underlying Clear Channel Option
shall be deemed outstanding for the purposes of this Agreement.

                                  TERMINATION

         The provisions of this Agreement shall terminate in respect of all
Stockholders (a) upon the written consent of (i) Stockholders who then hold
Common Stock representing at least seventy-five percent of the Fully-Diluted
Common Stock then held by all of the Stockholders (other than CCC  or its
Affiliates, if CCC or one of its Affiliates then holds 25% or more of the
outstanding Common Stock) and (ii) CCC, if CCC or any of its Affiliates then
holds 25% or more of the outstanding Common Stock, and (b) immediately prior to
the consummation of a merger, consolidation, share exchange or other similar
transaction in which the holders of a majority of the outstanding Common Stock
of the Company shall cease to hold a majority of the common equity interests in
the surviving entity.  A Person who ceases to hold any Stock and who ceases to
beneficially own any Stock shall cease to be a Stockholder and shall have no
further rights under this Agreement.

                                   ARTICLE IV

II of this Agreement restricting the Transfer of shares of Common Stock will

Stockholder.

                                                                    EXHIBIT 5.18


                           INDEMNIFICATION AGREEMENT


         This Agreement is made as of _________________, by and between Heftel
Broadcasting Corporation, a Delaware corporation (the "Company"), and the
undersigned, a director and/or officer of the Company ("Indemnitee"), with
respect to the following facts.

         A.      The Company is aware that competent and experienced persons
are increasingly reluctant to serve as directors or officers of corporations
unless they are protected by comprehensive liability insurance or
indemnification, due to increased exposure to litigation costs and risks
resulting from their service to such corporations, and due to the fact that the
exposure frequently bears no reasonable relationship to the compensation of
such directors and officers.

         B.      The following facts contribute to unfairness to directors and
officers:  (i) laws regarding the duties of directors and officers are often
ambiguous; (ii) costs of litigation may be so enormous (whether or not the case
is meritorious) that the defense and/or settlement of such litigation is often
beyond the personal resources of officers and directors; and (iii) delay in
litigation may extend the period of exposure to an officer or director until
after retirement or death, thus forcing spouses, heirs, executors or
administrators to expend funds.

         C.      The Company has been advised that there can be no assurance
that directors' and officers' liability insurance will be available to the
Company and Indemnitee in the future, and that the cost of such insurance, if
available, may not be acceptable to the Company.

         D.      Indemnitee questions the adequacy and reliability of the
protection presently afforded by the Delaware General Corporation Law, the
California General Corporation Law (together with the Delaware General
Corporation Law, the "Corporation Laws") and the Company's Certificate of
Incorporation and Bylaws, in part because certain of the indemnification
provisions of the Corporation Laws are for the most part merely permissive and
because the impact of provisions of the Company's Certificate of Incorporation
and Bylaws is presently uncertain.  In addition, the Company may be subject to
the provisions of certain other states' laws under statutes relating to
"nominally foreign" or "pseudo-foreign" corporations.

         E.      Indemnitee currently serves as a director and/or officer of
the Company.  Indemnitee is concerned about continuing to serve the Company as
a director and/or officer without assurance that indemnities available to him
are, and will be, adequate to protect him against the risks associated with his
service to the Company.

         F.      The Company, in order to induce Indemnitee to continue to
serve the Company as a director and/or officer without assurance that
indemnities available to him are, and will be, adequate to protect him against
the risk associated with his service to the Company, has agreed to provide
Indemnitee with the benefits contemplated by this Agreement, which benefits are
intended to provide Indemnitee with the maximum possible protection permitted
by law.

         G.      As a result of the provision of such benefits and in reliance
thereon Indemnitee is continuing to serve as a director or officer.
<PAGE>   130
         NOW, THEREFORE, in consideration of the foregoing and the promises,
conditions, representations and warranties set forth herein, the Company and
Indemnitee hereby agree as follows:

         1.      Definitions.  The following terms, as used herein, shall have
the following respective meanings:

                 1.1      "Covered Act" means (i) any actual or alleged action
taken or attempted by Indemnitee (including, without limitation, any breach of
duty, neglect, error, misstatement, or misleading statement) (a) in his
capacity as, or otherwise by reason of, or arising out of his being, a
director, officer, employee or other agent of the Company, or (b) by reason of
the fact he is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise; or (ii) any inaction or omission on Indemnitee's
part while acting in any of the foregoing capacities.  For purposes solely of
this Agreement, it shall be conclusively deemed between the parties that the
Indemnitee is serving at the request of the Company whenever such director
serves as an officer, director, employee or other agent of any business entity
controlling, controlled by or under common control with the Company.

                 1.2      "D & O Insurance" means directors' and officers'
liability insurance with coverage sufficient to ensure performance of the
indemnification obligation of the Company hereunder issued by one or more
reputable insurers.

                 1.3      "Excluded Claim" means any payment for Losses or
Expenses in connection with any claim: (i) for the return by Indemnitee of any
remuneration which is illegal; or (ii) for an accounting of profits in fact
made from the purchase or sale by Indemnitee of securities of the Company
within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as
amended, or similar provisions of any state law, if the Company is in fact
entitled to recover such profits; or (iii) resulting from Indemnitee's
knowingly fraudulent, deliberately dishonest or intentional misconduct; or (iv)
the payment of which by the Company under this Agreement is not permitted by
applicable law; or (v) initiated or brought voluntarily by Indemnitee and not
by way of defense, except with respect to proceedings brought to establish or
enforce a right to indemnification or advancement of Expenses and Losses or a
proceeding initiated with the approval of a majority of the members of the
Board of Directors.

