THIS AGREEMENT is made and entered into this _____ day of March, 1993, by and

of WKKB, Inc., and has further granted Secured Party option whereby Secured
Party can resell said forty-nine (49) shares of stock back to Debtor, pursuant
to terms and conditions set forth in a Put Option Agreement between the parties
of even date herewith; and

WHEREAS, in order to induce Secured Party to acquire said shares, Debtor has
agreed to grant Secured Party a security interest in certain stock as provided
hereinafter to secure Debtor's obligation to repurchase said shares pursuant to
the Put Option Agreement.

NOW, THEREFORE, WITNESSETH that in consideration of the mutual promises and
covenants hereinafter stipulated, and good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
agree as follows.

1.   In consideration of Secured Party's agreement to acquire forty-nine (49)
shares of stock of WKKB, Inc. from Debtor, and other good and valuable
consideration granted by Secured Party to Debtor and Guarantor, Debtor has
granted Secured Party an option to resell said shares to Debtor for the sum of
Twenty Thousand Dollars ($20,000), and to secure said obligation of Debtor to
repurchase said shares, Debtor hereby pledges, hypothecates and assigns to
Secured Party, and grants Secured Party a continuing security interest in the
following described stock:

        Fifty-one (51) shares of common stock of WKKB, Inc., 
        owned by Debtor, as evidenced by certificate no. 1,

together with any and all substitutions, replacements and proceeds thereof,
including, without limitation, any stock rights, stock dividends, cash or
property dividends, liquidating dividends, new securities and other property to
which Debtor may become entitled by reason of ownership of the property
described above and which, if received by Debtor, shall be held in trust and
forthwith delivered to Secured Party to be held hereunder.  Debtor hereby
agrees to execute a stock power in the name of Secured Party for the stock
described hereinabove, and to deliver the above-described stock certificate and
stock power to Secured Party upon the execution hereof for Secured Party to
hold as collateral hereunder.

2.   Secured Party is hereby authorized by Debtor, in the event of default
under the terms of this Agreement or the Note secured hereby, without prior
notice to Debtor, to cause the property pledged hereunder (or any part thereof)
to be transferred to and registered in the name of Secured Party, or in the
name of any other person or entity designated by Secured Party, and to notify
any persons or entities who may be obligated on the property pledged hereunder
to thereafter make any payments required thereunder to Secured Party.  Secured
Party shall have the right to deliver all or any part of the property pledged
hereunder to any other person or entity, whereupon such transferee shall become
vested with all of Secured Party's rights and powers hereunder, and Secured
Party shall thereafter forever be fully released and discharged from any
liability or responsibility hereunder or by reason of such transfer.

3.   Debtor represents and warrants that he is the legal and beneficial owner
of the property pledged hereunder; that such property represents fifty-one
percent (51%) of the issued and outstanding capital stock of WKKB, Inc., and
that the total authorized capital stock of WKKB, Inc.  consists of one hundred
(100) shares of common stock;  that said property was validly issued, is fully
paid and is nonassessable; that said property is not encumbered nor subject to
restrictions on transfer or sale or other disposition in any manner whatsoever
(other than pursuant to applicable securities laws); that Debtor is fully
authorized and empowered to grant a security interest in said property and to
transfer the property as provided hereunder; and that no action will be taken
to cause the property pledged hereunder to constitute less than fifty-one
percent (51%) of the capital stock of WKKB, Inc. nor to restrict or adversely
affect Secured Party's rights to obtain ownership of said property as provided
for hereunder.

4.   Debtor assumes full responsibility for the preservation of his interest in
the property pledged hereunder, including taking all steps necessary to
preserve his or Secured Party's rights therein.  Secured Party shall have no
responsibility or liability for the loss, deterioration in value or destruction
of all or any of such property, whether by reason of market conditions, passage
of time or otherwise.

5.   Upon default by Debtor in the payment or performance of any of the terms
and obligations of the Put Option Agreement or this Agreement, Secured Party
shall have the right to declare any and all amounts due and owing by Debtor to
Secured Party to be immediately due and payable in full, and shall have the
right to take and possess the property pledged hereunder as its own, and shall
have all other rights and remedies provided by law (including those of a
secured party under the Uniform Commercial Code).  Secured Party may sell the
property pledged hereunder to satisfy the indebtedness of Debtor, or may retain
the property pledged hereunder in its own name and for its own use for such
purpose, or any combination of the foregoing as Secured Party determines in its
sole discretion.  In the event Secured Party retains all or a portion of the
property pledged hereunder as its own in satisfaction of part or all of the
indebtedness of Debtor, Secured Party shall have no obligation to Debtor by
reason of the value of the property pledged hereunder exceeding the amount of
the indebtedness due, and Debtor hereby expressly waives any and all rights he
may have at common law or under the Uniform Commercial Code, or otherwise, for
appraisal of the property pledged hereunder or for any return of any excess
value of said property over the indebtedness due.  Debtor hereby consents to
and covenants that the property pledged hereunder shall be deemed to be of
equal or lesser value than the indebtedness owed by him, and that he shall be
entitled to no further rights in said property should Secured Party elect to
transfer title to said property to its own name as provided herein.

6.   Debtor hereby expressly waives demand, presentment and notice of protest
or dishonor, and consents to any extension, postponement or renewal of the
indebtedness secured hereby, or to any substitutions, exchange or release of
all or part of the security for said indebtedness, and to the release,
discharge or suspension of any rights or remedies against any person who may be
liable for the payment of said indebtedness, all without prior notice to
Debtor.  Any requirement of reasonable notice prior to the disposition or
taking of any or all of the property pledged hereunder shall be met if Secured
party sends such notice by first class mail to Debtor at the address shown
below at least five (5) days prior to the date of any such sale, taking or
other disposition, or other event giving rise to the required notice.

7.   Secured Party shall not be required to pursue any other remedy nor to
pursue any other party prior or as a condition to its enforcing its rights
hereunder, it being understood that the pledge and security interest created
hereby is primary, subject to no other condition, precedent or otherwise.  Any
failure or delay of Secured Party to exercise any right hereunder shall not be
construed as a waiver of the right to exercise the same or any other right at
any time.
