(a) All licenses, construction permits or authorizations issued by or
pending before the FCC or any other governmental authority for use in the
operation of the Station that are set forth on Schedule I attached hereto,
together with any and all renewals, extensions and modifications thereof (the

2. CONSIDERATION; CLOSING.

2.1 PURCHASE PRICE; RESERVE.

(a) The consideration to be received by the Seller in exchange for
the Station Assets shall be $20,290,000 in cash. The Purchaser and Seller
agree to allocate the foregoing purchase price for federal income tax
purposes among the Station Assets in a manner not inconsistent with Section
1060 of the Internal Revenue Code of 1986, as amended, and the related
Treasury Regulations issued thereunder. The Purchaser shall bear the costs
of obtaining appraisals, if any such appraisals are required to be obtained
by the Purchaser, of the Station Assets. Such appraisals shall be made by
Bond & ▇▇▇▇▇▇, or such other qualified appraisers selected by the Purchaser.

(b) At the Closing, the Seller shall set aside and pay to Purchaser a
portion of the purchase price in the amount of $50,000, which the Purchaser
shall use in its sole discretion as a reserve (the "Reserve") in order to
satisfy certain obligations in connection with the Assumed Contracts.

2.2 TIME OF CLOSING.

(a) A closing (the "Closing") for the sale and purchase of the
Station Assets shall be held at the offices of the Station in Las Vegas,
Nevada (or such other place as may be agreed upon by the parties in writing)
on the date which is the later of (i) the 5th day after the FCC Order (as
defined hereinafter) or (ii) the satisfaction of all of the conditions
precedent to the obligations of Purchaser and Seller hereunder, or on such
other date as may be agreed upon by the parties in writing (the "Closing
Date"). The Closing shall be deemed to be effective as of 12:01 a.m. on the
Closing Date.

(b) In order to consummate the transfer of the Station Assets, Seller
and Purchaser agree to use their best efforts to file, within five days after
the date hereof, an assignment of license application (the "Application")
requesting FCC consent to the assignment from the Seller to Purchaser of all
Governmental Licenses relating to the operation of the Station. The parties
agree that the Application will be prosecuted with best reasonable efforts,
in good faith and with due diligence. The parties agree to use their
reasonable best efforts to file additional information or amendments
requested by the FCC orally or in writing within five business days after
such request and, in any event, to commence preparation of such additional
information or amendments immediately upon request and to complete and file
the same with the FCC as rapidly as practical. Each party will be solely
responsible for the expenses incurred by it in the preparation, filing and
prosecution of the Application (it being understood that the parties will
bear equally the FCC filing fee). As used herein, the term "FCC Order" shall
mean that the FCC staff has granted or given its consent, without any
condition materially adverse to Purchaser or Seller, to the assignment of the
Governmental Licenses; and the term "Final Order" shall mean that the FCC
Order shall have become final, that the time period for filing any protests,
requests for stay, reconsideration by the FCC, petitions for rehearing or
appeal of such order shall have expired, and that no protest, request for
stay, reconsideration by the FCC, petition for rehearing or appeal of such
order shall be pending.

(c) To the extent required by the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust
Improvements Act of 1976, as amended, and the rules and regulations
promulgated thereunder (the "HSR Act"), the parties further agree to use
their best efforts to make any necessary filings under the HSR Act. The fees
associated with any filings made pursuant to the HSR Act shall be paid by the
Purchaser.

2.3 CLOSING PROCEDURE. At the Closing, the Seller shall deliver to
Purchaser such bills of sale, instruments of assignment, transfer and
conveyance and similar

documents as Purchaser shall reasonably request. Against such delivery,
Purchaser shall (i) issue and deliver to Seller the purchase price in
accordance with Section 2.1 above and (ii) execute and deliver the assumption
agreements with respect to the Assumed Contracts as are contemplated by
Section 1.2 hereof. Each party will cause to be prepared, executed and
delivered all other documents required to be delivered by such party pursuant
to this Agreement and all other appropriate and customary documents as
another party or its counsel may reasonably request for the purpose of
consummating the transactions contemplated by this Agreement. All actions
taken at the Closing shall be deemed to have been taken simultaneously at the
time the last of any such actions is taken or completed.

or any order, writ, injunction or decree of any court or governmental
authority, which violation, either individually or in the aggregate, might
reasonably be expected to have a material adverse effect on the business or
operations of the Seller or Purchaser's ownership of the Station Assets; or
(iii) violate or conflict with or constitute a default under (or give rise to
any right of termination, cancellation or acceleration under), or result in

bound or affected.