                 Any facts pertaining to any other director, officer, employee
or agent of the Company shall not be imputed to Indemnitee for the purpose of
determining an Excluded Claim.

                 1.4      "Expenses" means any reasonable expenses incurred by
Indemnitee as a result of a claim or claims whether brought by or in the right
of the Company (e.g., derivatively by stockholders of the Company for the
benefit of the Company) or otherwise and whether of a civil, criminal,
administrative or investigative nature made against him for, or otherwise in
respect of, Covered Acts including, without limitation, counsel fees, costs of
bonds, and other costs of proceedings or appeals.





                                       2
<PAGE>   131
                 1.5      "Loss" means any amount which Indemnitee pays or is
obligated to pay as a result of a claim or claims whether brought by or in the
right of the Company (e.g., derivatively by stockholders of the Company for the
benefit of the Company) or otherwise and whether of a civil, criminal,
administrative or investigative nature made against him or for or otherwise in
respect of Covered Acts including, without limitation, damages, judgments, sums
paid in settlement of such claim or claims, sums paid in respect of any
deductible under any policy of D & O Insurance, and fines and penalties other
than fines and penalties for which indemnification is not permitted by
applicable law.

         2.      Maintenance of D & O Insurance.

                 2.1      The Company hereby covenants and agrees that, as long
as Indemnitee shall continue to serve as a director or officer of the Company
and thereafter so long as Indemnitee shall be subject to any possible claim or
threatened, pending or completed action, suit or proceeding, whether civil,
criminal or investigative, by reason of his services to the Company, the
Company, subject to Section 2.3 hereof, shall obtain and maintain in full force
and effect D & O Insurance.

                 2.2      All policies of D & O Insurance shall be written in
such a manner as to provide Indemnitee the same rights and benefits, subject to
the same limitations, as are accorded to the Company's directors or officers
most favorably insured by such policy.

                 2.3      The Company shall have no obligation to maintain D &
O Insurance if the Board of Directors of the Company determines in good faith
that such insurance is not reasonably available, the premium costs for such
insurance are disproportionate to the amount of coverage provided, or the
coverage provided for such insurance is limited by exclusions so as to provide
an insufficient benefit.

         3.      Indemnification

                 3.1      The Company, at the request of Indemnitee, shall
indemnify Indemnitee and hold him harmless from any and all Losses and Expenses
subject, in each case, to the further provisions of this Agreement.

                 3.2      The protection afforded to Indemnitee hereunder is
intended to supplement the other protections to which Indemnitee may be
entitled now or hereafter under statutory law, the Company's Certificate of
Incorporation or Bylaws, the D & O Insurance, vote of stockholders or of
directors or otherwise, and all of such protections and the provisions hereof
are intended to be cumulative.

                 3.3      Indemnitee may seek such indemnification under
statutory law, the Company's Certificate of Incorporation or Bylaws, the D & O
Insurance, the provisions of Section 3.1 of this Agreement, or otherwise
concurrently or in such sequence as Indemnitee may choose, in his sole
discretion.





                                       3
<PAGE>   132
                 3.4      The Company shall have no obligation to indemnify
Indemnitee for and hold him harmless from any Loss or Expense which constitutes
an Excluded Claim.

         4.      Indemnification Procedures.

                 4.1      Promptly after receipt by Indemnitee of notice of the
commencement of or of the threat of commencement of any action, suit or
proceeding, Indemnitee shall notify the Company of the commencement or threat
thereof; but the omission so to notify or delay in notifying the Company will
not relieve it from any liability which it may have to Indemnitee except to the
extent that the Company is actually prejudiced by any such omission or delay.

                 4.2      The Company shall give prompt notice of the
commencement of such action, suit or pending to the insurers on the D & O
Insurance, if any, in accordance with the procedures set forth in the
respective policies in favor of Indemnitee.  The Company shall thereafter take
all necessary or desirable action to cause such insurers to pay, on behalf of
Indemnitee, all amounts as a result of such action, suit or proceeding in
accordance with the terms of such policies.

                 4.3      If such action, suit or proceeding is other than by
or in the right of the Company, Indemnitee shall, assuming that the D & O
Insurance, if any, then provides for Indemnitee's defense, accept the defense
provided under the D & O Insurance.  If it does not so provide for his defense,
or if Indemnitee determines that the insurers under the D & O Insurance are
unable or unwilling to defend, contest and protect Indemnitee adequately
against any such action, suit or proceeding, or if no D & O Insurance is
maintained pursuant to Section 2.3 hereof, Indemnitee may at his option, either
control the defense thereof himself or require the Company to defend him;
provided, however, that Indemnitee may not control the defense himself or
require the Company to defend him if such decision would jeopardize the
coverage provided by the D & O Insurance, if any, to the Company and/or the
other directors and officers covered thereby.  If (a) Indemnitee require the
Company to defend him, (b) the Company does not maintain any D & O Insurance
pursuant to Section 2.3 hereof or (c) Indemnitee proceeds under the D & O
Insurance but Indemnitee determines that the insurers under the D & O Insurance
are unable or unwilling to defend, contest and protect Indemnitee adequately
against any such action, suit or proceeding, then the Company shall promptly
undertake to defend any such action, suit or proceeding, at the Company's sole
cost and expense, utilizing counsel of the Indemnitee's choice who has been
approved by the Company.  If appropriate the Company shall have the right to
participate in the defense of such action, suit or proceeding.

                 4.4      If such action, suit or proceeding is by or in the
right of the Company, Indemnitee may, at his option, either control the defense
thereof himself or accept the defense provided under the D & O Insurance, if
any; provided, however, that Indemnitee may not control the defense himself if
such decision would jeopardize the coverage provided by the D & O Insurance, if
any, to the Company and/or the other directors and officers covered thereby.

<PAGE>   133
                 4.5      If the Company shall fail to defend, contest or
otherwise protect Indemnitee in a timely manner against any such action, suit
or proceeding which is not by or in the right of the Company, Indemnitee shall
have the right to do so, including without limitation, the right to make any
compromise or settlement thereof, and to recover from the Company all
attorney's fees, reimbursements and all amounts paid as a result thereof.

                 4.6      Expenses and Losses incurred or to be incurred by
Indemnitee from time to time as a result of any actions, suit or proceeding
covered by the indemnity provisions of this Agreement (including, without
limitation, an action, suit or proceeding by or in the right of the Company)
which have not been paid by the insurers under the D & O Insurance, if any,
shall be paid by the Company within 30 days of the written request of the
Indemnitee, whether or not the Company believes that such Expenses and Losses
may constitute an Excluded Claim.  At the election of Indemnitee, Indemnitee
may from time to time request the Company to advance to his funds to pay any
expenses which would be subject to reimbursement hereunder.  The Company shall
provide such advances within five business days after written request thereof.
Indemnitee agrees that he will reimburse the Company for all Losses and
Expenses paid or advanced by the Company in connection with any such action,
suit or proceeding against Indemnitee in the event, and only to the extent,
that a determination shall have been made by an arbitrator that Indemnitee is
not entitled to be indemnified by the Company for such Losses and Expenses
because the claim is an Excluded Claim.

         5.      Settlement.  Except as otherwise provided in Section 4.5,
hereof, Indemnitee shall not settle any suit, action or proceeding without the
Company's prior written consent.  The Company shall not settle any suit, action
or proceeding in any manner which would impose any obligation on Indemnitee
which is not covered by indemnification hereunder without Indemnitee's written
consent.  Neither the Company nor Indemnitee shall  unreasonably withhold their
consent to any proposed settlement.

         6.      Miscellaneous.

                 6.1      Notices.  Any communication contemplated under this
Agreement shall be in writing and shall be effective upon personal delivery or
five days after deposit in the United States mail, postage prepaid, certified
or registered, return receipt requested, addressed as follows or to such other
address as may be specified in the same manner:

                 If to Indemnitee:      To the address set forth on the
                                        signature page hereof.

                 6.2      Enforcement.

                          (a)     The burden of proving that indemnification is
not appropriate shall be on the Company and any actual determination by the
Company (including any determination made by its Board of Directors or
stockholders, or by independent legal counsel) that Indemnitee is not entitled
to indemnification hereunder shall not be a defense to such action or create a
presumption that Indemnitee has not met the applicable standard for
indemnification.  If Indemnitee commences an action to enforce this Agreement,
the Company shall nevertheless be obligated, subject to Indemnitee's obligation
to reimburse the Company contained in Section 4.6 hereof, to pay Expenses and
Losses from time to time as incurred by Indemnitee.

                          (b)     If any action is instituted under this
Agreement, or to enforce or interpret any of the terms of this Agreement, all
court costs and expenses, including reasonable counsel fees, incurred or to be
incurred by Indemnitee with respect to such action or arbitration shall be paid
by the Company within 30 days of written request by the Indemnitee, unless and
until an arbitrator determines that each of the material assertions made by
Indemnitee as a basis for such action were not made in good faith or were
frivolous.

                          (c)     All agreements and obligations of the Company
contained herein shall continue during the period the Indemnitee is a director,
officer, employee or agent of the Company (or is serving at the request of the
Company as a director, officer, employee or agent of another corporation or
other enterprise) and shall continue thereafter so long as Indemnitee shall be
subject to any possible claim or threatened, pending or completed action, suit
or proceeding, whether civil, criminal or investigative, by reason of the fact
that Indemnitee was a director or officer of the Company or serving in any
other capacity referred to herein.

                          (d)     The Company's indemnity obligations hereunder
shall be applicable to any and all claims made after the date hereof regardless
of when the facts upon which such claims are based occurred, including times
prior to the date hereof.

                          (e)     The Company expressly confirms and agrees
that it has entered into this Agreement and assumed the obligations imposed on
the Company hereby, in order to induce Indemnitee to serve, or continue to
serve, as a director and/or officer of the Company, and acknowledges that
Indemnitee is relying upon this Agreement in agreeing to serve or in continuing
to serve in such capacity.

                 6.3      Provisions Not to Inure to Benefit of Insurers.  It
is the intention of the parties in entering into this Agreement that the
insurers under the D & O Insurance, if any, shall be obligated ultimately to
pay any claims by Indemnitee which are covered by the D & O Insurance, and
nothing herein shall be deemed to diminish or otherwise restrict the Company's
or Indemnitee's right to proceed or collect against any insurers under the D &
O Insurance or to give such insurers any rights against the Company under or
with respect to this Agreement,





                                       6
<PAGE>   135
including, without limitation, any right to be subrogated to Indemnitee's
rights hereunder, unless otherwise expressly agreed to by the Company in
writing and the obligation of such insurers to the Company and Indemnitee shall
not be deemed reduced or impaired in any respect by virtue of the provisions of
this Agreement.

                 6.4      Severability.  In the event that any provision of
this Agreement is determined by a court to require the Company to do or to fail
to do any act which is in violation of applicable law, such provision shall be
limited or modified in its application to the minimum extent necessary to avoid
a violation of law and, as so limited or modified, such provision and the
balance of this Agreement shall be enforceable in accordance with their terms.
Without limiting the generality of the foregoing, if this Agreement or any
portion thereof shall be invalidated on any ground, the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any
applicable portion of this Agreement that shall not have been invalidated.