occurred which (whether with or without notice, lapse of time or the
happening or occurrence of any other event) is reasonably likely to result in
the revocation or termination of any Governmental License or the imposition
of any restriction of such a nature as might adversely affect the ownership
or operation of the Station as now conducted, except for proceedings of a
legislative or rule-making nature intended to affect the broadcasting
industry generally.

filed by law or applicable rule, regulation, order, writ or decree of any
court, governmental commission, body or instrumentality and has made payment
of all charges and other payments, if any, shown by such reports to be due

not material); (ii) Seller has not received any written notice of any
examinations or audits pending or unresolved examinations or audit issues
with respect to the Seller's federal, state or local tax returns; (iii) all
additional taxes, if any, assessed as a result of such examinations or audits

administrative or otherwise that is pending or, to Seller's and Shareholder's
knowledge, threatened against or affecting the Station which, if adversely
determined, might materially and

adversely affect the business, operations, properties, assets or conditions
(financial or otherwise) of the Station or which challenges the validity or
propriety of any of the transactions contemplated by this Agreement.

3.10 THIRD PARTY CONSENTS. By the Closing Date, the Seller will have

12. GENERAL RULES REGARDING INDEMNIFICATION.

The obligations and liabilities of each indemnifying party hereunder
with respect to claims resulting from the assertion of liability by the other
party or indemnified third parties shall be subject to the following terms
and conditions:

(a) The indemnified party shall give prompt written notice (which in
no event shall exceed 30 days from the date on which the indemnified party
first became aware of such claim or assertion) to the indemnifying party of
any claim which might give rise to a claim by the indemnified party against
the indemnifying party based on the indemnity agreements contained in Section
10 or 11 hereof, stating the nature and basis of said claims and the amounts
thereof, to the extent known;

(b) If any action, suit or proceeding is brought against the
indemnified party with respect to which the indemnifying party may have
liability under the indemnity agreements contained in Section 10 or 11
hereof, the action, suit or proceeding shall, upon the written acknowledgment
by the indemnifying party that it is obligated to indemnify under such
indemnity agreement, be defended (including all proceedings on appeal or for
review which counsel for the indemnified party shall deem appropriate) by the
indemnifying party. The indemnified party shall have the right to employ its
own counsel in any such case, but the fees and expenses of such counsel shall
be at the indemnified party's own expense unless (A) the employment of such
counsel and the payment of such fees and expenses both shall have been
specifically authorized in writing by the indemnifying party in connection
with the defense of such action, suit or proceeding, or (B) counsel to such
indemnified party shall have reasonably concluded and specifically notified
the indemnifying party that there may be specific defenses available to it
which are different from or additional to those available to the indemnifying
party or that such action, suit or proceeding involves or could have an
effect upon matters beyond the scope of the indemnity agreements contained in
Sections 10 and 11 hereof, in any of which events the indemnifying party, to
the extent made necessary by such defenses, shall not have the right to
direct the defense of such action, suit or proceeding on behalf of the
indemnified party. In the latter such case only that portion of such fees
and expenses of the indemnified party's separate counsel reasonably related
to matters covered by the indemnity agreements contained in Section 10 or 11
hereof shall be borne by the indemnifying party. The indemnified party shall
be kept fully informed of such action, suit or proceeding at all stages
thereof whether or not it is represented by separate counsel.

(c) The indemnified party shall make available to the indemnifying
party and its attorneys and accountants all books and records of the
indemnified party relating to such proceedings or litigation and the parties
hereto agree to render to each other such assistance as they may reasonably
require of each other in order to ensure the proper and adequate defense of
any such action, suit or proceeding.

(d) The indemnified party shall not make any settlement of any claims
without the written consent of the indemnifying party, which consent shall
not be unreasonably withheld or delayed.

(e) If any claims are made by third parties against an indemnified
party for which an indemnifying party would be liable, and it appears likely
that such claims might also be covered by the indemnified party's insurance
policies, the indemnified party shall make a timely claim under such policies
and to the extent that such party obtains any recovery from such insurance,
such recovery shall be offset against any sums due from an indemnifying party
(or shall be repaid by the indemnified party to the extent that an
indemnifying party has already paid any such amounts). The parties
acknowledge, however, that if an indemnified party is self-insured as to any
matters, either directly or through an insurer which assesses retroactive
premiums based on loss experience, then to the extent that the indemnified
party bears the economic burden of any claims through self-insurance or
retroactive premiums or insurance ratings, the indemnifying party's
obligation shall only be reduced by any insurance recovery in excess of the
amount paid or to be paid by the indemnified party in insurance premiums.