                 6.5      Partial Indemnification.  If Indemnitee is entitled
under any provision of this Agreement to indemnification by the Company for
some or a portion of the Expenses and Losses but not, however, for the total
amount thereof, the Company shall nevertheless indemnify Indemnitee for the
portion of such Expenses and Losses to which Indemnitee is entitled to
indemnification.

                 6.6      Choice of Law.  The validity, construction,
performance, and enforcement of this Agreement, and each part thereof, shall be
governed by and construed in accordance with the laws of the State of Delaware,
applicable to agreements made and to be wholly performed in such state.

                 6.7      Successor and Assigns.  This Agreement shall be (i)
binding upon all successors and assigns of the Company (including any
transferee of all or substantially all of its assets and any successor by
merger or otherwise by operation of law) and (ii) shall be binding on and inure
to the benefit of the heirs, personal representatives and estate of Indemnitee.

                 6.8      Amendment.  No amendment, modification, termination
or cancellation of this Agreement shall be effective unless made in writing and
signed by each of the parties hereto.  This Agreement constitutes the entire
agreement between the parties hereto with respect to the subject matter hereof.

proposed filing to Clear Channel as soon as practicable (but in no event less
than 30 days before the anticipated effective date of such registration
statement), and such notice shall offer Clear Channel the opportunity to
register such number of Registrable Securities as Clear Channel may request (a
"Piggyback Registration").  Subject to Section 3(b), the Company shall include
in each such Piggyback Registration all Registrable Securities requested to be
included in the registration for such offering by Clear Channel.  Clear Channel
shall be permitted to withdraw all or part of its Piggyback Securities from a
Piggyback Registration at any time prior to the effective date thereof.

                 (b)      The Company shall use all commercially reasonable
efforts to cause the managing Underwriter or Underwriters of a proposed
underwritten offering to permit the Registrable Securities requested to be
included in the registration statement for such offering under Section 3(a)
(the "Piggyback Securities") to be included on the same terms and conditions as
any similar securities included therein.  Notwithstanding the foregoing, the
Company shall not be required to include Clear Channel's Piggyback Securities

agreement between the Company and the managing Underwriter or Underwriters and

subsequent to the exercise or termination of all demand registration rights
granted to the Tichenor Holders, the managing Underwriter or Underwriters of a
proposed underwritten offering advise the Company in writing that in their
opinion the total amount of securities, including Piggyback Securities and
other securities proposed to be registered by Other Holders pursuant to similar
piggyback registration rights, to be included in such offering is sufficiently
large to materially and adversely affect the price or success of the Offering
(a "Material Adverse Effect"), then in such event the securities to be included
in such offering shall be allocated first





                                      -4-
<PAGE>   141
to the party initiating the proposed underwritten offering; second, to the
extent that any additional securities can, in the opinion of such managing
Underwriter or Underwriters, be sold without any such Material Adverse Effect,
pro rata (based on the number of Registrable Securities and other securities
requested to be included in such registration by Clear Channel or any Other
Holder) among Clear Channel and the Other Holders registering securities of the
Company pursuant to similar piggyback registration rights; and third, to the
extent the Company is not the party initiating such proposed underwritten
offering and that any additional securities can, in the opinion of such
managing Underwriter or Underwriters, be sold without any Material Adverse
Effect, to the Company.  If, subsequent to the Conversion Date, but prior to
the exercise or termination of all demand registration rights granted to
Tichenor Holders, the managing Underwriter or Underwriters of a proposed
underwritten offering advise the Company in writing that in their opinion the
total amount of securities, including Piggyback Securities and other securities
proposed to be registered by Other Holders pursuant to similar piggyback
registration rights, to be included in such offering is sufficiently large to
cause a Material Adverse Effect, then in such event the securities to be
included in such offering shall be allocated first to the party initiating the
proposed underwritten offering; second, to the extent that any additional
securities can, in the opinion of such managing Underwriter or Underwriters, be
sold without any such Material Adverse Effect, (x) 50% of the total amount of
additional securities shall be allocated to the Tichenor Holders requesting
piggyback registration (which allocation shall be allocated pro rata among the
requesting Tichenor Holders based on the number of Registrable Securities
requested to be included in such registration) and (y) the remaining 50% of the
additional securities to be included shall be allocated pro rata among the
requesting Other Holders (excluding the shares included for the Tichenor
Holders pursuant to clause (x)) and Clear Channel (based upon the number of
Registrable Securities and other securities requested to be included in such
registration); and third, to the extent the Company is not the party initiating
such proposed underwritten offering and that any additional securities can, in
the opinion of such managing Underwriter or Underwriters, be sold without any
Material Adverse Effect, to the Company.

         4.      Holdback Agreements.

                 (a)      Restrictions on Public Sale by Clear Channel.  Clear
Channel agrees not to effect any public sale or distribution of Common Stock or
securities convertible into or exchangeable or exercisable for Common Stock,
including a sale pursuant to Rule 144 under the Securities Act, during the 14
days prior to, and during the 180-day period beginning on, the effective date
of a registration statement filed relating to a firm commitment underwritten
public offering of Common Stock or securities convertible into, or exchangeable
or exercisable for, Common Stock except as part of such registration if and to
the extent requested by the Company in the case of a nonunderwritten public
offering or if and to the extent requested by the managing Underwriter or
Underwriters in the case of an underwritten public offering.

                 (b)      Restrictions on Public Sale by the Company and
Others.  The Company agrees (i) not to effect any public sale or distribution
of any securities similar to those being registered or any securities
convertible into or exchangeable or exercisable for such securities other than
pursuant to a registration statement on Form S-8 or any successor form, during
the 14 days prior to, and during the 180-day period beginning on, the effective
date of any





                                      -5-
<PAGE>   142
registration statement which includes Registrable Securities (unless such sale
or distribution is pursuant to such registration statement pursuant to Section
3(b) or Clear Channel is participating in such registration statement pursuant
to Section 3 and such offering was initiated by the Company with respect to the
sale of securities by the Company) and (ii) that any agreement entered into
after the date of this Agreement pursuant to which the Company issues or agrees
to issue any privately placed securities shall contain a provision under which
holders of such securities agree not to effect any public sale or distribution
of any such securities during the period described in (i) above, including a
sale pursuant to Rule 144 under the Securities Act (except as part of any such
registration, if permitted); provided, however, that the provisions of this
paragraph (b) shall not prevent the conversion or exchange of any securities
pursuant to their terms into or for other securities.

                 (c)      Deferral of Filing.  The Company may defer the filing
(but not the preparation) of a registration statement required by Section 2
until a date not later than 90 days after the Required Filing Date if, at the
time the Company receives the Demand Request, the Company or its subsidiaries
are engaged in confidential negotiations or other confidential business
activities, disclosure of which would be required in such registration
statement (but would not be required if such registration statement were not
filed), and the Board of Directors of the Company determines in good faith that
such disclosure would be materially detrimental to the Company and its
stockholders. A deferral of the filing of a registration statement pursuant to
this Section 4(c) shall be lifted, and the requested registration statement
shall be filed forthwith, if the negotiations or other activities are disclosed
or terminated. In order to defer the filing of a registration statement
pursuant to this Section 4(c), the Company shall promptly, upon determining to
seek such deferral, deliver to Clear Channel a certificate signed by the
President of the Company stating that the Company is deferring such filing
pursuant to this Section 4(c) and the basis therefor in reasonable detail.
Within 20 days after receiving such certificate, may withdraw such request by
giving notice to the Company.  If withdrawn, the Demand Request shall be deemed
not to have been made for all purposes of this Agreement.  The Company may
defer the filing of a particular registration statement pursuant to this
Section 4(c) only once.

         5.      Registration Procedures.  The Company will, at its expense,
use all commercially reasonable efforts to effect the registration of any
Registrable Securities under the Securities Act in accordance with the intended
method of disposition thereof as quickly as practicable, and in connection with
any such request, the Company will as expeditiously as practicable:

                 (a)      prepare and file with the Commission a registration
statement on any form for which the Company then qualifies or which counsel for
the Company shall deem appropriate and which form shall be available for the
registration of the Registrable Securities to be registered thereunder in
accordance with the intended method of distribution thereof, and use all
commercially reasonable efforts and proceed diligently and in good faith to
cause such filed registration statement to become effective under the
Securities Act; provided that before filing a registration statement or
prospectus or any amendments or supplements thereto, the Company will furnish
to Clear Channel and to one counsel reasonably acceptable to the Company
selected by Clear Channel, copies of all such documents proposed to be filed,
which documents will be subject to the review of such counsel; provided,
further, that in connection with a Demand Registration, the Company shall not
file any registration statement or prospectus, or any





                                      -6-
<PAGE>   143
amendments or supplements thereto, if Clear Channel and its counsel shall
reasonably object, in writing, on a timely basis;

                 (b)      prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective pursuant to Section 2 for a period (except as provided in the last
paragraph of this Section 5) of not less than 180 consecutive days or, if
shorter, the period terminating when all Registrable Securities covered by such
registration statement have been sold (but not before the expiration of the
applicable period referred to in Section 4(3) of the Securities Act and Rule
174 thereunder, if applicable) and comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
method of disposition by Clear Channel set forth in such registration
statement;

                 (c)      furnish to Clear Channel such number of copies of
such registration statement, each amendment and supplement thereto (in each
case including all exhibits thereto), the prospectus included in such
registration statement (including each preliminary prospectus) and such other
documents as Clear Channel may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by Clear Channel;

                 (d)      notify Clear Channel promptly, and (if requested by
any such Person) confirm such notice in writing, (i) when a prospectus or any
prospectus supplement or post-effective amendment has been filed, and, with
respect to a registration statement or any post-effective amendment, when the
same has become effective under the Securities Act and each applicable state
law, (ii) of any request by the Commission or any other Federal or state
governmental authority for amendments or supplements to a registration
statement or related prospectus or for additional information, (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of a
registration statement or the initiation of any proceedings for that purpose,
(iv) if at any time the representations or warranties of the Company or any
subsidiary contained in any agreement contemplated by Section 5(i) below cease
to be true and correct in any material respect, (v) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale
in any jurisdiction or the initiation or threatening of any proceeding for such
purpose, (vi) of the happening of any event which makes any statement made in
such registration statement or related prospectus or any document incorporated
or deemed to be incorporated therein by reference untrue in any material
respect or that requires the making of any changes in such registration
statement, prospectus or documents so that, in the case of the registration
statement, it will not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, and that in the case of the prospectus,
it will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made
not misleading and (vii) of the Company's reasonable determination that a
post-effective amendment to a registration statement would be appropriate;

actions as are reasonably required in order to expedite or facilitate the
disposition of such Registrable Securities;

                 (j)      make available for inspection by Clear Channel and
any attorney, accountant or other professional retained by Clear Channel
(collectively, the "Inspectors"), all financial and other records, pertinent
corporate documents and properties of the Company (collectively, the "Records")
as shall be reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to