(f) The indemnified party shall not make any claim unless and until
it has incurred indemnified losses, damages and expenses in the cumulative
aggregate amount of $25,000, and then only in respect of the excess over such
$25,000 minimum.

(g) Except as herein expressly provided, the remedies provided in
Sections 10 through 12 hereof shall be cumulative and shall not preclude
assertion by any party of any other rights or the seeking of any other rights
or remedies against any other party hereto.

13. TERMINATION. This Agreement may be terminated by the mutual consent of
Purchaser and Seller, or by either Purchaser or Seller, if the terminating
party is not then in material breach of its obligations hereunder, upon
written notice to the other upon the occurrence of any of the following:

(a) By the terminating party, if the other party is in material
breach of its obligations hereunder, and such breach has not been cured by
the other party within 30 days of written notice of such breach (or such
longer period of time if the breach

cannot be reasonably cured within 30 days and the breaching party is
diligently attempting to cure such breach);

(b) If the FCC designates the FCC Application contemplated by Section
2.2(b) hereof for hearing at any time; or

In the event that this Agreement is terminated as a result of either party's
material breach of this Agreement, the non-breaching party will incur
substantial damages that are difficult to quantify. In such event, the sum
of $2,000,000 (the "Break-up Fee") is deemed by the parties to be an amount
which is a fair and reasonable estimate of the damage the non-breaching party
may incur. Accordingly, in the event of such termination, the breaching
party will pay the Break-up Fee to the non-breaching party within 10 days of
such termination; provided, however, that the Shareholder shall not have any
personal liability for such payment (it being understood that the Company
will be solely liable in the event that the Company and/or the Shareholder
are the breaching party).

14. RISK OF LOSS. The Seller shall bear the risk of all damage to, loss of
or destruction of any of the Station Assets between the date of this
Agreement and the Closing Date. If any material portion of the Station
Assets shall suffer any material damage or destruction prior to the Closing
Date, the Seller shall promptly notify the Purchaser in writing of such
damage or destruction, shall promptly take all necessary steps to restore,
repair or replace such assets at its sole expense, and shall advise the
Purchaser in writing of the estimated cost to complete such restoration,
repair or replacement and all amounts actually paid as of the date of the
estimate. The Purchaser or Seller may extend the Closing Date for a period
not exceeding 45 days to accomplish such restoration, repair or replacement,
but is not required to do so. If such restoration, repair or replacement is
not accomplished prior to the Closing Date, as the same may be extended as
provided herein, the Purchaser may, at its option:

(a) terminate this Agreement upon written notice to Seller; or

(b) receive all insurance proceeds paid or payable to Seller close
this Agreement and thereafter complete such restoration, repair or
replacement at its sole expense; provided, however, Seller shall have no
further liabilities with respect to such damage or destruction after payment
to Purchaser of such insurance proceeds.

15. MISCELLANEOUS PROVISIONS.

15.1 EXPENSES. Except as otherwise expressly provided herein, each
party shall pay the fees and expenses incurred by it in connection with the
transactions contemplated by this Agreement. If any action is brought for
breach of this

Agreement or to enforce any provision of this Agreement, the prevailing party
shall be entitled to recover court costs and reasonable attorneys' fees.

15.2 PRORATIONS. All items of income and expense arising from the
operation of the Station with respect to the Station Assets and the Assumed
Contracts on or before the close of business on the Closing Date shall be for
the account of the Seller and thereafter shall be for the account of the
Purchaser. Proration of the items described below between the Seller and the
Purchaser shall be effective as of 11:59 p.m., local time, on such date and
shall occur as follows with respect to those rights, liabilities and
obligations of the Seller transferred to and assumed by the Purchaser
hereunder.

(a) Liability for state and local taxes assessed on the Station
Assets payable with respect to the tax year in which the Closing Date falls
and the annual FCC regulatory fee for the Station payable with respect to the
year in which the Closing Date falls shall each be prorated as between the
Seller and the Purchaser on the basis of the number of days of the tax year
elapsed to and including such date.

(b) Prepaid items, deposits, credits and accruals such as water,
electricity, telephone, other utility and service charges, lease expenses,
license fees (if any) and payments under any contracts to be assumed by the
Purchaser shall be prorated between the Seller and the Purchaser on the basis
of the period of time to which such liabilities, prepaid items and accruals
apply.

All prorations shall be made and paid insofar as feasible on the Closing
Date; any prorations not made on such date shall be made as soon as
practicable (not to exceed 90 days) thereafter. The Seller and the
Purchaser agree to assume, pay and perform all costs, liabilities and
expenses allocated to each of them pursuant to this Section 15.2.