Inspectors unless (i) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in such registration statement or (ii) the
release of such Records is ordered pursuant to a subpoena or other order from a

comply with all applicable rules and regulations of the Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering a period of twelve months, beginning within three
months after the effective date of the registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act;

                 (m)      use all commercially reasonable efforts to cause all
such Registrable Securities to be listed on each securities exchange on which
similar securities issued by the Company are then listed or quoted on any
inter- dealer quotation system on which similar securities issued by the
Company are then quoted;

                 (n)      if any event contemplated by Section 5(d)(vi) above
shall occur, as promptly as practicable prepare a supplement or amendment or
post-effective amendment to such registration statement or the related
prospectus or any document incorporated therein by reference or promptly file
any other required document so that, as thereafter delivered to the purchasers
of the Registrable Securities, the prospectus will not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading; and

                 (o)      cooperate and assist in any filing required to be
made with the NASD and in the performance of any due diligence investigation by
Clear Channel.

                 The Company may require Clear Channel to promptly furnish in
writing to the Company such information regarding the distribution of the
Registrable Securities as it may from time to time reasonably request and such
other information as may be legally required in connection with such
registration.  Notwithstanding anything herein to the contrary, the Company
shall have the right to exclude from any offering the Registrable Securities of
Clear Channel if it does not comply with the provisions of the immediately
preceding sentence.

                 Clear Channel agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section
5(d)(vi), Clear Channel will forthwith discontinue disposition of Registrable
Securities pursuant to the registration statement covering such Registrable
Securities until Clear Channel's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 5(d)(vi), and, if so directed by the
Company, Clear Channel will deliver to the Company all copies, other than
permanent file copies, then in Clear Channel's possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such
notice.  In the event the Company shall give such notice, the Company shall
extend the period during which such registration statement shall be maintained
effective





                                      -9-
<PAGE>   146
(including the period referred to in Section 5(b)) by the number of days during
the period from and including the date of the giving of notice pursuant to
Section 5(d)(vi) to the date when the Company shall make available to Clear
Channel a prospectus supplemented or amended to conform with the requirements
of Section 5(d)(vi).

         6.      Registration Expenses.  Subject to the provisions in Section
2(b) above with respect to a Demand Registration, in connection with any Demand
Registration or Piggyback Registration, the Company shall pay the following
registration expenses (the "Registration Expenses"): (a) all registration and
filing fees (including, without limitation, with respect to filings to be made
with the NASD), (b) fees and expenses of compliance with securities or blue sky
laws (including reasonable fees and disbursements of counsel in connection with
blue sky qualifications of the Registrable Securities), (c) printing expenses,
(d) internal expenses of the Company (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), (e) the fees and expenses incurred in connection with the
listing on an exchange of the Registrable Securities if the Company shall
choose, or be required pursuant to Section 5(m) to list such Registrable
Securities, (f) reasonable fees and disbursements of counsel for the Company
and customary fees and expenses for independent certified public accountants
retained by the Company (including the expenses of any comfort letters
requested pursuant to Section 5(k)), (g) the reasonable fees and expenses of
any special experts retained by the Company in connection with such
registration,  (h) reasonable fees and expenses of one counsel reasonably
acceptable to the Company selected by Clear Channel incurred in connection with
the registration of such Registrable Securities hereunder and (i) fees and
expenses of any "qualified independent underwriter" or other independent
appraiser participating in an offering pursuant to Section 3 of Schedule E to
the Bylaws of the NASD.  The Company shall not have any obligation to pay any
underwriting fees, discounts, or commissions attributable to the sale of
Registrable Securities or  the fees and disbursements of counsel for any
Underwriter.

         7.      Indemnification; Contribution.

                 (a)      Indemnification by the Company.  The Company agrees
to indemnify and hold harmless Clear Channel, each Person, if any, who controls
Clear Channel within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act, and the officers, directors, agents, general and
limited partners, and employees of Clear Channel and each such controlling
person from and against any and all losses, claims, damages, liabilities, and
expenses (including reasonable costs of investigation) arising out of or based
upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus relating to the
Registrable Securities or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or expenses arise out of, or are based
upon, any such untrue statement or omission or allegation thereof based upon
information furnished in writing to the Company by Clear Channel or on Clear
Channel's behalf expressly for use therein; provided, however,  that with
respect to any untrue statement or omission or alleged untrue statement or
omission made in any preliminary prospectus, the indemnity agreement contained
in this paragraph shall not apply to the extent that any such loss, claim,
damage, liability or expense results from the fact that a current copy of





                                      -10-
<PAGE>   147
the prospectus was not sent or given to the Persons asserting any such loss,
claim, damage, liability or expense at or prior to the written confirmation of
the sale of the Registrable Securities concerned to such Person if it is
determined that (i) it was the responsibility of Clear Channel or any
Underwriter or dealer for Clear Channel to provide such person with a current
copy of the prospectus, (ii) Clear Channel was provided with a current copy of
the prospectus prior to the written confirmation of sale and (iii) such current
copy of the prospectus would have cured the defect giving rise to such loss,
claim, damage, liability or expense.  The Company also agrees to indemnify any
Underwriters of the Registrable Securities, their officers and directors and
each Person who controls such Underwriters on substantially the same basis as
that of the indemnification of Clear Channel provided in this Section 7(a).

                 (b)      Indemnification by Clear Channel.  Clear Channel
agrees to indemnify and hold harmless the Company, and each Person, if any, who
controls the Company within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act and the officers, directors, agents and
employees of the Company and each such controlling Person to the same extent as
the foregoing indemnity from the Company to Clear Channel, but only with
respect to information furnished in writing by Clear Channel or on Clear
Channel's behalf expressly for use in any registration statement or prospectus
relating to the Registrable Securities.  The liability of Clear Channel under
this Section 7(b) shall be limited to the aggregate cash and property received
by Clear Channel pursuant to the sale of Registrable Securities covered by such
registration statement or prospectus.