15.3 AMENDMENT. This Agreement may be amended at any time but only by
an instrument in writing signed by the parties hereto (it being understood

Schedule V

During the last license period, questions had been raised by the FCC
concerning electromagnetic fields and radio frequency radiation (RFR) at the
transmitter and the site's compliance with the ANSI standards ("Safety Levels
with respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3
kHz to 300GHz"). As a result, there was a joint study and a joint effort by
the affected licensees at the transmitter site to resolve the issue to the
FCC's satisfaction.

It is Seller's belief that the matter was resolved to the FCC's
satisfaction by the relocation of one transmitter to a different site and the
placing of warning signs concerning certain restricted areas.

EXHIBIT A

UNWIND AGREEMENT

The Unwind Agreement ("Agreement") is entered as of [closing date], by and
among Radio Vision, Inc., a Nevada corporation ("Seller"), HBC Las Vegas,
Inc., a Delaware corporation ("Asset Buyer") and HBC License Corp., a
Delaware corporation ("License Buyer"), which hereby agree as follows:

1. RECITALS.

(a) Heftel Broadcasting Corporation ("Heftel") and Seller entered into
an Asset Purchase Agreement ("Purchase Agreement") dated as of March 1, 1999,
providing for the sale and assignment to Asset Buyer, subject to approval by
the Federal Communications Commission (the "Commission"), of assets (the
"Station Assets") relating to Seller's radio station KISF-FM (the "Station"),
including the licenses issued by the Commission (the "Licenses")for the
operation of the Station. Heftel has assigned its rights under the Purchase
Agreement (i) to purchase the Licenses to License Buyer and (ii) to purchase
the remaining Station Assets to Asset Buyer. All capitalized terms not
otherwise defined herein shall have the meaning given to them in the Purchase
Agreement.

(b) The Commission has issued an order consenting (the "FCC Order") to
the assignment of the Licenses to License Buyer, but the FCC Order has not
yet become final and is still subject to Commission reconsideration and
judicial review; and

(c) Seller, Asset Buyer and License Buyer believe to to be desirable and
in the public interest that the transactions provided for in the Purchase
Agreement be consummated promptly; provided, however, that subject to
Commission approval, Seller, Asset Buyer and License Buyer desire to make
provision for the retransfer to Seller (or its assignees or designees) of the
Licenses and other Station Assets.

(d) In order to protect the interests of Seller, Asset Buyer and License
Buyer in the event a retransfer is necessary, the parties to this Agreement
have agreed upon the terms under which each shall act until the FCC Order
becomes a Final Order or in the event that a retransfer of the Licenses or
the other Station Assets is necessary.

2. CLOSING OF PURCHASE AGREEMENT. Seller, Asset Buyer and License Buyer
agree that:

(a) The Closing under the Purchase Agreement shall occur and be
effective as of the date hereof ("Closing Date"), and the purchase by Asset
Buyer and License Buyer of the Station Assets (the "Purchase") for the
Station shall be subject to revocation or rescission (a "Rescission Event")
if the FCC Order is set aside and there is a final and unappealable order of
the Commission returning, or requiring the

reassignment of, the Licenses to Seller or otherwise materially and adversely
affecting Asset Buyer's and License Buyer's right to broadcast on the Station,
or own the Licenses.

(b) To the extent any of the actions contained herein are inconsistent
with any statute, law or any Commission rule or regulation, the parties agree
to conform this Agreement to the Commission's requirements.

3. FCC DENIAL AND RESCISSION OF TRANSACTION.

(a) If a Rescission Event occurs, it is the intent of Seller, Asset
Buyer and License Buyer that the sale of the Station Assets consummated at
Closing pursuant to the Purchase Agreement shall be rescinded in a manner
that shall, as nearly as practicable in the circumstances, restore to the
respective parties the respective rights, titles and interests enjoyed by
each of them immediately prior to Closing in and to the cash, properties,
rights and interests which were transferred at Closing. Accordingly, upon the
occurrence of Rescission Event, the Seller, Asset Buyer and License Buyer
agree promptly and in good faith to extend such cooperation, execute such
instruments, and generally take such action as may be needed to formulate and
implement a rescission of the transaction and reassignment of rights and
obligations which effectively carries out the intent of Seller, Asset Buyer
and License Buyer as hereinabove expressed, including without limitation,
submitting to the Commission the requisite applications for consent to the
assignment of the Station Assets from Asset Buyer and License Buyer to Seller
(the "Unwind Application") within seven business days after the event or
deadline requiring the unwinding of the transactions contemplated by the
Purchase Agreement. The unwind closing shall occur within 15 days after the
Commission public notice is issued that the Commission (whether by delegated
authority or at the Commission level) has given its initial consent to the
Unwind Application.