                 (c)      Conduct of Indemnification Proceedings.  If any
action or proceeding (including any governmental investigation) shall be
brought or asserted against any Person entitled to indemnification under
Section 7(a) or 7(b) above (an "Indemnified Party") in respect of which
indemnity may be sought from any party who has agreed to provide such
indemnification under Section 7(a) or 7(b) above (an "Indemnifying Party"), the
Indemnified Party shall give prompt notice to the Indemnifying Party and the
Indemnifying Party shall assume the defense thereof, including the employment
of counsel reasonably satisfactory to such Indemnified Party, and shall assume
the payment of all reasonable expenses of such defense. Such Indemnified Party
shall have the right to employ separate counsel in any such action or
proceeding and to participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party unless (i)
the Indemnifying Party has agreed to pay such fees and expenses, or (ii) the
Indemnifying Party fails promptly to assume the defense of such action or
proceeding or fails to employ counsel reasonably satisfactory to such
Indemnified Party or (iii) the named parties to any such action or proceeding
(including any impleaded parties) include both such Indemnified Party and
Indemnifying Party (or an Affiliate of the Indemnifying Party), and such
Indemnified Party shall have been advised by counsel that there is a conflict
of interest on the part of counsel employed by the Indemnifying Party to
represent such Indemnified Party (in which case, if such Indemnified Party
notifies the Indemnifying Party in writing that it elects to employ separate
counsel at the expense of the Indemnifying Party, the Indemnifying Party shall
not have the right to assume the defense of such action or proceeding on behalf
of such Indemnified Party).  Notwithstanding the foregoing, the Indemnifying
Party shall not, in connection with any one such action or proceeding or
separate but substantially similar related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable at any time for the fees and





                                      -11-
<PAGE>   148
expenses of more than one separate firm of attorneys (together in each case
with appropriate local counsel for the Indemnified Party).  The Indemnifying
Party shall not be liable for any settlement of any such action or proceeding
effected without its written consent (which consent will not be reasonably
withheld), but if settled with its written consent, or if there be a final
judgment for the plaintiff in any such action of proceeding, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Party from and against
any loss or liability (to the extent stated above) by reason of such settlement
or judgment.  The Indemnifying Party shall not consent to entry of any judgment
or enter into any settlement that does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release, in form and substance satisfactory to the Indemnified Party, from all
liability in respect of such action or proceeding for which such Indemnified
Party would be entitled to indemnification hereunder.

                 (d)      Contribution. If the indemnification provided for in
this Section 7 is unavailable to the Indemnified Parties in respect of any
losses, claims, damages, liabilities or judgments referred to herein, then each
such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses, claims, damages, liabilities and judgments as between the
Company on the one band and Clear Channel on the other, in such proportion as
is appropriate to reflect the relative fault of the Company and of Clear
Channel in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations.  The relative fault of the Company on the
one hand and of Clear Channel on the other shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by such party, and the parties relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Company and Clear Channel agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately
preceding paragraph.  The amount paid or payable by an Indemnified Party as a
result of the losses, claims, damages, liabilities or judgments referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such Indemnified Party in connection with investigating or defending any such
action or claim.  Notwithstanding the provisions of this Section 7(d), Clear
Channel shall not be required to contribute any amount in excess of the amount
by which the total price at which its Registrable Securities were offered to
the public exceeds the amount of any damages which it has otherwise been
required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled
to contribution from any Person who was not guilty of such fraudulent
misrepresentation.

         8.      Participation in Underwritten Registrations.  Clear Channel
may not participate in any underwritten registration hereunder unless it (a)
agrees to sell its Registrable Securities





                                      -12-
<PAGE>   149
on the basis provided in any underwriting arrangements approved by the Person
entitled hereunder to approve such arrangements, (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements and this Agreement, and (c) if requested by another Person
participating in such underwritten registration, provides that all securities
convertible or exchangeable into Common Stock that are included in such
underwritten registration shall be so converted or exchanged on or prior to the
consummation thereof.

         9.      Marketing of Securities.  Upon the registration of any
Registrable Securities pursuant to the terms of this Agreement, the Company
shall use all commercially reasonable efforts to participate in and cooperate
with the managing Underwriter or Underwriters in the marketing of such
Registrable Securities, including, but not limited to, participating in any
sales force presentations and any "roadshow" or other marketing presentations
deemed necessary by the managing Underwriter or Underwriters to market such
securities.

         10.     Additional Registration Rights.  The Company shall not on or
after the date of this Agreement enter into any agreement granting registration
rights to any other Person with respect to the securities of the Company, that
are demand registration rights of the type described in Section 2 and do not
rank pari passu or subordinate to the rights granted under Section 2, or with
respect to any piggyback registration rights of the type described in Section
3, that are not pari passu or subordinate to the rights granted to Clear
Channel hereunder, without the prior written consent of Clear Channel.  Any
agreement entered into pursuant to such consent shall not be amended without a
further written consent of Clear Channel.  The Company represents and warrants
to Clear Channel that the Company has not granted registration rights to any
other Person with respect to the securities of the Company other than pursuant
to that certain Registration Rights Agreement of even date herewith among the
Company and McHenry T. Tichenor, Sr., McHenry T.  Tichenor, Jr., Warren W.
Tichenor, William E. Tichenor, Jean T. Russell, McHenry T, Tichenor, Jr., as
Custodian for David T. Tichenor, Alta Subordinated Debt Partners III, L.P., a
Delaware limited partnership, Prime II Management, L.P., a Delaware limited
partnership, PrimeComm, L.P., A Delaware limited partnership, Ricardo A. del
Castillo, Jeffrey T.  Hinson and David D. Lykes.

         11.     Amendments and Waivers.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given without the written consent of the Company, Clear Channel and,
so long as the Tichenor Holders own at least 15% of the Common Stock
(calculated assuming all securities held by Clear Channel exercisable or
exchangeable for or convertible into Class B Common Stock have been so
exercised, exchanged or converted and the Class B Common Stock subject thereto
is outstanding and by treating the Class B Common Stock of the Company as
converted into Common Stock), the holders of at least a majority of the then
outstanding "Registrable Securities" (as defined in the Tichenor Registration
Rights Agreement).

                 d.       Shareholder has not entered into any agreement,
         arrangement or understanding with any person or firm which will result
         in the obligation of any person to pay any finder's fees, brokerage or
         agent's commission or other like payments in connection with the
         negotiations leading to this Agreement or the consummation of the

RESPECTS, INCLUDING VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS OF THE

         NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties to this Agreement
hereby agree as follows:

         2.      Representations and Warranties by Shareholder.  Shareholder
represents and warrants to Parent that:

                 a.       As of the Closing, Shareholder will be the sole
         record and beneficial owner of the Shares; no person will have a right
         to acquire or direct the disposition, or hold a proxy or other right
         to vote or direct the vote, of such Shares; and Shareholder will have
         good title to such Shares, free and clear of any agreements,
         restrictions, liens, adverse claims or encumbrances whatsoever.  As of
         the Closing, other than this Agreement and the Merger Agreement there
         will be no option, warrant, right, call, proxy, agreement, commitment
         or understanding of any nature whatsoever, fixed or contingent, that
         directly or indirectly (i) calls for the sale, pledge or other
         transfer or disposition of any of such Shares, any interest therein or
         any rights with respect thereto, or relates to the voting,
         disposition, exercise, conversion or control of such Shares, or (ii)
         obligates Shareholder to grant, offer or enter into any of the
         foregoing.

                 b.       The sale by Shareholder of such Shares and the
         delivery of the certificates representing such Shares to Parent
         against receipt of payment therefor pursuant hereto will transfer to
         Parent indefeasible title to such Shares, free and clear of all
         agreements, trusts, liens, adverse claims and encumbrances whatsoever.

                 c.       Shareholder has the full right, power, authority and
         legal capacity to enter into this Agreement.

                 d.       Shareholder has not entered into any agreement,
         arrangement or understanding with any person or firm which will result
         in the obligation of any person to pay any finder's fees, brokerage or
         agent's commission or other like payments in connection with the
         negotiations leading to this Agreement or the consummation of the
         transactions contemplated hereby.

         3.      Covenants by Shareholder.  Shareholder hereby covenants and
agrees that it will not enter into any transaction, take any action or by
inaction permit any event to occur that would result in any of its
representations or warranties herein contained not being true and correct at
and as of (i) the time immediately after the occurrence of such transaction,
action or event and (ii) the date of the Closing.

         4.      Representations by Parent.  Parent hereby represents and
warrants to Shareholder that Parent is an "accredited investor" (as such term
is defined in Regulation D promulgated under the Securities Act of 1933, as
amended), and that the Shares are being acquired with investment intent and not
with a view to resale.

         5.      Closing; Conditions to Closing.  The closing of the sale to
and purchase by Parent of the Shares (the "CLOSING") shall occur at the offices
of Akin, Gump, Strauss, Hauer & Feld, L.L.P., 1700 Pacific Avenue, Suite 4100,
Dallas, TX 75201, or such other place agreed to by the parties hereto,
immediately prior to the closing of the Merger (the "CLOSING DATE").  The
Closing shall be conditioned upon, unless waived by Parent in its sole
discretion, (a) each of the representations and warranties made by Shareholder
in this Agreement being true and correct in all material respects at and as of
the time of Closing; (b) Shareholder having performed in

all material respects each and every covenant and agreement contained in this
Agreement required to be performed by it by the time of Closing; and (c) all
conditions set forth in the Merger Agreement being satisfied or waived prior to
the closing of the Merger.

         6.      Severability.  Any term or provision of this Agreement that is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction.  If any provision of
this Agreement is so broad as to be unenforceable, such provision shall be
interpreted to be only so broad as is enforceable.

         7.      APPLICABLE LAW.  THIS AGREEMENT SHALL BE GOVERNED IN ALL
RESPECTS, INCLUDING VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS OF THE
STATE OF TEXAS REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER
APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.

         8.      Expenses.  Whether or not the transactions contemplated by
this Agreement are consummated, each of the parties hereto shall pay its
respective fees and expenses incurred in connection herewith.

         9.      Entire Agreement.  This Agreement (together with the documents
and instruments received by the parties in connection with this Agreement)
constitutes the entire agreement and supersedes all other prior agreements and
understandings, both written and oral, between the parties hereto with respect
to the subject matter hereof.

         10.     Amendments.  This Agreement may not be amended or modified
except by a written instrument signed on behalf of each of the parties hereto.

         11.     Assignment; Binding Effect.  Nothing contained in this
Agreement shall be deemed to prohibit Parent from assigning its rights to any
of its affiliates.  Any such assignment shall not relieve Parent from its
obligations hereunder.  This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns.

         12.     Notices.  Any notice or other communication required or
permitted hereunder shall be in writing and either delivered personally, by