(b) In the event a rescission is necessary, it is agreed that Asset
Buyer and License Buyer shall retain for their own account any profit (and
shall be fully responsible for any loss) relating to the operations of the
Station during the period from the Closing Date to 12:01 AM on the effective
date of rescission. It is further agreed that Asset Buyer and License Buyer
shall be responsible for all accounts payable, expenses and other obligations
through 12:01 AM on the effective date of rescission attributable to the
operation of the Station during the period from the Closing Date to 12:01 AM
on the effective date of rescission.

4. REPAYMENT OF PURCHASE PRICE. In connection with any rescission of
the Purchase after a Rescission Event, Seller agrees to pay to Asset Buyer
and License Buyer at the unwind closing the purchase price delivered to
Seller for the Station (the "Reimbursement"). Asset Buyer and License Buyer
agree that upon receipt of the

Reimbursement to return the Station Assets to the Seller in substantially the
same condition as such Station Assets exist on the date hereof, ordinary wear
and tear excepted.

5. INDEMNIFICATION. Seller agrees to indemnify, defend and hold
harmless Asset Buyer and License Buyer and its officers, directors,
successors, assigns and representatives from and against any and all
demands, losses, damages (excluding any and all special, consequential or
incidental damages), fines, penalties, causes of action, claims, liabilities,
obligations, judgments, costs or expenses (including, without limitation,
attorneys' fees and court costs) (hereinafter all of the foregoing being
referred to collectively or individually as "Claim"), claimed against,
incurred, suffered or sustained by it, him or them, or any of them, arising
out of, caused by, incident to or in any manner connected with the rescission
of the Purchase, unless such Claim is caused in whole or in part by the gross
negligence or willful misconduct of Asset Buyer and License Buyer. Asset
Buyer and License Buyer agree to indemnify the Seller for any Claim arising
out of a breach by Asset Buyer and License Buyer of this Agreement and for
any Claim arising out of the operations of the Station Assets by Asset Buyer
and License Buyer after the Closing Date through the date of the unwind
closing, unless such Claim is caused in whole or in part by the gross
negligence or willful misconduct of Seller.

6. COVENANTS OF ASSET BUYER AND LICENSE BUYER. From and after the date
hereof and up to the date the FCC Order becomes a Final Order or such later
date for retransfer of the Licenses and other Station Assets as contemplated
in Section 3 and 4 hereof, and except as specifically agreed to in writing by
Seller, Asset Buyer and License Buyer covenant and agree that, with respect
to the Station and the Station Assets, License Buyer shall not, by any act or
omission within its control, surrender, modify, forfeit or fail to maintain
or renew under regular terms the Licenses, cause the Commission to institute
any proceeding for the revocation, suspension or modification of any such
License, or fail to prosecute with due diligence any pending applications
with respect to the Licenses.

7. NOTICES. All notices, demands and requests required or permitted to
be given under the provisions of this Unwind Agreement shall be in the manner
set forth in the Purchase Agreement.

8. EFFECT OF AGREEMENT. This Agreement shall be binding on, inure to
the benefit of and be enforceable by Asset Buyer, License Buyer and Seller
and their respective heirs, successors and assigns.

9. SECTION AND PARAGRAPH HEADINGS. The section and paragraph headings
contained in this Agreement are for reference purposes only and shall not
affect in any way the meaning or interpretation of this Agreement.

10. GOVERNING LAW. This Agreement shall be construed and enforced in
accordance with the laws of the State of Nevada.

11. COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument.

12. ENTIRE AGREEMENT. Except as expressly set forth herein, the terms
of the Asset Purchase Agreement shall not be amended or modified in any
respect. Except for the Asset Purchase Agreement and the agreements referenced
therein, this Agreement contains all the terms and conditions agreed upon by
the parties hereto with respect to the transaction contemplated hereby, and
shall not be amended or modified except by written instrument signed by all
of the parties.

13. ASSIGNMENT. Any assignment of the rights and duties under this
Agreement by Asset Buyer and License Buyer, on the one hand, or Seller, on
the other, may be made only with the prior written approval of the other
party.

14. ATTORNEYS' FEES. If any action is brought for breach of this
Agreement or to enforce any provision of this Agreement, the prevailing
party shall be entitled to recover court costs, arbitration expenses and
reasonable attorneys' fees.
